If your counter is shallow and a full-size microwave would hang over the edge, you want a unit whose depth sits around fifteen inches — deep enough to hold a dinner plate, shallow enough to actually leave counter space in front of it. That depth range is the whole point of this list, and the picks below are sorted by how well they balance a compact footprint against real cooking power.
I’m Min — the founder and writer behind Gadgets Feed. 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.
Depth is the spec that decides whether a countertop microwave fits your kitchen at all, so every pick here is measured on that first. This rundown covers the best 15-inch deep microwave options, ranked by how much usable space they leave you.
Our Picks at a Glance
How To Choose The Best 15-Inch Deep Microwave
The number that gets overlooked is depth. Most shoppers read the cubic-foot capacity and stop there, then get the unit home and find it juts past the edge of a shallow counter. Depth is measured front to back on the outside of the cabinet, and it is the measurement that decides whether the door can swing open without hitting a fridge or a wall.
Measure the depth, not just the capacity
A compact unit that sits around fifteen inches deep can still hold a standard dinner plate, because interior space and exterior depth are different numbers. Capacity in cubic feet tells you how much food fits inside. Exterior depth tells you whether the machine fits your counter at all. Check both before you buy, and measure your counter with a tape before you commit.
Match wattage to what you actually cook
Wattage is the cooking power. A 700-watt unit reheats a plate of leftovers fine but takes longer on a frozen dinner. A 1000-watt or 1200-watt unit pushes through frozen food faster and heats more evenly. If you mostly reheat coffee and leftovers, lower wattage is plenty. If you cook from frozen regularly, spend for the higher number.
Leave room for airflow
Compact microwaves need breathing room. GE, for example, asks for 3 inches of clearance on each side and above, 1 inch at the rear, and a fully unobstructed bottom. Skip that and the unit can run hot and underperform. A shallow-depth microwave is only a win if you still give it that gap.

In‑Depth Reviews
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.
The compact 900-watt workhorse that tucks into a shallow counter and still holds a whole dinner plate.
Start with the depth: 13.2 inches front to back, which slides into the tightest counter slot in this lineup without overhanging the edge. That is 18% shallower than the Chefman 1.1 Cu Ft at 14.47 inches, and 18% narrower at 18.6 inches versus the Chefman’s 20.1 inches. It stands under the 15-inch mark with room to spare, so it clears a cabinet edge even on a narrow counter run.
Inside, the 0.9 cubic feet and 900 watts mean it heats a frozen entrée or a plate of leftovers without drama. Six pre-programmed auto menus cover popcorn, potato, pizza, frozen vegetables, beverages, and dinner plates, and the ten adjustable power levels let you drop to a gentler setting for defrosting. A one-touch start button skips the number-pad routine for quick reheats, and a two-step child lock can be deactivated with the included instructions when it is not needed.
The noise can be muted by holding the “8” button, a small touch that matters in an open-plan kitchen or a late-night snack run. Buyers consistently point to the fit and the compact size as the reasons they chose it, with feedback like “Love it. Have small space and fit perfectly” and “It is a little small but it’s perfect for me.” Build quality and appearance also come up as recurring positives. The trade-off to know: the door has to be pushed shut rather than levered with a button, and a few owners find the child lock fussy to switch off. Neither is a defect, just something to expect before you order.
What clicks on day one
- 13.2-inch depth fits counters that a full-size unit would overhang
- 900 watts and 0.9 cubic feet handle a standard dinner plate
- Sound can be silenced by holding the “8” button
- One-touch start skips the manual cook-time entry
Worth knowing before you buy
- Door must be pushed shut — no release button
- Two-step child lock can be fiddly to disable
Grab this if: you have a genuinely shallow counter and need a compact 900-watt unit that still swallows a dinner plate.
Think twice if: you want a soft-open door or a button to release the latch — this one is a manual push-shut design.
2. BLACK+DECKER Countertop Microwave Oven 0.7 Cu.Ft, 700W
The smallest footprint here at 12.3 inches deep — built for counters where every inch is spoken for.
