9 Best 15 Inch Deep Microwave | Depth Before Wattage Every Time

Specs are compiled from manufacturer listings and verified buyer reviews and can change over time — please confirm the key details on the product page before buying.

A quick note on sizes: not every pick below is the exact size or number you searched — where the exact one is scarce, the nearest same-type option that serves the same purpose is included so you get real, in-stock choices. Each pick’s actual specs are listed.

If your counter is shallow, the depth of the microwave decides everything — not the wattage, not the brand. A unit that hangs over the edge of a narrow counter is a daily annoyance you cannot fix later, so the smart move is to measure your space first and shop depth second. This guide covers nine countertop microwaves that sit close to 15 inches deep, and every pick here has been matched to that footprint. One honest note before you read on: this list uses flexible, human-like matching for a roughly 15-inch depth, so it accepts units between about 14 and 16 inches deep and rejects the deep 17-to-20-inch models outright. So not every pick is exactly 15 inches deep, but each one fits the same shallow-counter slot.

I’m Mo Min — the founder and writer behind Non Toxic Blog. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.

All nine picks share one job: fitting a narrow counter without giving up real cooking power. If you want the shortcut, the BLACK+DECKER sits at 4.5 stars across 700+ owners and still fits a prebuilt cabinet. Read on for the rest of the best 15 Inch Deep Microwave picks.

How To Choose The Best 15 Inch Deep Microwave

Depth is the one number you cannot work around. Everything else — wattage, presets, child lock — you can live with. A microwave that sits proud of a shallow counter or blocks a cabinet door is the mistake people make most, and it is the easiest one to avoid.

Measure the slot before you read a single spec sheet

Pull a tape measure across your counter from the wall to the front edge, then subtract an inch or two for clearance. A depth-close unit like the Frigidaire, which runs 14.47 inches deep, leaves breathing room where a 17-inch or 20-inch model simply will not fit. Width and height matter too — a taller unit can bump a cabinet above it, and a wider one can crowd the toaster.

Match wattage to what you actually heat

Nine hundred watts handles leftovers, frozen dinners, and popcorn without drama. A thousand watts shaves time off dense foods like a frozen burrito or a casserole. The jump from 900W to 1000W is real but modest — the Chefman 1000W stainless unit versus the BLACK+DECKER 900W model is exactly that kind of step. Choose the lower wattage if counter space is the constraint, and the higher if speed matters more.

Check the cavity, not just the case

A 0.9 cubic foot cavity fits a full-size dinner plate in most units here; a 1.1 cubic foot cavity fits a large round casserole with room to spare. If you mostly reheat single portions, the smaller cavity is lighter and easier to slide out for cleaning. If you cook for two or more, the extra tenth of a cubic foot is worth the slightly larger footprint.

In‑Depth Reviews

★ Best Overall

1. BLACK+DECKER Countertop Microwave Oven 0.9 Cu Ft

Our pick — 4.5★ from 700+ verified ratings; the strongest balance of quality and price.

6 Auto MenusChild Safety Lock

The cabinet-slot specialist that slides in and just works

If you have a prebuilt microwave cubby — the kind built into a cabinet run — this is the one to buy first. It measures 13.2 inches deep and 18.6 inches wide, so it drops into narrow slots where 17-inch and 20-inch deep units cannot go. And it still holds a full-size dinner plate plus a 2-quart dish on a removable turntable that accepts a 10-inch pizza, which is more usable interior than the footprint suggests. Buyers report it “fits prebuilt cabinet (18.6×13.2×10.7, 0.9 cu ft), fits full-size dinner plates and 2qt dish.”

You get 900 watts of cooking power (the rate of energy the unit puts into your food per second) with 10 adjustable power settings — low enough to melt butter without scorching it, high enough to reheat a frozen entree fast. Six pre-programmed auto menus cover popcorn, potato, pizza, frozen vegetables, beverages, and dinner plates, so you press one button instead of guessing a time. One-touch start begins cooking with a single press. The 120V-60Hz voltage rating is standard US household power, so it plugs into any kitchen outlet.

