How do you convert oven time and temperature to an air fryer?
Convert any oven recipe to air fryer settings: lower temperature, shorter time, and when to check first.
Quick answer
An air fryer is a small convection oven with an aggressive fan, and that’s the whole conversion secret: moving hot air transfers heat faster than the still air of a conventional oven, so the same dish needs about 20 °C less and roughly 20% less time. A recipe written for 200 °C / 30 minutes in the oven becomes 180 °C / 24 minutes in the basket. The calculator applies exactly this and adds the number that saves dinners: when to check for the first time, at about three quarters of the converted time, because baskets, wattages and food sizes vary more between air fryer models than between ovens.

The standard conversion: lower the temperature by ~20 °C and cut the time by ~20%, because the fan moves hot air much more efficiently than a static oven. Always check earlier the first time — baskets and models vary. Don’t overcrowd the basket (air must circulate), shake or flip halfway, and skip preheating for most foods. Baked goods with delicate rises (soufflés, some cakes) remain oven territory.
How it works
Three habits complete the conversion. Don’t overcrowd — the fan needs space around the food, so a single layer with gaps beats a full basket cooked once (do two batches instead). Shake or flip halfway through anything that doesn’t lie flat. And skip preheating for most foods; the small chamber reaches temperature in the first minute or two. What doesn’t convert: anything with a wet batter (it drips through the basket before setting) and delicate rises like soufflés — those remain oven territory.
Frequently asked questions
How do I convert an oven recipe to the air fryer?+
Lower the temperature by 20 °C and reduce the time by 20%, then check at about three quarters of the new time. Example: oven 220 °C for 25 minutes becomes air fryer 200 °C for 20 minutes, first check at 15. For frozen foods that list oven instructions, the same rule applies and usually lands even faster.
What are the times for the most common foods?+
Reliable starting points at 180-200 °C: frozen fries 15-18 min, fresh-cut fries 20-25, chicken breast 12-15, whole chicken thighs 20-25, fish fillets 8-12, vegetables 10-15, reheated pizza 3-4 min at 160 °C. All with a shake or flip halfway. Your model may run 2-3 minutes off these — note your own numbers the first time.
Do I need to preheat the air fryer?+
Rarely. The small chamber reaches temperature in 1-2 minutes, so for most foods just add a minute to the total. Preheating helps only when searing matters — steak, burgers — or for very short cooks (under 8 minutes) where those first cold minutes are a big share of the total.
Why is my air fryer food dry?+
The fan is a dehydrator if misused. Usual causes: temperature converted but time left at the oven value (the classic error this calculator prevents), no oil at all — lean meats and vegetables want a light spray, half a teaspoon does the job — or pieces cut too small. Fatty foods (wings, sausages, salmon) self-baste and rarely dry out; lean chicken breast benefits from a brine or marinade.
