01 - Line a baking sheet with parchment paper for easy cleanup and cheese removal.
02 - Slice mozzarella cheese into stick shapes if not pre-cut, ensuring uniform sizing.
03 - Arrange sticks in a single layer on the baking sheet and freeze for at least 1 hour until very firm to prevent melting during baking.
04 - Preheat oven to 425°F. Place a wire rack on a second baking sheet and lightly coat with olive oil spray.
05 - Set up three shallow bowls: Bowl 1 with flour, Bowl 2 with whisked eggs and milk, Bowl 3 with panko, Italian breadcrumbs, garlic powder, oregano, basil, salt, and pepper mixed together.
06 - Working quickly with a few sticks at a time, coat each frozen mozzarella stick in flour shaking off excess, dip in egg mixture, then roll in breadcrumb mixture pressing to adhere. For extra crunch, repeat egg and breadcrumb coating once more.
07 - Arrange breaded sticks on the prepared wire rack, spacing them apart to allow even air circulation.
08 - Generously spray the tops with olive oil spray to promote golden browning.
09 - Bake for 8-10 minutes, turning halfway and spraying the other side, until golden and crisp. Watch closely to prevent cheese from oozing out.
10 - Let cool 2 minutes before serving to allow cheese to set slightly. Serve warm with marinara sauce.