What wins people over is the all-round quality of the thing. It is the single most praised attribute here by a wide margin, with size and counter-friendly fit running close behind. Owners describe the mute option (hold keypad 8 to silence the beeps) as a small mercy in a quiet house, and the large display is easy on older eyes. One owner bought it so a father who can no longer reach an over-counter unit could keep cooking — compact enough to leave counter space free and light enough to slide out for cleaning. The honest trade-off is the door — you push it shut by hand rather than press a button, which one buyer called out as their only complaint. Child lock also splits opinion; some love it, some find the two-step open up fussy, though the instructions show how to disable it if you do not want it. An occasional unit fails early, as happens in this category. Rated 4.5 out of 5.

Where it earns its keep

  • 13.2-inch depth fits prebuilt cabinet slots and shallow counters
  • Holds full-size dinner plates and a 2qt dish on a 10-inch turntable
  • Six auto menus — popcorn, potato, pizza, frozen veg, beverages, dinner plates
  • Mute the beeps by holding keypad 8; memory function recalls your favorite settings
  • Two-step child lock can be disabled when you don’t need it

What to know before you buy

  • Manual push-to-close door — no release button
  • Child lock draws mixed feelings; some find the open up steps fussy
  • Stainless exterior shows fingerprints in daily handling

Made for: anyone buying for a pre-cut cabinet opening or a shallow counter in a small kitchen, dorm, or apartment.

Think twice if: you want a press-button door release, which this model does not have.

Best Value

2. Chefman Countertop Microwave Oven 0.9 Cu. Ft., 900 Watts

Mute ButtonEco Mode

The black box that runs quiet and never wakes the kids

This is the pick for anyone who microwaves at odd hours — a night-shift worker, a parent with a sleeping baby, a light sleeper in a small apartment. The reason is simple: there is a mute button that kills the beeps entirely, and Eco Mode lets you shut off the display when it is not in use. At 13.27 inches deep it tucks into a shallow counter without hanging over the edge, and the flat black finish wipes clean with a damp towel.

At 900 watts it matches the BLACK+DECKER above, but the pitch here is convenience rather than fit. Six presets cover popcorn, pizza, beverages, veggies, potatoes, and leftovers, plus there is a +30 seconds button for a quick top-up without re-entering anything. Ten power levels range from a low melt setting up to full power. The glass turntable is top-rack dishwasher safe, which is a genuinely useful detail — no hand-scrubbing after a greasy plate. Frequency runs at 2.45 GHz, the standard microwave band.

The performance is what carries this one — it draws the largest share of favorable comments by a wide margin, and ease of use ranks second. People describe setting it and forgetting it: even heating, quick-start buttons that work on the first press, a large display that one 66-year-old owner singled out as easy to read. It also runs quietly, which owners note repeatedly. The cautions are real but modest. The keypad is on the firm side — a couple of buyers mention needing a solid press, and one keeps the unit against a wall so it does not push back. The size reads smaller than some expect, so check your plate diameter. And a small number of units fail early, which is why a protection plan is worth considering on this one. The included child lock on the handle can feel stiff to some owners. Rated 4.2 out of 5.

The quiet-hours call: if silence and energy savings matter more to you than raw speed, this earns its spot — the mute button and Eco display shut-off are features the pricier picks here skip.

The firm-press factor: budget about a second of hold on the keypad, and keep the back of the unit near a wall so it does not skate backward when you press.

Worth grabbing: for apartments, dorms, offices, or any kitchen where a beeping microwave at 11 p.m. is a problem.

Look elsewhere: if you want a large cavity for big casseroles, or a soft-touch keypad.

Top Performer

3. Chefman Countertop Microwave, 1.1 Cu Ft, 1000W, Stainless Steel

1000 WattsDishwasher-Safe Turntable

A tenth of a cubic foot more room without losing the shallow fit

You get a bigger interior here. This Chefman steps up to 1.1 cubic feet and 1000 watts while staying at 14.47 inches deep, so you get a bigger cavity — big enough for a 10-inch dinner plate with room around it — without blowing past the shallow-counter limit. For comparison, the 0.9 cubic foot Chefman above tops out around a standard plate; this one leaves margin. The width climbs to 20.1 inches, so measure your counter run before committing.

Power sits at 1000 watts with 10 power levels, and the defrost system handles both time and weight — the weight mode is the one that matters when you pull a frozen chicken breast out at 6 p.m. and want it thawed evenly rather than cooked at the edges. Three one-touch presets cover popcorn, beverages, and leftovers, and there is a +30 seconds button for the odd top-up. The stainless interior and glass turntable are dishwasher safe. A mute option silences the beeps for late-night use, and the child safety lock keeps small hands out — pull up on the top edge of the handle to release it.

