Set up three shallow bowls: one with flour, one with beaten eggs mixed with a splash of water, and one with panko breadcrumbs seasoned with garlic powder and Italian seasoning.

Unwrap and cut each string cheese stick in half if desired.

Dredge each cheese stick in flour, dip in the egg mixture, then roll in panko until fully coated.

Freeze for at least 30 minutes to maintain shape during cooking.

Preheat your air fryer to 390°F (200°C).

Arrange frozen mozzarella sticks in a single layer in the air fryer basket; spray lightly with cooking oil.

Air fry for 6-8 minutes until golden brown and crispy.
