Lasagna Soup – Cozy, Hearty, and Weeknight-Friendly

Lasagna soup gives you everything you love about classic lasagna without the layers and long bake time. It’s rich, tomatoey, and loaded with tender noodles, savory meat, and melty cheese. The broth is creamy and comforting, but still bright with herbs and a hint of tang.

If you love a big bowl of something that feels like a hug, this is it. It comes together on the stove in about 40 minutes and tastes even better the next day.

What Makes This Special

This soup blends the best parts of lasagna—bold sauce, layered cheeses, and pasta—into one cozy pot. You still get the signature trio of ricotta, mozzarella, and Parmesan, but they melt into each spoonful rather than sitting in layers.

The broth is hearty enough for a main course and simple enough for a weeknight. It’s easy to customize with different meats, extra veggies, or gluten-free pasta. And the finishing dollop of cheese on top makes it feel restaurant-worthy without much effort.

Ingredients

• 1 tablespoon olive oil
• 1 pound Italian sausage (mild or hot), casings removed (or use ground beef/turkey)
• 1 small yellow onion, diced
• 3 cloves garlic, minced
• 1 tablespoon tomato paste
• 1 teaspoon Italian seasoning
• 1 teaspoon dried oregano
• 1/2 teaspoon crushed red pepper flakes (optional, for heat)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 (28-ounce) can crushed tomatoes
• 4 cups low-sodium chicken broth (or vegetable broth)
• 1 cup water (as needed to adjust thickness)
• 8–10 lasagna noodles, broken into bite-size pieces (about 6 ounces, or use mafalda/mini lasagna noodles)
• 1/3 cup heavy cream (or half-and-half)
• 1/2 cup freshly grated Parmesan cheese, plus more for serving
• 1 cup shredded mozzarella
• 1 cup ricotta cheese
• Fresh basil or parsley, chopped, for garnish

How to Make It

1. Brown the sausage. Heat the olive oil in a large pot or Dutch oven over medium-high heat.
   

   Add the sausage and cook, breaking it into crumbles, until browned and cooked through, about 5–7 minutes. Spoon off excess fat if needed.

   
   
2. Soften the aromatics. Add the diced onion and cook until translucent, about 3–4 minutes. Stir in the garlic and cook 30 seconds, just until fragrant.
3. Build the flavor base. Stir in the tomato paste, Italian seasoning, oregano, red pepper flakes (if using), salt, and black pepper.
   

   Cook 1 minute to toast the spices and caramelize the paste slightly.

   
   
4. Add tomatoes and broth. Pour in the crushed tomatoes and chicken broth. Bring to a gentle boil, then reduce to a simmer. Let it bubble for 10 minutes to blend the flavors.
5. Cook the noodles in the soup. Add the broken lasagna noodles.
   

   Simmer, stirring often to prevent sticking, until al dente, about 10–12 minutes. Add up to 1 cup water if the soup gets too thick.

   
   
6. Make the cheese mixture. While the noodles cook, stir together ricotta, half the Parmesan, and a pinch of salt and pepper in a small bowl. This will be your dollop for serving.
7. Finish the soup. Stir in the heavy cream and the remaining Parmesan.
   

   Taste and adjust salt and pepper. Turn off the heat and fold in the mozzarella so it melts into the soup but still has some stretch.

   
   
8. Serve and garnish. Ladle into bowls and top each with a spoonful of the ricotta mixture. Sprinkle with extra Parmesan and fresh basil or parsley.
   

   Serve hot.

   
   

How to Store

• Refrigerator: Store soup (without the ricotta topping) in an airtight container for up to 4 days. Keep the ricotta mixture separate.
• Freezer: For best results, freeze the broth and meat mixture without noodles for up to 3 months. Add freshly cooked pasta when reheating to avoid mushiness.
• Reheating: Warm gently on the stove over medium-low heat, adding a splash of broth or water to loosen.
  

