Finding a microwave that fits a tight countertop without sacrificing heating power or preset convenience is the real challenge in a small kitchen. Most compact models squeeze wattage and interior capacity into a smaller footprint, but the best options also deliver even heating, intuitive controls, and essential safety features like a child lock and mute function.
I’m Mohammad — the founder and writer behind ProteinJug. I analyze hundreds of microwave oven specifications each year, comparing output wattage, cavity dimensions, turntable size, and preset accuracy so you don’t have to sort through the noise.
After reviewing the current crop of under-1.0-cubic-foot countertop microwaves, I condensed the field down to the seven most reliable performers. Use this guide to find the best small microwave oven for your space, cooking habits, and budget.
How To Choose The Best Small Microwave Oven
A small microwave oven must balance three competing priorities: physical footprint, interior capacity, and heating power. A unit that is too shallow won’t fit a dinner plate; a unit with low wattage will leave cold spots in leftovers. Use this buying framework to match the right combination of specs to your daily cooking patterns.
Wattage and Power Delivery
Compact microwaves typically offer 700W or 900W output. The 700W models heat more slowly and may struggle with larger frozen meals, but they draw less power and are quieter in operation. The 900W units, like the TOSHIBA and Kenmore reviewed here, bring food to temperature faster and defrost more evenly. If you regularly reheat dense items like casseroles or thaw frozen proteins, aim for the 900W tier.
Turntable Diameter vs. Interior Height
The glass turntable’s diameter is the real constraint on what fits inside. A 9.5-inch turntable fits standard lunch plates but not a 10-inch dinner plate. The 10.6-inch turntable found in the Smad and TOSHIBA models accommodates larger bowls and plates without the edges scraping the interior walls. Always check both turntable diameter *and* interior height if you plan to heat tall mugs or nesting bowls.
Controls, Presets, and Mute Function
Touch-button panels with dedicated presets (popcorn, pizza, potato, beverage) reduce guesswork, but the layout logic varies widely. Some models require pressing “Cook” then a number key for simple heating — a frustrating extra step. The mute button is a category-specific gem: it silences the end-of-cycle beep, which is a lifesaver in open-plan apartments, dorm rooms, or if you heat food while others sleep.

In-Depth Reviews
1. COMFEE’ EM720CPL-PM
The COMFEE’ EM720CPL-PM punches above its 700W rating thanks to a surprisingly large 10.6-inch glass turntable and a stainless steel cavity that minimizes hotspot formation. Multiple customer reports confirm that it heats beverages and leftovers evenly, and the two-stage child lock is one of the simplest to activate and deactivate in this class.
The mute function is a standout for this price tier — hold the sound button for three seconds and the microwave operates silently, which is rare on sub- countertop units. The ECO mode cuts standby power by half, making it a solid choice for energy-conscious households or dorm rooms where the microwave stays plugged in constantly.
Build quality is better than its price suggests. The door seals tightly, the button pad registers presses without extra force, and the interior light stays bright throughout the cooking cycle. The only real compromise is the 700W maximum output, which adds about 20-30 seconds to typical heating times compared to 900W models.
Why it’s great
- Large 10.6″ turntable in a 0.7 cu ft shell
- Mute button for silent operation
- ECO mode reduces standby power 50%
Good to know
- 700W output adds 20-30 seconds vs 900W units
- White exterior shows stains more than stainless steel
2. Smad 0.9 cu ft Countertop Microwave
The Smad 0.9 cu ft microwave delivers 900W of heating power in a footprint only slightly larger than a typical 0.7 cu ft unit. Its interior comfortably accommodates a 12-inch frozen pizza or a 2.5-pound whole chicken, making it one of the most space-efficient options in the mid-range segment.
Six one-touch presets cover popcorn, potato, pizza, frozen veggie, beverage, and dinner plate — each with a tested power-and-time curve that produces consistent results. The multi-stage cooking feature lets you defrost and then cook without resetting the program, which is a genuine time-saver when preparing meals from frozen.
The lift-to-open safety lock design requires pressing upward on the door handle to release the latch, an extra step some users find reassuring and others find slightly fussy. The interior is coated with an easy-clean surface that resists splatter buildup, though it is an enamel coating rather than full stainless steel.
Why it’s great
- 900W output for faster reheating and defrosting
- Fits a 12-inch pizza inside a compact shell
- Multi-stage cooking combines defrost + cook
Good to know
- Enamel interior not as durable as stainless steel
- Lift-to-open latch may feel awkward at first
3. Chefman Compact 0.7 cu ft Microwave
The Chefman 0.7 cu ft microwave is among the shallowest models on this list, with a depth under 13 inches. It fits neatly on narrow countertops, small kitchen carts, and dorm-style shelving where depth clearance is as critical as width. The 700W output is adequate for single-serving reheating and quick snacks.
The mute button is conveniently labeled and silences all beeps — useful for office break rooms or late-night kitchen use. Three dedicated presets (popcorn, beverage, leftovers) cover the most common use cases without overwhelming the control panel with rarely-used programs.
