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 until fully combined. In a separate shallow bowl, mix the breadcrumbs, Parmesan cheese, garlic powder, dried Italian herbs, salt, and black pepper until evenly blended.
03 - Dip each tortellini into the egg wash, allowing excess to drip off, then transfer to the breadcrumb mixture. Coat evenly on all sides, pressing gently so the crumbs adhere firmly to the surface.
04 - To fry: heat 1 inch of vegetable oil in a deep skillet to 350°F. Fry the breaded 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. Bake for 12 to 15 minutes, flipping halfway through, until golden and crisp.
05 - Serve the crispy tortellini warm alongside heated marinara sauce for dipping.
