Air fryer temperature & time
Oven to air fryer chart
| Oven (temp / time) | Air fryer temp | Air fryer time |
|---|---|---|
| 350°F / 20min | 325°F | 16 min |
| 375°F / 25min | 350°F | 20 min |
| 400°F / 30min | 375°F | 24 min |
| 425°F / 35min | 400°F | 28 min |
| 450°F / 40min | 425°F | 32 min |
Air fryers run hotter and circulate air, so food cooks faster. Check 5 minutes before the calculated time the first time you make a recipe, then adjust.
Frequently asked questions
How do you convert oven temperature to an air fryer?
Lower the oven temperature by 25°F (about 15°C) and reduce the cooking time by roughly 20%. Always check for doneness early.
Do you preheat an air fryer?
Most air fryers benefit from a 2-3 minute preheat, though many small models don't require it. Check your manual.
Can you put foil in an air fryer?
Yes, but don't block the airflow — keep foil weighted down and away from the heating element, and never cover the whole basket.
