Oven to Air Fryer Converter
Enter the oven temperature and cook time from your recipe. The converter lowers the temperature by 25°F (Ninja's published rule; about 14°C) and tells you when to start checking, using Cosori's suggestion of roughly half the oven time as the first check. A timer cannot tell you food is safe: finish meat, poultry and fish at the USDA safe minimum internal temperature, shown below the result. Everything runs in your browser; nothing is uploaded or stored.

How it works
An air fryer is a small convection oven with a powerful fan close to the food, so it browns faster than a full-size oven at the same setting. The usual fix is to lower the heat and shorten the time. Ninja's FAQs give one number for temperature: reduce it by 25°F. For time, Cosori suggests starting at about half; this converter tells you to check then and gives about 80% of the oven time as the likely upper end, because crowded baskets and thick pieces take longer. Results are rounded to the nearest 5 degrees and capped at 400°F (205°C), the top setting on many basket fryers; check your model's maximum.
USDA safe minimum internal temperatures
| Food | Safe minimum |
|---|---|
| Poultry (whole, pieces, ground) | 165°F (74°C) |
| Ground meats (beef, pork, veal, lamb) | 160°F (71°C) |
| Beef, pork, veal, lamb steaks, chops, roasts | 145°F (63°C), then rest 3 minutes |
| Fish and shellfish | 145°F (63°C) |
| Leftovers and casseroles | 165°F (74°C) |

What it does not cover
- Recipes written for convection ovens, which already run cooler; start from the recipe's own convection setting and lower it less.
- Batters and wet coatings, which drip and burn in a basket; see your manual.
- Liners and foil: use only what your manual allows. More in our oven to air fryer conversion guide.

Frequently asked questions
How do I convert oven temperature to air fryer?
Lower it by about 25°F (about 14°C). Ninja's air fryer FAQs give exactly that rule: reduce the conventional oven temperature by 25°F. Cosori suggests 15 to 25 degrees lower as a starting point.
How much shorter is the air fryer time?
Start checking at about half the oven time, which is Cosori's suggested starting point, and expect most foods to finish somewhere between half and about four fifths of it. Smaller pieces finish sooner; crowded baskets take longer.
How do I know it is done?
Use a food thermometer, not the timer. USDA safe minimum internal temperatures: 165°F for poultry, 160°F for ground meats, and 145°F for whole cuts of beef, pork, veal and lamb (with a 3 minute rest) and for fish.
Does this work for baking?
As a starting point, yes, but cakes and breads can brown on top before the middle sets in a small, fast-moving air chamber. Lower the temperature, cover the top loosely if your manual allows foil, and test the center.
