Oven to Air Fryer Calculator

Use this when a recipe gives a conventional oven time and temperature. The answer is a safe starting point, not a promise.

Best forOven, fan oven, packet and frozen-food instructions.

Main cautionUse the range, then check food from the early minute.

Use the answer as a starting point. Check early, avoid crowding the basket, and use a thermometer for meat, fish and reheated food.

Your air fryer starting point

Chicken breast

180C17-21 min

Turn or shake: Turn once halfway through
Safety: Chicken breast: use 75C in the centre as the practical target. This matches an FSA/GOV.UK temperature-time option of 75C for 30 seconds, but packet instructions and appliance manuals still take priority. Use a clean food thermometer when you can.
Estimated cost: £0.13 per cook, about £0.66 for 5 uses
Oven comparison: A 2500W oven for the original time is roughly £0.26.

This result starts by lowering oven temperature, shortening time, then adjusting for the food, frozen state, air fryer style and model. Times vary by thickness. Use a food thermometer for best results. Brand alone does not justify a timing change; use the exact model, drawer style and your own repeated results.

How to convert a conventional oven instruction

Enter the conventional oven setting exactly as written. The calculator normally starts lower and shorter because a basket air fryer has a smaller chamber and more concentrated airflow. Keep the original food quantity in mind: a full oven tray does not become one crowded air fryer drawer.

Check before using the result

Use the lower end for thin, separated pieces.
Use the upper end for thick food or a fuller basket.
Check the centre of meat and filled food before serving.

Plain safety rule

Treat every result as a starting point. Check early, leave space for airflow, and use a food thermometer for meat, fish and reheated food.

FAQ

Quick answers

Is the calculator exact?

No. It gives a sensible starting range because food thickness, basket load and air fryer design change cooking time.

Why is there a check-from time?

The check time helps prevent overcooking and gives you a chance to turn, shake or test the centre.

Can I use it for packet instructions?

Yes. Enter the packet oven temperature and time, then choose frozen or chilled where available.
