The short answer
If you only want one recommendation: Cosori 6.8 Qt Smart Air Fryer. If the deciding factor is crispy reheats and small-batch cooking a microwave can't touch, a versatile mid-size air fryer is the buy — the microwave stays your fast tool for liquids and steaming.

📑 Table of contents
Air fryer and microwave aren’t really competitors — they use completely different heating methods for mostly different jobs. But there’s one task where people genuinely choose between them, and the difference in outcome is dramatic.
Where microwave wins outright
Speed for liquids and pre-cooked soft foods: reheating soup, melting butter, cooking rice, steaming vegetables. Microwave heats water molecules directly and does these jobs in a fraction of the air fryer’s time.
No preheat needed: microwave is instant-on. Air fryer typically needs 2-3 minutes of preheat for best results.
Genuinely can’t be replaced by an air fryer: liquids, anything requiring even internal heating without a crust (baby food, melting chocolate).
Where air fryer wins outright
Anything you want crispy: fries, frozen snacks, breaded proteins. Microwave makes these soft/soggy; air fryer keeps or restores crisp texture.
Reheating fried or crispy leftovers: this is the single biggest reason people switch. Microwaved leftover fries or pizza go rubbery; air-fried leftovers come back crisp, often close to fresh-cooked texture.
The reheating comparison (the task people actually compare)
| Food | Microwave result | Air fryer result |
|---|---|---|
| Leftover pizza | Soggy crust, rubbery cheese | Crisp crust, properly melted cheese |
| Leftover fries | Limp, soft | Crisp, close to fresh |
| Fried chicken | Soggy coating | Coating re-crisps |
| Leftover rice | Fast, even reheat | Slower, dries edges if not covered |
| Soup/liquids | Fast, ideal | Not suitable — no basket for liquids |
For reheating specifically: if the food originally had a crispy texture, air fryer wins clearly. If it's soft or liquid, microwave wins clearly. There's very little genuine overlap where either does equally well.
Can you own just one?
If you had to pick only one appliance: microwave covers more daily-use cases (reheating any food, cooking rice, steaming, melting) since it handles liquids and doesn’t require a crisping outcome. Air fryer is the specialist tool — better at its narrow job, unable to do microwave’s broader range at all.
Most kitchens end up keeping both because they solve non-overlapping problems, not because of brand loyalty to one or the other.
FAQ
Is an air fryer better than a microwave? Neither is universally better — they do different jobs. Air fryer wins for anything crispy (proteins, frozen snacks, reheating fried leftovers). Microwave wins for liquids, speed, and foods that don’t need a crust.
Can an air fryer replace a microwave? No — air fryers can’t handle liquids (soup, melting butter) or match microwave’s near-instant reheat speed for soft foods like rice or steamed vegetables.
Which is faster, air fryer or microwave? Microwave, for most tasks — no preheat needed and it heats faster overall. Air fryer’s advantage is texture (crispness), not raw speed.
Is reheated air fryer food better than microwaved? For anything originally crispy (pizza, fries, fried chicken) — yes, noticeably. For soft or liquid foods, microwave produces a better result faster.
Which uses less electricity? Microwave typically uses less energy per use due to shorter cook times and no preheat requirement, though the difference is minor for occasional home use.
