Ingredients You Need

Ground meat

1 pound ground Italian sausage (mild or hot)
- Use bulk sausage or remove casings from links.
- Swap with lean ground beef or a 50/50 mix if you prefer less spice.
½ pound lean ground beef (90% lean works well)
- You can use all beef or all sausage if that fits your taste or budget.

Aromatics and flavor base

1 medium yellow onion, finely diced
4 cloves garlic, minced (use 1½ teaspoons garlic powder if you need a shortcut)
1 tablespoon tomato paste (tube tomato paste keeps well in the fridge)
1 tablespoon olive oil (only if your meat is very lean)

Tomatoes and broth

1 can (28 ounces) crushed tomatoes (I like Muir Glen or Cento for rich flavor)
1 can (15 ounces) tomato sauce
1 can (14.5 ounces) diced tomatoes, undrained
4 cups low-sodium chicken broth or vegetable broth
- Use low-sodium so you control the salt level.

Seasonings

2 teaspoons Italian seasoning
1 teaspoon dried basil
1 teaspoon dried oregano
1 teaspoon kosher salt (adjust to taste at the end)
½ teaspoon black pepper
½ teaspoon crushed red pepper flakes (optional, for a little heat)
1 teaspoon sugar (balances the acidity of the tomatoes)

Pasta

8–10 regular lasagna noodles, broken into bite-size pieces
- Use regular, not oven-ready, for best texture.
- You can swap with mafalda, bowties, or rotini if that’s what you have.

Cheesy topping

1½ cups shredded mozzarella cheese
½ cup shredded Parmesan cheese
1 cup ricotta cheese
1 teaspoon dried parsley or 1 tablespoon fresh chopped parsley
Pinch of salt and pepper

Optional add-ins

1 cup sliced mushrooms
1 small zucchini, diced
1 cup fresh spinach, roughly chopped (stir in at the end)

Equipment

6–7 quart slow cooker (crockpot style)
Large skillet for browning meat
Cutting board and knife
Wooden spoon or spatula
Ladle for serving

Quick Tips & substitutions

Brown the meat and onions before adding to the crockpot so the soup tastes richer and the fat renders properly.
Use all ground beef or all Italian sausage if that matches what you have on hand.
Swap regular lasagna noodles with gluten-free lasagna noodles and cook them slightly less so they stay firm.
Stir the pasta in during the last 30–40 minutes so it stays al dente and not mushy.
Mix the cheese topping right before serving so it stays creamy and doesn’t dry out.
Use cottage cheese instead of ricotta if you want more protein and a lighter feel.
Taste and adjust salt at the end, since broth brands and sausage salt levels vary a lot.
Add a handful of spinach or kale during the last 5–10 minutes for extra veggies without much effort.

How to Make Crockpot Lasagna Soup Recipe

Step 1: Brown the meat and onions

Heat a large skillet over medium-high heat and add the ground Italian sausage and ground beef. Break the meat into small crumbles and cook until it browns and no pink remains, about 6–8 minutes. Add the diced onion and cook 3–4 minutes until the onion softens and turns translucent, then stir in the minced garlic and cook 30 seconds so it smells fragrant.

If the pan has a lot of grease, drain most of it, but leave a tablespoon for flavor. Stir in the tomato paste and cook 1 minute so it caramelizes slightly and deepens the flavor.

Step 2: Load the crockpot

Transfer the meat mixture to the slow cooker. Add the crushed tomatoes, tomato sauce, diced tomatoes with their juices, and the chicken or vegetable broth. Stir in Italian seasoning, dried basil, dried oregano, salt, pepper, crushed red pepper flakes, and sugar.

Mix everything well so the seasonings distribute evenly. Cover the crockpot with the lid.

Step 3: Slow cook the soup base

Cook on LOW for 6–7 hours or on HIGH for 3–4 hours. The flavors deepen as it simmers, and the broth thickens slightly from the tomato base and meat. Stir once or twice if you happen to walk by, but you do not need to babysit it.

Taste the broth about 30 minutes before you plan to add the pasta. Adjust salt and pepper if needed so the soup tastes balanced and savory.

Step 4: Add the lasagna noodles

About 30–40 minutes before serving, break the lasagna noodles into bite-size pieces. Stir the broken noodles into the hot soup, making sure they submerge in the liquid. Cover again and cook on HIGH for 25–35 minutes, until the noodles turn tender but still hold their shape.

Stir once halfway through so the noodles do not clump together. If the soup looks too thick, add ½–1 cup extra broth and stir.

Step 5: Mix the cheese topping

While the noodles cook, stir together the ricotta, shredded mozzarella, shredded Parmesan, parsley, and a pinch of salt and pepper in a small bowl. Mix until the cheese mixture looks creamy and spreadable. This mixture will mimic the cheesy layers in classic lasagna.

Keep the cheese mixture in the fridge if your kitchen runs hot. Pull it out right before serving so it softens slightly.

Step 6: Finish and serve

When the noodles reach your desired tenderness, stir in any quick-cooking veggies like spinach and let them wilt for 2–3 minutes. Ladle the hot lasagna soup into bowls. Spoon a generous dollop of the ricotta cheese mixture on top of each bowl and let it melt into the soup.

Sprinkle extra mozzarella or Parmesan on top if you want a super cheesy finish. Serve hot with garlic bread or a simple green salad on the side.

Recipe Variations

Gluten-free: Use gluten-free lasagna noodles or gluten-free short pasta and check that your broth and sausage carry gluten-free labels.
Vegan: Use plant-based ground “meat,” vegetable broth, and dairy-free mozzarella, Parmesan, and ricotta alternatives.
Low carb: Skip the noodles and add sliced zucchini “noodles” or spaghetti squash strands near the end of cooking.
Extra veggies: Add mushrooms, zucchini, bell peppers, or carrots with the broth to boost texture and nutrition.
Spicy version: Use hot Italian sausage and extra crushed red pepper flakes for more heat.
Lighter version: Use ground turkey or chicken sausage and part-skim cheeses.

Ways to Serve Crockpot Lasagna Soup Recipe

With garlic bread or garlic toast for dipping into the cheesy broth.
Alongside a crisp green salad with Italian dressing.
With a side of roasted vegetables like broccoli, green beans, or carrots.
Topped with extra fresh basil, parsley, or a spoonful of pesto.
With warm breadsticks or simple buttered rolls for soaking up every last drop.

Storage Success

Let the Crockpot Lasagna Soup Recipe cool until it reaches room temperature, then store it in airtight containers in the fridge for up to 4 days. The noodles continue to absorb liquid, so add a splash of broth or water when you reheat it on the stove or in the microwave. If you plan to freeze portions, store the soup base without noodles and cheese, then add fresh noodles and cheese when you reheat. Freeze the base up to 3 months, thaw overnight in the fridge, and simmer gently before serving.
