Convert the instruction you already have.

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.

Packet instructions remain the safety reference

Choose one oven instruction from the packet and enter its temperature and time as a pair. The result is an air fryer starting point, not a replacement for storage, allergen, cook-from-frozen or use-by instructions. If the manufacturer provides air fryer directions, use those before this converter.

Check before using the result

Confirm whether the packet says chilled or frozen.
Do not mix fan temperature with conventional oven time.
Check pies, pastries and filled snacks in the centre.

FAQ

Quick answers

What if the packet already gives air fryer instructions?

Use the manufacturer's air fryer instruction first because it is specific to that product.

Can I convert cook-from-frozen food?

Yes when the packet permits cooking from frozen. Keep the product state set to frozen and check dense centres carefully.

Which packet oven column should I use?

Use one complete pair: conventional temperature and time, or fan temperature and its matching time.
