Green beans in the air fryer
Green beans takes 4 to 8 minutes at 415°F (215°C) in an air fryer, shaken or turned at 3 minutes.
What to know about air frying green beans
Cosori lists whole green beans at 415°F for 4 to 8 minutes with a shake. This is the fastest vegetable in the index and one of the fastest things full stop — beans are thin-walled and hollow, so heat reaches the middle almost immediately. Preheating matters more here than for anything else in this category, because a machine still warming up spends most of a four-minute cook not yet at temperature.
The mistake people make
Treating the range as advisory and walking away. Four minutes to eight minutes is the difference between blistered and shrivelled, and unlike a potato there is no thermal mass to buffer the mistake. Set an actual timer for four minutes and look.
How to tell when it's done
Blistered and browned in patches with the beans still holding a straight shape and some snap. Beans that have gone limp and khaki have lost both texture and colour and will not come back.

What temperature should I air fry green beans at?
415°F, or about 215°C. That sits above the 350–400°F band the USDA describes as typical, because browning rather than cooking through is the limiting factor here.

Yes. Use a light spray of oil. Keep it to a single layer — crowding the basket blocks the air circulation the machine depends on, which the USDA specifically warns about. Preheat the machine first.

Preheating: when it matters and when it is a waste of time
Preheating an air fryer matters enormously for a four-minute cook and barely at all for a forty-minute one. Here is the rule, and how long it actually takes.
How much oil to use in an air fryer
Some foods need no oil at all, some need a teaspoon, and using none at all on vegetables is why they burn. Which is which, and which oil to use.
