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 the cooking process. Pat thoroughly dry with paper towels.
02 - In a shallow bowl, whisk together the eggs and milk until well combined. In a separate shallow bowl, mix the breadcrumbs, Parmesan cheese, garlic powder, dried Italian herbs, salt, and black pepper until evenly distributed.
03 - Working in batches, dip each tortellini into the egg mixture, allowing excess to drip off, then transfer to the breadcrumb bowl. Coat evenly on all sides, pressing gently so the breading adheres firmly to the surface.
04 - To fry: Heat 1 inch of vegetable oil in a deep skillet to 350°F. Fry the coated 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 the oven to 425°F. Arrange the breaded tortellini in a single layer on a parchment-lined baking sheet. Spray generously with olive oil spray and bake for 12 to 15 minutes, flipping halfway through, until golden and crisp.
05 - Transfer the crispy tortellini to a serving platter while still warm. Serve alongside warmed marinara sauce for dipping.
