Place the frozen meatballs in the bottom of a 6-quart slow cooker.
Pour the marinara sauce over the top, ensuring that the meatballs are evenly coated.
Sprinkle the shredded mozzarella and grated Parmesan over the meatballs and sauce.
Cover the slow cooker and let it work its magic on high for 2-3 hours, or until the meatballs are fully heated through and the cheese has melted into a glorious, gooey blanket.
