Converting your favorite oven recipes to air fryer is easier than you think. With a simple formula and the right technique, you'll be recreating all your beloved dishes in your air fryer within minutes. This guide walks you through everything you need to know.
Write down the oven temperature and cooking time from your recipe. For example: "Bake at 400°F for 30 minutes." Note the food type (meat, vegetables, baked goods) as different items may need slight adjustments.
Subtract 25°F from the oven temperature. This is the magic number for most recipes.
Example: 400°F (oven) − 25°F = 375°F (air fryer)
Exception: For delicate foods like baked goods or fish, try reducing only 15–20°F first.
Multiply the original time by 0.8 (which removes 20% of the time).
Example: 30 minutes × 0.8 = 24 minutes
Or simply subtract 20%: 30 minutes − 6 minutes = 24 minutes.
Pat food dry with paper towels — moisture prevents browning. Apply a light coating of oil (spray or brush) for better crisping. Season generously with salt, pepper, and your preferred spices. Cut food into similar-sized pieces for even cooking.
Place food in a single layer without overlapping — this ensures air circulation. Don't overcrowd the basket; if needed, cook in multiple batches. For smaller items, use a perforated basket or tray to prevent items from falling through vents.
Most recipes benefit from a 3–5 minute preheat at your converted temperature. This ensures even cooking from the start, especially for delicate proteins. Follow your model's guidance for preheat indicators.
Set your converted time and temperature. At the halfway point, shake the basket or flip the food for even browning. Check doneness 2–3 minutes before the converted time ends and adjust as needed.
For meat: Use a meat thermometer — chicken 165°F, ground meat 160°F, beef 145°F.
For vegetables: Fork-tender is the goal.
For baked goods: A toothpick inserted should come out clean.
Add 2–3 minutes more cooking time if needed, then recheck.
| Food | Oven Temp | Air Fryer Temp | Oven Time | Air Fryer Time |
|---|---|---|---|---|
| Chicken Breast | 400°F | 375°F | 25 min | 20 min |
| Roasted Vegetables | 400°F | 375°F | 20 min | 16 min |
| Frozen Fish Fillets | 400°F | 375°F | 15 min | 12 min |

The 25°F rule works for most foods, but delicate items like fish or baked goods may only need 15°F reduction. Start conservative and adjust based on results.
Overcrowding the basket blocks air circulation. Always arrange food in a single layer and shake or flip halfway through cooking.
Baking is trickier because it's chemistry-based. Use a 15°F reduction and watch carefully. Many baked goods work better with air fryer-specific recipes.
Preheating (3–5 minutes) helps with even cooking, but frozen foods and some vegetables don't require it. Check your recipe needs.
Reduce the temperature by another 25°F and add time. Some foods may need to be arranged further apart or in a single layer only.
