how long do you cook frozen uncooked meatballs?
Bake the meatballs for the time recommended on the packaging. If you're cooking frozen, fully cooked homemade meatballs, allow around 10 to 12 minutes for bite-sized meatballs, 15 to 20 minutes for medium-sized (two-bite) ones and 20 to 25 minutes for larger meatballs (three or more bites).
