Air Fryer vs Oven: Two Years On, Here's My Honest Verdict

I held out against air fryers for longer than most. The combination of relentless social media hype and the knowledge that most kitchen gadgets end up in a cupboard within six months made me resistant. Then a friend who is a genuinely good cook (not just someone who posts food photos) told me she'd been using one daily for eighteen months and found it useful in specific, definable ways. That was enough to make me try one.

I've had a Ninja Dual Zone air fryer for two years now. It gets used almost every day. It has also failed to replace my oven in the ways I initially expected, and has proved surprisingly useful in ways I didn't anticipate.

What Air Fryers Actually Do

An air fryer is essentially a compact convection oven. It circulates hot air around food very quickly in a smaller space, which achieves three things: it preheats faster than a full oven (2–3 minutes vs 10–15), it cooks faster for most things (roughly 20–30% less time), and it produces crispier results on the outside of food because the rapid air movement draws moisture away from surfaces more aggressively.

It does not fry things. The name is misleading. You get crispy results without oil, or with a light coating, but it's not the same as deep frying. Chips (crisps, UK sense) from an air fryer are better than oven chips but different from deep-fried chips.

The Honest Comparison

Where It's Changed How I Cook

Reheating is the thing I didn't anticipate. My air fryer has almost entirely replaced my microwave for reheating food. Leftover pizza, reheated in an air fryer for 3–4 minutes, is noticeably better than microwaved pizza – the base goes crispy again rather than becoming soft and rubbery. Leftover roast potatoes, reheated in an air fryer, are basically as good as they were fresh. This is not something I expected to care about but it turns out I care about it quite a lot.

Weeknight cooking speed is the other genuine win. If I'm cooking chicken thighs, roasted veg and a grain on a Tuesday evening, doing the chicken in the air fryer (20 minutes from cold, no preheat) while the oven handles the larger tray of veg means everything finishes closer to the same time and the overall process is faster.

What It Doesn't Do Well

Baking. I tried making scones in the air fryer. I won't describe the results in detail, but they were not scones. The combination of rapid circulating heat and limited space creates uneven browning and erratic rising for anything that relies on steady, enclosed heat. My oven stays for anything I bake.

Capacity is a genuine limitation for households of more than two people. My Ninja Dual Zone has two 3.8L drawers, which is enough for dinner for two but becomes constrained for three or more. The large-format air fryer ovens (Cosori's range, the Ninja Foodi MAX) address this but take up considerably more counter space.

Smell. The air fryer is very efficient at circulating cooking smells through the kitchen. Bacon and strong fish are particularly noticeable. This isn't unique to air fryers but the speed and intensity of the air circulation makes it more pronounced than oven cooking.
