9 Best Under Cabinet Microwave | Trim Kit Fit And 400 CFM Power

An under-counter microwave is the single most space-efficient way to reclaim counter real estate in a modern kitchen, but choosing the wrong one leads to a frustrating install with poor ventilation and a weak cook. The market is flooded with models that look identical on the spec sheet yet differ wildly in actual performance, mounting depth, and air movement capacity. Getting the right fit and power balance is the difference between a kitchen that feels open and one that feels cramped.

I’m Mohammad Maruf — the founder and writer behind AirfryerBite. I’ve spent years analyzing kitchen appliance hardware, from vent CFM ratings to interior cavity geometry, to help buyers cut through the noise on over-the-range installations.

After digging through dozens of specifications, installation guides, and real-world use cases, I’ve narrowed down the top contenders for the best under cabinet microwave based on cooking power, ventilation strength, and real-world fit for your cabinetry.

How To Choose The Best Under Cabinet Microwave

Picking an under cabinet microwave means balancing three factors: the physical dimensions of your cabinet cutout, the ventilation strength you need to clear cooking fumes, and the cooking power that matches how you actually reheat or defrost food. Ignoring any one of these can turn a promising purchase into a regretful installation.

Measure Your Cutout Width and Depth First

The vast majority of over-the-range microwaves are designed for a 30-inch wide opening, but you’ll also find 24-inch options for compact layouts. Depth is equally critical — a standard model extends about 15 to 16 inches from the wall, while low-profile units shave off several inches to clear shallow upper cabinets or hoods. Always measure your existing cutout width, height, and depth before browsing.

Ventilation CFM vs. Recirculation Mode

Ventilation power is measured in cubic feet per minute (CFM). A 300 CFM fan handles light steam and odors from typical stovetop cooking. A 400 CFM or higher fan is noticeably better at pulling smoke and grease from high-heat searing or frying. Some models default to recirculation (filtering air and venting it back into the kitchen) unless you install a duct kit. Decide whether you can duct to the outside or need recirculation, then match the CFM to your cooking habits.

Interior Capacity and Turntable Diameter

A 1.2 cu. ft. cavity is enough for a standard dinner plate and a 10-inch bowl, but a 1.7 cu. ft. or larger interior with a 12.4-inch turntable easily holds a full 12-inch pizza or a rotisserie chicken. Be aware that low-profile models often sacrifice interior height to shave overall depth, so check the turntable diameter and the vertical clearance if you routinely reheat tall mugs or casserole dishes.

In‑Depth Reviews

Best Overall

1. Midea MOR17BSA-SS 1.7 Cu.ft. Over The Range Microwave

1.7 cu.ft.300 CFM Vent

The Midea MOR17BSA-SS delivers a strong combination of a spacious 1.7 cu. ft. cavity and a 12.4-inch turntable that fits a full 12-inch pizza or a large rotisserie chicken without crowding. Its 1000W output and 10-level power settings give you precise control for everything from gentle defrosting to rapid reheating, while the 300 CFM two-speed fan effectively clears steam and odors from typical stovetop cooking. The stainless steel interior and exterior resist fingerprints and make cleanup straightforward.

The smart touch panel includes 18 auto-cook menus for popcorn, pizza, rice, potatoes, and softening cream cheese, which reduces guesswork for common tasks. The bright cooktop light provides clear visibility, and the overall build feels solid for a mid-range price tier. Installation requires a standard 30-inch wide cutout, and the depth of about 15.75 inches fits most standard upper cabinets without overhang.

While the venting is adequate for moderate cooking, heavy searing or frying may still benefit from a higher CFM unit. The touchscreen interface can feel slightly less responsive than physical buttons when your hands are wet or greasy. For most households needing a balanced performer, this Midea hits the sweet spot between capacity, power, and price.

Why it’s great

  • Large 1.7 cu.ft. cavity fits oversized dishes
  • 18 auto-cook menus simplify daily reheating
  • Stainless steel interior is easy to wipe clean

Good to know

  • Touch panel can be fussy with wet hands
  • 300 CFM fan is adequate but not the strongest

2. Farberware 1.7 Cu. Ft. Over-the-Range Microwave

1.7 cu.ft.Child Safety Lock

The Farberware 1.7 cu. ft. microwave is a straightforward over-the-range unit that prioritizes large capacity and essential features without unnecessary complexity. Its 1000W output and ten power levels provide reliable performance for daily tasks, while the dedicated Potato program and Veggies menu offer one-touch convenience for common sides. The white finish matches traditional kitchen decor and resists showing smudges.

