01 - Set up three shallow bowls: place flour in the first bowl, whisk eggs with milk in the second bowl, and combine panko breadcrumbs, Parmesan cheese, oregano, garlic powder, salt, and pepper in the third bowl.
02 - Pat mozzarella cubes dry with paper towels to remove excess moisture, ensuring better coating adherence.
03 - Dredge each mozzarella cube in flour, shaking off excess. Dip into egg mixture, then press firmly into breadcrumb mixture to coat thoroughly. For extra-crispy texture, repeat the egg and breadcrumb dipping process.
04 - Arrange coated cheese balls on a baking tray and freeze for 15 minutes to firm up the coating, which helps prevent cheese from melting too quickly during frying.
05 - Pour vegetable oil into a deep saucepan or fryer until 2-3 inches deep. Heat to 350°F, maintaining temperature throughout frying.
06 - Fry cheese balls in small batches for 1-2 minutes until golden brown and crispy. Remove with a slotted spoon and drain on paper towels to absorb excess oil.
07 - Serve immediately while hot and gooey, accompanied by marinara sauce or your preferred dipping sauce.
