Put flour in one bowl, beaten eggs in a second, and panko with Parmesan, Italian seasoning, garlic powder, and salt in a third.

Roll each cheese stick in flour, dip in egg, then press into the panko mix to coat all sides.

Place breaded sticks on a parchment-lined plate without touching and freeze for at least 30 minutes until firm.

Preheat air fryer to 390°F (200°C). Spray frozen sticks generously with oil and arrange in a single layer in the basket. Air fry for 5 to 6 minutes until golden.

Let sticks rest in the basket 1 minute, then plate with warm marinara for dipping.
