Air Fryer vs Microwave (2026): Different Jobs, Both Worth Having

The short answer

These aren't really rivals. A microwave reheats and steams fast by exciting water molecules; an air fryer crisps and browns with hot air. The microwave is faster and uses less energy for a quick reheat; the air fryer makes leftovers actually good instead of soggy. Most kitchens want both — but if you can only add one and you already have a microwave, the air fryer expands what you can cook far more.

People pit these two against each other, but they cook in completely different ways. A microwave uses electromagnetic waves to vibrate the water in food, heating it from the inside out — fast, but it can't brown or crisp. An air fryer uses hot, moving air to cook the outside, which browns and crisps but takes longer. They're complements, not substitutes.

The comparison at a glance

Dimension	Air fryer	Microwave
How it heats	Hot circulating air (outside-in)	Microwaves excite water (inside-out)
Crisping / browning	Excellent	None — steams and softens
Speed to reheat	5–10 min	1–3 min
Cost, quick reheat*	~5–8¢	~1–3¢
Best for	Fries, wings, leftovers you want crisp	Liquids, steaming, fast reheats

*Air fryer ~1,500 W for several minutes vs microwave ~1,000–1,200 W for one to two minutes, at the U.S. EIA average rate. The microwave wins pure reheating cost because it's faster. Check your own on the calculator.

Where the microwave wins

For speed and efficiency on the jobs it's built for, nothing beats a microwave: heating a mug of coffee, warming soup, steaming vegetables, softening butter, reheating rice. It finishes in a minute or two and, because it's so fast, it often uses less energy for a simple reheat than an air fryer running for eight minutes. It just can't make anything crispy.

Where the air fryer wins

The air fryer makes leftovers genuinely good. Reheat pizza, fries, fried chicken, or roast potatoes in a microwave and they turn soft and rubbery; do it in an air fryer and they come back crisp, close to fresh. It also cooks from raw — fries, wings, vegetables, proteins — which a microwave can't do with any texture. If “make food crisp” is on your list at all, the air fryer is the tool.

Which should you buy?

If you already own a microwave (most people do), an air fryer is the higher-value addition — it does things the microwave never could and transforms leftovers. If you somehow have neither and can only buy one, the microwave is the more essential all-rounder for speed and basic reheating, but the air fryer is the more fun and versatile cooking appliance. The genuinely right answer for most kitchens is to keep both.

How we picked

We did not lab-test this gear

Everyone in this category says they tested twenty air fryers. We have not lab-tested any of these, and we say so. What we did instead: compiled the published specifications — wattage, capacity, materials — worked out what each machine actually costs to run at the national electricity rate, read the manuals and owner reviews, and scored each one against a published rubric. The scores are judgments from documented research — not measurements we took, because we do not have a lab and we will not pretend we do. Where a number came from someone else's work, we name them in Sources.

Questions

Frequently asked

Is an air fryer better than a microwave?

For different jobs. An air fryer crisps and browns and cooks from raw; a microwave reheats and steams far faster. Neither replaces the other — a microwave can't make food crisp, and an air fryer can't heat a mug of soup in 90 seconds.

Which is cheaper to run, an air fryer or a microwave?

For a quick reheat, the microwave — it's faster, so it draws power for less time (often 1–3 cents versus 5–8 cents). For cooking food from raw with good texture, the air fryer is the only one that can do the job. See the running-cost guide.

Can an air fryer replace a microwave?

Not really. An air fryer can reheat many foods (better, for anything that should be crisp), but it's slower and can't heat liquids, steam, or soften the way a microwave does. They're best kept as a pair.

Does an air fryer reheat food better than a microwave?

For anything that's meant to be crispy — pizza, fries, fried chicken, roast potatoes — yes, clearly. The air fryer restores crunch that a microwave turns to mush. For liquids and soft foods, the microwave is faster and just as good.
