Slow Cooker 5-Ingredient Lasagna Soup

This 5-ingredient slow cooker lasagna soup became one of those recipes the grandkids could smell from the doorway and they still race to the table when it appears.

The best part is that you get that familiar old-fashioned comfort food flavor without layering noodles, spreading cheese, or assembling a casserole.
It is an especially wonderful fall slow cooker recipe because the crockpot does most of the work while the kitchen fills with the irresistible aroma of tomato sauce, sausage, and bubbling cheese.

Ingredients
1 pound ground Italian sausage
The sausage provides the savory, seasoned foundation of the soup. Italian sausage brings garlic, herbs, and spices that help make the broth flavorful without needing a long list of seasonings. Brown it before adding it to the slow cooker for the best texture and flavor.
1 jar (24 ounces) marinara sauce
Marinara sauce supplies the rich tomato base and gives the soup its unmistakable lasagna character. Choose a good-quality sauce you already enjoy eating on its own.
4 cups chicken broth
The chicken broth transforms the thick marinara into a spoonable soup while adding another layer of savory flavor. It also gives the broken noodles plenty of liquid to absorb as they cook.
8 lasagna noodles, broken into pieces
The noodles turn ordinary tomato soup into lasagna soup. Break them into manageable pieces so they are easy to scoop and eat. They also release some starch as they cook, naturally giving the broth a heartier texture.
2 cups shredded mozzarella
Mozzarella cheese provides the classic stretchy, melty finish associated with lasagna. One cup is stirred into the soup for richness, while the remaining cup goes over the top just before serving.
How to Make Slow Cooker Lasagna Soup
Step 1: Brown the sausage
Cook the Italian sausage in a skillet over medium heat until browned and cooked through. Break it into small pieces as it cooks.
If there is a large amount of excess grease, carefully drain it before continuing.
Step 2: Build the soup
Add the browned sausage to your slow cooker.
Pour in the marinara sauce and chicken broth. Stir everything together well so the sausage is evenly distributed throughout the tomato broth.
Step 3: Slow cook
Cover the slow cooker and cook on LOW for 4 to 5 hours or HIGH for 2 to 3 hours.
The goal is to give the sausage, tomato sauce, and broth time to come together into a rich, fragrant base.
Step 4: Add the lasagna noodles
About 30 minutes before serving, break the lasagna noodles into bite-size pieces and stir them into the soup.
Cover and continue cooking until the noodles are tender.
Keep an eye on the noodles near the end of cooking because slow cookers can vary, and you do not want them to become overly soft.
Step 5: Add the cheese
Stir 1 cup of shredded mozzarella into the hot soup. Give it a moment to melt into the broth, creating a rich and cheesy texture.
Ladle the soup into bowls and sprinkle the remaining 1 cup mozzarella over each serving.
Let it sit for a minute or two so the cheese begins to melt into those steaming bowls.
Pro Tips for Perfect Lasagna Soup
Brown the sausage first. This gives the meat better texture and develops deeper savory flavor than simply adding raw sausage to the slow cooker.
Do not add the noodles too early. Lasagna noodles can become overly soft if they spend the entire cooking time in the slow cooker. Adding them during the final portion of cooking helps them stay pleasantly tender.
Break the noodles evenly. Aim for pieces that are roughly bite-size so every spoonful is easy to eat.
Watch the broth. Pasta continues absorbing liquid as it sits. If the soup becomes thicker than you prefer, stir in a little additional chicken broth when reheating.
Use freshly shredded mozzarella when possible. It melts beautifully and gives the finished soup that classic stretchy-cheese effect.
For an extra lasagna-style finish, add a small spoonful of ricotta to each bowl. It is optional, but the creamy richness pairs beautifully with the tomato and sausage.
Make-Ahead Tip
For an easier slow cooker dinner, brown the Italian sausage the night before and refrigerate it.
The next morning, add the sausage, marinara sauce, and chicken broth to the slow cooker. Let the soup cook while you go about your day, then add the broken noodles and cheese toward the end.
It is exactly the kind of easy family dinner that makes busy fall days feel a little less hectic.
What to Serve With Lasagna Soup
Because this soup is hearty on its own, simple sides work best.
Serve it with warm garlic bread for dipping into the tomato-rich broth. A crisp green salad adds freshness, while buttered green beans make an easy vegetable side.
For a cozy family-style meal, set out a basket of crackers or crusty bread and let everyone add their own toppings.
If you are serving adults, a glass of red wine pairs naturally with the Italian-inspired flavors. For children, a cold drink and a bowl of crackers alongside the soup make a wonderfully simple supper.
Easy Variations
Want to make this slow cooker lasagna soup your own?
– Add a spoonful of ricotta cheese to each bowl for an even more traditional lasagna flavor.
– Use spicy Italian sausage if your family enjoys a little heat.
– Add a handful of baby spinach during the final few minutes for extra vegetables.
– Sprinkle Parmesan over the mozzarella for an additional cheesy finish.
– Use a combination of mozzarella and Italian-blend cheese for a richer topping.
How to Store Leftovers
Allow leftover soup to cool before transferring it to an airtight container. Refrigerate and enjoy within a few days.
Because the noodles continue absorbing broth as they sit, leftover lasagna soup will usually become thicker. Add a splash of chicken broth when reheating to bring it back to a more soup-like consistency.
Frequently Asked Questions
Can I use regular lasagna noodles?
Absolutely. Traditional lasagna noodles work perfectly. Simply break them into smaller pieces before adding them to the slow cooker.
Can I make this without Italian sausage?
Yes. Ground beef can be substituted, although the flavor will be slightly different. If using a less-seasoned meat, you may want to add Italian seasoning and garlic to taste.
Can I add ricotta?
Yes. A spoonful of ricotta on top of each serving makes the soup taste even more like classic baked lasagna.
Why did my soup get too thick?
The noodles continue absorbing liquid after cooking. Simply stir in additional warm broth until the soup reaches your preferred consistency.