Owners rave about the performance first, with functionality a close second. People describe it as a great buy: compact, easy on the counter, and reliable. One owner noted that it holds a 10-inch dinner plate and the interior is white, which makes it easier to see what you are cooking. Another pointed out that it does not blow a fuse when other appliances are running, which matters in older kitchens with tight wiring. On the honest side, the noise level splits opinion — some find it quiet, some find it loud when running, and the same goes for ease of use. A rare unit reported a serious fault after about a year, which is worth knowing but is not the norm at this rating level. Rated 4.4 out of 5.

The capacity jump: that extra tenth of a cubic foot is the whole reason to pick this over the cheaper Chefman — it is the difference between fitting a dinner plate snugly and fitting one with room to rotate.

Noise is the wildcard: most owners call it fine, but the ones who care about quiet describe it as louder than expected, so if silence is your priority, weigh the mute-button model instead.

Best fit: kitchens where a full-size plate needs to rotate freely but the counter is still only about 15 inches deep.

Not the pick: if your counter run is under 21 inches wide, or if silence is non-negotiable.

Compact Pick

4. Frigidaire 1.1 cu.ft. Countertop Microwave Oven, Stainless

1000 WattsAuto-Cook Menus

The office-lunch workhorse that keeps its footprint honest

This one suits a workplace break room, a dorm, or a second kitchen. It gives you 1.1 cubic feet and 1000 watts of output at 14.47 inches deep, which lands squarely in the shallow-counter balance. The white interior is the standout cosmetic detail — it contrasts with the black and stainless exterior and makes it easy to spot spills before they bake on. A curved handle on the front opens the door with a pull, and an interior light lets you check on food without breaking the seal.

Auto-cook functions cover popcorn, potato, pizza, frozen veggies, beverage, and reheat, plus a cook-by-weight mode for defrosting. There is a digital clock, a kitchen timer, and a child safety lock to prevent unsupervised operation. Energy consumption is listed at 5 kWh, and the heating method is standard microwave radiation. If you want the fully-programmed quick-cook experience, note that this model runs manual settings for anything under 30 seconds — you press the 30-second button and stop it manually rather than dialing in 15 seconds.

Functionality is what buyers cheer for, with size a distant but positive second. A long-term Frigidaire owner called it — in their words — the right size, the right power, and a generous pick. Another noted it fits average plates and bowls plus a small round covered casserole, which is the realistic upper limit here. Where it stumbles is the door and button behavior: a few owners find the requirement to hit stop before opening the door annoying, and one unit arrived defective with an unresponsive touchpad. Those are the exceptions at this rating, but they are worth a heads-up if you want zero-fuss controls. Rated 4.1 out of 5.

What it nails: a genuinely useful 1.1 cubic foot cavity in a 14.47-inch-deep shell is not easy to find, and the 1000 watts matches the slightly larger competition.

The one quirk: you cannot program a time under 30 seconds directly, so short bursts need a manual stop — minor, but you will notice it daily if you reheat coffee.

Pick this if: you want a full-power, full-size-cavity unit that still hugs a shallow counter in a break room or small kitchen.

Skip the hassle if: the stop-then-open door routine would drive you up the wall.

Best for Small Kitchens

5. GE Countertop Microwave Oven, Compact 0.9 Cubic Ft.

7 Auto SettingsChild Lock

A white-bodied runner that heats faster than its label suggests

If your kitchen runs white — white cabinets, white appliances — this is the one that will not stand out for the wrong reason. It is a 0.9 cubic foot, 900-watt unit measuring 14.5 inches deep, 19 inches wide, and 11.5 inches tall, giving you a compact footprint without sacrificing the cavity. The clearance requirements are specific: leave 3 inches on each side and above, 1 inch at the rear, and keep the bottom unobstructed so airflow does the cooking justice.

Controls are simple by design. Seven convenience cook settings plus one-touch express keys cover beverages, defrost, pizza, popcorn, and reheat without a manual lookup. Both manual and auto defrost modes adjust time and power so frozen food thaws evenly — no overcooked edges with a cold center. There is a mute option and an independent kitchen timer, plus the interior light and electronic keypad. The child lock disables easily when adults are the only ones in the house.

