230°C Oven to Air Fryer: Use 210°C
Drop the temperature by 20°C and cut the time by 20% as a starting point.
Published by the RecipeAirFryer editorial team · How we source times · Updated
Times and temperatures come from our reviewed cooking database. Explanatory text on each page is generated from that entry so the numbers stay consistent.
If a recipe says 230°C, set a typical basket air fryer to 210°C (210°C / 410°F) and plan on about 80% of the oven time. At this oven setting people usually cook artisan bread slashes, very hot roasting, preheated steel recipes. The 20% rule is a starting point; Most basket air fryers max out near here. If yours cannot hold 210°C, use 200°C and add time.
How to convert 230°C to an air fryer
- 1Read the oven recipe: it calls for 230°C (230°C / 446°F).
- 2Preheat the air fryer to 210°C (210°C / 410°F), not 230°C.
- 3Multiply the oven minutes by 0.8. Example: a small loaf that would bake 30 minutes at 230°C becomes about 24 minutes at 210°C with foil if the crust races ahead.
- 4Cook in a single layer and check early. Most basket air fryers max out near here. If yours cannot hold 210°C, use 200°C and add time.

What 230°C is usually used for
In a conventional oven, 230°C is the setting for artisan bread slashes, very hot roasting, preheated steel recipes. Converting that heat without thinking about the food is why people burn cookies or undercook a joint.
Worked example: a small loaf that would bake 30 minutes at 230°C. In the air fryer that is about 24 minutes at 210°C with foil if the crust races ahead.
Why the temperature drops
An oven heats mostly by radiation from its elements and by slow convection. An air fryer is a small chamber with a fan driving air across the food at speed, so heat transfers into the surface much faster at the same dial setting.
That is why 230°C in an air fryer would over-brown the outside before the middle caught up. Setting it to 210°C instead gives you the same finish in less time.
What to watch at 210°C
Most basket air fryers max out near here. If yours cannot hold 210°C, use 200°C and add time.
Dense items such as a whole chicken may need close to the original oven time because heat still has to travel to the centre. Go by internal temperature, not only the converted clock.
Gas mark 8 in an air fryer
230°C is roughly gas mark 8. If your recipe is written in gas marks, convert to 230°C / 446°F first, then apply the same drop to get 210°C / 410°F in the air fryer.
Frequently Asked Questions
What is 230°C in an air fryer?
210°C, which is 210°C / 410°F. Reduce the cooking time by about 20% as well, then check early.
What foods are usually cooked at 230°C?
artisan bread slashes, very hot roasting, preheated steel recipes. Example conversion: a small loaf that would bake 30 minutes at 230°C becomes about 24 minutes at 210°C with foil if the crust races ahead in the air fryer.
Why not just use 230°C in the air fryer?
You can, but the outside will brown or burn before the inside is cooked. The fan transfers heat into the food far faster than an oven does, so the lower setting gives a more even result.
Do I need to preheat the air fryer?
A 2-3 minute preheat helps for anything breaded, frozen or that you want crisp. For longer cooks it makes little difference.
