How To Convert Recipes To Air Fryer | Simple Temp Trick

Convert an oven recipe to an air fryer by lowering the temperature 25°F (15°C) and cutting the cooking time by roughly 20–25%.

You pull out a favorite recipe—roasted vegetables, baked chicken thighs, maybe a casserole—and see the oil temperature and time written for a conventional oven. Your air fryer promises faster cooking, but guessing the adjustments can leave you with burnt outsides and raw centers.

The good news is that converting most oven recipes follows a simple pattern: reduce the temperature by about 25°F and shorten the cooking time by roughly 20–25%. The exact numbers shift depending on your air fryer model, food density, and batch size, but this rule works across a wide range of dishes. Here’s how to apply it without trial-and-error.

The Basic Conversion Rule That Works Most of the Time

Air fryers cook faster than conventional ovens because they blast high-speed air around the food, transferring heat more efficiently. That means you need less heat and less time to reach the same internal doneness and browning.

Most cooking guides agree on a starting point: reduce the oven temperature by 25°F (or about 15°C) and cut the total cooking time by 20–25%. For example, a chicken breast that bakes at 375°F for 30 minutes in a regular oven can go in the air fryer at 350°F and be done around 22–24 minutes.

This “25/20” rule won’t be perfect every time, but it gets you close enough to check and adjust. If the food needs more time, add two to three minutes and recheck.

Why Different Air Fryers Give Different Results

Not all air fryers perform identically. The wattage, basket size, and fan design affect how quickly food cooks. That’s why your friend’s conversion might come out perfect while yours needs tweaking.

  • Basket size and food quantity: A crowded basket traps steam and slows browning. Leave room around each piece, and cook in batches if needed.
  • Model power (wattage): High-wattage machines (1700W+) cook faster than lower-wattage ones. Drop time by 25% on high-power units, 20% on lower-power ones.
  • Frozen vs. room-temperature food: Frozen items need slightly longer time, but the same temperature reduction works. Check a few minutes earlier than the converted time.
  • Bone-in or thick cuts: Dense proteins take longer to reach the center. Use a meat thermometer to confirm doneness rather than trusting time alone.
  • Preheating habits: Some recipes assume you start cold. If your recipe calls for preheating, factor that into your time adjustment.

Treat the conversion rule as a starting point, then adjust based on what you see and smell after the first try.

Temperature and Time Adjustments You Can Count On

To make the rule concrete, here are common oven temperatures and their air fryer counterparts. These numbers come from the same conversion guidelines shared across recipe sites, including Allrecipes’ reduce temperature by 25 degrees guide.

Oven Temperature Air Fryer Temperature Time Reduction
350°F (175°C) 325°F (165°C) ~20–25%
375°F (190°C) 350°F (175°C) ~20–25%
400°F (200°C) 375°F (190°C) ~25%
425°F (220°C) 400°F (200°C) ~20–25%
450°F (230°C) 425°F (220°C) ~25%

These conversions assume a single layer of food and an average 1500W air fryer. If you’re adapting a recipe from a convection oven rather than a conventional oven, the adjustment may be smaller—try reducing only 10–15°F and cutting time by 15%.

Step-by-Step: Converting Any Oven Recipe

Follow this process for any standard oven recipe. It works for meats, vegetables, frozen convenience foods, and most baked items.

  1. Write down the original temperature and time. You’ll need both numbers to calculate your starting point.
  2. Reduce the temperature by 25°F (or 15°C). For particularly delicate items like cakes or breaded fish, you can reduce by 30–40°F.
  3. Cut the original cooking time by 20–25%. Multiply the minutes by 0.75 to get your first check time. For a 40‑minute recipe, check at 30 minutes.
  4. Arrange food in a single layer. Overcrowding traps steam and extends cooking time. If you need to do two batches, split the total.
  5. Shake or flip halfway through. This ensures even browning. Use tongs or a spatula—avoid scraping nonstick coatings.

After the first check, add two to three minutes if needed. Most recipes brown faster than the oven version, so doneness often arrives sooner than you expect.

Handling Frozen Foods and Baking in the Air Fryer

Frozen foods with oven instructions follow the same conversion rule. Reduce the package temperature by 25°F and start checking about 20% earlier. The food will defrost and cook in the same cycle, so no thawing necessary.

Baking in an air fryer works for small batches of muffins, cookies, and even quick breads. The reduce temperature 25 to 50 approach is common for baked goods, but start with the lower end to avoid overbrowning. Cover the top loosely with foil if the crust finishes before the center sets.

Food Type Oven Temp Air Fryer Temp Notes
Frozen chicken nuggets 400°F 375°F Shake halfway; check 2 min early
Baked chicken breast 375°F 350°F Use thermometer; internal 165°F
Sheet pan vegetables 425°F 400°F Toss with oil; check at 10 min

If you’re baking something that relies on rise (like cake), use a pan that fits inside the basket and reduce temperature by 30–40°F to give the center time to cook without burning the outside.

The Bottom Line

Converting an oven recipe to an air fryer doesn’t require a calculator—just remember to drop the temperature by about 25°F and shorten the cooking time by roughly a quarter. Check early, adjust as you go, and note what worked for next time. The rule gets more accurate with practice.

Your air fryer’s power and basket size matter more than the exact numbers, so treat the 25/20 guideline as a smart starting point. For a special recipe you can’t afford to ruin, run a small test batch first. If the results are consistently off, tweak by 5–10°F or a couple of minutes until it feels right for your setup.