A child safety lock adds peace of mind in households with young children, and the adjustable volume control lets you set the alert tone to low, normal, high, or completely off — a thoughtful detail for light sleepers. The LED timer and stovetop light are bright enough for practical use, and the efficient vent fan moves air adequately for moderate cooking. The included time and weight defrost settings allow precise thawing of meats.

The fan is not the most powerful at lower speeds, and the interior lacks the sensor cooking found on pricier models, so you may need to manually adjust times for some foods. The build feels a notch below premium units in terms of door hinge smoothness. Still, for the price, this Farberware delivers dependable function and a generous 1.7 cu. ft. cavity that handles family-sized portions well.

Why it’s great

  • Large 1.7 cu.ft. interior fits big casserole dishes
  • Child safety lock for secure kitchen use
  • Adjustable volume control for quiet operation

Good to know

  • No sensor cook or reheat modes
  • Vent fan performance is modest at low speed
Pro Grade

3. FRIGIDAIRE FFMV1846VS 30″ Over The Range Microwave

1.8 cu.ft.300 CFM Fan

The Frigidaire FFMV1846VS is a 30-inch wide over-the-range model with a 1.8 cu. ft. cavity, making it one of the largest capacity options available at this tier. Its 1000W cooking power and ten power levels give consistent reheating, while the 27 touch pad buttons provide dedicated access to functions like auto defrost, multi-stage cooking, and a kitchen timer. The two-speed fan delivers 105 or 300 CFM, allowing you to dial in the right ventilation level.

The stainless steel finish is durable and easy to clean, and the non-ducted venting type means it can be set up for recirculation without a separate kit, though the recirculating kit itself is sold separately if you need charcoal filters. The 15.75-inch depth is standard, fitting most over-the-range openings, and the 35-pound weight is manageable for a two-person install. The child lock adds an extra layer of safety.

The fan speed options are limited to just two, so you don’t get the fine control of a variable-speed blower. The interface uses physical buttons rather than a touchscreen, which some users prefer for tactile feedback but others find less modern. For a reliable, large-capacity appliance from a trusted brand with adequate venting, the Frigidaire FFMV1846VS is a solid mid-range contender.

Why it’s great

  • Spacious 1.8 cu.ft. interior for large cooking tasks
  • 300 CFM fan at high speed clears steam well
  • Physical buttons provide reliable tactile control

Good to know

  • Only two fan speeds available
  • Recirculation kit sold separately

4. Frigidaire Gallery Series GMBS3068BF 2.2 cu. ft. Built-in Microwave

2.2 cu.ft.1100W Input

The Frigidaire Gallery GMBS3068BF is a built-in model designed for a flush, integrated look rather than a traditional over-the-range mount, though it can be installed in a 27-inch or 30-inch opening with the separately sold trim kit. Its 2.2 cu. ft. capacity is enormous, comfortably accommodating multiple large dishes at once, and the 1100W input ensures fast, even heating. The sensor cooking technology automatically adjusts power and time based on steam emitted from the food, delivering consistently good results without manual tweaking.

The touchscreen control panel is modern and responsive, and the child safety lock is standard. The stainless steel finish and low-profile trim kit option give it a high-end, built-in appearance that blends seamlessly with cabinetry. The interior is spacious enough for a 13×9 baking dish or multiple plates stacked. The 24 7/16-inch width and 13 5/8-inch height are specific dimensions that require careful cutout planning.

The trim kit for the 27-inch or 30-inch opening is sold separately, adding to the total investment. It is also primarily designed as a built-in unit, not a traditional over-the-range model, so it lacks an integrated vent fan for stovetop ventilation — you will need a separate range hood. This unit excels for those doing a full kitchen renovation or custom cabinetry where a flush built-in look is the priority.

Why it’s great

  • Massive 2.2 cu.ft. cavity holds multiple dishes
  • Sensor cook adjusts time and power automatically
  • Flush built-in appearance with trim kit

Good to know

  • Trim kit sold separately for installation
  • No built-in vent fan — requires separate hood
Inverter Tech

5. Panasonic Microwave Oven NN-SN97JS 2.2 Cu. Ft. Cyclonic Inverter

2.2 cu.ft.1250W Cyclonic

The Panasonic NN-SN97JS sits at the top of the countertop microwave class with its 1250W Cyclonic Wave inverter technology, which delivers continuous power rather than the on-off cycling of traditional microwaves. This results in more even heating and better texture for delicate foods like fish or custard. The 2.2 cu. ft. cavity is paired with a 16.5-inch turntable, making it one of the largest single-plate interiors available.

