01 - Set air fryer to 375°F and preheat for 3 minutes to ensure optimal crisping conditions.
02 - Cook frozen tortellini according to package directions until al dente. Drain thoroughly and pat completely dry with paper towels to remove excess moisture.
03 - Whisk together eggs and milk in a shallow bowl until fully combined and smooth.
04 - Combine panko breadcrumbs, Parmesan cheese, Italian seasoning, garlic powder, salt, and black pepper in a separate shallow bowl. Mix until evenly distributed.
05 - Working in batches, dip each tortellini into the egg wash, allowing excess to drip off. Press firmly into the breadcrumb mixture, ensuring complete coverage on all sides.
06 - Place coated tortellini in a single layer in the air fryer basket, leaving space between pieces for proper air circulation. Cook in multiple batches if needed.
07 - Lightly mist the tortellini with olive oil cooking spray to promote even browning and crispiness.
08 - Cook for 7 to 9 minutes, shaking the basket vigorously halfway through cooking time. Continue until golden brown and crispy throughout.
09 - Transfer crispy tortellini to a serving platter. Serve hot alongside warm marinara sauce for dipping, garnished with fresh basil leaves if desired.
