Tips
- •Preheat the air fryer for 3-5 minutes before cooking.
- •Do not overcrowd the basket — leave space for air circulation.
- •Shake the basket or flip food halfway through cooking.
- •Lightly spray food with oil for extra crispiness.
How air fryer conversion works
Air fryers cook food by rapidly circulating hot air around it in a compact chamber. This concentrated convection effect means food cooks faster and crisps up better than in a traditional oven — without needing as much oil.
The basic rule: reduce temperature by 25°F and time by 20%. If your oven recipe says 400°F for 30 minutes, set your air fryer to 375°F for about 24 minutes. This works for most recipes, but always check food a few minutes early until you know your specific air fryer.
Every air fryer is slightly different. Basket-style air fryers tend to cook faster than oven-style ones. Wattage matters too — a 1700W air fryer will cook faster than a 1400W model. Use these conversions as a starting point and adjust based on your results.
The golden rule: do not overcrowd. Air fryers need space for air to circulate. A single layer with gaps between pieces gives you the best crispiness. If you need to cook a large batch, do it in rounds.
This calculator also supports conversions to and from Instant Pot (pressure cooker) and slow cooker. These are approximate — pressure cooking and slow cooking use fundamentally different methods than dry heat, so not all recipes translate perfectly.
Frequently asked questions
How do I convert oven temperature to air fryer?▾
Reduce the oven temperature by 25°F (about 15°C) and reduce the cooking time by about 20%. For example, if a recipe calls for 400°F for 30 minutes in the oven, set your air fryer to 375°F for about 24 minutes.
Do I need to preheat my air fryer?▾
Yes, preheating your air fryer for 3-5 minutes helps achieve better results, especially for foods that need a crispy exterior. Some newer models preheat automatically.
Can I convert slow cooker recipes to air fryer?▾
Some slow cooker recipes can be adapted for the air fryer, but not all. Braised meats and stews are better suited for slow cooking. Foods that benefit from dry heat and crispiness — like chicken, vegetables, and frozen foods — convert well to air fryer.
Why does my air fryer cook faster than an oven?▾
Air fryers use rapid air circulation (convection) in a compact space, which transfers heat more efficiently than a full-size oven. The smaller cooking chamber means less air to heat and faster cooking times — typically 20-25% faster.
What is the difference between air fryer and convection oven?▾
Both use fans to circulate hot air, but air fryers have a more compact chamber and stronger airflow, making them slightly faster and crispier. Convection ovens offer more space for larger batches. Temperature and time settings are very similar between the two.