The quality build is what stands out most in owner feedback, with performance a solid second. One owner points out that the 900 watts actually heats faster than the 1000-watt unit it replaced — wattage is not always the whole story — and that the cavity fits a 10.5-inch casserole. What people appreciate beyond the basics: you can turn off the clock display for a cleaner look, the kitchen timer works independently, and the buttons are easy to press. The trade-offs are honest. The turntable does not return to a set starting position, which some find awkward when loading a rectangular dish. The timer controls use the start/pause button in a way that some find unintuitive. A few owners flag durability concerns typical of modern compact appliances, and the noise level draws a mixed read. Rated 4.3 out of 5.

Color-coordinated function: the white finish is more than cosmetic — it ties into small kitchen themes, and the 14.5-inch depth keeps it off the edge of a narrow counter.

Quirky but workable: the turntable’s parking position takes getting used to, and the timer flow is not the most intuitive — a two-week adjustment period, not a dealbreaker.

Ideal for: white-themed small kitchens, dorm rooms, offices, and apartments where you want the GE name without the countertop bulk.

Not the one: if you want a press-button door release or a turntable that stops where you left it.

Most Widely Owned

6. Commercial Chef 1.1 Cu. Ft. Countertop Microwave Oven, CHCM11100SSB

1000 Watts10 Power Levels

The one everyone already owns — and the one to learn from

This is the most widely owned microwave on the list, and the reviews read like a long-term field study. It is a 1000-watt, 1.1 cubic foot unit at 15.44 inches deep — just over the 15-inch line but still within the flexible range this list uses. It weighs 28 pounds, which is on the heavier side, so it stays put when you open the door. The compact 21 by 15.44 by 11.3 inch frame fits large plates and takes up less counter than its capacity suggests.

The controls are the old-school kind that keep working. A push-to-open door with no handle, a clear keypad after you peel the protective film off, six one-touch menus, and both weight and speed defrost. Digital controls run from 30 seconds up to 99 minutes, with a kitchen timer and an audible signal when cooking finishes. There is no learning curve — owners of all ages figure it out in minutes, which is exactly why it ends up in so many kitchens and break rooms.

Durability is the draw here. Long-term owners measure this in years, not months, and two-plus years of daily use with mitts and steam is a common story. One buyer sums up the everyday experience: hot popcorn, melted butter, reheated leftovers, no fuss, and a smooth interior that wipes clean with lemon juice and water. The single most-praised attribute is its compact, no-bells-and-whistles design that just works — and it shows in the sheer number of households running one. The honest caveats: it is light enough that the whole unit can tip when you pull the door open, so it needs a level, stable surface; the baked-enamel interior wants drying after steaming if you want it to last; and no instruction booklet ships in the box — you download the PDF.

The long-game strengths

  • 1000 watts and 10 power levels at 15.44 inches deep
  • Push-to-open door — no handle to break
  • 30 seconds to 99 minutes on the digital timer, plus 6 one-touch menus
  • Owners mention working units after two-plus years of daily use
  • Genuinely simple for older users — no learning curve

What owners flag

  • Light at 28 pounds — the unit can tip forward when you open the door
  • No instruction booklet in the box; download the manual
  • Interior wants wiping and airing after steaming to hold up long-term

For the long haul: anyone who wants the microwave equivalent of a well-used kitchen knife — basic, sturdy, and unlikely to be the thing that fails.

Know before you commit: it is the widest pick here at 21 inches, so measure your counter run, and give it a level surface.

Best for Small Counters

7. Kenmore KMCMWP09S2-09 Countertop Microwave, 900 Watt, 0.9 Cu Ft

6 Preset MenusExpress Cook

Six presets and a slim 13.56-inch profile in a full stainless shell

This is the pick for anyone who owns other Kenmore appliances and wants the microwave to match. It measures 13.56 inches deep and 19 inches wide — genuinely compact — while still delivering 0.9 cubic feet of capacity. Six preset menus cover popcorn, potato, pizza, frozen dinner, beverage, and reheat, and the one-touch start handles 30 seconds plus 1 through 6 minutes in a single press. Defrost works by time or by weight, whichever your food suits better.

The controls are the low-noise type: a clock, a kitchen timer, and a straightforward panel that does not require a manual to run. The stainless steel shell wipes clean easily, and the interior is stainless too, so greasy splatters do not set into a porous surface. At 900 watts with 60 hertz operation, it handles daily cooking and reheating without drama. The 0.9 cubic foot cavity is enough for a standard dinner plate or a pair of soup bowls, but not for a big casserole — that is the honest limit.

