Convert an oven recipe to air fryer time and temperature by what you are actually cooking, with a check-early time, the safe internal temperature, and a batch count.
Change the inputs that matter to your decision. Optional assumptions stay collapsed until you need them.
Food type drives the conversion — frozen, roast, and baked goods each follow a different rule.
Optional. Crowding the basket steams food instead of crisping it.
A 400 °F oven recipe for 30 minutes becomes 375 °F (190 °C) for 23–24 min, cooked to 165 °F (74 °C).
Cook to temperature, not to time. Take the reading in the thickest part, clear of the bone.
| Air fryer temperature | 375 °F (190 °C)25 °F below the recipe's 400 °F |
|---|---|
| Check at | 23 minAir fryers vary enough that the first check matters more than the target |
| Expect done by | 24 min |
| Original recipe | 400 °F for 30 min |
| Safe internal temperature | 165 °F (74 °C)USDA minimum for all poultry |
The reduction depends on what you are cooking, which is why food type is an input rather than a fixed rule. Where a recipe converts below the lowest setting an air fryer can hold, the tool says so instead of returning a temperature hotter than the recipe asked for. Cook meat and poultry to the internal temperature, not to the clock.
Practical notes about the inputs, assumptions, and result.
No, and that is the rule most air fryer guides give while their own tables contradict it. Frozen convenience food is already cooked and browned, so it keeps the package temperature and takes about half the time. Baked goods take only about 15 °F off because the crumb needs time to set before the outside colours. Roasts take the reduction but benefit least from an air fryer at all.
Then the recipe is a poor air fryer candidate, and the result says so. Most models will not hold below about 175 °F. Quietly raising the setting to the machine's floor — which is what a clamped conversion does — gives you a temperature hotter than the recipe asked for and no warning that it happened. A low, slow braise or custard belongs in the oven.
Because air fryers vary far more than ovens do. Wattage, basket geometry, and fan speed differ enough between models that the same setting can be 20% apart in effect. The earlier figure is when to open the basket and look; the later one is when to expect it done. For anything with a safe internal temperature, the probe decides, not the clock.
One layer, with space around each piece. An air fryer is a small convection oven and it works by moving hot air past every surface. Pile food up and the moisture it releases cannot escape, so it steams instead of crisping — the single most common reason air fryer food disappoints. Give a quantity and a basket size and the result tells you how many batches that is.
For most things, three to five minutes helps, and it matters most for anything you want browned on contact — steak, chops, or a crust. Small baskets come up to temperature fast, so it is a short wait. The times here assume a preheated basket.
Poultry 165 °F, whole cuts of beef, pork, and lamb 145 °F with a three-minute rest, ground meat 160 °F, fish 145 °F, and reheated leftovers 165 °F. These are the USDA minimums and they override anything on this page. An instant-read thermometer is the only way to know, and in an air fryer — where the outside colours fast — it matters more than usual.
