You found the perfect recipe — but it was written for a conventional oven, and you want to make it in your air fryer. Good news: the conversion is simple and consistent. Better news: the result is usually crispier and faster.
The Standard Conversion Rule
Two adjustments, applied together:
- Reduce temperature by 25°F (about 15°C)
- Reduce cooking time by 20–25%
A recipe calling for 400°F for 30 minutes becomes 375°F for 22–24 minutes in an air fryer. That's it for most recipes.
Why Air Fryers Cook Faster
A conventional oven heats air slowly by radiation from heating elements. An air fryer is essentially a compact convection oven — a powerful fan circulates hot air rapidly around the food. This convection dramatically speeds up heat transfer, cooking food more evenly and significantly faster. The smaller chamber also reaches temperature almost instantly, versus a conventional oven's 10–15 minute preheat.
💡 Don't overcrowd the basket. The air fryer's advantage comes from hot air circulating completely around food. Stacking or overcrowding blocks airflow and produces uneven, less crispy results. Cook in batches if needed — the speed advantage means it's still faster overall.
Foods That Air Fry Exceptionally Well
- Frozen foods (fries, nuggets, fish sticks) — crispier than oven, faster
- Chicken thighs and wings — skin gets genuinely crispy without deep frying
- Vegetables — roast in half the time with better caramelization
- Reheating pizza and fried foods — restores crispness that microwaving destroys
- Bacon — less splatter, crisper result
Foods That Don't Air Fry Well
- Wet batters (beer batter, pancake batter) — drip through the basket before setting
- Large roasts — most air fryers are too small; heat doesn't penetrate evenly
- Leafy greens — the fan blows them around the basket
- Cheese-heavy dishes — cheese melts into the basket before the food is done
Check Early, Every Time
Air fryer performance varies significantly by model — a 5-quart basket air fryer cooks differently than a 10-quart toaster oven-style. Use the time conversion as a starting point, then check your food 3–5 minutes before the calculated time. Most experienced air fryer cooks develop a feel for their specific appliance within a few uses.
