01 - Bring a large pot of salted water to a boil. Add tortellini and cook for 2 minutes less than 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. Mix until evenly distributed.
03 - Dip each tortellini first into the egg mixture, allowing excess to drip off, then coat evenly in the breadcrumb mixture. Press gently on all sides to ensure the coating adheres firmly. Place on a clean plate or tray.
04 - For frying: 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. For baking: 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 the crispy tortellini to a serving platter and serve warm alongside warmed marinara sauce for dipping.
