Freezer: Freeze the meatballs for up to 3 months. Make sure the container is sealed well to avoid freezer burn.

DANA’S TIPS AND TRICKS:

  • Brown the cooked meatballs in a large skillet with a little oil for extra flavor before slow cooking.
  • Use a wooden spoon to mix the ingredients gently in the crock pot.
  • Slice the onions to a medium thickness so they don’t melt into the sauce.
  • Stir the mixture occasionally during cooking.
  • Thicken the sauce with a flour-water mixture or water and cornstarch if needed.
  • Let the meatballs rest a few minutes after cooking to soak up more flavor.