Owners come back to praise quality and ease of use, with the aesthetic and space-saving footprint running close behind. One customer finds the smaller cabinet fully adequate for their cooking and reheating, and single-portion defrosting of fish, chicken, and steamed vegetables is exactly the use case it nails. If you already trust the Kenmore name, the brand consistency is part of the appeal. The friction points owners mention center on the door latch and reliability rather than the cooking itself — a small share of users see the latch give out inside the first year or so, which is the pattern to know about. The child safety lock also needs to be open up every session if it is active, which some owners find tedious and others find reassuring. It is a little smaller than some shoppers picture from photos. Rated 4.2 out of 5.

The Kenmore system pull: if your kitchen already runs Kenmore, this slips into the lineup with matching design and familiar control logic — the microwave is the appliance you see most, so matching counts.

The latch caveat: treat the door handle gently — it is the single component with the most durability complaints, and the door latch is the failure point most worth watching.

Reach for this: if a 13.56-inch-deep footprint is the priority, you cook single portions, and a matching Kenmore kitchen appeals to you.

Consider elsewhere: if you regularly heat family-size dishes, or if the door-latch watchfulness would bother you.

Best Sensor Cook

8. TOSHIBA Countertop Microwave Oven with Smart Sensor, 1.1 Cu.Ft, 1000W

13 Preset MenusSmart Sensor

Sensor cooking that reads your food and stops on its own

If you have ever stood over a microwave guessing whether burritos are hot in the middle, this pick solves that. It uses a smart sensor (a small detector that reads the moisture coming off the food as it heats) to adjust cooking automatically, so you do not enter a time at all. That is the difference between sensors and presets — the presets in the cheaper picks run a fixed time, and the sensor here adapts. The 1.1 cubic foot cavity, 1000-watt output, and 14.8-inch depth keep it in the shallow-counter zone while providing room for a real meal, and the 12.4-inch glass turntable fits a big plate.

Thirteen preset menus and 10 power levels give you a broad spread of options, and the memory function saves your most-used dish settings for one-press retrieval. Defrost works by either weight or time. There is a mute mode for late-night use, and a two-step child lock for safety — refer to the manual for setup. Input power is 1600 watts while output is 1000, which is normal for this class. The black stainless exterior gives it a modern look that blends with most kitchen decor.

The size is what buyers consistently rave about — it fits standard dinner plates but does not overcrowd the counter. Functionality runs second, with owners praising the even reheating of awkward foods like tamales, burritos, and oatmeal. The quiet operation is mentioned often, and the flatbed design (no rotating turntable to clean around) makes the interior easy to wipe down. The buttons need a firm press, and some of the sensor labels are cryptic — one owner noted the button hard to press and the labels unclear; another wanted a different handle mechanism. On the durability front, a few owners express doubt about how long it will last, which is worth weighing but is not the typical experience at this rating level. Rated 4.5 out of 5.

what separates it

  • Smart sensor adjusts cooking automatically instead of running a fixed timer
  • 13 preset menus and 10 power levels for very broad cooking coverage
  • Memory function for one-press access to your favorite dish
  • Flatbed interior with no turntable to clean around
  • Quiet operation, mute mode, 1000W output in a 14.8-inch-deep case

Where it asks for patience

  • Buttons need a firm, deliberate press — light taps do not register
  • Some sensor labels are cryptic until you read the manual
  • Durability is a question mark for a minority of owners

Best for: anyone who wants the microwave to decide when the food is done — reheating, defrosting, and one-dish meals without setting a timer.

Not ideal if: you like feather-light keypad presses or want an obvious labeled button for every function.

Premium Pick

9. LG Countertop Microwave, 0.9 cu. ft., Smart Inverter, NeoChef, 1000 Watts

Smart InverterEasyClean Interior

Precise inverter power in a shallow-case shell

This is the top-tier pick for anyone who wants steadier heat, not just faster heat. The Smart Inverter is the defining feature — it controls the cooking power smoothly instead of pulsing on and off at full blast, which is why defrosting and melting behave more predictably here. It gives you a full 1000 watts of output and 10 adjustable power levels in a 0.9 cubic foot cavity that measures just 14 inches deep. The 12-inch turntable accepts a range of dish sizes without eating the whole cavity, and the stainless shell looks like a proper built-in even though it sits on the counter.

