A convection microwave combines quick microwave heating with oven-style baking and browning. It suits cooks who want to reheat lunch and make smaller baked or roasted meals in the same countertop appliance.

The extra function earns its space when you use it regularly. If most meals involve warming soup or leftovers, a standard microwave is usually the simpler choice.

How does a convection microwave work?

A convection microwave has 2 heating systems: microwave energy heats food, while an element and fan heat and circulate the air around it. Depending on the model, you can select either system or a program that uses both.

Microwave energy interacts with water and other molecules in food to produce heat. It's useful for reheating and defrosting, but microwave-only cooking doesn't create the dry surface heat needed for much browning.

Convection mode works like a small fan oven. It can brown vegetables, bake smaller portions, and crisp surfaces that would stay soft under microwave heat alone.

Combination cooking adds microwave heating to an oven-style program. Use the appliance's recipe guidance because ordinary oven times won't necessarily suit a cycle that uses both systems.

What can you cook in a convection microwave?

A convection microwave can reheat, defrost, bake, and roast, with air frying or broiling available on some models. Match the mode to the result: moist reheating, baked centers, crisp edges, or a browned top.

Use microwave mode for soup, rice, and similar leftovers. Choose convection for small batches of baked goods or roasted vegetables, leaving space around the food for airflow.

Capacity is only part of the fit. A dish must clear the walls, rotate when required, and fit beneath any rack or heating element; our guide to countertop microwave sizes and dimensions explains what to measure.

Which convection microwave features help with everyday cooking?

Choose cooking modes you'll use each week before counting presets. Broiling is useful for a browned finish, while dedicated racks and pans support specific cooking modes.

The GE 4-in-1 Microwave Air Fryer combines microwave, air fry, convection, and broil functions. It includes a stainless steel crisper pan, a tall broiling rack, and a short convection rack.

GE suits cooks who want to bake small portions and finish dishes under a broiler. Its 1.0 cubic foot cavity and 1,050-watt microwave power make it worth considering for everyday meals, but skip it if you only need reheating.

Allow 3 inches at each side and above, plus 1 inch behind it, and keep the bottom unobstructed. Compare alternatives in our small countertop microwave guide if that full space won't fit.

Is a convection microwave different from an air fryer microwave?

A convection microwave doesn't automatically include air frying. Check for a dedicated air fry mode if crisping fries, breaded foods, or similar snacks is a regular goal.

Both modes use moving hot air, but the settings and accessories differ. Spread food out rather than stacking it, since crowded surfaces trap moisture and limit browning.

The Sharp 3-in-1 Convection Air Fry Microwave offers microwave, convection, and air fry modes. Its multi-stage program can run up to 3 functions in one operation, including defrosting, cooking, and crisping.

Sharp suits smaller portions and cooks who want linked cooking stages. It has a 0.9 cubic foot cavity, a 10.6-inch turntable, and a dishwasher-safe air fry basket; skip it if your usual cookware needs more room.

Which features matter before you choose one?

Prioritize dish fit, usable counter space, and cooking controls over the longest feature list. Start with your largest everyday dish and the meals you actually plan to make.

Check usable space before wattage

Measure width, depth, height, ventilation gaps, and room to open the door. Inside, check whether your pan fits with the required rack installed, rather than relying only on cubic feet.

Compare microwave cooking output with microwave cooking output. Input power describes electricity drawn by the appliance, so it isn't interchangeable with cooking output; see how many watts a countertop microwave needs for help.

Choose controls that suit your cooking habits

Choose guided settings for repeat tasks and accessible manual controls for recipes you adjust yourself. Confirm that the oven mode supports the temperatures your usual recipes require.

The Breville Combi Wave 3-in-1 includes an inverter microwave, convection oven, and air fryer. Fast Combi, Cook from Frozen, and shortcuts for tasks such as softening butter give frequent users more ways to handle routine cooking.

Breville suits cooks who will use its combination programs and shortcuts, with a Combi Crisp Pan and trivet included. Skip it if you want basic reheating controls or have a shallow counter: its body measures 20.08 inches deep before ventilation space.

The Panasonic HomeChef 4-in-1 Combo suits cooks who want step-by-step recipe guidance through the Panasonic Kitchen+ app. It combines microwave, broiler, air fry, and convection modes, with sensor reheat also available.

