Tips

  • Meatballs: You can make homemade meatballs and freeze them, or you can use your favorite frozen meatballs in this recipe.
  • Noodles: It’s important to use whole wheat noodles because they have a longer cooking time and hold up better in this soup. Gluten free elbow macaroni has a similar cooking time and should also hold up well in this recipe.
  • Serving: I like to serve the soup topped with a sprinkling of grated parmesan cheese. Fresh basil or fresh parsley also go well on top. This soup goes well with a loaf of crusty bread for dipping.

Storage

Store any leftover meatball soup in an airtight container in the refrigerator. The soup will keep for up to 4 days when properly stored.

However, the noodles will absorb some of the liquid as they sit, so you may need to add additional stock when reheating.