Auto Cook covers seven food types — bacon, fresh vegetable, frozen entree, frozen vegetable, oatmeal, potato, and rice — plus auto and rapid defrost modes. The glass touch control panel (branded SmoothTouch) is flat and wipes clean without crevices collecting crumbs. There is an Ez On (+30 seconds) button and a child safety lock. The EasyClean interior is designed to release food and grease with a quick wipe rather than a scrub. The compact case at 14 inches deep, 18.75 inches wide, and 10.69 inches tall keeps it off a shallow counter’s edge.

The performance is what owners praise most, and the size is the close second — big enough for dinner plates, small enough to fit most tight counters. Owners describe even heating on frozen burritos, accurate heating times, and a bright interior light. The 12-inch turntable completing one rotation per minute is a small detail some users notice and like, because it means the plate finishes with the handle at the front. The trade-offs: the start button is on the firm side and some owners find the manual bare-bones, with cryptic numbered features that need translation. A minority report an early failure, but the general experience trends toward reliable and quiet. Rated 4.2 out of 5.

Why inverter matters: smooth power delivery is the reason this one melts butter without scorching and thaws without cooking the edges — genuinely useful, and not something a microwave offers.

The convenience tax: the manual is thin and the numbered features are not self-explanatory, so plan on a slow first week while you learn the button map.

The premium call: for anyone who cooks by feel and wants the microwave to cooperate instead of pulsing, with shallow-counter fit to match.

Look at the mid-range instead: if you only reheat coffee and leftovers — the inverter advantage shines on from-scratch cooking, not simple warming.

Understanding the Specs

Depth — the number that decides your kitchen fit

Depth is measured from the back wall to the front of the door. A 15-inch-deep microwave will not overhang a shallow counter, while a 17-to-20-inch unit leaves you no room to work. If your counter measures 15 inches front to back, aim for a 13-to-15-inch unit; anything deeper will stick out into your prep space. This is why the shallow-counter picks here cluster between 13.2 and 15.44 inches — each one respects that constraint.

Wattage — what 900 versus 1000 really means

Wattage is how much cooking power the unit puts into your food. Nine hundred watts handles leftovers and frozen dinners fine; 1000 watts shaves a little time off dense foods like a casserole or a thick cut of meat. The difference is real but modest — a 100W step is meaningful for speed, not transformative. If counter depth is the priority, 900W is plenty. If you want faster results on from-scratch cooking and dense foods, 1000W earns its bigger footprint.

Capacity — matching the cavity to how you cook

Capacity in cubic feet measures the interior cooking space, not the counter footprint. A 0.9 cubic foot cavity fits a standard dinner plate; a 1.1 cubic foot cavity fits a large round casserole or a bigger plate with room around it. If you cook for one, 0.9 is plenty and keeps the unit lighter. If you cook for two or more, or heat casseroles, the extra tenth of a cubic foot is worth the slightly larger case.

Presets, sensors, and child locks — which features you’ll actually use

A preset runs a fixed cooking time for a listed food — popcorn, potato, pizza, and so on. A sensor reads the food’s moisture as it heats and adjusts automatically, so you skip the time entry. A child lock disables the controls to prevent unintended use; on some models it must be open up each session, on others it can be disabled entirely. Pick presets for one-button cooking, a sensor for hands-off cooking, and a child lock if kid-safety comes first.

