How to Convert Oven Cooking Time to Air Fryer Time

An air fryer is a compact convection oven. Its small chamber and powerful fan surround food with fast-moving hot air, so it cooks faster than a full-size oven and you almost always need less time as well as a lower temperature. Converting the cooking time is the step people forget most often — and it is the difference between crisp, golden food and something dried out or burnt.

The Simple Time Rule

For most recipes, reduce the oven cooking time by about 20% (multiply by 0.8) and lower the temperature by 25°F (about 15°C). So a dish that bakes for 30 minutes in the oven takes roughly 24 minutes in the air fryer at 25 degrees lower. The calculator above does this math for you and adjusts for different foods.

Why Air Fryers Cook Faster

In a conventional oven, hot air rises slowly and a large cavity takes time to heat food evenly. An air fryer's tight basket and high-speed fan blast the surface of the food from every direction at once. That concentrated airflow transfers heat much more efficiently, cooking the outside quickly and crisping it — which is why the same food is done sooner and at a lower dial setting.

Always Check Early the First Time

Because air fryer models vary in wattage and basket size, treat the converted time as a starting point. Check the food a few minutes before the calculated time the first time you make a recipe, then note what worked so next time is exact. It is much easier to add two minutes than to rescue something overcooked.

Adjust for the Food

Thin or small items — vegetables, fries, shrimp — cook proportionally faster and benefit from the full 20% reduction. Dense or thick items like a whole chicken or a loaf of banana bread give up less time, since the heat still needs to reach the center. Delicate baked goods should be watched closely because the air fryer's direct airflow can brown the top before the middle is set. The calculator applies a different time factor for each food category to account for this.

A Worked Example: 30 Minutes in the Oven

Say a recipe calls for baking at 200°C (400°F) for 30 minutes in a conventional oven and you want to use the air fryer instead. Apply the rule: drop the temperature 25°F to about 375°F (or 180°C), and cut the time by roughly 20% — 30 minutes becomes about 24 minutes. Set a timer for 24 minutes but open the basket at the 20-minute mark to check, shaking or flipping the food so it browns evenly. If it needs a little longer, add two minutes at a time. This same method works for any starting time: a 45-minute oven roast becomes about 36 minutes, and a quick 15-minute bake becomes about 12.

Common Mistakes When Converting Cooking Time

• Keeping the full oven time — the number-one cause of burnt or dried-out air fryer food. Always cut the time about 20%.
• Lowering the time but not the temperature — both change together. Drop the dial 25°F so the outside doesn't scorch before the inside cooks.
• Overcrowding the basket — piling food in defeats the airflow and makes everything cook slower and unevenly. Work in a single layer, in batches if needed.
• Never checking early — every air fryer runs a little differently. Peek a few minutes before the timer the first time you make a dish.
• Forgetting to shake or flip — the basket cooks from the top and sides most; turning food halfway keeps browning even.

Frequently Asked Questions

How much less time does an air fryer take than an oven?

About 20% less. Air fryers cook faster because their concentrated fan-forced heat surrounds the food, so a good rule is to multiply the oven time by 0.8. A 25-minute oven recipe takes roughly 20 minutes in the air fryer, and a 30-minute recipe takes about 24 minutes.

What is 30 minutes in the oven in an air fryer?

About 24 minutes. Reduce the cooking time by 20% and lower the temperature 25°F (15°C). So 400°F for 30 minutes in the oven becomes roughly 375°F for 24 minutes in the air fryer. Check a few minutes early the first time.

Do I lower the temperature and the time?

Yes — both. When moving a recipe from the oven to the air fryer, drop the temperature by 25°F (about 15°C) and reduce the cooking time by about 20%. Changing only one usually leaves food overcooked outside or underdone inside.

How do I convert oven baking time to air fryer time?

Multiply the oven time by 0.8 to get the air fryer time, and lower the temperature 25°F. Baked goods are the exception — they give up a little less time and should be watched closely, since the air fryer's direct airflow can brown the top quickly. Use the calculator above and choose "Baked Goods" for an adjusted estimate.

Why is my air fryer food overcooked?

Most likely you used the full oven time. Air fryers cook about 20% faster, so leaving food in for the oven's cooking time overcooks it. Cut the time by a fifth, lower the temperature 25°F, and check early until you learn how your specific model behaves.

Does the air fryer time change for frozen food?

Frozen foods already have package instructions written for an oven, so apply the same rule: reduce the time about 15–20% and lower the temperature 25°F. Spread pieces in a single layer, shake the basket halfway, and they will crisp better than they do on an oven tray.
