This one passed the test on the very first spoonful. He was back at the pot for seconds before I had even sat down, and I’m still a little offended I didn’t get a head start.
Lasagna soup gives you everything you love about the baked version: the saucy sausage, the ruffly noodles, the stretchy cheese. It just skips the layering, the oven, and the hour of waiting.
Everything happens in one pot, and you’re eating in about 40 minutes.
The three cheeses are where this recipe really earns its spot on your table. Each one has its own job, and I’ll show you exactly what they do.
Side Note: I’ve made this soup at least a dozen times now, and the version below is the one I keep coming back to. It took a few soggy-noodle disasters to get here.
Why This Three-Cheese Lasagna Soup Works
Most lasagna soup recipes use one cheese and hope for the best. This one uses three, and that changes the whole bowl.
- Ricotta gives you creamy, cool dollops that melt slowly into the hot broth.
- Mozzarella brings the classic cheese pull that makes everyone reach for their phone.
- Parmesan adds a salty, nutty depth that makes the tomato broth taste like it simmered all day.
Here’s a fun one. The word ricotta means “recooked” in Italian, because it’s traditionally made from whey left over after making other cheeses. So you’re basically eating cheese made from cheese leftovers, and it’s delicious.
The other reason this works is timing. The noodles cook right in the soup, so they soak up flavor instead of just sitting in it.

| Olive oil | 1 tablespoon | Extra virgin is fine |
| Yellow onion | 1 medium | Diced small |
| Garlic cloves | 4 | Minced |
| Tomato paste | 2 tablespoons | The secret to a rich broth |
| Dried oregano | 1 teaspoon | Or Italian seasoning |
| Red pepper flakes | 1/2 teaspoon | Adjust to your heat level |
| Crushed tomatoes | 1 can (28 ounces) | Good quality makes a difference |
| Beef broth | 4 cups | Low sodium works best |
| Lasagna noodles | 8 ounces | Broken into bite-size pieces |

Tools You’ll Use
This is a one-pot kind of recipe, so the dish pile stays small. Here’s what I grab:
- Large Dutch oven or heavy-bottomed soup pot
- Wooden spoon
- Cutting board
- Chef’s knife
- Measuring cups and measuring spoons
- Small mixing bowl
- Ladle
- Box grater
Pro Tips for First-Time Lasagna Soup Makers
These come from my own messy trial and error, so you get to skip the mistakes.
- Break the noodles by hand. Snap them into pieces about the size of a large bite. Big pieces are messy to eat and small ones turn to mush.
- Cook the tomato paste. Stir it into the sausage for a full minute before adding liquid. It turns from bright red to a deeper brick color, and the flavor gets a lot richer.
- Shred your own mozzarella. Pre-shredded bags are coated with anti-caking starch, so the cheese doesn’t melt as smoothly.
- Watch the salt. Sausage, broth, and Parmesan are all salty. Taste at the very end, then decide.
- Serve it fast. The noodles keep drinking broth as the soup sits. Ladle it into bowls right after they turn tender.

