A built-in microwave is the clean way to get a microwave off the counter and into your cabinetry, whether that means a front-loading unit framed by a trim kit or a drawer that slides out under the worktop. The trade-off is fit: unlike a countertop model you can set down anywhere, a built-in has to match a specific cabinet cutout, and many need a trim kit sized to the opening. This guide gathers five to seven built-in and drawer-style microwaves and sorts them by the job they do best, from a roomy flush built-in to a compact drawer for a tight kitchen.
Our top picks: built-in microwaves
Our overall pick is the Frigidaire Gallery GMBS3068BF, a 2.2 cu ft front-loading built-in that gives you a large interior and a recognized brand name, provided you add the separately sold trim kit. From there we break the field down by need: the Summit SMBI24 for shoppers who want the trim kit included, the AAOBOSI 24 inch for convection and air fry, the Sharp SMD2470ASY for a true microwave drawer, the ThermoMate drawer for a compact kitchen, and the Panasonic NN-SN97JS for flexible countertop or built-in use.
How we evaluated these products
These are editorial picks based on current Amazon listings, not lab results. We did not install, run, or measure these units, so every capacity and wattage figure here is a listing claim from the manufacturer, and you should verify the exact specification on the product page before you buy. We focused on the details that matter most for a built-in: the stated width, whether the unit is a front-loading built-in or a drawer, the listed capacity, whether a trim kit is included or sold separately, and whether convection is offered. We also weighed how clearly each listing described its install requirements, because fit is the single biggest reason a built-in purchase goes wrong.
The picks in detail
Frigidaire Gallery GMBS3068BF, our top pick
The Frigidaire Gallery GMBS3068BF leads on interior room, with a 2.2 cu ft listed capacity that handles larger plates and dishes. It is designed to sit flush once paired with the matching trim kit, which Frigidaire sells separately, so plan for that extra purchase and measure your opening first. For a roomy, brand-name built-in with a clean finished look, it is the one we would start with.
Summit SMBI24, best with trim kit
The Summit SMBI24 removes a common headache by shipping with its trim kit, so you are not matching a microwave to a separate frame. It is a 24 inch stainless model that fits a standard opening. The listing does not state capacity, so confirm that figure if interior volume is a priority for you.
AAOBOSI 24 inch, best convection
The AAOBOSI 24 inch is the convection choice, with a listed convection and air fry combo on top of microwave cooking. That versatility lets it brown and crisp, not just reheat. Its 1.6 cu ft listed capacity is smaller than the 2.2 cu ft units, which is the trade for the extra cooking modes, so confirm the cutout and any clearance needs.
Sharp SMD2470ASY, best drawer
The Sharp SMD2470ASY is a microwave drawer that pulls out rather than swinging open, which makes loading tall containers easy and suits islands and under-counter spots. Its 1.2 cu ft listed capacity is smaller than front-loading units, the usual trade for drawer convenience. Because it mounts under a counter, plan the opening, support, and electrical supply with care.
ThermoMate 24 inch drawer, best compact
The ThermoMate 24 inch drawer is the compact pick, with a 1.2 cu ft listed capacity that tucks under a counter and keeps the worktop clear. Its listing states 1000 watts, 11 power levels, touch controls, presets, and sensor cooking. It is a less familiar brand than Sharp, so weigh that against the small footprint and the listed feature set.
Panasonic NN-SN97JS, best value
The Panasonic NN-SN97JS is the flexible option because its listing covers both countertop and built-in use. Run it on the counter now and build it in later with a trim kit. It lists a 2.2 cu ft capacity, 1250 watts, inverter technology, and a Genius Sensor, which makes it a practical pick when you are not ready to commit to a permanent cutout.
How to choose a built-in microwave
Built-in vs drawer vs convertible countertop
There are three broad formats here. A front-loading built-in, like the Frigidaire Gallery or Summit, sits in a wall cabinet and usually needs a trim kit to look finished. A drawer, like the Sharp or ThermoMate, pulls out from under a counter or inside an island and does not use a trim kit, which is handy where there is no wall cabinet. A convertible countertop unit, like the Panasonic, can start on the counter and move into a cabinet later with a kit, which is the most forgiving if your plans are not final.
Cabinet cutout and trim kits
Fit is everything with a built-in. Measure the cabinet opening precisely and match it to the listed width, commonly 24 inch on the models here. If the unit uses a trim kit, make sure the kit is the correct one for that exact model and opening, since the wrong size leaves gaps or will not seat at all. Where a trim kit is sold separately, factor that second item into your planning.
Capacity and interior space
Listed capacity ranges from about 1.2 cu ft on the drawers to 2.2 cu ft on the larger front-loading units. More capacity means more room for big plates and casserole dishes, while a drawer trades some of that volume for easy access and a clear counter. Decide which matters more in your kitchen before you fix on a format.
Convection and cooking modes
Most microwaves only reheat and defrost. A convection model like the AAOBOSI adds a fan and heating element so it can bake, roast, and in this case air fry. If you want one appliance to do more than warm food, convection is worth the smaller interior and the slightly different install clearances it may require.
Controls and sensor cooking
Look at how each unit is operated. Touch controls, automatic presets, and sensor cooking, which adjusts time based on steam, all show up on these listings and make daily use simpler. The Panasonic lists a Genius Sensor and inverter technology, while the ThermoMate lists sensor cooking with 11 power levels, as examples of what to compare.
Electrical and professional install
A built-in or drawer ties into your cabinetry and your wiring, so the electrical supply at the install point has to match what the unit needs. Confirm the circuit and outlet requirements on the listing or in the manual, and because a flush, safe fit depends on getting the opening, support, and connections right, professional installation is recommended.
A note on fitment and installation
Built-in microwaves need a correctly sized cabinet cutout, and many front-loading models need a trim kit to finish the look, while others are drawer-style and install under a counter. Before you buy, confirm the cutout dimensions, the trim-kit compatibility, and the electrical requirements for your chosen model, and follow the maker's install guide. Professional installation is recommended. Remember that the capacity and wattage figures in this guide are listing claims from the manufacturer, not measurements we took.
The bottom line
For most kitchens, the Frigidaire Gallery GMBS3068BF is the built-in we would pick first for its roomy 2.2 cu ft listed capacity and clean built-in design, with the trim kit planned in. Choose the Summit SMBI24 if you want that kit included, the AAOBOSI 24 inch for convection, the Sharp SMD2470ASY or the compact ThermoMate for a drawer, and the Panasonic NN-SN97JS when you want to keep your options open. Whichever you choose, measure twice, match the trim kit and the cutout, and check the electrical needs before you order.
