Fall Crockpot Meatball Soup is a hearty one-pot meal with tender beef meatballs, carrots, celery, tomatoes, and thyme. The meatballs cook directly in the slow cooker, while the vegetables soften in the tomato-based broth and pick up plenty of savory flavor.
A handful of kale added near the end gives the soup a fresh finish without changing its hearty character. Serve it with crusty bread for an easy fall dinner that doesn’t require much hands-on cooking.
What Makes This Soup a Family Favorite
- Tender Meatballs: The slow cooker keeps the meatballs moist as they cook in the broth.
- Full Meal in One Pot: Meat, vegetables, and broth come together in a single dish.
- Simple Preparation: The meatballs only need to be mixed, shaped, and added to the slow cooker.
- Tomato-Based Broth: Undrained diced tomatoes add flavor and body to the soup.
- Optional Kale: Add it at the end for extra color and texture.
- Easy Weeknight Dinner: Most of the cooking happens while the soup simmers.
Ingredient Notes
- Ground Beef: Choose ground beef with enough fat to keep the meatballs tender.
- Breadcrumbs: They help hold the meatballs together and keep their texture soft.
- Egg: Acts as a binder so the meatballs don’t fall apart during cooking.
- Diced Tomatoes: Keep the tomatoes undrained so their juices become part of the broth.
- Chicken Broth: Chicken broth works well with the beef and vegetables, but beef broth can also be used.
- Thyme: Dried thyme gives the broth a simple herbal flavor.
- Kale: This is optional and should be added near the end so it doesn’t become overly soft.
Helpful Tip: Don’t pack the meatball mixture too tightly when shaping it. A light touch helps keep the finished meatballs tender.

Fall Crockpot Meatball Soup
Equipment
- Slow Cooker
- Ladle
Ingredients
- 1.5 pounds ground beef for meatballs
- 1 cup breadcrumb for binding the meatballs
- 1 large egg to help hold meatballs together
- 2 cloves garlic minced
- 1 teaspoon dried thyme
- 1 can (14.5 oz) diced tomatoes undrained
- 4 cups chicken broth
- 2 carrots carrots sliced
- 2 stalks celery chopped
- 1 small onion diced
- 1 cup kale chopped, optional
- Salt and pepper to taste
Instructions
- Combine ground beef, breadcrumb, egg, minced garlic, dried thyme, and a pinch of salt and pepper in a large mixing bowl. Mix gently until everything is evenly incorporated, being careful not to overmix. Form mixture into small meatballs about 1 inch in diameter and set aside.

- Place the prepared meatballs in the slow cooker evenly, making sure they aren’t crowded to ensure even cooking.

- Add diced tomatoes, chicken broth, sliced carrots, chopped celery, and diced onion to the slow cooker. Stir gently to combine, ensuring the vegetables are submerged in the broth.

- Cover the slow cooker with the lid and set to low heat. Let the soup simmer for about 4 hours until the meatballs are cooked through and the vegetables are tender, filling the house with a rich, savory aroma.

- Once cooking time is up, open the lid and add chopped kale if desired. Stir gently and let it wilt for about 5 minutes, allowing the greens to soften and absorb flavors.

- Use a ladle to serve the hearty soup into bowls, ensuring each portion contains tender meatballs and a mix of vegetables. Adjust salt and pepper seasoning to taste before serving.

A Few Meatball Tips
- Don’t Overmix: Mix just until the ingredients come together.
- Keep the Meatballs Similar in Size: This helps them cook at the same rate.
- Don’t Flatten Them: Shape them gently into balls rather than pressing them tightly.
- Leave the Lid Closed: Frequent opening slows the slow cooker’s cooking process.
- Add Kale Late: It only needs a few minutes to soften.
- Check Before Serving: The meatballs should be fully cooked in the center.
What Goes Well With It
- Crusty Bread: Perfect for soaking up the tomato broth.
- Garlic Toast: Adds crunch and extra garlic flavor.
- Green Salad: A fresh salad balances the hearty soup.
- Roasted Vegetables: Serve alongside for a larger dinner.
- Simple Pasta: A small serving of pasta can make the meal even more filling.
- Parmesan Toast: Add grated Parmesan to toasted bread for an easy side.

FAQs
- Can I use frozen meatballs instead of homemade?
Yes. Frozen fully cooked meatballs can be used to shorten the preparation time. Add them directly to the slow cooker and cook until heated through. - Can I make smaller meatballs for this soup?
Yes. Smaller meatballs work well and can make the soup easier to eat with a spoon. Keep them similar in size so they cook evenly. - Can I brown the meatballs before slow cooking?
Yes. Browning them in a skillet first adds extra color and flavor, although it isn’t required for the recipe. - Can I add pasta to the soup?
Yes. Small pasta shapes such as ditalini or small shells work well. Cook the pasta separately if you want to prevent it from absorbing too much broth. - Can I use ground turkey instead of beef?
Yes. Ground turkey can replace the beef, though the meatballs may have a slightly lighter flavor and texture. - How can I make the broth richer?
Use beef broth instead of chicken broth, or add a small splash of Worcestershire sauce to deepen the savory flavor.

hi there,
The Freshman Cook started as a place to keep track of recipes I wanted to make again. Somewhere along the way, it grew into a collection of meals that friends requested, desserts that disappeared too quickly, and weeknight dinners that made life a little easier.
