Prepare your workspace by setting up three bowls: one with flour, one with beaten eggs, and one with seasoned breadcrumbs and Italian seasoning.

Coat each mozzarella stick in flour, then dip in egg wash, and finally roll in the breadcrumb mixture.

Chill the breaded mozzarella sticks on a baking sheet in the freezer for 30 minutes.

Preheat the air fryer to 390°F (200°C) and spray the basket with cooking spray.

Arrange the chilled mozzarella sticks in the air fryer basket, mist with cooking spray, and cook for 6-8 minutes until golden brown.

Remove from the air fryer, let cool slightly, and serve with warm marinara sauce.
