Air fryer vs. oven: what an air fryer actually is, and when to use each
It's not frying and it's not magic. It's a small, fast convection oven — and that explains exactly where it wins and where it doesn't.
Half of our recipes give air-fryer and oven timings. They're not the same numbers, and the reason tells you when to reach for which.
What's inside the box
An air fryer is a compact convection oven: a heating element and a strong fan in a small chamber. Because the space is tiny and the air moves fast, food heats quickly and surfaces dry out sooner — and a dry surface is what browns and crisps. No oil is "fried" into anything; a light brush of oil simply helps the crumbs colour.
Where the air fryer wins
- Crispy coatings — the chicken burger fillets, anything breaded. Hot moving air crisps every side.
- Small batches — six cookies, a couple of portions. No preheating, done in minutes.
- Energy — heating a 5-litre basket costs far less than a 60-litre oven.
Where the oven wins
- Anything that needs to spread or rise evenly — a full tray of cookies, brownies, cinnamon rolls. The fan in an air fryer can set the top before the middle is done, and it blows parchment around.
- Big batches — four rounds in the basket is slower than one tray.
- Gentle bakes — cheesecake-style textures don't like blasting air.
Converting a recipe
A rough rule: drop the temperature by about 20 °C and check 25–30 % earlier than the oven time. Our chocolate chip cookies go 15 minutes in the oven at 180 °C, about 10 minutes in the air fryer. Line the basket with parchment, leave space between pieces, and flip anything breaded halfway.
