What temperature should I use in an air fryer instead of an oven?
A good starting point is to subtract 25°F from the oven temperature. For Celsius recipes, subtract about 15°C.
Temperature Conversion
Oven to Air Fryer Temperature Conversion
Use this guide when your recipe gives a conventional oven temperature but you want to cook it in an air fryer. The goal is not to invent a new recipe; it is to choose a safer starting temperature, then adjust based on food thickness, browning, and your specific basket.
Quick Answer
For most oven-to-air-fryer conversions, lower the oven temperature by about 25°F, or about 15°C. That means 400°F in the oven becomes about 375°F in the air fryer, while 350°F becomes about 325°F.
- Oven Fahrenheit rule: subtract 25°F for the air fryer.
- Oven Celsius rule: subtract about 15°C for the air fryer.
- Keep the temperature closer to the original for frozen snacks that need crisping, but watch them closely.
- Use the lower end of the time range first, because air fryers brown faster than ovens.

Why this conversion
Applied the standard 20% time reduction and 25°F temperature drop.
Shake / Flip
Shake or flip around 12 minutes for even crisping.
Doneness check
Check early and add 2–3 minutes if needed.
* Air fryer models vary. Always check food early and use a food thermometer for meats.
How the Temperature Formula Works
Air fryers behave like compact convection ovens. The heating element is close to the food, the cooking chamber is small, and the fan moves hot air aggressively around the basket. That is why an oven recipe often needs a lower air fryer temperature: the food sees heat more directly and browns faster.
The standard starting point is simple: air fryer temperature equals oven temperature minus 25°F. If you cook in Celsius, use oven temperature minus about 15°C. This is a practical kitchen rule, not a lab guarantee. It gives you a reasonable first setting for foods like chicken pieces, roasted vegetables, frozen snacks, potatoes, and many reheated leftovers.
Do not treat the formula as a promise that every food will be perfect. Very delicate baked goods can brown too fast even at the converted temperature. Thick meat may need the same converted temperature but more time. Wet batters, covered casseroles, and large oven dishes often do not translate cleanly to a basket-style air fryer.
Common Oven to Air Fryer Temperature Chart
Use this table as a quick reference when the recipe gives only an oven temperature. Pair it with a shorter cooking time and check food early.
| Oven Temperature | Air Fryer Starting Temperature | Best Starting Use |
|---|---|---|
| 300°F / 150°C | 275°F / 135°C | Very gentle reheating, delicate custards, low-temperature baking trials |
| 325°F / 165°C | 300°F / 150°C | Muffins, tender baked goods, foods that brown easily |
| 350°F / 175°C | 325°F / 160°C | Cookies, breads, leftovers, smaller casserole-style portions |
| 375°F / 190°C | 350°F / 175°C | Chicken pieces, pork chops, vegetables, general roasting |
| 400°F / 200°C | 375°F / 190°C | Chicken wings, frozen snacks, roasted potatoes, crisping foods |
| 425°F / 220°C | 400°F / 200°C | Fries, bacon, crisp vegetables, fast browning |
| 450°F / 230°C | 425°F / 220°C | Short searing or finishing only; check your air fryer max temperature |
Temperature Examples With Time Context
| Oven Instruction | Air Fryer Estimate | Notes |
|---|---|---|
| 350°F for 20 minutes | 325°F for about 15–17 minutes | Good for small baked items; check browning early. |
| 375°F for 25 minutes | 350°F for about 18–21 minutes | Works for many chicken and vegetable recipes. |
| 400°F for 30 minutes | 375°F for about 22–25 minutes | A common conversion for wings, potatoes, and frozen snacks. |
| 425°F for 15 minutes | 400°F for about 11–13 minutes | Shake or flip halfway for crisping. |
| 450°F for 10 minutes | 425°F for about 7–9 minutes | Use only if your air fryer supports this temperature. |
Practical Tips
- Preheat only when it matters: meats, breaded foods, and frozen snacks usually benefit from a hot basket; quick reheating often does not need it.
- Keep a little space between pieces so hot air can reach the surface; a crowded basket can cook slower even at the right temperature.
- For foods that brown too quickly, keep the converted temperature and reduce it another 10°F to 15°F after the first check.
- For foods that are pale but cooked through, raise the temperature only for the final 2–3 minutes instead of cooking hotter the whole time.
- Use the calculator when food type matters. Fish, baked goods, vegetables, and reheating do better with different time multipliers.
- Write down the setting that worked for your air fryer model. Basket shape and fan strength change the final result.
Common Mistakes to Avoid
- Using the oven temperature unchanged. This often over-browns the outside before the center catches up.
- Dropping the temperature but leaving the full oven time. Air fryer cooking is usually faster, so this can dry food out.
- Assuming Celsius and Fahrenheit reductions are identical. Use 25°F or about 15°C, not 25°C.
- Ignoring the food type. A thick chicken breast and a tray of frozen fries may both start at 400°F in an oven, but they need different checks.
- Trusting the first attempt blindly. Always check early the first time you convert a recipe.
When Not to Rely on Temperature Alone
Temperature conversion is only one part of the decision. Meat, poultry, and fish should be checked with a food thermometer, not only by color or crispiness. Air fryers can brown the outside of food quickly while the center still needs time.
If your original oven recipe uses a covered dish, a very wet batter, or a large casserole, treat the air fryer result as an experiment. Smaller portions and exposed surfaces convert best.
FAQ
What is 400°F oven converted to air fryer?
400°F in a conventional oven usually converts to about 375°F in an air fryer. Start checking food before the original oven time ends.
What is 350°F oven converted to air fryer?
350°F in an oven usually converts to about 325°F in an air fryer. This is common for baked goods, reheating, and gentler cooking.
Should I always reduce air fryer temperature by 25°F?
It is a strong starting rule, but not absolute. Frozen snacks, thick cuts, and delicate baked goods may need small adjustments after the first check.
Is 25°F the same as 15°C?
It is close enough for kitchen conversion. If your recipe is in Celsius, subtract about 15°C from the oven temperature.
