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 with cold water to stop cooking. Pat dry thoroughly with paper towels.
02 - In a shallow bowl, whisk together eggs and milk. In a separate shallow bowl, combine breadcrumbs, Parmesan cheese, garlic powder, Italian herbs, salt, and pepper. Mix until evenly distributed.
03 - Dip each tortellini first into the egg mixture, then coat evenly with the breadcrumb mixture. Press gently to ensure the coating adheres well on all sides.
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 for 12 to 15 minutes, turning halfway through, until golden and crisp.
05 - Serve warm with heated marinara sauce for dipping.
