Notes

  • Browning the meatballs before slow cooking adds extra flavor but is optional.
  • Substitute ground turkey or chicken for a lighter version.
  • Frozen meatballs can be used in a pinch—just make the gravy from scratch.
  • Add a splash of cream or sour cream at the end for a creamier gravy.
  • Store leftovers in the fridge for up to 4 days or freeze for up to 2 months.