  Stir occasionally to prevent sticking.

  
  
• Make-ahead tip: Cook the noodles separately and add them to bowls just before serving. This keeps them from soaking up too much liquid in storage.

Benefits of This Recipe

• Weeknight-friendly: Big lasagna flavor without hours in the oven.
• Flexible: Works with sausage, ground beef, turkey, or a vegetarian base.
• Comforting but balanced: Rich cheeses and a creamy finish, with bright tomato and herbs to keep it lively.
• Great for leftovers: Tastes even better the next day as flavors meld.
• Family-pleasing: Familiar flavors that kids and adults love.

Common Mistakes to Avoid

• Overcooking the noodles: They keep softening as the soup sits. Cook just to al dente and pull the pot off the heat.
• Not stirring the pasta: Broken lasagna pieces can stick together.
  

  Stir every couple of minutes as they cook.

  
  
• Skipping the tomato paste: It adds depth and that slow-simmered flavor. Don’t leave it out.
• Adding all the cheese at once: Stir some into the soup and reserve the ricotta for topping so you get creamy bites and a nice presentation.
• Forgetting to salt in layers: Season the meat, the sauce, and the finish. It prevents a flat-tasting soup.

Variations You Can Try

• Vegetarian: Swap sausage for a mix of mushrooms and chopped zucchini.
  

  Use vegetable broth and add a can of white beans for protein.

  
  
• Lean and light: Use ground turkey, skip the cream, and finish with extra broth plus a squeeze of lemon for brightness.
• Spicy arrabbiata: Use hot Italian sausage, extra red pepper flakes, and a pinch of smoked paprika.
• Pesto finish: Stir a spoonful of basil pesto into each bowl instead of fresh herbs for a fresh, garlicky kick.
• Gluten-free: Use sturdy gluten-free pasta and cook it separately, adding it to bowls before serving.
• Spinach lasagna soup: Fold in a few handfuls of baby spinach or chopped kale during the last 2 minutes of cooking.
• Three-cheese boost: Add a bit of provolone with the mozzarella for extra melt and flavor.

FAQ

Can I cook the noodles separately?

Yes. Cook them in salted water until al dente, then add to each bowl before ladling in the soup. This keeps the texture firm and is ideal for meal prep.

What can I use instead of Italian sausage?

Ground beef, turkey, or chicken work well.

If you want the same flavor profile, add extra fennel seeds, garlic, and a pinch of red pepper flakes to mimic sausage seasoning.

How do I make it dairy-free?

Use olive oil instead of cream and skip the cheeses. For creaminess, stir in a splash of unsweetened cashew cream or a spoonful of dairy-free ricotta just before serving.

Will the soup thicken as it sits?

Yes. The pasta absorbs liquid over time.

Thin with extra broth or water when reheating until you reach your preferred consistency.

Can I use a different pasta shape?

Absolutely. Mafalda, bowties, or rotini all work. Choose a sturdy shape that holds up to simmering and reheating.

Is this spicy?

It’s mildly spiced if you use red pepper flakes or hot sausage.

For a no-heat version, use mild sausage and skip the flakes.

How can I add more vegetables?

Sauté diced carrots, celery, and bell pepper with the onion. You can also add chopped spinach or zucchini in the last few minutes of cooking.

Can I make this in a slow cooker?

Yes, with tweaks. Brown the meat and aromatics first, then cook on low with tomatoes and broth for 4–6 hours.

Add pasta during the last 20–30 minutes and finish with cream and cheeses at the end.

What’s the best way to get a cheesy top?

Top each bowl with a dollop of ricotta, extra mozzarella, and Parmesan. If you want a bubbly finish, transfer portions to oven-safe bowls, top with cheese, and broil briefly.

How do I keep it from tasting too acidic?

If your tomatoes are sharp, stir in 1 teaspoon sugar or a knob of butter at the end. A splash of cream also softens the acidity.
