01 - Preheat air fryer to 375°F for 3 minutes.
02 - If using frozen tortellini, cook according to package directions until just tender; drain and pat dry thoroughly.
03 - In a shallow bowl, whisk together the eggs and milk until well combined.
04 - In another bowl, combine panko, Parmesan, Italian seasoning, garlic powder, salt, and pepper.
05 - Dip each tortellini in the egg mixture, then coat thoroughly with the breadcrumb mixture, pressing gently to adhere.
06 - Arrange coated tortellini in a single layer in the air fryer basket; work in batches if necessary to avoid overcrowding.
07 - Spray tortellini lightly with olive oil spray and air fry for 7-9 minutes, shaking the basket halfway through, until golden and crisp.
08 - Serve immediately with warm marinara sauce and fresh basil, if desired.
