Oven to Air Fryer Converter
Convert an oven recipe to air fryer time and temperature - honestly, as a starting point.
Treat this as a starting point, not a guarantee. Air fryers vary a lot by model and basket size, so check the food 5–10 minutes before the adjusted time, shake or turn it, and go by colour and a thermometer rather than the clock. Delicate bakes, batters and anything with a wet coating are the ones most likely to need a hand-tweak.
What this tool does
To convert an oven recipe for an air fryer, drop the temperature by about 20°C (from a conventional oven) and cut the time by about 20%. So 200°C for 30 minutes becomes roughly 180°C for 24 minutes. From a fan oven, which already circulates hot air like an air fryer, drop only about 10°C. This is manufacturer guidance and a rule of thumb, not a formula - treat it as a starting point and check the food early.
Converts an oven temperature and time to air-fryer settings in °C or °F, and converts back the other way too.
Treats a fan (convection) oven differently from a conventional one, and says plainly that the result is a starting point to check, not an exact answer.
How to use it
- Enter the temperature and time from your oven recipe, and pick °C or °F.
- Say whether your oven is conventional or fan - it changes how much to reduce the temperature.
- Read off the air-fryer temperature and time, then check the food a few minutes early and adjust.
Why use this converter
Air fryers circulate hot air in a small space, so oven recipes cook faster at a lower temperature, but the right adjustment depends on the model and the food. A starting point saves guessing and overcooked meals.
Why we built it
We built the oven to air fryer converter to treat fan and conventional ovens differently and to call its answer a starting point, not a promise. Convert quantities with the cups to ml converter and ingredient weights with the ml to grams converter.

Who this tool is for
- Home cooks adapting oven recipes to an air fryer
- Anyone with a new air fryer and old recipes
- Meal-preppers
When to use it
- Adapting an oven recipe for an air fryer.
- Converting from a fan oven or a conventional oven.
- Working out a first temperature and time before checking.
- Converting an air-fryer recipe back to an oven.
The rule, and where it falls short
Two adjustments, one honest caveat.
The widely used guidance is to lower the temperature by about 20°C (25°F is the rough US shorthand) and shorten the time by about 20%. An air fryer is essentially a small, fiercely efficient fan oven: hot air is blown hard across food in a tiny chamber, so the surface cooks faster and browns sooner than in a big oven. Lowering the heat stops the outside scorching before the inside is done; shortening the time reflects how much quicker it gets there.
Where it falls short is that "about" is doing real work. A 1.8-litre basket model and a 7-litre oven-style model are not the same machine, baskets crowd differently from oven shelves, and a thick casserole behaves nothing like a tray of chips. That is why this tool rounds to sensible dial values and then tells you to check early rather than pretending the number is exact.
Set a timer for a few minutes before the converted time, open the drawer, and look. Air fryers lose almost no heat when opened, so checking often costs you nothing and saves dinner.
Conventional oven vs fan oven
This is the step most converters skip.
A fan (convection) oven already moves hot air around, and its dial is usually set about 20°C below a conventional oven for the same recipe. An air fryer is a more extreme version of the same idea. So the reduction you need depends on where you are starting from: from a conventional oven, drop about 20°C; from a fan oven, drop only about 10°C, because a chunk of the adjustment is already baked into the fan setting.
If you reduce a fan-oven temperature by the full 20°C, you risk pale, undercooked food. Picking the right oven type above is what keeps the conversion honest.
What converts well, and what doesn't
Things that love an air fryer: chips and roast potatoes, chicken pieces, sausages, bacon, frozen breaded food, roasted vegetables, reheated leftovers - anything where a crisp, browned surface is the goal.
Things that fight it: loose batters and wet coatings (they blow around before they set), delicate cakes and soufflés (the fan can pull them lopsided), large joints that need long, even, gentle cooking, and anything that must not brown. For those, the oven is often still the better tool, and the conversion is only a rough guide.
Preheating helps for anything you want crisp - two or three minutes is plenty for most models. And leave space: a crowded basket steams instead of crisping, which is the single most common reason a converted recipe disappoints.
What you give it, and what you get back
| Item | Details |
|---|---|
| Input | Oven temperature, cooking time and whether the oven is conventional or fan. |
| Output | Air-fryer temperature and time, in °C or °F. |
| Direction | Switch to convert from air fryer to oven. |
Issues you may run into
| What you see | Why it happens | What to do |
|---|---|---|
| Food is undercooked or burnt | Every air fryer and food differs. | Check early and adjust. |
| Different advice from the manual | The tool uses a general rule. | Follow the appliance manual. |
| Meat safety | Time is not a safety measure. | Use a food thermometer. |
Assumptions and limitations
- This is a rule of thumb from manufacturer guidance, not a formula. Every model and basket size cooks differently.
- The temperature reduction assumes a standard air fryer. Oven-style and dual-basket models can behave more like a small fan oven.
- It does not adjust for the food itself. A thick bake and a thin tray of chips convert by the same rule but behave very differently, so always check early.
- The Fahrenheit shorthand (about 25°F) and the metric rule (20°C) are not exactly equal; this tool works to the 20°C basis and rounds to the nearest 5°.
- It is not cooking advice for food safety. Use a thermometer for meat rather than the clock.
Frequently asked questions
Do you reduce the temperature for an air fryer?
Yes. From a conventional oven, drop the temperature by about 20°C (roughly 25°F). Air fryers blow hot air hard across food in a small space, so the surface cooks and browns faster; lowering the heat stops the outside burning before the inside is cooked. From a fan oven, reduce by only about 10°C.
How much less time does an air fryer need?
About 20% less as a starting point - multiply the oven time by 0.8. So 30 minutes in the oven is roughly 24 minutes in the air fryer. Because models vary, check the food a few minutes before that and go by how it looks rather than the clock.
Is a fan oven the same as an air fryer?
Almost - an air fryer is essentially a small, very powerful fan oven. Both cook by blowing hot air around. The differences are size and intensity: an air fryer's chamber is tiny and its fan is fierce, so food crisps faster. That is also why you reduce a fan-oven temperature less than a conventional one when converting.
Do I convert differently from a fan oven?
Yes. A fan oven is usually already set about 20°C below a conventional oven, so a lot of the adjustment is done. From a fan oven, drop only about 10°C rather than the full 20°C, or you risk undercooking. Pick your oven type in the tool and it handles this for you.
Does the air fryer conversion work for every food?
No. It works best for things you want crisp - chips, chicken, sausages, roasted vegetables, frozen breaded food. Loose batters, delicate cakes, large joints and anything that must not brown convert badly, and the oven is often still the better choice. Treat the numbers as a guide and check early.
Should I preheat the air fryer?
For anything you want crisp, a short preheat of two to three minutes helps, though many models cook fine from cold with a slightly longer time. More important than preheating is not overcrowding the basket - a crowded basket steams food instead of crisping it.
