Frequently asked questions
Why is the air fryer temperature lower than the oven temperature?
Air fryers are small, high-powered convection ovens — the fast-moving hot air cooks food faster than a regular oven at the same temperature. Lowering the temperature by about 25°F (20°C) and checking a few minutes early gives a similar result to the original oven recipe.
Do I also need to change the cooking time for an air fryer?
Usually, yes — in addition to lowering the temperature, cut the original cooking time by about 20%, then check for doneness. Air fryers vary by model, so treat this as a starting point rather than an exact rule.
What's a gas mark?
Gas mark is the temperature scale used on older and UK gas ovens. It doesn't convert to Celsius or Fahrenheit with a simple formula, so the table uses the standard reference values used on UK oven dials.