If your counter is tight enough that the microwave barely fits, this is the shortest footprint in the lineup: 12.3 inches deep, 17.1 inches wide, 9.5 inches tall. Against the Chefman 1.1 Cu Ft, it is 18% shallower, 18% narrower, and 26% shorter, with a 0.7-cubic-foot interior versus the Chefman’s 1.1. You lose cooking volume but you buy back real counter space, which is the trade most small-apartment shoppers are making.
The 700 watts and ten cooking power levels are designed for reheating and lighter defrost work rather than heavy cooking. Express-cook shortcut buttons start heating without fiddling with the keypad, and the multi-stage function can chain a defrost step into a reheat step automatically for frozen meals. Six presets cover popcorn, potato, pizza, frozen vegetables, beverages, and dinner-plate reheat, and the fingerprint-resistant black finish keeps the front looking clean between wipe-downs.
Owners describe it as “well-made” and “powerful” for its size, with several noting the rotating glass plate gives even heating and that it “outperforms higher-rated name brand” units at a lower cost. The recurring caveat — and it shows up as the most-mixed topic in the feedback — is the door lock: some owners love the safety feature, others find it needs a beat of getting used to. A minority find the LED clock too bright at night. Both are quirks of the design rather than faults, so factor them in if you are sensitive to either.
Where it earns its keep: the 12.3-inch depth is the deciding number for a counter that simply will not take a larger box.
A fair word on the wattage: at 700 watts it takes longer on frozen food than the 900-watt and 1000-watt picks above — fine for reheats, slower for full meals.
Reach for this if: your counter is so shallow that no other unit here will physically rest flat without hanging over the edge.
Look elsewhere if: you regularly cook from frozen and want the higher wattage of the 900-watt and 1000-watt options higher up this list.
3. Chefman Countertop Microwave, 1.1 Cu Ft, 1000W
A 1000-watt, 1.1-cubic-foot unit that keeps a shallow 14.47-inch profile while still fitting bigger dishes.
The unusual thing here is the combination: 1.1 cubic feet of interior and 1000 watts of cooking power in a body that measures just 14.47 inches deep and 20.1 inches wide. That depth still sits under the fifteen-inch line, so it slots into a shallow counter even though it holds more food than the 0.9-cubic-foot BLACK+DECKER and GE units further up. The 1.1-cubic-foot size means a full plate or a casserole dish fits without angling.
Three one-touch presets — popcorn, beverages, and leftovers — cover the quick jobs, and a +30 second button adds time without re-entering a cook cycle. Ten power levels span from a light setting for melting butter up to full power, and the stainless-steel interior has a dishwasher-safe glass turntable. A mute option silences the beeps for quiet kitchens, and the child lock sits on the handle so the door does not open by accident.
Owners who need the extra room say it clears bigger items and reheats quickly, with one noting the defrost mode “actually doesn’t cook the meat” — the even, low-power thaw is a real strength of the 1000-watt setup. The one downside that surfaces in feedback is the quick-set buttons, which need a firm press. If you have limited hand strength, that tactile stiffness is worth knowing about ahead of the buy. Otherwise, this is the pick for shallow-counter shoppers who want the most interior room.
The value read: you get the largest interior in the sub-15-inch deep group without stepping up to a wider cabinet — the 20.1-inch width is the one dimension to verify against your counter.
The honest trade: quick-set buttons take a hard press, and the mute button means you can quiet the beeps but not the physical door thunk.
Fits you best if: you want the most cooking room in a shallow-depth body and value a fast defrost that thaws without cooking the edges.
Reconsider if: you prefer a light-touch keypad — the quick-set buttons here need a solid push.
4. GE Countertop Microwave Oven, Compact 0.9 Cubic Ft., 900-watt, White
The white-finish compact that fits a shallow counter and a white kitchen theme in one move.
This GE model fits shallow counters at 14.5 inches deep, 19 inches wide, and 11.5 inches tall — that depth clears the fifteen-inch threshold with half an inch to spare, so it sits comfortably without hanging over the edge. Inside, the 0.9 cubic feet of space and 900 watts of power put it in direct competition with the BLACK+DECKER 0.9 Cu Ft, and the two are close enough that the deciding factors are the controller feel and the finish. This one wears a clean white cabinet that owners pick specifically to match a light-toned kitchen.
