How to Convert Oven Recipes to Air Fryer
Convection ovens use a fan to circulate hot air evenly around food, which cooks faster and more evenly than a standard oven. Converting recipes is straightforward.
The basic rule:
- Reduce temperature by 25°F (about 15°C)
- Reduce cooking time by 25%
- Check food a few minutes early — convection ovens vary by model
This calculator applies these rules automatically and includes presets for common foods. Works with all convection oven brands and countertop convection ovens.

Frequently Asked Questions
How do I convert a standard oven recipe to convection?
Reduce the temperature by 25°F (about 15°C) and reduce the cooking time by about 25%. For example, if a recipe calls for 350°F for 40 minutes, use 325°F for about 30 minutes in a convection oven.
Why does a convection oven cook faster?
A convection oven has a fan that circulates hot air around the food. This eliminates hot and cold spots, delivers heat more efficiently to the food surface, and results in faster, more even cooking compared to a standard oven.
Should I always reduce both temperature and time?
Most bakers recommend reducing one or the other, not both. However, reducing temperature by 25°F and time by 25% works well for most savory dishes. For delicate baked goods, reduce only the temperature and keep the original time, checking early.
Do I need to preheat a convection oven?
Yes, preheat your convection oven just like a standard oven. Convection ovens may preheat slightly faster due to the fan, but always wait until it reaches the target temperature before placing food inside.
Is convection good for baking cookies and cakes?
Convection is excellent for cookies, giving them even browning. For cakes, use the convection setting cautiously — the moving air can create uneven rise in delicate batters. Reduce temperature only (not time) for cakes and check early.
Does this work for all convection oven brands?
Yes. The 25°F reduction and 25% time reduction is a universal guideline that works with all convection ovens including KitchenAid, GE, Bosch, Samsung, LG, and countertop models like Breville and Cuisinart.
