preheat the air fryer at 400° for 5 minutes

once preheated add the frozen green beans

cook on 390° for 5 minutes or until beans are thawed and starting to cook

put beans in a bowl toss with the oil, salt, pepper, and garlic

toss to coat

put back in the air fryer for another 4 minutes on 390°, then shake and air fry again for 4 more minutes or until fully cooked

beans should be fully cooked and crispy in spots when they're done

if you like them cooked longer by all means put them in again for another couple of minutes