Its 1.2 cubic foot cavity and 14.2-inch turntable offer more room than Sharp for wider dishes. Skip it if app guidance has little value to you and your current dishes already fit a smaller appliance.

Panasonic is 22 inches wide and 17.7 inches deep. Confirm height before planning a tight installation, since Panasonic gives both 13.4 and 13.5 inches; built-in use requires the optional NN-TK81KCS trim kit and its installation instructions.

How should you set up a convection microwave?

Set it on a stable surface with the required ventilation space before using any heating mode. Keep vents clear and follow the manual's electrical and placement instructions.

Don't treat a countertop model as a built-in appliance just because it fits a shelf. Read whether a countertop microwave can go in a cabinet before enclosing it.

Remove packaging and follow the first-use instructions. Identify each rack, basket, and tray, then note which modes allow it so you won't have to guess while handling hot cookware.

Leave a heat-safe landing spot nearby for dishes. Convection cooking heats pans and accessories, so use oven mitts rather than expecting them to stay cool like some microwave-only containers.

How do you use a convection microwave without common mistakes?

Start with the correct mode and cookware, then follow the manual's preheating and rack guidance. A microwave-safe container isn't necessarily oven-safe, and an oven-safe metal pan isn't automatically suitable for combination cooking.

For microwave-only use, vent covers as directed, stir foods when practical, and allow standing time when instructed. Don't assume a steaming surface means a thick portion is hot throughout.

For convection baking, preheat when the recipe or manual calls for it. Leave space around the pan and avoid packing the cavity so tightly that air can't circulate.

When adapting an oven recipe, check progress early and note any changes for next time. Don't apply one time reduction to every dish, especially when switching between convection-only and combination programs.

Follow instructions for raw meat and poultry, and use a food thermometer to check doneness. Browning alone doesn't show whether the center has finished cooking.

Our guide to how to use a convection microwave covers mode selection and cookware in more detail.

How do you keep it clean between cooking modes?

Clean splashes and grease after the appliance cools, using the method its manual permits. Residue from reheating can bake onto the cavity during a later convection cycle.

Wash removable accessories as directed and let them dry before putting them away. Dishwasher approval for one basket doesn't mean every rack, tray, or turntable can go in the dishwasher.

Avoid abrasive pads on interior surfaces, and keep grease away from vents. Wipe the door edges and sealing surfaces gently, without disturbing covers or fittings inside the cavity.

Which convection microwave should you choose?

Choose a convection microwave around your portion size and cooking routine. For smaller dishes and linked defrost-to-crisp stages, choose Sharp; for small meals that also need broiling, consider GE.

Choose Breville if combination programs and cooking shortcuts will be part of your week. Pick Panasonic if wider dish space and app-guided recipes are useful enough to justify its counter space.

If you mainly warm drinks and leftovers, use our countertop microwave buying guide to choose a simpler model. If crisping is a regular need, compare the best microwave air fryer combos after measuring your cookware and installation space.

Frequently asked questions

What does convection mean in a microwave?

Convection means a heating element and fan circulate hot air around food. This lets the appliance bake and brown food, while its microwave mode handles quick heating and defrosting.

Some models also offer combination programs that use both heat sources during the same cooking cycle.

Can a convection microwave replace an oven?

A convection microwave can replace an oven for smaller cooking jobs, including baking small portions and roasting vegetables. It won't suit every pan or batch size.

Check usable space with the required rack installed, your cookware dimensions, and the temperature settings your recipes need before giving up a separate oven.

Is a convection microwave the same as an air fryer microwave?

No, convection and air fry are different settings, though both use moving hot air. A convection microwave can bake and brown without having a dedicated air fry mode.

If crisping fries or breaded foods is a priority, choose a model with an air fry setting and its required basket or pan.

What cookware can you use in a convection microwave?

Use cookware approved for the selected mode in your appliance manual. Microwave-only cooking needs microwave-safe dishes, while convection-only cooking needs oven-safe cookware.

Combination cooking requires cookware suitable for both kinds of heat.

Use metal racks, pans, and baskets only in the modes and positions that the manual allows.
