How to adjust air fryer time for bigger batches
Recipe times are for the “base amount.” If 10 dumplings take 12 minutes, how long do 20 take? Not 24.
Why double the food isn’t double the time
An air fryer cooks by blowing hot air over the surface of the food. As long as pieces don’t overlap, each one gets about the same airflow. So more food only adds a little time.
Time jumps when food overlaps. The covered surfaces get no airflow, and by the time they cook, the exposed surfaces have burnt.
If it overlaps, cook in batches
When the food covers the whole basket floor, split it into two batches. You’ll get better results, and the total time is about the same or shorter than one crowded batch.
How this site’s calculator works
The “Cooking more or less?” calculator on each recipe estimates:
- Estimated time = base time × √(your amount ÷ base amount)
- The result never goes below 0.7× or above 1.6× the base time.
For example, if 10 dumplings take 12 minutes, 20 take about 12 × √2 ≈ 17 minutes. Even 40 stop at 19 minutes (1.6×), because at that point they’d overlap and you should cook in batches instead.
Check during the last 2–3 minutes
The calculator is a starting point. Air fryers differ in fan strength and basket size. Open it 2–3 minutes before the estimated time, check the color and doneness, and add a minute or two if needed. For meat and fish, always cut into the thickest part to make sure it’s cooked through.
