Convert an oven recipe for the air fryer (or back)
The recipe says 200°C for 30 minutes — your air fryer needs lower and shorter. The rule of thumb, applied both directions.
Tools used in this guide
The job
An air fryer is a small, fierce convection oven — the fan makes heat transfer faster, so the same setting burns food. The common conversion is −20°C and −20% time; going the other way (fryer recipe → oven) adds them back.
Convert either way
Enter the recipe's temperature and time, pick the direction, get the converted setting. Works in °C or °F, times up to 24 hours, temperatures 60–260°C.
- 200°C / 30 min in the oven becomes roughly 180°C / 24 min in the fryer.
- Packed baskets heat slower — a full basket needs a few extra minutes even after conversion.
Trust but verify
The rule is a starting point, not a guarantee — models, load size and preheating all shift real results. First time with a converted recipe, check a few minutes early.
