How To Make Slow Cooker Meatball Vegetable Soup

Step 1: Place the frozen meatballs, potatoes, carrots, celery, onion, garlic, green beans, and corn into the slow cooker.

Step 2: Pour in the tomato sauce and broth. Add the salt, pepper, Italian seasoning, garlic powder, and onion powder. Stir gently.

Step 3: Cover and cook on Low for 6 to 8 hours or High for 3 to 4 hours, until the vegetables are tender and the flavors have come together.

Step 4: Taste and adjust the seasonings as needed. Ladle into bowls and top with fresh parsley.

Tips and Tricks

• Use frozen meatballs to keep this recipe simple and quick.
• If you want a thicker soup, mash a few of the potatoes right in the pot.
• Add a splash of broth if the soup gets too thick during cooking.
• For an even deeper flavor, give everything a stir about halfway through if you happen to be home.

Substitutions

• Meatballs can be beef, turkey, chicken, or plant based. For something different, you could even use the tender meatballs from our Crockpot Swedish Meatballs.
• Green beans can be swapped for peas or extra corn.
• Beef broth can be replaced with chicken broth for a lighter flavor.

Variations

• Creamy version: Stir in half a cup of heavy cream during the last hour of cooking, similar to the technique in our McAlister’s Potato Soup.
• Italian version: Add a handful of small pasta during the final thirty minutes.
• Spicy version: Add red pepper flakes or a splash of hot sauce.

Storage Tips

• Refrigerate: Store leftovers in a sealed container for up to 4 days.
• Freeze: Freeze for up to 3 months, then thaw overnight in the refrigerator before reheating.
• Reheat: Warm gently on the stove or in the microwave, adding a splash of broth if it has thickened.

Frequently Asked Questions

Can I use fresh meatballs instead of frozen? Yes. Fully cooked fresh or homemade meatballs work just as well. If you are using raw meatballs, brown them first or be sure they reach a safe internal temperature, since the slow cooker keeps food in the danger zone longer than the stove.

Do I need to thaw the frozen meatballs first? No. The meatballs go into the slow cooker straight from frozen. They warm through gently and soak up the broth as everything cooks.

Can I use fresh vegetables instead of canned green beans and corn? Absolutely. Add about a cup of each. Fresh or frozen green beans and corn can go in at the start, since the long cook time will soften them nicely.

Can I add pasta or rice? Yes. Stir in a handful of small pasta during the final thirty minutes, or add cooked rice just before serving so it does not turn mushy.

Why is my soup too thick or too thin? For a thinner soup, stir in a splash more broth. For a thicker, heartier texture, mash a few of the potatoes right in the pot.

Can I make this on the stovetop instead? Yes. Simmer everything in a large pot over medium-low heat for 30 to 40 minutes, until the potatoes and carrots are tender.

Is this soup freezer friendly? It is. Cool it completely, then freeze for up to 3 months. Potatoes can soften a little after freezing, but the flavor stays delicious.
