Equipment

  • 6-quart slow cooker

Method

Notes

  • Tip 1: Leftover meatballs can be stored in an airtight container in the fridge for three to four days.
  • Tip 2: These meatballs freeze beautifully! You can freeze them in sauce for up to three months. Simply thaw overnight in the fridge before reheating.
  • Tip 3: Pair your subs with crispy oven-baked fries or a fresh green salad to balance out the richness of the meatballs.
  • Tip 4: Assemble the meatballs the night before and store them in the fridge. In the morning, just pop them in the slow cooker to cook.
  • Tip 5: Feel free to add extras to your meatball mixture, such as chopped herbs or spices based on your preference.