Seven convenience cook settings and one-touch express options handle beverage, defrost, pizza, popcorn, and reheat cycles, and the electronic keypad gives precise control over time and power. Manual and auto defrost modes adjust both time and power to thaw frozen food evenly. GE also flags a mute option that quiets the keypad beeps and lets you switch off the clock display at night, plus a standalone kitchen timer that runs independently of cooking.
Owners describe it as “small and simple” that “fits well in my kitchen,” and the fast-heating performance is a repeated theme — one notes it heats faster than a previous 1000-watt unit. The recurring honest caveat is the turntable: it does not always return to the same starting position when the cycle stops, and the timer can require an awkward start/pause press to activate. Neither affects cooking, but they are the small frictions to expect. A minority also find the controls less intuitive at first than the touch panels on competing units.
What wins here: a real mute option, a clock-display-off setting, and an independent kitchen timer — three conveniences that most compact microwaves of this size skip.
Know before ordering: the turntable stops wherever it stops, not at a fixed home position, and the timer key needs its own press.
Best matched to: a white or light-toned kitchen that wants a shallow-depth 900-watt microwave with silent operation and a clock you can switch off.
Skip over if: you want the turntable to park at the same spot each cycle — that small inconsistency is a real part of this model’s design.
5. TOSHIBA Countertop Microwave Oven with Smart Sensor, 1.1 Cu.Ft, 1000W
Thirteen preset menus and a smart sensor that reads moisture and sets the power for you.
At 14.8 inches deep, 20.6 inches wide, and 11.8 inches tall, this TOSHIBA lands inside the fifteen-inch depth range that defines this list. Its interior holds 1.1 cubic feet — the same capacity as the Chefman 1.1 Cu Ft pick, and a step up from the 0.7 and 0.9-cubic-foot units here. The stainless steel finish and black accents give it a modern look that fits under a cabinet without clashing.
The smart sensor is the headline: 13 preset menus read the moisture inside the oven and adjust power and time automatically, which takes the guesswork out of reheating different food types. Ten power levels give you fine control when you want it, and both weight-based and time-based defrost are on board for frozen items. A memory function saves your go-to settings for one-touch recall, a mute mode silences the beeps, and the two-step child lock keeps small hands from starting a cycle. The 1000 watts of output and 1600 watts of input are enough for the majority of home cooking tasks.
Owners single out the quiet operation and the fast heating, with comments like “Heats quickly, great size, great price” and “Good quality & very quiet.” The honest caveat is durability: some buyers report a failure after a few months of use, which is the one area to weigh against the otherwise strong feedback. The touch buttons also need a firm press, and some owners note the sensor labels on the panel are less obvious than they could be. Neither is a dealbreaker, but combined with the durability reports they are the points to know before you commit.
Why it earns a slot: the sensor does the thinking on reheat and defrost, which is the biggest time-saver in this whole lineup for day-to-day cooking.
The one thing to weigh: a handful of owners mention reliability issues after a few months, so this is the pick to think about a warranty on if you plan on heavy use.
Worth grabbing if: you want sensor cooking, mute mode, and 13 preset menus in a shallow-depth 1000-watt unit.
Consider another option if: long-term durability is your top concern — this model has the most mixed reliability feedback on the list.
6. LG Countertop Microwave, 0.9 cu. ft., Smart Inverter, NeoChef, 1000 Watts
Smart Inverter heat and 1000 watts crammed into a 14-inch-deep stainless body.
Inverter technology is the differentiator here. Instead of cycling the magnetron on and off at full blast, Smart Inverter varies the power smoothly, which means gentler reheating and more even results on delicate foods like defrosted lasagna. It fits the shallow-depth brief at 14 inches front to back and 18.75 inches wide, and delivers 1000 watts from a 0.9-cubic-foot interior with 10 adjustable power levels.
Auto Cook covers seven food types — bacon, fresh vegetable, frozen entrée, frozen vegetable, oatmeal, potato, and rice — while a 12-inch turntable takes a broad range of dish sizes without forcing you to trim. The EasyClean interior wipes down easily, and the glass SmoothTouch control panel keeps the front looking tidy. A child safety lock and an Ez On (+30s) button round out the everyday conveniences.
