Freeze mozzarella cubes for 30 minutes (prevents melting too quickly).
Set up breading station: 1) flour + garlic powder, 2) beaten eggs, 3) panko + Parmesan + Italian seasoning.
Dredge each cheese cube: flour → egg → breadcrumb mixture (press firmly to adhere). For extra crunch, repeat egg and breadcrumb steps.
Heat oil to 375°F (190°C). Fry bites in batches for 1-2 minutes until golden brown. Drain on paper towels.
Serve immediately with warm marinara sauce. For air fryer version: Cook at 400°F for 8-10 minutes.
Notes
Freeze unbreaded cheese cubes for up to 1 month - perfect for last-minute appetizers! For best results, maintain oil temperature and don't overcrowd the pan.
