350°F Oven to Air Fryer: Use 325°F
Drop the temperature by 25°F 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 350°F, set a typical basket air fryer to 325°F (163°C / 325°F) and plan on about 80% of the oven time. At this oven setting people usually cook weeknight tray bakes, chicken breast, roasted broccoli. The 20% rule is a starting point; Flatten thick breasts or the converted time will brown the thin end first.
How to convert 350°F to an air fryer
- 1Read the oven recipe: it calls for 350°F (177°C / 350°F).
- 2Preheat the air fryer to 325°F (163°C / 325°F), not 350°F.
- 3Multiply the oven minutes by 0.8. Example: chicken breast that roasts 25 minutes at 350°F becomes about 20 minutes at 325°F, to 74°C / 165°F inside.
- 4Cook in a single layer and check early. Flatten thick breasts or the converted time will brown the thin end first.

What 350°F is usually used for
In a conventional oven, 350°F is the setting for weeknight tray bakes, chicken breast, roasted broccoli. Converting that heat without thinking about the food is why people burn cookies or undercook a joint.
Worked example: chicken breast that roasts 25 minutes at 350°F. In the air fryer that is about 20 minutes at 325°F, to 74°C / 165°F inside.
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 350°F in an air fryer would over-brown the outside before the middle caught up. Setting it to 325°F instead gives you the same finish in less time.
What to watch at 325°F
Flatten thick breasts or the converted time will brown the thin end first.
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 4 in an air fryer
350°F is roughly gas mark 4. If your recipe is written in gas marks, convert to 177°C / 350°F first, then apply the same drop to get 163°C / 325°F in the air fryer.
Frequently Asked Questions
What is 350°F in an air fryer?
325°F, which is 163°C / 325°F. Reduce the cooking time by about 20% as well, then check early.
What foods are usually cooked at 350°F?
weeknight tray bakes, chicken breast, roasted broccoli. Example conversion: chicken breast that roasts 25 minutes at 350°F becomes about 20 minutes at 325°F, to 74°C / 165°F inside in the air fryer.
Why not just use 350°F 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.
