Yes, you can. You will have to cook the beans for a few minutes longer. Otherwise, the recipe is the same. At the ten-minute mark, open the air fryer and toss the green beans with bacon again. If they aren’t fully coated in bacon grease, you can use some cooking spray. This will help the beans have a crispier exterior. We recommend cooking frozen green beans all the way through since they often don’t have the same tender-crisp texture as fresh ones once cooked.
