Cook for about fifteen to twenty minutes as an initial estimate, stirring periodically and following any longer package reheating requirement. Check several meatball centers reach 165°F, continuing as needed. Add a small splash of water if the sauce thickens before the centers are hot. Serve promptly or transfer fully heated meatballs to suitable hot-holding equipment.
