210°C Oven to Air Fryer: Use 190°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 210°C, set a typical basket air fryer to 190°C (190°C / 374°F) and plan on about 80% of the oven time. At this oven setting people usually cook puff pastry, sausage rolls, extra-crisp chips. The 20% rule is a starting point; Pastry colours fast. Check 4 minutes early.
How to convert 210°C to an air fryer
- 1Read the oven recipe: it calls for 210°C (210°C / 410°F).
- 2Preheat the air fryer to 190°C (190°C / 374°F), not 210°C.
- 3Multiply the oven minutes by 0.8. Example: sausage rolls that bake 25 minutes at 210°C becomes about 20 minutes at 190°C until the pastry is dry and blistered.
- 4Cook in a single layer and check early. Pastry colours fast. Check 4 minutes early.

What 210°C is usually used for
In a conventional oven, 210°C is the setting for puff pastry, sausage rolls, extra-crisp chips. Converting that heat without thinking about the food is why people burn cookies or undercook a joint.
Worked example: sausage rolls that bake 25 minutes at 210°C. In the air fryer that is about 20 minutes at 190°C until the pastry is dry and blistered.
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 210°C in an air fryer would over-brown the outside before the middle caught up. Setting it to 190°C instead gives you the same finish in less time.
What to watch at 190°C
Pastry colours fast. Check 4 minutes early.
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 6 in an air fryer
210°C is roughly gas mark 6. If your recipe is written in gas marks, convert to 210°C / 410°F first, then apply the same drop to get 190°C / 374°F in the air fryer.
Frequently Asked Questions
What is 210°C in an air fryer?
190°C, which is 190°C / 374°F. Reduce the cooking time by about 20% as well, then check early.
What foods are usually cooked at 210°C?
puff pastry, sausage rolls, extra-crisp chips. Example conversion: sausage rolls that bake 25 minutes at 210°C becomes about 20 minutes at 190°C until the pastry is dry and blistered in the air fryer.
Why not just use 210°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.
