01 - Preheat air fryer to 375°F for 3 minutes to ensure optimal cooking temperature.
02 - If using frozen tortellini, cook according to package directions until just tender; drain thoroughly and pat dry to remove excess moisture.
03 - In a shallow bowl, whisk together the eggs and milk until fully combined.
04 - In a separate bowl, combine panko breadcrumbs, grated Parmesan cheese, Italian seasoning, garlic powder, salt, and black pepper; mix well.
05 - Dip each tortellini into the egg mixture, allowing excess to drip off, then press firmly into the breadcrumb mixture to coat evenly on all sides.
06 - Place coated tortellini in a single layer in the air fryer basket, ensuring pieces do not overlap; work in batches if necessary.
07 - Lightly spray tortellini with olive oil spray; air fry for 7-9 minutes, shaking the basket halfway through cooking, until golden brown and crispy.
08 - Transfer to a serving platter and serve hot with warmed marinara sauce for dipping; garnish with fresh basil leaves if desired.