Owner feedback calls it “small but mighty” and “a perfect size for standard plates,” with the inverter heating and quiet operation drawing the most praise. Customers note no rust in the interior finish after five months of use. The recurring honest note is that the panel buttons can be slow to respond and some of the labels are less intuitive than they look, so it rewards a minute of reading the manual rather than guessing. The stainless finish also shows fingerprints, so if you keep an open kitchen you will want a microfiber cloth nearby.
What you are paying for: the Smart Inverter heating control — smooth, even power delivery that makes defrosting and reheating more predictable than a traditional on/off magnetron.
Small trade-offs: button response is occasionally sluggish and the stainless surface shows smudges easily.
Built for you if: you want precise inverter heating and an easy-clean interior in a compact 0.9-cubic-foot body.
Second-guess if: you want a strictly touch-insensitive panel — this model’s buttons take a deliberate press.
7. GE Countertop Microwave Oven, 950 Watt, 1.1 Cu. Ft., Stainless Steel
The widest and deepest pick in the lineup — check your counter before you commit to this one.
The honest heads-up first: this GE measures 15.62 inches deep, which sits just beyond the fifteen-inch nominal figure this list is built around. If your counter is truly shallow, this one is the closest fit at the top end but the least likely to leave much clearance behind. Width is 20.83 inches, height is 12 inches, and interior runs 1.1 cubic feet at 950 watts — sizeable for a countertop unit, with room for family-sized portions.
The 950 watts and six convenience cook settings plus one-touch express control keep daily reheating and defrosting straightforward, with both manual and auto defrost modes on board. GE throws in a bonus pasta cooker that fits the microwave for preparing pasta with far less stovetop time. A child lock adds safety for households with small children, and the mute option quiets the keypad beeps when needed.
Owners describe it as “sleek, medium-weight, easier to clean inside, and easy to operate,” and the stainless-steel interior has drawn praise from long-term users, with several commenting on years of reliable service. The recurring caveat is the door: it closes with a louder thunk than most modern units. The clearance rules from GE also matter more here given the extra depth — allow 3 inches on each side and above, 1 inch at the rear, and keep the bottom unobstructed.
Where it fits best: a larger counter that can absorb the 15.62-inch depth and 20.83-inch width while still leaving rear clearance — bigger portions and the pasta cooker are the payoff.
What to know: the door shuts with a noticeable clack and the extra depth eats into rear clearance on shallow counters.
Right for you if: you have counter space to spare and want the largest interior in a near-fifteen-inch-depth stainless unit with a pasta cooker included.
Better to skip if: your counter is genuinely shallow — the 15.62-inch depth here risks a tight squeeze against the wall.
8. GE Countertop Microwave, 700 Watt 0.7 Cu. Ft., Stainless Steel, GCHK07N1WSS
A compact, under-cabinet-capable 700-watt unit that keeps counter clutter off the surface entirely.
Depth is 13 inches here, 17.25 inches wide and 10.1 inches tall — an overall footprint that sits comfortably inside the fifteen-inch depth target for this list. What separates this GE from the countertop-only picks is that it can be installed underneath a cabinet with an optional hanging kit sold separately, freeing up the entire counter surface. The 0.7-cubic-foot interior and 700-watt output match the BLACK+DECKER 0.7 Cu.Ft pick on size and power, and like that unit, it is built for daily reheating rather than heavy cooking.
Four convenience cook settings and one-touch express mode keep operation simple, and the keypad with digital display gives precise control over time and power. Manual and auto defrost round out the everyday functions. The stainless-steel interior is easy to wipe down, and the child lock can be switched off easily when not needed. GE’s clearance guidance applies: 3 inches on the sides and above, 1 inch at the rear, unobstructed bottom.
Several appreciate that it fits the same under-cabinet slot as the older Spacemaker line, which makes replacing an aging mounted unit straightforward. The recurring caveats: it is heavier than expected for its size, and the safety door-opening feature needs to be disabled via the manual if it becomes tiresome. Neither undercuts the core value — a genuine fit in a small kitchen that also handles under-cabinet mounting.
