Rinse green beans and cut off the stems. Either pat them dry or let them air dry.

Set up a breading station. Arrange 3 bowls in front of you. Add flour to the first bowl. Beat the eggs in the second bowl. Mix together breadcrumbs, Parmesan cheese, garlic powder, salt and pepper in the third bowl.

Working with a few green beans at a time, drop them in the flour and toss them around to coat evenly in the flour. Shake off any excess flour, then add them the eggs and mix until they are nice and coated. Add the green beans to the panko mixture and press the breadcrumbs into the beans.

Set the coated green beans on a baking sheet or plate while you continue with the rest of them.

Arrange green beans in a single layer in your air fryer basket. You want to make sure they aren't touching or on top of each other. Cook at 390º for 5 minutes, gently flip them and cook for an additional 5 minutes until they are nice and crispy.

Remove from the air fryer and continue with another batch of necessary.
