Cooking frozen mozzarella sticks in an air fryer is seriously the BEST way to make pre-cooked and breaded mozzarella cheese sticks. They turn out perfect and super crisp, yet cook up faster than heating them in the oven.
Arrange the frozen mozzarella sticks in a single layer in an air fryer tray or in a basket.
Cook the mozzarella cheese sticks for a total of 6 minutes, flipping half-way if desired. Cook them until the cheese is just about to burst.
Serve them with pizza sauce, marinara sauce, or as is.
Notes
Cook the cheese sticks from frozen, do not let them defrost before cooking.
If you didn't preheat your air fryer, you might need to add 2-3 minutes to the cooking time.
Cook the mozzarella sticks until they're just about to burst but pull them out before they actually do. It's easier to keep an eye on them in an air fryer oven with a glass window.
Flipping the mozzarella cheese sticks is optional and might depend on your model of air fryer. Experiment to see which way gets the cheese sticks just how you prefer them.
You can make them "healthier" by buying brands that don't add sugar or artificial ingredients, which also gives you more of a homemade cheese stick taste.
