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
2 tablespoons cornstarch
1 ½ cups heavy cream
16 ounces dry ditalini pasta
1 cup Parmesan cheese, finely shredded
4 cups fresh baby spinach

Instructions

Step 1: Add the frozen meatballs, diced onion, minced garlic, chicken broth, diced tomatoes, tomato paste, black pepper, Italian seasoning, paprika, and dried thyme to your slow cooker. Stir everything together well.
Step 2: Cover and cook on high for 3 to 4 hours or on low for 6 to 8 hours, allowing the flavors to meld and the meatballs to cook through.
Step 3: In a small bowl, whisk together the cornstarch and heavy cream until smooth and lump-free. Pour this mixture into the soup, stirring gently to combine.
Step 4: Add the dry ditalini pasta, Parmesan cheese, and fresh baby spinach to the slow cooker. Continue cooking for 15 to 30 minutes until the pasta reaches your preferred tenderness.
Step 5: Stir the soup well before serving to evenly distribute the ingredients, then enjoy your comforting bowl of meatball soup!

Tips & Variations

For a lighter version, substitute half-and-half for heavy cream or use low-fat milk with a tablespoon of flour to thicken.
If you prefer a vegetarian option, replace meatballs with plant-based alternatives or extra vegetables like mushrooms and zucchini.
Use gluten-free pasta to accommodate dietary restrictions without sacrificing texture.
Add crushed red pepper flakes for a spicy kick.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of broth or water if the soup seems too thick. For longer storage, freeze the soup without the pasta for up to 3 months; add fresh pasta when reheating.

FAQs

Can I use fresh meatballs instead of frozen?

Yes, fresh meatballs can be used. You may want to brown them first in a skillet for added flavor before adding them to the slow cooker. Adjust cooking time if necessary to ensure they are cooked through.

What can I substitute for ditalini pasta?

You can substitute other small pasta shapes like elbow macaroni, small shells, or orzo. Just keep in mind that cooking times might vary slightly depending on the pasta type.
