Indulge in gooey and crispy mozzarella sticks made in your Gourmia air fryer. Cut mozzarella cheese into sticks, dip them in beaten egg, coat with breadcrumbs, and freeze for 30 minutes. Preheat the air fryer to 400°F, spray the mozzarella sticks with cooking oil, and air fry for 6-8 minutes until golden and melted. Serve with marinara sauce for a delicious appetizer or snack.
