Before it goes in the basket
Trim the stem ends, dry them, and toss with just enough oil to make them shine — beans are smooth-skinned and oil runs off them, so a bowl toss beats a spray every time. Leave the tapered tail on; it crisps.
Step by step
- 1. Preheat the air fryer to 380°F (195°C) for 2–3 minutes.
- 2. Single layer. Arrange without crowding — air needs to reach every side.
- 3. Cook 8–10 minutes. Shake the basket or flip at the halfway mark.
- 4. Check doneness. Blistered spots on the skin with a tender-crisp bite — squeaky means underdone.
The tip that matters
A teaspoon of soy sauce in the oil toss gives steakhouse-style blistered beans.
Why this temperature
380°F blisters the skin without collapsing the bean. Green beans have a waxy surface that needs real heat to break through; a gentle bake just softens them into the texture of tinned beans.
What usually goes wrong
- Squeaky and raw-tasting. Underdone. Beans need the full 8–10 minutes even though they look ready earlier.
- Shrivelled and leathery. Too long, or the beans were old. Fresh beans snap when bent; old ones bend.
- Oil pooled in the basket. Too much oil on a smooth surface. A teaspoon for a whole batch is plenty.
Times vary — here's why
Air fryers differ in wattage and basket size, so treat 8–10 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.
