What does this tool do?
Air fryers move hot air quickly around a small basket, so food cooks faster and browns sooner than in a full oven. As a starting point, lower the oven temperature by about 15 °C and shorten the time by roughly 20%.
The Formula
Air-fryer temperature = oven temperature − 15 °C (10 °C for a fan oven); time = oven time × 0.8Frequently Asked Questions
Do I need to preheat an air fryer?
Preheating for 3–5 minutes gives more consistent browning, especially for small or quick items. Add that time separately because it is not part of the cooking estimate.
Can I convert any oven recipe?
It works best for dry-heat foods such as vegetables, chicken pieces, fries and baked goods in small portions. Wet batters, large roasts and dishes with loose sauce need a different approach.
