The fundamental rule for converting any oven recipe to an air fryer is simple: reduce the temperature by 25°F (about 15°C) and reduce the cooking time by 20–25%. Air fryers cook faster because they circulate hot air rapidly in a compact space, creating intense convection that transfers heat to food more efficiently than a conventional oven.
A conventional oven heats a large cavity and relies partly on radiant heat from the elements. An air fryer uses a high-speed fan to move superheated air around food in a small chamber. This creates a convection effect that is 2–3× more intense than a standard convection oven. The result: faster cooking, crispier exteriors, and more even browning — with less preheating time and lower energy use.
Baked goods and casseroles: Reduce by 25°F and check 3-4 minutes early. Proteins (chicken, fish, steak): Reduce by 25°F, cut time by 20%. Frozen foods: Reduce by 25°F, cut time by 25-30% — these benefit most from the concentrated heat. Vegetables: Reduce by 25°F, cut time by 20%. Shake the basket halfway through for even crisping.
Don't overcrowd the basket. Air needs to circulate around food. A single layer with small gaps produces the crispiest results. Cook in batches if needed. Use a light oil spray on foods that would normally be baked dry — it promotes browning. Flip or shake midway through cooking for even results. Check early. Until you learn your specific air fryer's personality, check food at the 75% mark of the converted time.
Wet batters (tempura, beer batter) will drip through the basket. Use dry breadcrumb coatings instead. Very large items that don't fit with clearance around them will cook unevenly. Leafy greens get blown around by the fan. Cheese-topped dishes can work but may need a lower temperature to avoid burning the top before the base heats through.
Air fryers use significantly less energy than conventional ovens. A typical air fryer draws 1,400–1,700 watts and runs for shorter periods, while a full-size oven draws 2,000–5,000 watts and takes longer to preheat and cook. For small to medium portions, an air fryer can cut cooking energy costs by 50–70% compared to a full-size oven.
| Oven Temp (°F) | Air Fryer Temp (°F) | Oven Time | Air Fryer Time |
|---|---|---|---|
| 350°F | 325°F | 30 min | 22–25 min |
| 375°F | 350°F | 25 min | 18–22 min |
| 400°F | 375°F | 20 min | 15–18 min |
| 425°F | 400°F | 15 min | 11–14 min |
| 450°F | 425°F | 12 min | 9–11 min |
An air fryer is essentially a compact convection oven with a powerful fan that circulates superheated air at high velocity around food placed in a perforated basket. The key differences from conventional ovens are the smaller cooking chamber (which concentrates heat), the more powerful fan (which creates faster air circulation), and the perforated basket (which allows hot air to contact food from all sides simultaneously). These three factors combine to produce cooking results that approximate deep frying — crispy exterior with moist interior — using little or no added oil. The rapid air circulation also means air fryers preheat in 2-3 minutes versus 10-15 minutes for conventional ovens, reducing total cooking time significantly.
The general conversion rule from conventional oven to air fryer is to reduce temperature by 25°F (about 15°C) and reduce cooking time by 20-25%. A recipe calling for 400°F for 25 minutes in a conventional oven translates to approximately 375°F for 18-20 minutes in an air fryer. However, these conversions are starting points, not guarantees — air fryer models vary significantly in heating element power (800-1800 watts), fan speed, basket size, and cooking chamber geometry. Basket-style air fryers (where food sits in a pull-out drawer) cook differently from oven-style air fryers (which have racks like a toaster oven), and both differ from paddle-style air fryers that automatically stir food during cooking.
Protein-heavy foods (chicken, fish, steak) generally need less temperature reduction but more time reduction because the high-velocity air sears the surface quickly. Chicken thighs at 375°F for 20-22 minutes in an air fryer (versus 400°F for 30-35 minutes in a conventional oven) develop a crispy skin while remaining juicy inside. Vegetables need the full 25°F reduction and benefit from a light coating of oil to prevent drying — broccoli, Brussels sprouts, and cauliflower at 375°F for 10-12 minutes produce caramelized edges impossible to achieve in a microwave and difficult in a conventional oven without longer cooking times.
Baked goods require the most careful conversion because air fryer fans can blow batter, create uneven tops, and overcook exteriors before interiors set. Reduce temperature by 25-30°F and reduce time by 20-30%. Muffins and cupcakes work well at 325°F for 10-12 minutes. Cookies need 325°F for 5-7 minutes but must be watched carefully. Breads and cakes larger than 6 inches in diameter often cook unevenly in air fryers because the small chamber creates hot spots. For best results with baked goods, use dark, non-stick pans that fit inside the basket with at least 1 inch of clearance on all sides for air circulation, and check doneness 3-5 minutes before the converted time suggests they should be done.
The most critical factor in air fryer cooking that conversion charts cannot capture is food crowding. Air fryers work by circulating hot air around every surface of the food — overcrowding blocks airflow and turns crispy air-frying into steaming. The general rule is to fill the basket no more than halfway for items that need crispiness (fries, wings, breaded items) and no more than two-thirds for items where browning is less critical (vegetables, reheating). A 5.8-quart air fryer basket comfortably holds about one pound of french fries in a single layer. Doubling the amount means cooking in two batches of 12 minutes each (24 minutes total) rather than one crowded batch of 20 minutes that produces limp, unevenly cooked fries.
Shaking or flipping food halfway through cooking ensures even browning. Unlike a conventional oven where food sits on a flat sheet and browns from radiant heat above, air fryers brown from all directions simultaneously — but the side resting against the basket receives less airflow. Flipping chicken pieces, shaking fries, and rearranging vegetables at the midpoint produces significantly more even results. Some air fryer models include automatic shake reminders at the halfway point, and paddle-style models handle this automatically, though they sacrifice the ability to cook delicate items that would break apart with stirring.
Air fryers excel at foods that benefit from high, dry heat and rapid surface dehydration — essentially the same foods that perform well in deep fryers or on convection roast settings. Frozen foods designed for oven cooking (chicken nuggets, fish sticks, tater tots, pizza rolls) perform exceptionally well because air fryers heat faster and circulate air more aggressively than conventional ovens, producing crispier results in less time. Fresh proteins with skin or breading (chicken wings, bone-in thighs, breaded cutlets) develop superior crusts because the intense airflow rapidly evaporates surface moisture. Root vegetables (potatoes, sweet potatoes, carrots, beets) caramelize beautifully when cut into uniform pieces and tossed with a tablespoon of oil.
Foods that perform poorly in air fryers include anything with a wet batter (tempura, beer-battered fish) because the batter drips through the basket before it sets, lean proteins without coating (boneless skinless chicken breast dries out easily without the protective layer of skin or breading), and delicate items like fish fillets that may break apart in the air current. Large roasts do not fit most air fryer baskets and cook unevenly due to the small cooking chamber. Cheese-topped dishes can work but require monitoring — the intense top heat melts and browns cheese very quickly, transitioning from golden to burnt in under a minute.

→ General rule: reduce temp by 25°F and time by 20%. A recipe calling for 400°F for 20 minutes becomes roughly 375°F for 15–16 minutes in an air fryer. This works for most foods.
→ Check food halfway through. Air fryers vary by brand and size. Check for doneness at 75% of calculated time and adjust. A meat thermometer is your best friend for proteins.
→ Don't overcrowd the basket. Air fryers work by circulating hot air. Overcrowding blocks airflow and creates steaming instead of crisping. Cook in batches for best results.
→ Preheat for crispier results. Like a conventional oven, preheating for 3–5 minutes gives better browning on the first batch. See our Cooking Converter for unit conversions.