The Inverter Turbo Defrost function speeds up thawing without cooking the edges, and the Genius Sensor automatically adjusts cooking times based on humidity levels. There are 20 preset menu items, a delay start timer, and a keep-warm feature that maintains food temperature without continuing to cook it. The stainless steel build is sturdy, and the interior is tall enough for a 10 15/16-inch tall dish.

This model is a countertop / built-in unit, not a traditional over-the-range microwave, so it does not include a vent fan for stovetop use. You would need a separate range hood if you want ventilation. The button-based control interface is functional but feels a bit dated compared to touchscreens. For those who prioritize cooking performance and even heating above all else, the Panasonic NN-SN97JS is a top-tier choice.

Why it’s great

  • Cyclonic Inverter for continuous, even power delivery
  • 16.5-inch turntable fits large platters
  • Inverter Turbo Defrost thaws quickly without cooking edges

6. Samsung ME11A7710DS/AA 1.1 Cu Ft Smart SLIM Over the Range Microwave

1.1 cu.ft.550 CFM Vent

The Samsung ME11A7710DS/AA stands out with its ultra-slim 10.75-inch height profile, making it ideal for kitchens with limited overhead clearance between the stovetop and lower cabinets. Despite its shallow depth, it packs a 550 CFM vent fan — the highest in this comparison — that aggressively pulls smoke and grease from heavy stovetop cooking. The 1.1 cu. ft. cavity is smaller than most competitors but still accommodates standard dinner plates and bowls.

Wi-Fi connectivity and voice control via smart assistants let you start, stop, or monitor the microwave remotely, and the LED light bar provides modern, bright cooktop illumination. Sensor cook and auto defrost functions simplify operation, and the ceramic enamel interior resists scratches and is easier to wipe clean than stainless steel. The fingerprint-resistant stainless steel finish keeps the exterior looking clean.

The smaller 1.1 cu. ft. capacity means you cannot fit a 12-inch pizza or a large casserole dish — the turntable is correspondingly smaller. The smart features require a stable 2.4 GHz Wi-Fi network, and some users find the app setup non-intuitive. If overhead clearance is tight and you need powerful ventilation, the Samsung slim model is a category leader, but the capacity trade-off is real.

Why it’s great

  • Ultra-slim 10.75-inch height saves overhead space
  • 550 CFM vent fan is the most powerful in this group
  • Wi-Fi and voice control for remote operation

Good to know

  • 1.1 cu.ft. capacity limits larger dish sizes
  • Smart app setup can be finicky
Multi-Function

7. BLACK+DECKER Over the Range Microwave Oven with Air Fryer EC942K6CE-SS

1.5 cu.ft.6-in-1 Modes

The BLACK+DECKER EC942K6CE-SS is a rare 6-in-1 over-the-range appliance that combines microwave, air fryer, convection, bake, roast, and combo grill functions into a single 1.5 cu. ft. unit. This versatility allows you to crisp french fries or chicken wings using the air fry mode, bake small casseroles, or roast vegetables — all while still functioning as a standard microwave. The 300 CFM two-speed fan removes stovetop steam effectively.

The sensor reheat mode maintains food moisture better than basic timed reheating, and the included microwave rack enhances airflow for convection and air frying tasks. The stainless steel interior is durable and easy to wipe down, and the touchscreen interface gives access to all six cooking modes cleanly. The 29.88-inch width fits standard 30-inch openings, and the 16.42-inch depth is typical for over-the-range units.

The 900W microwave output is lower than the 1000W-1250W of dedicated microwaves, which means standard microwave tasks may take slightly longer. The air fry and convection modes also require preheating and longer cook times than a dedicated countertop air fryer. For those who want to consolidate appliances and save counter space, this BLACK+DECKER is a compelling multi-tasker, but pure microwave performance is not its strongest suit.

Why it’s great

  • 6-in-1 functionality includes air fry and convection
  • Sensor reheat preserves food moisture
  • Versatile cooking modes reduce countertop clutter

Good to know

  • 900W microwave output is lower than dedicated units
  • Air fry mode requires longer preheat and cook times

8. Midea MMO12S3ASTZ Over the Range Microwave, 1.2 Cu.ft Slim with 400 CFM

1.2 cu.ft.400 CFM Vent

The Midea MMO12S3ASTZ is a slim over-the-range microwave that prioritizes overhead clearance with a 10.31-inch low-profile design, freeing up space for cabinets while still delivering 1000W of cooking power. Its 400 CFM vent fan is a significant step up from the 300 CFM standard, moving more air to clear steam, smoke, and odors from high-heat cooking. The 1.2 cu. ft. capacity is adequate for standard dishes but not oversized platters.

