01 - Preheat air fryer to 375°F for 3 minutes before starting the cooking process.
02 - If using frozen tortellini, cook according to package directions until just tender; drain thoroughly and pat dry with paper towels to remove excess moisture.
03 - In a shallow bowl, whisk together the eggs and milk until well combined and smooth.
04 - In a separate shallow bowl, combine panko breadcrumbs, grated Parmesan cheese, Italian seasoning, garlic powder, salt, and black pepper. Mix thoroughly to distribute seasoning evenly.
05 - Dip each tortellini into the egg mixture, allowing excess to drip off, then press into the breadcrumb mixture to coat all sides completely. Ensure breading adheres firmly.
06 - Place coated tortellini in a single layer in the air fryer basket, leaving space between pieces for proper air circulation. Work in batches if necessary to avoid overcrowding.
07 - Lightly spray tortellini with olive oil spray. Air fry for 7-9 minutes, shaking the basket halfway through cooking time, until exterior is golden brown and crispy.
08 - Transfer crispy tortellini to serving plates immediately. Accompany with warm marinara sauce for dipping and garnish with fresh basil leaves if desired.
