Air fryer conversion (convert oven to air fryer)

Air frying is the perfect way to cook many foods, but oven-baked goods are particularly good cooked in the air fryer. You always get crispy results and the food cooks much more quickly than in a conventional oven.

It is usually very easy to convert packet instruction and recipes from oven to air fryer. However, the time and the temperature both need to be adjusted:

  • Reduce the temperature by around 35°F/ 20°C
  • Reduce the cooking time by around 20%

You can use the air fryer calculator below to convert traditional oven recipes for the air fryer. This oven to air fryer conversion calculator includes options for Fahrenheit (°F) and Celsius (°C).

Remember, all air fryers are different and the exact time and temperature settings will depend on the make and model of air fryer, and the size of the ingredients, among other factors.


You can use this oven to air fryer converter as a guide for converting recipes. Remember to check on your food often during cooking, and use an instant read thermometer to check that it is cooked to the recommended safe temperature when cooking time is finished.

Tips for converting recipes for the air fryer

Preheating your air fryer

Recipes for the conventional oven almost always require preheating.

To preheat your air fryer, it is as easy as setting it to the desired temperature and turning it on for around 3 minutes. I normally just switch it on while I am preparing the ingredients.

Some brands of air fryers state that no preheating is required. However, I have found that I do usually get better results when cooking in a preheated air fryer if the cooking time is less than ten minutes.

Using oil

The action of the hot air when air frying helps food to crisp up more easily than when cooking in a regular oven. For this reason you can often get away with using less oil when roasting compared with what you would need for an oven.

I often spritz food with oil for air frying rather than coating it with oil as you might for a traditional roasting recipe.

You can check on the food halfway through cooking, and add an extra spritz of oil if it looks like it needs crisping up a bit more.

Don’t overcrowd the air fryer basket

Another difference between cooking in an air fryer and cooking in a conventional oven is that air fryers require air to be able to circulate freely around the food you are cooking.

For this reason, don’t overcrowd the basket. If the food is piled up, the remember to shake the food one or two times during cooking to redistribute the food and allow all surfaces to cook evenly.
