Air Fryer Converter

Air fryers are essentially small, powerful convection ovens — the compact chamber and fast air circulation cook food faster than a conventional oven at the same temperature. A widely used rule of thumb is to lower the oven temperature by 25°F and reduce the cooking time to about 80% of the original.

This is a starting-point conversion, not a guarantee — air fryer basket size, food thickness, and how much you crowd the basket all affect actual cooking time. Always check food for doneness early and use a food thermometer for meat and poultry rather than relying on time alone.

Example: a recipe calling for 400°F for 20 minutes in a conventional oven converts to about 375°F for 16 minutes in an air fryer (400 − 25 = 375; 20 × 0.8 = 16). Check for doneness a few minutes early the first time you try a new recipe.

Air fryers circulate hot air faster than conventional ovens — temperature drops (~25°F) and time reductions (~20%) are starting points.

Crowding the basket blocks airflow — cook in batches even if math says one tray fits.

Worked example: 400°F for 20 min oven → ~375°F for ~16 min air fryer.

Frozen foods often need extra minutes beyond the 80% time rule because the air fryer must first conduct heat through ice crystals. A 20-minute frozen fry instruction might need 18 minutes fresh but 22+ minutes from frozen in the same basket. Frozen items may need minutes beyond 80% time — ice crystals slow heat transfer even after the 400°F→375°F, 20→16 minute conversion.

Convection roast mode on a full-size oven narrows the gap with air fryers — if your oven already has a convection fan, try −15°F and 90% time instead of the full −25°F / 80% shortcut before committing to the sharper conversion. Full-size convection ovens need less aggressive conversion — try −15°F and 90% time if your oven already circulates air strongly.

Default conversion: 400°F oven for 20 minutes → 375°F for 16 minutes in the air fryer. Thicker chicken breasts may need 18 minutes with an internal temp check at 165°F rather than trusting time alone on first run. Thicker chicken breasts may need 18 minutes with a 165°F thermometer check — first run should beat the 16-minute default slightly.
