Master oven to air fryer conversion with our complete guide. Includes temperature and time conversion charts for all food types.
The Basic Conversion Rule
The fundamental rule for converting oven recipes to air fryer is: reduce the temperature by 25°F and reduce the cooking time by 20%. For example, if an oven recipe calls for 400°F for 30 minutes, set your air fryer to 375°F and check for doneness around 24 minutes.
Why the Conversion Works
Air fryers are essentially small, powerful convection ovens. Their compact size means heat reaches food faster and more intensely. The high-speed air circulation removes moisture from food surfaces more efficiently, promoting faster browning and crisping.
Food-Specific Adjustments
Different food types need different adjustments. Meat typically needs a 15% time reduction (it needs a gentler cook). Vegetables can handle a 25% reduction. Frozen foods need about 18% less time. Baked goods need the oven temperature reduced by 30°F and time by 22%.
Frequently Asked Questions
Does the 25°F temperature rule always apply?
It's a reliable starting point, but some foods benefit from different adjustments. Baked goods, for instance, do better with a 30°F reduction. Use the basic rule and adjust based on your results.
Why is my food not crispy in the air fryer?
The most common culprits are overcrowding the basket, not preheating, and skipping the oil spray. A light coating of oil and adequate airflow are essential for crispiness.
