01 - Bring a large pot of salted water to a boil and cook the tortellini according to package directions until al dente. Drain thoroughly and spread on a plate to cool slightly.
02 - In a shallow bowl, whisk together the eggs and milk until well combined. In a separate shallow bowl, mix the panko breadcrumbs, grated Parmesan, Italian seasoning, garlic powder, salt, and black pepper.
03 - Working in small batches, dip each cooked tortellini into the egg wash, allowing excess to drip off, then press firmly into the breadcrumb mixture to coat evenly on all sides.
04 - Pour vegetable oil into a deep skillet or heavy-bottomed saucepan to a depth of 1 inch. Heat over medium-high heat until the oil reaches 350°F.
05 - Carefully lower the coated tortellini into the hot oil in small batches. Fry for 2 to 3 minutes, turning occasionally, until deeply golden and crispy on all sides.
06 - Remove the fried tortellini with a slotted spoon and transfer to a plate lined with paper towels to drain. Serve warm alongside the heated marinara dipping sauce.