FAQ

Will a 15 inch deep microwave fit in a standard cabinet slot?
Often yes, if the cabinet opening is at least about 19 inches wide and 11.5 inches tall. The BLACK+DECKER, for example, is 13.2 inches deep and 18.6 inches wide, and customers note it fitting a prebuilt cabinet. Measure the interior opening before ordering, and check that the door has room to swing open past the cabinet frame.
Is 900W enough or should I get 1000W?
For leftovers, frozen dinners, and popcorn, 900W is plenty — it will heat everything you put in it. A 1000W unit shaves time off dense foods like casseroles or frozen burritos. One owner of the GE 900W model reported it heating faster than the 1000W unit it replaced, so wattage alone does not tell the whole story. Pick 1000W if speed on thick foods matters; stick with 900W if counter depth and weight are the bigger constraint.
How do I measure my counter for a 15 inch deep microwave?
Measure the depth from the back wall to the front edge of the counter, then subtract an inch or two for clearance and cords. Width and height matter too — leave room for the door to swing and clearance for airflow, typically a few inches on the sides and top, plus an inch at the rear. If your counter measures 15 inches deep, a 13-to-15-inch unit is the safe pick.
Do microwave child locks need to be disengaged every time?
It depends on the model. On the Kenmore, the child lock needs open up every session if active, which some owners find tedious and others find reassuring. On the BLACK+DECKER and GE, the lock can be disabled entirely when you do not need it. If you do not have small children, look for a model where the lock is optional rather than always-on.
Is sensor cooking worth it over regular presets?
Yes, if you reheat uneven foods like burritos, tamales, or oatmeal. A sensor reads the moisture coming off the food and stops cooking when it is done, so you never enter a time. The TOSHIBA here does this with 13 preset menus. Regular presets simply run a fixed time, so denser foods can come out cold in the middle. For simple reheating, a fixed preset is fine; for anything with mixed density, the sensor earns its place.
Can a compact 0.9 cu ft microwave hold a full dinner plate?
Yes, in most models here. The BLACK+DECKER 0.9 cubic foot unit holds a full-size dinner plate and a 2-quart dish on its 10-inch turntable, and buyers specifically report fitting a 10-inch pizza. The TOSHIBA 1.1 cubic foot unit fits a standard dinner plate with more room, and its 12.4-inch turntable takes oversized dishes. Check the plate diameter against the turntable, which is the real limit.
Do these microwaves have a mute option to kill the beep?
Several do. The Chefman 0.9 cubic foot model has a dedicated Audio Button that silences the beeps entirely, and the BLACK+DECKER mutes if you hold keypad 8. The GE and TOSHIBA also offer a mute mode. If you microwave late at night or live in a small space with others sleeping, this is the single most useful feature to confirm before buying.
How long do compact countertop microwaves typically last?
Long-term reviewers point out several years of service, and some models here have been running daily for two-plus years. But failure does happen — one purchaser of a Chefman 1.1 cubic foot unit reported a fault after about a year, and a Kenmore buyer reported a latch failure within the first six months. Most units at this rating level hold up well; treat the door latch and the keypad as the two components worth care.
Will a quiet microwave wake the house at night?
The microwave itself hums quietly, so the wake-up issue is nearly always the beep, not the motor. The Chefman 0.9 cubic foot model has a mute button and Eco Mode to silence the display, and the GE and TOSHIBA include mute options too. Choose a model with a mute option and you can cook at any hour without a sound. Noise level on the fan is mixed across all models here — nothing loud, but nothing silent either.
Is a flatbed microwave better than one with a turntable?
Each has strengths. A flatbed like the TOSHIBA has no rotating dish, so more interior volume is usable and cleanup is faster — owners describe it reheating tamales and oatmeal evenly. A turntable like the LG’s 12-inch platform rotates the food itself, which helps with even heating and lets you load square or rectangular containers confidently. Neither is superior; pick flatbed for cleanup simplicity and turntable for rectangular dish fit.
How much power does a countertop microwave draw?
A typical 900-watt output unit draws around 120 volts at 60 hertz — standard US household power, plugging into any kitchen outlet. A 1000-watt output unit like the TOSHIBA lists an input power of 1600 watts, which is normal for this class. Watch your total kitchen circuit load if you are running the microwave alongside a toaster or kettle; the Frigidaire’s energy consumption is listed at 5 kWh, which is typical for this category.

Final Thoughts: The Verdict

For most kitchens, the 15 inch deep microwave winner is the BLACK+DECKER Countertop Microwave Oven 0.9 Cu Ft because it fits prebuilt cabinets and shallow counters while still holding a full-size dinner plate, a 2-quart dish, and a 10-inch pizza on its turntable. If you want more cavity room without giving up the shallow fit, the Chefman 1.1 Cu Ft Stainless gives you a bigger interior and 1000 watts for the same counter silhouette. And for quieter kitchens with a matching appliance collection, the Commercial Chef 1.1 Cu Ft has been running in homes long enough that its two-plus-year reliability stories are common. If you do not yet own a microwave, start with the BLACK+DECKER: 4.5 stars, a large owner base, and features that keep up with the premium picks.
