How to Convert Any Oven Recipe for an Air Fryer: The Ultimate Guide
Most recipes (printed on packaging, in cookbooks, on the back of seasoning packets) were written for conventional ovens. Air fryers cook hotter, faster, and with much more direct convection, so the published oven settings produce burnt outsides and cold middles. This guide is the conversion math, the corrections most guides skip, and the food-by-food adjustments, all sourced from manufacturer manuals and verified in our test kitchen.
While air fryers are essentially compact, high-powered convection ovens, you can’t just use the same settings. If you do, you’ll likely end up with something burnt on the outside and raw on the inside.
Why Do You Need to Convert?
The main difference between a conventional oven and an air fryer is air circulation. A traditional oven relies on radiant heat that slowly surrounds the food. An air fryer uses a powerful fan to circulate hot air rapidly around the food, a process known as convection.
This rapid air movement strips away moisture from the surface of the food much faster, creating that "fried" texture with significantly less oil. Because this process is so efficient, you must adjust both the temperature and the time.
Why this matters: skipping the conversion
If you take a 425°F / 20-minute oven setting and run it untouched in an air fryer, the typical outcome is a burnt exterior at the 7-minute mark while the interior is still icy or raw. The convection airflow strips moisture from the surface much faster than radiant oven heat does, which accelerates browning long before the food's interior has caught up.
The 25-25 rule exists because air fryers move heat to the food roughly 30-40% faster than a still-air oven and roughly 15-20% faster than a fan-assisted convection oven. Subtracting 25°F gives the interior more time to come up to temperature before the surface burns; reducing the time by about 20% accounts for the faster surface energy transfer. Skipping either correction is the single most common reason converted recipes fail.
How we tested these conversions
Every number on this page started as the manufacturer-published oven setting on actual packaging or in the appliance's published manual. The 25-25 conversion (subtract 25°F, reduce time 20-25%) is then applied as the baseline, and corrections for moisture, density, and surface area are layered on top. Those corrections are documented per food in the linked guides.
In-kitchen verification uses three machines: a Ninja AF101 (4-quart basket), a Cosori Pro II (5.8-quart basket), and a 30-inch GE convection oven for the reference oven runs. Internal temperatures are read with a calibrated ThermoWorks Thermapen ONE. We test a representative load (not a single piece) because batch size meaningfully changes recovery time.
Where a conversion came from a test run rather than a published manufacturer setting, the food-specific guide says so by name. We do not fold test-derived numbers and manufacturer-published numbers into the same line.
The Core Formula: The "25-25 Rule"
The most reliable industry standard for conversion is the 25-25 Rule.
- 1Reduce the Temperature: Subtract 25°F (or about 15°C) from the recommended oven temperature.
- 2Reduce the Time: Decrease the total cooking time by 25%.
Air Fryer Conversion Chart for Common Foods
| Food Item | Typical Oven Setting | Air Fryer Conversion |
|---|---|---|
| Chicken Wings | 400°F (35 mins) | 375°F (25-28 mins) |
| Frozen French Fries | 425°F (20 mins) | 400°F (12-15 mins) |
| Roasted Vegetables | 400°F (20 mins) | 375°F (10-12 mins) |
| Salmon Fillets | 400°F (15 mins) | 375°F (8-10 mins) |
| Pizza Rolls | 425°F (12 mins) | 390°F (6-8 mins) |
When the 25-25 rule doesn't work
The standard conversion fails for four predictable categories. Each one needs a different correction.
- Sweet potatoes and other high-sugar starches: subtract 30-40°F and reduce time by 30%, not 25%. Natural sugars caramelize and burn faster than starch browns.
- Sugary glazes (BBQ, teriyaki, honey-soy): apply the glaze in the last 3-4 minutes only, or it will scorch before the interior cooks. The base cook is at the standard 25-25 conversion; the glaze step is its own short pass.
- Rising-crust frozen pizza: drop only 15-20°F (not 25°F) and reduce time by about 30%. The crust needs lower temp for full rise, and the air fryer's airflow finishes it faster than the oven would.
- Bone-in cuts over 2 inches thick (large bone-in chicken, pork shoulder cubes): the 25-25 rule overshoots. The interior won't catch up before the surface burns. Drop 30°F and reduce time by only 10-15%, and verify with a thermometer.
When in doubt, the rule is: if the surface browns before the interior reaches the target internal temperature, the air fryer was too hot, not too long. Lower the temp 25°F more on the next attempt before changing the time.
5 Pro-Tips for Perfect Conversions
Don't Overcrowd the Basket: Air circulation is key. If you stack your food, it won't get crispy.
The "Shake" Factor: Pause halfway through and shake the basket for even browning.
Check Early: Air fryers vary by brand. Check your food 2-3 minutes before the timer ends.
Use a Meat Thermometer: Ensure chicken reaches an internal temperature of 165°F (74°C).
Oil is Still Your Friend: A light spray of oil helps the convection heat crisp the surface better.

Frequently Asked Questions
Can I put aluminum foil in an air fryer?
Yes, but ensure it is weighted down so it doesn't hit the heating element, and don't block all the airflow in the basket. Most manufacturer manuals (Ninja, Cosori, Instant) explicitly permit foil under food, not loose in the basket.
Do I need to preheat my air fryer?
Most air fryers reach target temperature in under 3 minutes. Preheating gives proteins like steak or salmon an initial sear, but for frozen foods and most baked items it makes no measurable difference. If a recipe calls for preheat, do it; if it doesn't, skip it.
Why is my air fryer smoking?
Almost always rendered fat hitting the heating element. A tablespoon of water in the bottom tray prevents grease from burning. If smoke continues with low-fat food, check for crumb buildup on the element. That is the most common cause of persistent smoking.
Does the conversion change for convection ovens?
Yes, but less. From a fan-assisted convection oven to an air fryer, subtract only 10-15°F and reduce time by 10%, not 20%. The convection oven already has airflow assistance, so the gap to the air fryer is smaller than from a still-air oven.
Can I convert baking recipes (cakes, cookies, brownies) the same way?
No. Baked goods need the standard 25°F drop but only a 10-15% time reduction, not 20%. Gluten and starch hydration need the full bake duration; cutting time too aggressively produces gummy centers. Verify doneness with a toothpick, not a timer.
Why is my air fryer cooking faster than the conversion suggests?
Three causes, in order of likelihood: (1) smaller chamber volume than our reference 5.8-quart, which concentrates heat, (2) higher wattage (1700W+ models run hot), (3) small batch size. A single serving cooks faster than the four-serving load these conversions are calibrated for. Always check 2-3 minutes early on a new recipe.
How does air fryer wattage affect the conversion?
1500W vs 1700W vs 1800W produces measurable differences: roughly 1 minute of cook time per 100W on a 4-quart basket. Manufacturer-published times in this guide assume the typical 1500 to 1700W range. If your appliance is at the high end, reduce time another 5-10% on the first cook.
Do these conversions work for the reverse direction (air fryer recipe to oven)?
The math is symmetric (add 25°F and increase time 20-25%), but baked goods need extra time on the oven side beyond that. We have a dedicated reverse calculator for the air-fryer-to-oven direction with worked examples.
