01 - Preheat the air fryer to 400°F for 3 minutes.
02 - If using frozen tortellini, cook according to package instructions; drain and let cool slightly.
03 - Arrange three bowls: one with flour, one with beaten eggs and milk whisked together, and one with breadcrumbs, Parmesan, garlic powder, herbs, salt, and pepper combined.
04 - Dredge each tortellini in flour, shake off excess, dip in egg mixture, then press into breadcrumb mixture to coat evenly.
05 - Place breaded tortellini in a single layer in the air fryer basket. Spray lightly with cooking oil.
06 - Cook for 8–10 minutes, shaking the basket halfway through cooking, until golden brown and crispy.
07 - Transfer to a serving platter and serve hot with warm marinara sauce. Garnish with chopped fresh herbs if desired.
