Ingredients You Need

Main ingredients

1 pound ground Italian sausage
- Use mild or hot depending on your spice level.
- Swap with lean ground beef or ground turkey if you prefer.
1 small yellow onion, diced
4 cloves garlic, minced
1 red bell pepper, diced (optional but adds sweetness and color)
1 can (28 ounces) crushed tomatoes
1 can (15 ounces) tomato sauce
1 can (14.5 ounces) diced tomatoes, undrained
- Use fire roasted diced tomatoes for a deeper flavor.
4 cups low sodium chicken broth or vegetable broth
2 tablespoons tomato paste
1 tablespoon Italian seasoning
1 teaspoon dried basil
1 teaspoon dried oregano
1 teaspoon sugar (balances the acidity)
1 to 1½ teaspoons kosher salt, to taste
½ teaspoon black pepper
½ to 1 teaspoon red pepper flakes, optional for heat
8 to 10 regular lasagna noodles, broken into bite size pieces
- Use gluten free lasagna noodles if needed.
- You can also use mafalda or bowtie pasta as a shortcut.

Cheese topping

1½ cups shredded mozzarella cheese
½ cup shredded or grated parmesan cheese
1 cup ricotta cheese
- Use cottage cheese if you want a lighter option.
1 tablespoon chopped fresh parsley or basil, plus more for garnish

Pantry shortcuts and notes

Jarred marinara sauce: Replace the crushed tomatoes and tomato sauce with 3 to 4 cups of your favorite marinara if you want a shortcut.
Pre minced garlic: Use 1½ tablespoons from a jar if you do not want to mince cloves.
Pre shredded cheese: Works fine here, though fresh shredded mozzarella melts smoother.

Equipment

5 to 7 quart slow cooker or Crockpot
Large skillet for browning meat
Wooden spoon or spatula
Ladle for serving
Small bowl for mixing the cheese topping

Tips & Mistakes

Brown the meat fully and drain excess grease so the soup tastes rich, not oily.
Season the meat while it browns to build flavor early instead of dumping all spices into the slow cooker at the end.
Break lasagna noodles into similar sized pieces so they cook evenly and do not turn mushy.
Add the pasta near the end of cooking so it stays tender but not soggy.
Taste the broth before adding noodles and adjust salt, since cheese will add extra saltiness.
Keep the lid on the slow cooker as much as possible so the soup maintains heat and cooks on schedule.
Stir gently after adding noodles so they do not clump together in one big pasta blob.
Add the cheese mixture to each bowl right before serving so it stays creamy and does not disappear into the soup.
Use low sodium broth so you control the salt level and avoid an overly salty soup.
Cool leftovers before refrigerating so they do not steam up the container and water down the soup.

How to Make Crockpot Lasagna Soup Recipe

Step 1: Brown the meat and aromatics

Heat a large skillet over medium high heat. Add the ground Italian sausage and break it into crumbles while it cooks. Sprinkle with a pinch of salt and pepper, then cook until the meat browns and no pink remains.

Add the diced onion and bell pepper to the skillet and cook 3 to 4 minutes until they soften. Stir in the minced garlic and cook 30 to 60 seconds until it smells fragrant. Drain excess grease, then transfer the meat mixture to the slow cooker.

Step 2: Build the soup base in the slow cooker

Pour the crushed tomatoes, tomato sauce, and diced tomatoes with their juices into the slow cooker. Add the tomato paste, Italian seasoning, dried basil, dried oregano, sugar, salt, black pepper, and red pepper flakes if you use them. Stir everything until the tomato paste dissolves and the seasonings mix evenly.

Pour in the chicken broth and stir again. Taste a spoonful of the broth and adjust salt or red pepper flakes to your liking. Cover the slow cooker with the lid.

Step 3: Cook the soup

Cook on low for 5 to 6 hours or on high for 3 to 4 hours. The flavors will deepen, and the broth will thicken slightly as it simmers. Stir once or twice during cooking if you walk by, but keep the lid closed most of the time.

Step 4: Add the lasagna noodles

About 30 to 40 minutes before serving, break the lasagna noodles into bite size pieces. Stir them into the hot soup, making sure the noodles sit under the liquid. Cover again and cook on high for 25 to 35 minutes until the noodles turn tender but still hold their shape.

Stir gently once during this time so the noodles do not stick together. Taste a noodle to check doneness. If the soup looks too thick, add a splash of broth or water to loosen it.

Step 5: Mix the cheese topping

While the noodles cook, stir the ricotta, shredded mozzarella, and parmesan together in a small bowl. Add a pinch of salt, pepper, and the chopped fresh parsley or basil. Mix until the cheese forms a thick, creamy mixture.

Keep this cheese mixture in the fridge until you serve. This mixture gives you that classic lasagna bite when you swirl it into the hot soup.

Step 6: Serve

Once the noodles reach tender perfection, turn the slow cooker to warm. Ladle the Crockpot Lasagna Soup into bowls. Add a generous scoop of the cheese mixture to the center of each bowl and let it melt into the soup.

Sprinkle extra mozzarella or parmesan on top if you feel cheesy. Finish with more fresh basil or parsley for color and freshness.

Variations I've Tried

Turkey lasagna soup: Use ground turkey instead of sausage, bump up the Italian seasoning, and add a splash of extra tomato paste for richness.
Veggie lasagna soup: Skip the meat and add extra bell peppers, zucchini, mushrooms, and spinach, then use vegetable broth.
Cheesy white lasagna soup: Use chicken broth, skip the crushed tomatoes, add more broth and a little cream, and load up on mozzarella and parmesan with spinach and chicken.
Spicy lasagna soup: Use hot Italian sausage, fire roasted tomatoes, and extra red pepper flakes, then finish with a dollop of ricotta to cool each bite.
Gluten free lasagna soup: Use gluten free lasagna noodles or another gluten free pasta and check that your broth and sausage stay gluten free.

How to Serve Crockpot Lasagna Soup Recipe

Serve Crockpot Lasagna Soup Recipe in deep bowls so the broth, noodles, and cheese have room to mingle. Top each bowl with a scoop of the ricotta mixture, extra mozzarella, and a sprinkle of fresh basil or parsley. Add a side of garlic bread, simple green salad, or roasted vegetables for a full meal.

Kids often love this with a side of fruit like apple slices or grapes, which balances the richness. A cold glass of water, sparkling water, or iced tea pairs nicely with the warm, hearty soup.

How to store

Fridge: Cool the soup completely, then store it in airtight containers in the refrigerator for up to 4 days.
Freezer: Freeze the soup without the noodles for best texture, up to 3 months, and add fresh cooked noodles when you reheat; if you freeze with noodles, expect a softer texture.
Cheese mixture: Store the ricotta cheese mixture separately in a small container in the fridge for up to 3 days.
Reheating on stove: Reheat gently in a pot over medium low heat, stirring often, and add a splash of broth or water if it thickened in the fridge.
Reheating in microwave: Heat individual bowls in the microwave in 45 to 60 second bursts, stirring between each, until hot; add the cheese mixture after heating so it stays creamy.
