How is air frying different from deep frying?

I’ve been using air fryers for years now and this is probably one of the most common questions I see.

The biggest difference is how the food actually cooks. Deep frying means submerging food in hot oil, usually around 175 to 190°C. That oil transfers heat very quickly and evenly, which is why you get that super crispy, golden exterior. It also means the food absorbs some of that oil, which adds flavor but also a lot of calories.

Air frying, on the other hand, is basically a small convection oven. It uses a fan to circulate very hot air around the food. You might add a tiny bit of oil, or none at all, but it’s nowhere near the amount used in deep frying. The “crispiness” comes from dry heat and airflow rather than oil immersion.

In terms of texture, deep frying still wins if you’re chasing that classic restaurant-style crunch. Things like fried chicken or donuts just come out richer and more evenly crispy. Air fryers get close, especially with foods that already have some fat in them, but it’s not exactly the same. Sometimes it’s a bit drier or less evenly browned.

Where air fryers really shine is convenience and cleanup. No big pot of oil, no dealing with disposal, way less smell lingering in your kitchen. It’s also generally healthier since you’re cutting down a lot of added fat.

So it’s not really a 1:1 replacement. Think of air frying as a lighter, easier version that gets you maybe 80 to 90 percent of the way there for most foods, without the mess and extra calories.
