Prepare the Green Beans. Wash and trim the ends off the green beans. Pat them completely dry to ensure maximum crispiness.
Season the Green Beans. In a bowl, toss the green beans with olive oil, garlic powder, paprika, salt, and black pepper. Dip the beans in whisked egg first, then coat with breadcrumbs and Parmesan cheese.
Air Fry to Perfection. Preheat the air fryer to 375°F. Arrange the green beans in a single layer in the air fryer basket (avoid overcrowding). Air fry for 8-10 minutes, shaking the basket halfway through for even crisping.
Serve and Enjoy. Once crispy and golden brown, transfer to a serving plate. Serve immediately with your favorite dipping sauce or as a side dish.
