Wash and dry green beans.
In a large bowl, toss together green beans, oil, salt, and pepper until beans are coated with oil.
Add the green beans to air fryer basket, arranging them in a single layer. You may have to cook them in batches (see note).
Air fry at 380ºF until tender but still crisp, about 8 minutes, tossing 1 or 2 times during cooking. If desired, sprinkle Parmesan cheese on beans a couple of minutes before they are done.
We also tested air frying the beans all at once, not in a single layer, adding 4 minutes to the cooking time. They turn out perfectly acceptable but not quite as flavorful or browned. It’s really a matter of preference.
