Crockpot Lasagna Soup is the kind of cozy dinner that brings all the comfort of classic lasagna into one hearty, spoonable bowl. It has the rich tomato flavor, tender pasta, seasoned beef, creamy ricotta, and Parmesan finish you love, but without all the layering and baking.
What makes this recipe so easy to love? The slow cooker does most of the work. After a quick stovetop browning of the beef, onion, and garlic, everything simmers into a saucy, savory broth that tastes like it has been cooking all day.
This crockpot lasagna soup feeds a crowd, making it perfect for family dinners, meal prep, busy weekends, or chilly nights when everyone wants something warm and filling. With 10 servings, there is plenty to go around—and maybe even leftovers for lunch the next day.
Why You’ll Love This Crockpot Lasagna Soup
Why go through the work of assembling a full lasagna when you can enjoy the same flavors in a cozy soup?
This recipe combines lean ground beef, marinara sauce, diced tomatoes, tomato paste, broken lasagna noodles, and fresh spinach in a rich beef broth. The result is saucy, hearty, and deeply satisfying.
I love how the broken lasagna noodles soak up all that tomato-rich flavor while still keeping their tender bite. Then comes the best part: a creamy dollop of whole milk ricotta on top. It melts slightly into the hot soup, giving every spoonful that classic lasagna-style creaminess.
This is also a family-friendly recipe. The original notes mention that home cooks love how kids and teens devour the soup and ask for more, which makes it a reliable dinner when you need something comforting but practical.

This soup uses simple ingredients, but they come together in a way that tastes rich, layered, and comforting.

1 1/2 pounds 93/7 lean ground beef
1 1/2 cups finely chopped yellow onion
6 cloves garlic, finely chopped
1 1/2 teaspoons table salt, divided
3/4 teaspoon freshly ground black pepper, divided
6 cups beef broth
1 24-ounce jar marinara sauce, such as Rao’s
1 15-ounce can diced tomatoes, drained
1 6-ounce can basil, garlic, and oregano tomato paste
1/4 teaspoon crushed red pepper, plus more for garnish

Ingredient Notes
The ground beef gives this soup its hearty, classic lasagna flavor. A lean 93/7 beef works well because it adds richness without making the broth greasy.
The onion and garlic create the savory base. Since the garlic is finely chopped, it blends beautifully into the tomato broth instead of overpowering it.
The combination of marinara sauce, diced tomatoes, and tomato paste is what gives the soup its thick, saucy texture. The tomato paste with basil, garlic, and oregano adds extra Italian-style flavor without needing a long list of dried herbs.
Lasagna noodles are broken into bite-sized pieces so they cook directly in the slow cooker. This keeps the recipe easy while still giving you that unmistakable lasagna feel.
Fresh baby spinach adds color, freshness, and a little balance to the rich broth. Stir it in at the end so it stays bright and tender.
And don’t skip the ricotta. That creamy topping is what makes this soup feel like lasagna in a bowl.
How to Make Crockpot Lasagna Soup
Step 1: Brown the Beef
Start by gathering all your ingredients so everything is ready to go.
In a large nonstick skillet over medium-high heat, combine the ground beef, chopped yellow onion, garlic, 1/2 teaspoon salt, and 1/2 teaspoon black pepper.
Cook, stirring occasionally, until the beef is no longer pink and the onions have softened. This should take about 8 minutes. Once cooked, transfer the beef mixture to a 6-quart slow cooker.
Step 2: Build the Tomato Broth
Add the beef broth, marinara sauce, drained diced tomatoes, tomato paste, crushed red pepper, remaining 1 teaspoon salt, and remaining 1/4 teaspoon black pepper to the slow cooker.
Stir everything together until the tomato paste is fully mixed into the broth. At this point, the soup already smells rich and comforting, but the slow cooker will help deepen the flavor even more.
Step 3: Slow Cook the Soup
Cover the slow cooker and cook on LOW for 3 1/2 to 4 hours, or on HIGH for 2 hours.
As the soup cooks, the beef, tomatoes, garlic, onion, and broth blend together into a slightly thickened tomato base. It should be saucy, but still loose enough to feel like soup.
Step 4: Add the Lasagna Noodles
Stir the broken lasagna noodles into the crockpot, making sure the pieces are submerged in the liquid.
Cover and cook on HIGH for about 30 minutes, or until the pasta is al dente. Keep an eye on the noodles near the end of cooking so they do not become too soft.
Step 5: Stir in the Spinach
During the last 5 minutes of cooking, stir in the chopped fresh baby spinach.
The spinach wilts quickly, so it only needs a few minutes. This final addition gives the soup a fresh pop of green and helps balance the rich tomato broth.
Step 6: Serve with Ricotta and Parmesan
Ladle the hot lasagna soup into bowls. Top each serving with a generous dollop of whole milk ricotta cheese and freshly grated Parmesan.
For a little extra heat, garnish with more crushed red pepper.
Tips for the Best Crockpot Lasagna Soup
Don’t add the noodles too early. If lasagna noodles cook for the full slow cooker time, they can become mushy. Add them near the end so they stay tender but not overcooked.
Use a good marinara sauce. Since marinara is a major part of the broth, choose one with a flavor you enjoy.
Break the noodles evenly. Pieces around 1 3/4 inches are easy to eat and cook more evenly in the soup.
Add the spinach at the end. This keeps it fresh, bright, and tender instead of overcooked.
Serve the ricotta on top instead of stirring it into the whole pot. This gives each bowl a creamy lasagna-style finish and keeps leftovers easier to store.
Crockpot Lasagna Soup Substitutions and Variations
This soup is easy to adjust based on what you have in your kitchen.
You can swap the ground beef for Italian sausage if you want a bolder, more seasoned flavor. Ground turkey also works if you want a lighter version.
If you like extra vegetables, try adding chopped zucchini, mushrooms, or bell peppers with the beef mixture.
For a cheesier bowl, add shredded mozzarella on top with the ricotta and Parmesan.
Want more spice? Increase the crushed red pepper or use a spicy marinara sauce.
If you do not have lasagna noodles, another short pasta can work in a pinch, but lasagna sheets give the soup its signature feel.
What to Serve with Crockpot Lasagna Soup
This soup is hearty enough to stand on its own, but it is even better with something simple on the side.
Serve it with garlic bread, toasted Italian bread, a crisp green salad, or roasted vegetables. A little extra Parmesan at the table is never a bad idea either.
For a cozy family dinner, pair it with warm bread and let everyone add their own ricotta, Parmesan, and crushed red pepper.
How to Store Crockpot Lasagna Soup
Store leftover soup in an airtight container in the refrigerator.
Because pasta continues to absorb liquid as it sits, the soup may thicken after chilling. Add a splash of beef broth or water when reheating to loosen it back up.
Warm leftovers gently on the stovetop or in the microwave until heated through. For the best texture, store the ricotta separately and add it fresh when serving.