The case for it: dual-purpose design — countertop or under-cabinet with the optional hanging kit, at a 13-inch depth that fits snugly in a small kitchen.
Fair caveats: heavier than it looks, and the door safety lock needs to be deactivated manually if you find it annoying day to day.
Matches you if: you want the option to mount under a cabinet and free up counter space entirely, or you are replacing an older space-saver model.
Look past it if: you need higher wattage for regular cooking from frozen — 700 watts is the ceiling here.
9. TOSHIBA Flatbed Microwave Oven with Inverter Technology, 1.3 Cu.Ft, 1200W
The 1200-watt flatbed flagship — biggest interior here, no turntable to clean, tightest depth in the premium tier.
This is the most capable unit in the lineup on paper. 1200 watts of cooking power, a 1.3-cubic-foot interior — the largest capacity here — all while measuring just 14.6 inches deep by 20.4 inches wide by 12.5 inches tall. That combination means a genuinely shallow-depth fit without giving up interior room, which is rare at this size. The flatbed design also means no turntable to remove and wash, and no rotating plate to knock off-center.
Eleven power levels and 11 smart sensor auto menus handle pizza, pasta, vegetables, and more, with the smart sensor adjusting power based on detected moisture. Inverter technology delivers even cooking and quiet operation without the traditional magnetron cycling. A humidity sensor, an eco mode, and a mute function round out the feature set. There is no turntable at all — the microwave heats from an emitter system below the flat ceramic base — which owners describe as faster heating with much easier cleanup than traditional units.
Owner feedback repeatedly calls this the best microwave they have owned, with “so easy to clean” and “the most even heating microwave” as recurring themes. The loud beep is singled out as a plus by owners with hearing loss, and the fan running after cooking eliminates smells and condensation. The honest trade-off: reliability comes up as mixed in the reviews, and some reviewers point out units that will not turn on. Cook time must also be entered before the time, which trips some people up on first use. The door lock sits under the handle rather than a button, another small adjustment.
The flatbed advantage
- 1200W inverter power for fast, even heating across the whole cavity
- 1.3 cubic feet of interior in a 14.6-inch deep body
- No turntable — nothing to remove, nothing to misalign
- 11 sensor auto menus adjust to moisture as food reheats
Reading the fine print
- Some shoppers say failure to power on after use
- Cook time must be set before time entry, which confuses first-time users
- Door lock is under the handle rather than a dedicated button
Ideal for: anyone who wants the largest interior and highest wattage in a shallow-depth body, with the cleaner, turntable-free design as a bonus.
Approach with caution if: reliability is your top priority — a portion of owner reviews report power failures, so consider an extended warranty.
Understanding the Specs
Exterior Depth
This is the front-to-back measurement of the cabinet, and it is what decides whether the microwave fits your counter at all. A unit around fifteen inches deep is the balance for shallow counters — deep enough to hold a standard dinner plate on the inside, shallow enough to leave clearance at the front and back. When you measure your counter, account for the rear clearance the manufacturer requires (typically about an inch) and the side clearance for airflow.
Wattage
Wattage is the cooking power, measured in watts. Higher numbers reheat faster and push through frozen food more evenly. A 700-watt unit is fine for reheating and light cooking. A 900-watt or 1000-watt unit handles frozen entrées and leftovers with less waiting. A 1200-watt inverter unit delivers the fastest, most even heat in this group. Match the wattage to what you actually cook, not to the highest number on the shelf.

Final Thoughts: The Verdict
For most shallow-counter kitchens, the 15-inch deep microwave winner is the BLACK+DECKER Countertop Microwave Oven 0.9 Cu Ft because its 13.2-inch depth slides into the tightest counter slot here while still giving you 900 watts, six auto menus, and ten power levels — the crowd favorite across 700+ owners for its fit and compact size. If you want more interior room without stepping past the fifteen-inch threshold, the Chefman Countertop Microwave 1.1 Cu Ft is the pick, with its 1000 watts and 1.1 cubic feet. And if you want the largest capacity and a turntable-free interior, the TOSHIBA Flatbed Microwave 1.3 Cu.Ft is the one to reach for.
