Indulge in gooey and crispy mozzarella sticks made in the Ninja Foodi Air Fryer. Cut mozzarella cheese into sticks, dip them in beaten egg, coat with breadcrumbs, and place them in the air fryer basket. Cook at a high temperature for about 8-10 minutes until the cheese is melted and the coating is golden brown. Serve with marinara sauce for a delicious appetizer or snack.
