Most kitchens now have both, and many people wonder which one to reach for. The air fryer vs microwave choice comes down to two things: texture and time. One is a speed champion for heating, the other is a mini oven that makes food crispy.

Below we compare what each does best, the real running cost per task and when it makes sense to use them together.
Air fryer vs microwave: the short answer
Use the microwave for fast reheating of soups, drinks, rice and steamed vegetables. Use the air fryer when you want crispy results, such as fries, wings, roasted vegetables or reheated pizza. The microwave is usually cheaper per task because it runs for less time, but both cost only cents.
How each one cooks
A microwave heats the water inside food directly, which is why it is so fast but leaves bread soggy and fries limp. An air fryer is a small convection oven. A heating element and a powerful fan blow hot air around the food, browning and crisping the outside. That takes longer, but the texture is closer to oven-baked or fried food.
Cost per task compared
These examples use a 1,100-watt microwave and a 1,500-watt air fryer at full power, at the 2026 US average price of about 18.2 cents per kWh, according to EIA’s electricity outlook. Real use is often a bit lower.
| Task | Microwave | Air fryer | Better choice |
|---|---|---|---|
| Reheat leftovers | 3 min, about 1 cent | 8 min, about 3.6 cents | Microwave for speed |
| Frozen fries | 6 min, about 2 cents (soggy) | 15 min, about 6.8 cents | Air fryer for crunch |
| Baked potato | 8 min, about 2.7 cents | 40 min, about 18 cents | Microwave, or both |
| Pizza slice | Fast but soft base | A few minutes, crisp base | Air fryer |
6 easy facts to pick the right one
- Speed wins in the microwave. Nothing beats it for a cup of coffee or a bowl of soup.
- Texture wins in the air fryer. Anything that should be crunchy belongs there.
- Cost per use is tiny either way. Most tasks cost a few cents.
- Capacity matters. Small air fryers cook in batches, which adds time for families.
- Combine them. Microwave a potato for a few minutes, then air fry it to crisp the skin.
- Cleaning is different. Microwaves wipe clean, while air fryer baskets need washing after greasy foods.
What about combination models?
Some microwaves now include an air fry or convection mode. They save counter space and can do both jobs, but many people find a dedicated air fryer crisps food faster because the cooking space is smaller. If your kitchen is tight, a combo can make sense. If you cook crispy food often, a separate air fryer usually gives better results.
Which one should a small kitchen keep?
If you can only keep one, think about what you cook most. People who mostly reheat leftovers, warm drinks and make quick meals will miss the microwave more. People who love crispy snacks, roasted vegetables and fresh cooking will lean toward the air fryer. Many small households start with the microwave and add a compact air fryer later.
Quick FAQ
Can an air fryer replace a microwave? For some people, yes, but it is slower at reheating liquids and cannot heat drinks.
Is an air fryer cheaper to run than a microwave? Usually not per task, because it runs longer. The difference is just a few cents.
Can I put metal in an air fryer? Many air fryers allow oven-safe metal pans, unlike microwaves. Check your manual first.
Air fryer vs microwave: a quick recap
- Microwave: fastest for reheating and liquids.
- Air fryer: best for crispy textures.
- Cost: both cost cents per use; the microwave is usually cheaper.
- Smart trick: use both together for speed plus crunch.
