Oven to Air Fryer Conversion Chart
Use our quick reference temperature and cooking time conversion table for general baking guidelines.
This chart uses the common air fryer conversion rule: reduce oven temperature by about 25°F (15°C) and reduce cooking time by about 20%. Use the calculator above for food-specific adjustments.
Oven to Air Fryer Conversion Formula
Want to do the math yourself? You can use these standard formulas to convert conventional oven recipes into air fryer settings.
🌡️ Temperature Formula
Lower the oven temperature to account for the faster heat transfer of air fryer fans.
(For Celsius: reduce by 15°C)
⏱️ Cooking Time Formula
Reduce the cooking time since the circulating heat in an air fryer crisps and cooks food faster.
(A standard 20% time reduction)
How the Calculator Works
- Air fryers circulate hot air more aggressively than conventional ovens, cooking food faster.
- A general starting guideline is to lower the cooking temperature by 25°F (15°C) and reduce the cooking time by 20%.
- Different foods behave differently. Baked goods need a bigger time reduction, while frozen snacks may need slightly longer.
- This calculator factors in food category, thickness, and frozen status for a more accurate estimate.
When the Rule Does Not Apply
- Wet batters: Foods dipped in wet batter (like onion rings) need a deep-fryer or specialized coating; they will drip through an air fryer basket.
- Very large roasts: A whole turkey or massive beef roast will block airflow and cook unevenly compared to an oven.
- Crowded baskets: If you stack fries or food in multiple layers, the steam will prevent crisping. You must shake the basket frequently.
Common Oven to Air Fryer Conversion Examples
Frequently Asked Questions
How do I convert oven time to air fryer time?
A common starting point is to reduce the oven cooking time by about 20%. For example, a 30-minute oven recipe usually becomes about 24 minutes in an air fryer. Check food early because air fryer models vary.
Do I need to lower the temperature for an air fryer?
Yes. A common rule is to lower the oven temperature by about 25°F, or about 15°C, when converting to air fryer cooking.
What is 400°F in an air fryer?
If an oven recipe calls for 400°F, a good air fryer starting point is about 375°F (190°C).
What is 350°F in an air fryer?
If an oven recipe calls for 350°F, start with about 325°F (160°C) in the air fryer.
Can I convert frozen food oven instructions to air fryer instructions?
Yes, but frozen food may need slightly more time than fresh food. Start with the calculator result, shake or flip halfway through, and check early.
Is the oven to air fryer conversion rule always accurate?
No. It is a starting point. Food thickness, basket size, air fryer model, and how crowded the basket is can all change the final cooking time.
Do I need to preheat my air fryer?
Most air fryers heat up extremely fast (within 2–3 minutes), so preheating isn't always necessary but it helps get a more even and crispy result, especially for meats and baked goods. If you don't preheat, you might need to add 1–2 minutes to the cooking time.
Can I use aluminum foil or parchment paper in an air fryer?
Yes, you can use aluminum foil or parchment paper, but make sure it is weighed down by the food so it doesn't get sucked into the heating element. Never preheat the air fryer with loose paper or foil.
Do I need to use oil in the air fryer?
You need much less oil than frying or conventional baking. A light spray of oil (like olive or canola oil) on vegetables or fresh meats will help them brown and crisp up beautifully, but frozen pre-fried foods do not need any extra oil.
