01 - Bring a large pot of salted water to a boil. Add tortellini and cook for 2 minutes less than package directions until al dente. Drain and immediately rinse under cold water to halt cooking. Pat thoroughly dry with paper towels.
02 - In a shallow bowl, whisk together the eggs and milk. In a separate shallow bowl, combine the breadcrumbs, Parmesan cheese, garlic powder, Italian herbs, salt, and pepper, mixing evenly.
03 - Dip each tortellini into the egg mixture, allowing excess to drip off, then press gently into the breadcrumb mixture, turning to coat all sides. Ensure an even, adherent crust on each piece.
04 - To fry: Heat 1 inch of vegetable oil in a deep skillet to 350°F. Fry tortellini in batches for 2 to 3 minutes, turning occasionally, until golden brown and crispy. Remove with a slotted spoon and drain on paper towels. To bake: Preheat oven to 425°F. Arrange breaded tortellini in a single layer on a parchment-lined baking sheet. Spray generously with olive oil spray. Bake 12 to 15 minutes, turning halfway through, until golden and crisp.
05 - Transfer warm tortellini to a serving platter alongside warmed marinara sauce for dipping.
