325°F Oven to Air Fryer: Use 300°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 325°F, set a typical basket air fryer to 300°F (149°C / 300°F) and plan on about 80% of the oven time. At this oven setting people usually cook cookies, muffins, banana bread. The 20% rule is a starting point; Sugar browns faster in the fan. Pull when a skewer is almost clean.
How to convert 325°F to an air fryer
- 1Read the oven recipe: it calls for 325°F (163°C / 325°F).
- 2Preheat the air fryer to 300°F (149°C / 300°F), not 325°F.
- 3Multiply the oven minutes by 0.8. Example: muffins that take 18 minutes at 325°F becomes about 14 minutes at 300°F in silicone cups.
- 4Cook in a single layer and check early. Sugar browns faster in the fan. Pull when a skewer is almost clean.

What 325°F is usually used for
In a conventional oven, 325°F is the setting for cookies, muffins, banana bread. Converting that heat without thinking about the food is why people burn cookies or undercook a joint.
Worked example: muffins that take 18 minutes at 325°F. In the air fryer that is about 14 minutes at 300°F in silicone cups.
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 325°F in an air fryer would over-brown the outside before the middle caught up. Setting it to 300°F instead gives you the same finish in less time.
What to watch at 300°F
Sugar browns faster in the fan. Pull when a skewer is almost clean.
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 3 in an air fryer
325°F is roughly gas mark 3. If your recipe is written in gas marks, convert to 163°C / 325°F first, then apply the same drop to get 149°C / 300°F in the air fryer.
Frequently Asked Questions
What is 325°F in an air fryer?
300°F, which is 149°C / 300°F. Reduce the cooking time by about 20% as well, then check early.
What foods are usually cooked at 325°F?
cookies, muffins, banana bread. Example conversion: muffins that take 18 minutes at 325°F becomes about 14 minutes at 300°F in silicone cups in the air fryer.
Why not just use 325°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.
