A convection microwave combines standard microwave heating with a convection heating element and fan, letting you bake, roast, broil, and air fry in a single countertop appliance.
Standard microwaves can reheat leftovers and defrost meat but they’ll never brown a chicken thigh or crisp a pizza crust. A convection microwave adds a second cooking system — a heating element paired with a fan that circulates hot air around the cavity — so the same box that warms yesterday’s coffee can also roast vegetables, bake cookies, and air-fry frozen fries. For small kitchens, apartments, or anyone who wants one appliance instead of two, the trade-off is worth knowing: the cavity is smaller than a full oven, and the learning curve involves a few rule changes about cookware and temperature.
How a Convection Microwave Works
The appliance runs three cooking modes, each serving a different purpose. Standard microwave mode uses electromagnetic waves that excite water molecules in food — fast, no browning. Convection mode activates a heating element and fan that blow hot air around the cavity, producing the dry, even heat needed for browning and crisping. Some models also support combination mode, where microwave energy and convection heat cycle together for faster cooking that still browns the exterior.
In convection mode, the internal fan runs continuously in one direction and does not cycle off with temperature changes, so the hot air stays moving the whole time. The turntable rotates during convection cooking, which helps distribute heat evenly around the food.

What You Can Cook With It
Convection microwaves handle everything a regular microwave does — reheat soup, pop popcorn, melt butter — plus oven-style tasks that require dry heat. You can bake sheet-pan vegetables, roast chicken thighs, cook a small lasagna, make crispy bacon, or air fry frozen foods. The convection fan produces browning and texture that a standard microwave cannot deliver.
The big limitation is size. Convection cavities are smaller than a standard oven. A whole turkey won’t fit, and you cannot cook for a crowd in one batch. For everyday meals, small batches, or single servings, the convection microwave performs well. For holiday dinners, keep your standard oven as a backup.
Temperature and Time Adjustments (Critical)
If you adapt a conventional oven recipe for a convection microwave, you must reduce both temperature and time. GE’s support documentation advises lowering the recipe’s oven temperature by 25–50°F (roughly 20 percent) and cutting the cooking time by about 20 percent. The moving hot air transfers heat faster than a still oven, so food cooks more quickly. Skipping this adjustment is the most common mistake with convection cooking and leads to burnt exteriors before the center is done.
Cookware Rules That Matter
The microwave and convection modes have different rules about what goes inside, and confusing them can damage the appliance.
| Item | Convection mode | Standard microwave or combination mode |
|---|---|---|
| Metal baking pan | Allowed | Never — risk of arcing |
| Aluminum foil | Allowed (keep away from walls and vents) | Never |
| Oven rack (provided with unit) | Allowed | Never |
| Standard microwave-safe plastic | Not safe — heat may exceed 400°F | Allowed |
| Heat-resistant plastic (convection-oven rated) | Allowed | Allowed |
| Glass or ceramic bakeware | Allowed | Allowed (microwave-safe only for microwave mode) |
Use the oven racks that came with your unit — they support airflow underneath the food. Choose bakeware with low sides; deep casserole dishes block the fan’s hot air circulation and cause uneven cooking.
How To Cook With a Convection Microwave
Using a convection microwave is straightforward once you know the sequence for each mode.
- For convection cooking: Press the Convection or Bake button, set the temperature, and hit Start. The unit preheats and signals when it’s ready. Place food in the oven on the provided rack using low-sided bakeware.
- For combination cooking (on supported models): Select the Combination or Convection Roast option. The microwave energy and heating element cycle together. Food cooks faster than pure convection while still developing a browned exterior.
- For standard microwave use: Operate exactly like a regular microwave. Do not place metal or foil inside during standard microwave mode.
Who Should Buy One
A convection microwave fits best when you have limited counter space and want the versatility of an oven without dedicating the room. It works especially well in apartments, RVs, small homes, dorm rooms, or as a secondary cooking appliance in a kitchen where the main oven is used for big meals. The price premium over a standard microwave — roughly $100 to $400 more — buys two cooking systems in one footprint.
If you already have a full-size oven and rarely bake small batches, a regular microwave may be all you need. But if you find yourself avoiding the oven because heating it up for one sheet pan of vegetables feels wasteful, a convection microwave changes that calculation. The preheat time is shorter, the energy use is lower, and the results are comparable.

Common Mistakes and How To Avoid Them
Three errors account for most of the negative reviews from first-time convection microwave owners:
- Using metal in the wrong mode. Metal pans and foil are safe in convection mode only. In standard microwave or combination mode, metal can arc and damage the unit. If you switch between modes during a single recipe, remove all metal before switching to microwave.
- Using high-sided bakeware. The hot air needs to circulate around the food. A deep casserole dish blocks that airflow. Use low-sided baking sheets or shallow pans.
- Skipping the preheat. Convection mode needs the cavity to reach the set temperature before food goes in. Without preheating, cooking times become unpredictable and browning suffers.
Safety and Long-Term Care
Standard microwave-safe plastic containers can warp or melt at convection temperatures that reach 400°F and above. Use only heat-resistant plastic rated for conventional oven use. Keep foil away from the air vents at the back and sides of the cavity — blocked vents can cause the unit to overheat. The convection fan and heating element add complexity compared to a simple microwave, so cleaning the cavity regularly (especially baked-on food residue) helps the appliance last longer.
FAQs
Can a convection microwave replace a standard oven?
Not entirely. It handles small to medium batches well — roasted vegetables, chicken pieces, frozen pizzas, baked potatoes — but the smaller cavity cannot accommodate a whole turkey, large sheet pans, or multiple trays at once. It works best as a supplement to a standard oven or as a primary oven in a small living space.
Do I need special cookware for a convection microwave?
You need oven-safe materials — glass, ceramic, metal, or heat-resistant plastic — when using convection mode. Standard microwave-safe plastic may melt at convection temperatures. The included metal rack is designed for the convection setting. Always verify that a dish is safe for the specific mode you plan to use.
Is a convection microwave more expensive than a regular microwave?
Yes. Standard microwaves start around $60–100, while convection models typically range from $160 to over $1,000 depending on capacity, wattage, and features like air frying or smart controls. The extra cost buys the convection heating element and fan plus additional cooking modes.
Can I air fry in a convection microwave?
Yes, many convection microwaves include an air fry setting or an air fry basket accessory. The convection fan and high heat produce the same crispy results as a dedicated air fryer, though the cavity may be smaller than a full-size air fryer. Some models, like Contoure’s Smart Air Fry line, are designed specifically for this function.
Does a convection microwave use more electricity than a regular microwave?
It uses more power when the convection heating element is running — typically up to 1,400 watts versus 1,000 watts for microwave-only operation. But it uses less energy than heating a full-size conventional oven for small meals because the smaller cavity reaches temperature faster and retains heat more efficiently.