One notable trade-off is the 9.5-inch turntable, which cannot hold dinner plates larger than standard salad plates. The door latch mechanism is a pull-up handle rather than a push-button release, which some users found less intuitive initially. The stainless steel body resists fingerprints well and wipes clean easily.
Why it’s great
- Ultra-shallow 12.93″ depth fits tight spaces
- Clear mute button for silent operation
- Durable stainless steel exterior resists smudges
Good to know
- 9.5″ turntable limits plate size
- 700W adds time for dense frozen meals
4. TOSHIBA ML-EM09PA(SS)
TOSHIBA’s ML-EM09PA(SS) packs 900W into a stainless steel body with a bright LED-lit cavity that makes monitoring food easy. The 10.6-inch removable turntable rotates smoothly and stops at a consistent position after each cycle, which reduces the annoyance of awkwardly angled plates.
Six preset menus (popcorn, potato, pizza, frozen dinner, beverage, reheat) each use specific power ramps that heat more evenly than generalized presets. The defrost-by-weight function is more accurate than defrost-by-time for frozen meats, and the kitchen timer doubles as a countdown clock when not cooking.
The control panel uses a touch keypad rather than mechanical buttons, which feels more premium but requires a deliberate press. Some users reported the buttons beep on every press; this can be silenced via the mute function. The unit is also slightly heavier than comparable 0.9 cu ft models, so plan a stable countertop spot.
Why it’s great
- 900W with even heating and accurate defrost-by-weight
- LED interior lighting for clear visibility
- Touch keypad with mute option
Good to know
- Keypad requires firm presses
- Heavier than average 0.9 cu ft unit
5. Kenmore 0.9 cu ft Countertop Microwave
The Kenmore 900W microwave is designed to visually match other Kenmore kitchen appliances, sharing the same brushed stainless steel finish and clean button layout. It measures 19 inches wide, making it one of the larger-footprint options in the 0.9 cu ft category, but the interior is proportionally spacious.
Six auto-cook presets cover popcorn, potato, pizza, frozen dinner, beverage, and reheat. The defrost feature lets you choose between time-based and weight-based thawing. The control panel includes a dedicated kitchen timer and a clock display that can be toggled off if you prefer a dark standby screen.
The child lock is active by default on some units and requires pressing the unlock button before every cooking cycle, which users either appreciate or find slightly tiresome. The noise level is lower than average for a 900W microwave, making it a better fit for open-plan living where kitchen sounds carry.
Why it’s great
- Matches Kenmore appliance aesthetic
- Low noise operation for open kitchens
- Clock display can be turned off
Good to know
- 19″ width requires generous counter space
- Child lock stays active between uses
6. BLACK+DECKER 0.9 cu ft Microwave
BLACK+DECKER’s 0.9 cu ft microwave stands out for its memory function, which stores your last-used power level and cook time for quick recall — a feature usually found on larger, pricier units. Ten adjustable power settings range from a low warm melt to full 900W blast, giving you fine-grained control over delicate foods like leftovers or melting chocolate.
Six auto menus (popcorn, potato, pizza, frozen vegetables, beverage, dinner plate) are pre-programmed with power curves that match typical serving sizes. The two-step child lock meets current safety standards and can be deactivated permanently if you don’t need it. The digital display is bright and easy to read from across the counter.
The interior is plastic rather than stainless steel, which is a downgrade for durability and cleaning ease compared to the TOSHIBA or Kenmore. The unit width is 18.6 inches, so measure your available space carefully. The memory function alone may justify the upgrade for users who reheat the same items repeatedly.
Why it’s great
- Memory function stores last cook settings
- 10 power levels for precise control
- Bright, readable digital display
Good to know
- Interior is plastic, not stainless steel
- 18.6″ width needs generous counter space
7. GE 0.9 cu ft Countertop Microwave
The stainless steel and black glass construction feels solid, and the turntable rotates smoothly for even cooking throughout the cycle.
The two-step child lock is standard, and the kitchen timer function operates independently from the cooking controls. The mute option silences the beeps at the end of the cycle, and the clock display can be turned off to reduce light pollution in a bedroom or media room setup.
Some users found the control logic unintuitive for simple tasks: heating for 30 seconds requires pressing “Cook” then entering time, rather than a direct “Add 30 Seconds” button. The turntable also stops in a slightly different position each cycle rather than returning to the original orientation, which some find visually distracting.
Why it’s great
- 900W with 7 auto-cooking presets
- Independent kitchen timer function
- Stainless steel and black glass build feels premium
Good to know
- Controls not intuitive for quick heating
- Turntable stops in random position

Final Thoughts: The Verdict
For most users, the best small microwave oven winner is the COMFEE’ EM720CPL-PM because it packs a 10.6-inch turntable, mute button, and ECO mode into a 0.7 cu ft shell at a remarkably accessible price point. If you need faster 900W heating and a larger interior to fit dinner plates, grab the Smad 0.9 cu ft for its balanced mix of power and footprint. And for premium build quality with 6 auto menus and a bright LED cavity, nothing beats the TOSHIBA ML-EM09PA(SS).
