Before it goes in the basket
Strip the leaves off the stems, tear them to a similar size, and dry them properly — water and hot air make steam, and steamed kale is limp. A teaspoon of oil for a whole bunch, worked in with your hands until every leaf is barely shiny. Then weigh them down with a rack or a light metal trivet.
Step by step
- 1. Preheat the air fryer to 300°F (150°C) for 2–3 minutes.
- 2. Single layer. Arrange without crowding — air needs to reach every side.
- 3. Cook 4–6 minutes. No flipping needed.
- 4. Check doneness. Edges are crisp and translucent while the centres of the leaves are still dark green, not brown.
The tip that matters
Weigh them down with a rack or a light metal trivet. This is the one thing in the basket that wants a low temperature and constant watching.
Why this temperature
300°F is the lowest setting anything in this basket gets, and it is not a compromise. A dry leaf is a few tenths of a millimetre thick and has no water left to buy it time: at normal air-fryer heat it goes from green to bitter ash inside a minute. Low and watched is the only way this works.
What usually goes wrong
- Burnt and bitter. Too hot, or unattended. There is no middle stage to catch — check at three minutes and every thirty seconds after.
- Stuck to the top of the machine. Not weighed down. The fan lifts dry leaves onto the element guard, where they burn immediately.
- Limp, not crisp. Wet leaves or too much oil. Both keep the surface from drying, which is the whole of what a chip is.
Times vary — here's why
Air fryers differ in wattage and basket size, so treat 4–6 minutes as a range, not a promise: check early the first time, then note what your machine needed. Quantity matters too — a full basket can add 2–3 minutes, and anything stacked will steam instead of crisp. Converting your own oven recipe instead? Use our air fryer conversion calculator.
