Ingredients

Main Ingredients

  • 20 ounces frozen Italian style meatballs
  • 1 medium yellow onion, diced
  • 3 teaspoons garlic, minced
  • 6 cups low-sodium chicken broth
  • 28 ounces canned diced tomatoes
  • 6 ounce can tomato paste
  • 1 teaspoon black pepper
  • 1 teaspoon Italian seasoning
  • 1 teaspoon paprika
  • ½ teaspoon dried thyme

Thickening and Dairy

  • 2 tablespoons cornstarch
  • 1 ½ cups heavy cream

Pasta and Cheese

  • 16 ounces dry ditalini pasta
  • 1 cup Parmesan cheese, finely shredded

Greens

  • 4 cups fresh baby spinach

Instructions

  1. Combine Ingredients: In the slow cooker, add the frozen meatballs, diced yellow onion, minced garlic, low-sodium chicken broth, diced tomatoes, tomato paste, black pepper, Italian seasoning, paprika, and dried thyme. Stir gently to combine all ingredients evenly.
  2. Slow Cook: Cover the slow cooker and cook on high for 3-4 hours or on low for 6-8 hours until the meatballs are cooked through and flavors meld together.
  3. Prepare Thickener: In a small bowl, whisk together the cornstarch and heavy cream until smooth and free of lumps. Pour this mixture into the slow cooker to thicken the soup.
  4. Add Pasta and Greens: Stir in the ditalini pasta, finely shredded Parmesan cheese, and fresh baby spinach. Continue cooking for an additional 15-30 minutes on high until the pasta is tender and the spinach has wilted.
  5. Serve: Stir the soup once more before serving to ensure all ingredients are well distributed. Ladle hot into bowls and enjoy your comforting slow cooker meatball soup!

Notes

  • Time-Saving Tip: Use a food processor or small food chopper to quickly dice the onions evenly.
  • Adjust Soup Thickness: If the soup becomes too thick after adding pasta, simply add more chicken broth to reach desired consistency.
  • Storage and Reheating: Keep leftovers refrigerated for up to 3 days. Freezing is not recommended as pasta tends to become mushy. Reheat gently on the stovetop or in short microwave intervals.
