01 - Bring a large pot of salted water to a boil. Add the tortellini and cook for 2 minutes less than package directions so they remain al dente. Drain and immediately rinse under cold water to halt further cooking. 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.
03 - Dip each tortellini first into the egg wash, then roll in the breadcrumb mixture, pressing gently to ensure an even, adherent coating on all sides.
04 - To fry: Heat 1 inch of vegetable oil in a deep skillet to 350°F. Fry the tortellini in batches for 2 to 3 minutes, turning occasionally, until golden brown and crispy. Transfer to paper towels to drain. To bake: Preheat oven to 425°F. Arrange breaded tortellini in a single layer on a parchment-lined baking sheet and spray generously with olive oil spray. Bake 12 to 15 minutes, flipping halfway through, until golden and crisp.
05 - Arrange the crispy tortellini on a platter and serve warm alongside heated marinara sauce for dipping.
