Quick Comparison
Both appliances have a place in your kitchen. Here is how they stack up across the categories that matter most.
| Feature | Air Fryer | Microwave |
|---|---|---|
| Cooking method | Hot air circulation | Electromagnetic waves |
| Texture | Crispy outside, juicy inside | Soft, sometimes soggy |
| Speed | Fast (8–25 min) | Fastest (1–5 min) |
| Reheating leftovers | Restores crispiness | Quick but often soggy |
| Frozen foods | Excellent — crispy results | Works but soft |
| Energy use | Moderate | Low |
| Best for | Cooking & crisping | Reheating liquids & soft foods |
| Worst for | Liquids & soups | Anything that should be crispy |
When to Use Your Air Fryer
If the end goal is crispy, golden, or well-browned food, the air fryer is the clear winner. Rapid hot-air circulation mimics deep frying without the oil, giving you that satisfying crunch on the outside while keeping the inside moist.
Anything You Want Crispy
From homemade french fries to breaded chicken cutlets, the air fryer delivers a crunch that a microwave simply cannot replicate. The circulating air removes surface moisture quickly, creating a golden exterior in minutes.
Reheating Pizza, Fries, and Fried Foods
Leftover pizza reheated in an air fryer tastes almost as good as fresh delivery. The crust gets crispy again, the cheese melts evenly, and the toppings warm through. The same goes for fries, onion rings, and any previously fried food. Two to four minutes at 350–375°F is all it takes.
Cooking Proteins
Chicken breasts, salmon fillets, pork chops, and steaks all benefit from the Maillard reaction that an air fryer encourages. You get a seared exterior with a juicy center — something a microwave cannot achieve.
Frozen Snacks
Frozen mozzarella sticks, tater tots, egg rolls, and chicken nuggets come out just as good as (or better than) oven-baked, in roughly half the time. No preheating a full oven — just load the basket and go.
When to Use Your Microwave
The microwave excels at speed and convenience. When texture is not the priority — or when you are working with liquids and soft foods — the microwave is the smarter choice.
Reheating Soups and Liquids
Soup, stew, broth, and sauces heat evenly and quickly in a microwave. An air fryer is not designed for liquids, and attempting to reheat soup in one would make a mess and produce poor results.
Steaming Vegetables
A damp paper towel over a bowl of broccoli or green beans in the microwave produces perfectly steamed vegetables in two to three minutes. This method preserves nutrients better than most other cooking techniques.
Warming Beverages
Need to reheat your coffee or warm up some milk? The microwave does this in under a minute with zero cleanup. There is no air-fryer equivalent for this task.
Defrosting Quickly
Most microwaves have a defrost setting that thaws meat, bread, or other frozen items in minutes. While you can cook from frozen in an air fryer, the microwave is faster when you just need to thaw something before cooking it another way.
Heating Up Rice and Pasta
Leftover rice and pasta reheat beautifully in the microwave. A splash of water and a covered bowl bring them back to life in one to two minutes, soft and ready to eat. An air fryer would dry them out.
The Reheat Test
Reheating leftovers is one of the most common uses for both appliances. Here is how they compare on three popular leftover foods.
Leftover Pizza
Air fryer: 3–4 minutes at 350°F. The crust turns crispy, the cheese re-melts, and the slice tastes nearly as good as fresh. This is the gold standard for reheated pizza.
Microwave: 30–60 seconds. It is fast, but the crust becomes chewy and soft, and the bottom can turn rubbery. Fine when you are in a rush, but the texture suffers.
Winner: Air fryer, by a wide margin.
Leftover Fries
Air fryer: 3–5 minutes at 375°F. Fries come back to life with a crisp exterior and a fluffy interior. Shake the basket once halfway through for even results.
Microwave: 1–2 minutes. The fries turn limp and soggy almost immediately. Microwaved fries are widely regarded as one of the worst reheating experiences in the kitchen.
Winner: Air fryer. Not even close.
Leftover Chicken
Air fryer: 4–6 minutes at 370°F. Breaded or skin-on chicken regains its crunch. Even plain grilled chicken stays juicy without drying out, as long as you do not overcook it.
Microwave: 1–2 minutes. Faster, and acceptable for plain grilled chicken. However, anything with breading or crispy skin will come out soft and chewy.
Winner: Air fryer for texture; microwave wins on speed when crispiness does not matter.
Frequently Asked Questions
Can an air fryer replace a microwave?
Not entirely. An air fryer cannot efficiently heat liquids, steam food, or defrost as quickly as a microwave. The two appliances complement each other well. An air fryer handles cooking and crisping, while a microwave excels at rapid reheating of soups, beverages, and soft foods. Most kitchens benefit from having both.
Is an air fryer healthier than a microwave?
It depends on what you are cooking. An air fryer can produce crispy results with little or no oil, making it a healthier alternative to deep frying. A microwave does not add or remove fat — it simply heats food. Neither appliance is inherently unhealthy. The health impact comes down to the food itself, not the method of heating.
Does an air fryer use more electricity than a microwave?
Yes, generally. A typical air fryer draws 1,200–1,800 watts and runs for 8–25 minutes per use, while a microwave draws 600–1,200 watts for 1–5 minutes. The microwave uses less total energy per session because of its shorter run time. However, neither appliance uses as much energy as a full-size oven.
Which is better for reheating leftovers?
It depends on the food. For anything that was originally crispy — pizza, fries, fried chicken, breaded items — the air fryer is far superior. For soups, rice, pasta, and beverages, the microwave is the better choice. A good rule of thumb: if the food had a crunch when it was fresh, reheat it in the air fryer.
