Preheat your air fryer to 375°F (190°C) for about 5 minutes.
In a shallow bowl or plate, place the flour. In another bowl, beat the eggs. In a third plate, mix the breadcrumbs with garlic powder, oregano, salt, and black pepper.
Take each frozen cheese ravioli and coat it in the flour, ensuring it's fully covered.
Dip the floured ravioli in the beaten eggs, allowing any excess to drip off.
Coat the ravioli with the seasoned breadcrumb mixture, pressing gently to ensure the crumbs stick well.
Place the coated ravioli on a small baking sheet in a single layer and spray them lightly with cooking spray for extra crispiness.
Carefully arrange the ravioli in a single layer in the air fryer basket, making sure they do not overlap.
Cook the ravioli in the air fryer for about 8-10 minutes, flipping them halfway through the cooking time.
Once cooked, remove the ravioli bites from the air fryer and serve them warm with marinara sauce on the side for dipping.