Smart home compatibility and voice control via the SmartHome app allow you to start, stop, and monitor cooking from your phone, with notifications when the cycle finishes. Sensor Cook and Sensor Reheat modes adjust power and time automatically based on humidity, removing guesswork from common tasks. The included grill feature adds browning capabilities, and the auto-cook menu covers essential one-touch presets.

The slim footprint naturally restricts the turntable size, so fitting a 13×9 dish may be tight. The smart app integration, while convenient, requires a reliable Wi-Fi connection and may not appeal to users who prefer purely manual control. For those who value overhead clearance and stronger ventilation in a compact form factor, the Midea MMO12S3ASTZ is a well-rounded choice.

Why it’s great

  • Slim 10.31-inch design for tight overhead clearance
  • 400 CFM vent fan provides strong air movement
  • Smart app control with voice assistant support

Good to know

  • 1.2 cu.ft. cavity limits large dish fit
  • Smart features need stable Wi-Fi connection
Low Profile

9. KoolMore 30 Inch Over-The-Range Low Profile Microwave KM-MLPOT-1SS

1.2 cu.ft.400 CFM Vent

The KoolMore KM-MLPOT-1SS is a dedicated low-profile over-the-range microwave with a 1.2 cu. ft. capacity and a 400 CFM motor, designed for kitchens where cabinet depth is minimal but strong ventilation is still required. Its 13.5-inch glass turntable is smaller than standard, but the unit’s slim 10.31-inch height creates valuable overhead breathing room. The stainless steel front and touch panel give it a clean, modern look.

Ten power levels, express cooking from 1-6 minutes, a 30-second quick-cook button, and weight-based defrost cover most daily needs. The controllable fan and light let you adjust venting and illumination independently. The turn-off turntable option is useful for heating oblong dishes that would otherwise hit the rotating glass. The child safety lock and kitchen timer add practical safety and convenience features.

The cavity is on the smaller side, so large casserole dishes or tall mugs may not fit easily. The lower power level presets require some experimentation for optimal results, as the sensor cooking found on pricier models is absent. For kitchens where a standard-depth microwave would protrude awkwardly, the KoolMore’s low-profile build and 400 CFM vent make it a strong specialist choice.

Why it’s great

  • Low-profile design saves overhead cabinet space
  • 400 CFM motor provides strong ventilation
  • Turn-off turntable option for oblong dishes

Good to know

  • 1.2 cu.ft. cavity limits larger dish capacity
  • No automatic sensor cook modes

FAQ

Can I install an over-the-range microwave if I do not have existing ductwork?
Yes, most over-the-range microwaves can operate in recirculation mode, which filters the air through charcoal filters and vents it back into the kitchen. You will need a recirculation kit (sold separately for some models) that includes the necessary charcoal filters. This setup is less effective at removing heat and moisture than ducted venting but is a practical solution for kitchens without external duct access.
What is the difference between a low-profile and a standard over-the-range microwave?
A low-profile over-the-range microwave typically stands about 10 to 11 inches tall, while a standard model is around 15 to 16 inches tall. The low-profile design provides more clearance between the microwave and the stovetop, which is useful for taller pots and pans or for kitchens with lower cabinets. The trade-off is that low-profile models usually have a smaller interior capacity and a shorter turntable, so they cannot fit large dishes or tall items.
How do I know if a 30-inch over-the-range microwave will fit my cabinet opening?
Measure the width of your existing cabinet opening or the space between your side cabinets. Most over-the-range microwaves are designed for a 30-inch wide opening, with the unit itself measuring roughly 29.8 to 29.9 inches wide. You should also measure the height from the stovetop to the bottom of the upper cabinet — most codes require at least 13 to 16 inches of clearance, but check your local building codes. Finally, measure the depth of your upper cabinet to ensure the microwave will not extend too far forward or interfere with cabinet doors.

Final Thoughts: The Verdict

For most users, the best under cabinet microwave winner is the Midea MOR17BSA-SS because it offers the strongest balance of large 1.7 cu. ft. capacity, 1000W cooking power, and a 300 CFM vent at a sensible mid-range price point. If you need the slim overhead profile and the most powerful ventilation available, grab the Samsung ME11A7710DS/AA with its 550 CFM fan. And for consolidating appliances into one unit with air fry and convection modes, nothing beats the BLACK+DECKER EC942K6CE-SS.
