Air Fryer Calculator
Convert oven recipes to air fryer times and temperatures. Get perfect air fryer settings for any food.
Formula
Air Fryer Temp = Oven Temp - 25°F, Time = Time × 0.8
This Air Fryer Calculator computes results from your provided inputs using the calculator's underlying model.
Worked Examples
Example 1: Oven Recipe to Air Fryer (General Food)
Problem:A recipe says bake at 425 F for 30 minutes. Convert it to air fryer settings using the General food type.
Solution:Temperature: 425 - 25 = 400 F. Time: 30 x 0.8 = 24 minutes. The General food type applies no further change (temperature modifier 0 F, time multiplier 1.0). Because the target is 400 F or higher, allow a 5 minute preheat. Shake count: floor(24 / 5) = 4 shakes.
Result:400 F for 24 minutes, 5 minute preheat, shake 4 times
Example 2: Roasted Vegetables With the Vegetables Adjustment
Problem:Sheet-pan vegetables call for 400 F for 25 minutes in a conventional oven. What are the air fryer settings?
Solution:Base conversion: 400 - 25 = 375 F and 25 x 0.8 = 20 minutes. The Vegetables food type then subtracts 10 F and multiplies time by 0.85: Temperature: 375 - 10 = 365 F. Time: 20 x 0.85 = 17 minutes. Below 400 F, so a 3 minute preheat is enough. Shake count: floor(17 / 5) = 3 shakes.
Result:365 F for 17 minutes, 3 minute preheat, shake 3 times
Frequently Asked Questions
How do I convert an oven recipe to air fryer settings?
Start by cutting the oven temperature by 25 F and the cooking time by about 20 percent, which is what Air Fryer Calculator does before applying any food-specific adjustment. Air fryers move hot air far more aggressively than a conventional oven, so both the surface browning and the interior cooking run ahead of schedule. Check the food several minutes early until you learn how your particular model behaves.
Do I need to preheat an air fryer before cooking?
Preheating for 3 to 5 minutes gives a noticeably crisper exterior because the food hits an already hot surface and starts browning immediately. It matters most for frozen foods, breaded items and anything cooked at 400 F or above. For long cooks of 25 minutes or more the difference is small, so you can load a cold basket and add a couple of minutes instead.
Why shake the air fryer basket during cooking?
An air fryer cooks by blowing hot air past the food, so whatever touches the basket floor or sits underneath other pieces browns more slowly. Shaking or tossing every 5 to 7 minutes redistributes the pieces so every surface gets exposed to the airflow. It matters most for fries, cubed vegetables, wings and anything stacked more than one layer deep.
Why reduce the oven temperature by 25 F for an air fryer?
An air fryer is a small convection oven with a powerful fan in a tight chamber, so heat transfer to the food surface is much faster than in a conventional oven at the same setting. Dropping the dial by about 25 F compensates, letting the interior reach doneness before the exterior scorches. Fan ovens use the same 25 F rule for the same reason.
How full can I load an air fryer basket without ruining the result?
Keep food to a single layer with visible gaps, filling no more than about two thirds of the basket by volume. Overcrowding blocks the airflow that does the cooking, so moisture stays trapped and the food steams instead of crisping. Cooking two smaller batches almost always finishes faster overall than forcing one overloaded batch and adding minutes.
Do frozen foods need different air fryer settings?
Frozen items go straight in with no thawing, but preheat the air fryer for 3 to 5 minutes first so the surface sears rather than slowly defrosts. Follow the package air fryer instructions where they exist; where they do not, apply the same 25 F reduction to the oven figure but keep the full time, then check about two thirds of the way through.
How much oil should I use in an air fryer?
One to two teaspoons tossed through a full basket is usually enough, and many breaded or naturally fatty foods need none at all. Oil in an air fryer is for browning and flavour, not for heat transfer. Use a pump sprayer or toss in a bowl rather than an aerosol can, since the propellants and additives in aerosol sprays can damage the non-stick basket coating.
Why does food come out soggy instead of crisp in the air fryer?
The three usual causes are an overcrowded basket, wet food surfaces, and skipping the preheat. Pat food dry before it goes in, leave gaps between pieces, and preheat for 3 to 5 minutes when the target is 400 F or above. Wet batters do not work at all in an air fryer because there is no hot oil to set them; they drip through the basket.
What internal temperatures should I check after air frying?
Converted times are estimates, so verify with an instant-read thermometer. USDA safe minimum internal temperatures are 165 F for all poultry, 160 F for ground beef and pork, and 145 F with a three minute rest for whole cuts of beef, pork, lamb and fish. Check the thickest part away from bone, and add a couple of minutes if the reading is short.
Does an air fryer use less electricity than a full oven?
Usually yes, mainly because the chamber is small and preheats in minutes rather than 10 to 15. A typical 1,500 W air fryer running 20 minutes uses 0.50 kWh, while a 2,400 W oven running 45 minutes including preheat uses 1.8 kWh. At 16 cents per kWh that is about 8 cents against 29 cents for the same meal.
