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 black pepper in the third bowl.
02 - Pat mozzarella cubes thoroughly 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 completely. For extra-crispy texture, repeat the egg and breadcrumb coating steps.
04 - Arrange coated cheese balls on a baking tray and freeze for 15 minutes. This chilling step helps set the coating and prevents cheese from melting too quickly during frying.
05 - Pour vegetable oil into a deep saucepan or fryer to reach 2-3 inches depth. Heat to 350°F, maintaining consistent temperature throughout frying.
06 - Fry cheese balls in small batches for 1-2 minutes until golden brown and crispy. Remove using a slotted spoon and drain immediately on paper towels to absorb excess oil.
07 - Transfer hot cheese balls to a serving platter and pair with warm marinara sauce or preferred dipping accompaniment. Serve promptly while cheese remains gooey and center.
