01 - Bring a large pot of salted water to a boil. Add the tortellini and cook for 2 minutes less than the package directions so they remain 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, dried Italian herbs, salt, and black pepper until evenly mixed.
03 - Dip each tortellini into the egg mixture, allowing excess to drip off, then coat evenly in the breadcrumb mixture. Press gently to help the coating adhere firmly to each piece.
04 - To fry: Heat 1 inch of vegetable oil in a deep skillet to 350°F. Fry the tortellini in batches for 2-3 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 the breaded tortellini in a single layer on a parchment-lined baking sheet. Spray generously with olive oil spray. Bake for 12-15 minutes, turning halfway through, until golden and crisp.
05 - Transfer the crispy tortellini to a serving platter and serve warm alongside heated marinara sauce for dipping.
