Begin by cutting your part-skim cheese sticks in half, creating 24 delightful pieces perfect for snacking. Place the halved sticks on a plate and set them aside.

Prepare your breading station by arranging three shallow dishes - one with flour, one with whisked egg, and one with breadcrumbs mixed with seasonings.

Dredge the cheese stick in flour, dip it in the egg, then roll it in the seasoned breadcrumbs until fully coated.

Place the coated mozzarella sticks on a baking sheet lined with a silicone mat and freeze them for at least one hour.

Preheat your air fryer to 385°F (195°C). Arrange the frozen sticks in the basket, lightly spray with non-stick spray, and cook for about 5 minutes until golden brown.

Alternatively, preheat your oven to 425°F (220°C). Bake the frozen mozzarella sticks for 9-10 minutes until golden and crispy.
