How do I convert an air fryer recipe to a conventional oven?

To convert an air fryer recipe to a conventional oven: (1) Increase the cooking temperature by 25°F (approx. 15°C), and (2) Increase the cooking time by 20% to 30% (multiply air fryer minutes by 1.25). For example, a recipe calling for 375°F for 15 minutes in an air fryer converts to 400°F for roughly 18 to 20 minutes in a standard oven.

Why do air fryers cook faster than conventional ovens?

An air fryer is a concentrated convection cooker. It circulates high-velocity hot air in a compact chamber directly surrounding the food, which rapidly strips away the moisture barrier (the boundary layer) and transfers thermal energy 20% to 35% faster than a large, radiant conventional oven.

How can I get air-fryer-style crispiness in a regular oven?

To replicate air fryer crispiness in an oven, elevate your food on a wire baking rack set inside a rimmed baking sheet. This allows hot oven air to circulate underneath the food, preventing it from steaming in its own rendered juices.

What is the 25/20 rule for air fryers?

The 25/20 rule states that when converting from a standard oven to an air fryer, you reduce the temperature by 25°F and reduce the cooking time by 20%. Conversely, when converting from an air fryer to an oven, you add 25°F and add 20% to 25% to the cooking time.

For optimal crispiness in a conventional oven, place food on a raised wire rack inside a rimmed baking sheet. This allows heat to circulate underneath 360°, mimicking an air fryer basket.

🔥 The Culinary 25° / 20% Rule

Air fryers cook with high-velocity forced convection in a small cavity. When moving to a full-sized radiant oven, adding +25°F (+15°C) and +20% to +30% time compensates for the larger oven cavity and slower airflow.

Frequently Asked Questions

Mastering heat conversion between air fryers and ovens.

How do I convert an air fryer recipe to a regular oven? ↓

To cook an air fryer recipe in a standard oven, you must account for the larger cavity and lack of forced air. The golden rule is: Increase the temperature by 25°F (15°C) and increase the cooking time by 20% to 30%. For example, if an air fryer recipe specifies 375°F for 15 minutes, set your oven to 400°F and bake for 18 to 20 minutes.

Do I need to preheat a conventional oven when converting from an air fryer? ↓

Yes! While small air fryers reach cooking temperature in 2 to 3 minutes, conventional ovens require 10 to 15 minutes to fully preheat. Never put your food into an unheated oven; wait until the preheat indicator chimes so your cooking time calculation remains accurate.

How do I get foods as crispy in the oven as in an air fryer? ↓

The secret is air circulation under the food. Place a stainless steel wire cooling rack on top of your baking sheet and arrange your food on the rack. This elevates the food off the pan, allowing hot air to circulate underneath and preventing sogginess from trapped steam. Lightly spraying food with high-smoke-point oil (avocado or canola oil) also promotes a crispy golden crust.

What if my oven has a "Convection Bake" setting? ↓

If using a full-sized convection oven (with a convection fan turned on), keep the temperature the same as the air fryer recipe (or increase by just 10°F), and increase the cooking time by only 10% to 15% to compensate for the larger oven cavity.
