Cut the mozzarella sticks in half crosswise to create 16 smaller sticks.

Prepare a dredging station with three shallow bowls: one containing flour, one containing beaten eggs, and one containing panko mixed with Italian seasoning, garlic powder, and salt.

Coat each cheese stick in flour, shaking off any excess.

Dip the floured stick into the egg wash, then press into the panko mixture until fully coated.

Repeat the egg and panko dip a second time for each stick to create a double coating, which prevents the cheese from leaking.

Place the breaded sticks on a parchment-lined tray and freeze for at least 2 hours until completely solid.

Preheat the air fryer to 400°F (200°C).

Lightly spray the air fryer basket with cooking oil.

Arrange the frozen sticks in a single layer in the basket, ensuring they do not touch.

Spray the tops of the sticks with cooking oil and air fry for 5 to 7 minutes, turning halfway through, until golden brown.
