Understanding the 25 Rule for Air Fryers
Definition and Origin of the 25 Rule
So, what exactly is this 25 rule? It’s a simple guideline that suggests reducing the oven cooking temperature by 25°F and shortening the cooking time by 25% when shifting recipes to the air fryer.

This formula works great with many dishes. However, keep in mind that your particular air fryer might have its quirks, similar to how every oven heats a bit differently. For more insight on how air fryers work, dive into some detailed readings—they’re invaluable.

If things look like they’re browning too fast, lower the temperature slightly or reduce time further. Learning your air fryer’s temperament is part science, part art. And for safety, always check the safe minimum internal temperature to ensure delicious and safe meals.