How to Make Three-Cheese Lasagna Soup Step by Step
Total time is about 40 minutes, with 10 minutes of prep. This makes about 6 generous bowls.
Step 1: Brown the Sausage
Heat the olive oil in your Dutch oven over medium-high heat. Add the sausage and break it up with your wooden spoon.
Cook for 6 to 8 minutes, until no pink is left and you see some golden, crispy bits on the bottom. Those bits are pure flavor, so don’t scrape them away yet.
Step 2: Build the Flavor Base
Add the diced onion and stir. Cook for about 4 minutes, until soft and see-through.
Stir in the garlic, oregano, and red pepper flakes. Give it 30 seconds, just until your kitchen smells amazing.
Now add the tomato paste and stir it around for a full minute.
Step 3: Add the Liquid
Pour in the crushed tomatoes and beef broth. Scrape the bottom of the pot with your spoon to loosen all those browned bits.
Bring everything to a gentle boil, then lower the heat and let it simmer for 10 minutes. This gives the broth time to come together.
Step 4: Cook the Noodles Right in the Pot
Add the broken lasagna noodles and stir well. They love to stick together in the first minute or two.
Simmer for 10 to 12 minutes, stirring every few minutes, until the noodles are tender. Taste one to be sure.
Step 5: Mix the Ricotta Topping
While the noodles cook, stir the ricotta and half of the Parmesan together in your small bowl. Add a pinch of black pepper.
Set it aside. This is the creamy part, and it goes on at the very end.
Step 6: Melt in the Mozzarella
Turn the heat to low. Stir in 1 cup of the mozzarella a handful at a time, so it melts into the soup instead of clumping.
Taste and add salt and pepper if it needs them.
Step 7: Serve and Top
Ladle the soup into bowls. Add a big spoonful of the ricotta mixture in the center of each one.
Sprinkle with the remaining mozzarella, extra Parmesan, and the fresh basil. Serve right away, while the cheese is still stretchy.
Substitutions and Variations
This recipe is forgiving, which is why it’s on repeat at our house. Here are swaps that actually work:
| Instead of | Try | What Changes |
|---|---|---|
| Italian sausage | Ground beef or ground turkey | Milder taste, so add extra oregano |
| Beef broth | Chicken or vegetable broth | Lighter, slightly sweeter soup |
| Lasagna noodles | Mafalda corta or rotini | Easier to eat, but less ruffly |
| Ricotta | Cottage cheese, blended smooth | Tangier and a bit lighter |
| Fresh basil | Fresh parsley | Fresh and mild, less sweet |
Fun Variations
- Veggie-packed: Stir in 2 cups of fresh spinach at the end, or add diced mushrooms with the onion.
- Extra creamy: Add 1/2 cup of heavy cream right before the mozzarella.
- Vegetarian: Skip the sausage, use vegetable broth, and add sauteed mushrooms and a can of drained white beans.
- Spicy: Use hot Italian sausage and double the red pepper flakes.
Make-Ahead Tips
You can make the soup base up to 3 days ahead. Stop after the 10-minute simmer in Step 3 and cool it before it goes in the fridge.
When it’s time for dinner, reheat the base until simmering, then add the noodles and finish the recipe. Fresh noodles mean no mushy surprise.
You can also mix the ricotta topping a day early. Cover it and keep it cold.
Storing and Reheating Leftovers
The noodles drink up broth overnight, so leftover soup will look a lot thicker. Don’t panic. It’s easy to fix.
- Fridge: Store in an airtight container for up to 4 days.
- Reheating: Warm on the stove over medium-low heat and add a splash of broth or water to loosen it.
- Freezer: Freeze the soup without noodles for up to 3 months. Thaw in the fridge overnight, heat it up, and cook fresh noodles in it.
Skip the microwave if you can. It heats unevenly and turns the noodles rubbery.
Nutritional Snapshot
These are rough estimates for one serving (about 1/6 of the pot), so treat them as a guide. Exact numbers change based on your sausage and brand of cheese.

Swapping in ground turkey and skipping the extra Parmesan on top brings the calories down noticeably.
What to Serve With Lasagna Soup
This soup is filling on its own, but a few sides make it feel like a real Sunday dinner.
- Garlic bread for dunking, because it’s not optional in my house
- A crisp Caesar salad to balance the richness
- Roasted broccoli with lemon for something green and bright
- A simple arugula salad with olive oil and lemon juice
FAQs Related to Three-Cheese Lasagna Soup
1. Can I make lasagna soup in a slow cooker?
Yes. Brown the sausage and onion on the stove first, then move everything except the noodles and cheese to the slow cooker. Cook on low for 6 hours, then add the noodles for the last 30 minutes on high.
2. How do I keep the noodles from getting mushy?
Pull the soup off the heat as soon as the noodles are tender. Cooking them fresh each time also helps, especially with leftovers.
3. Can I use no-boil lasagna noodles?
You can, but they’re thinner and cook faster. Check them after 6 to 8 minutes.
4. Is lasagna soup gluten-free?
Not as written. You can use gluten-free lasagna noodles or pasta, but check the package for cooking time since it varies a lot.
5. Can I freeze lasagna soup?
Yes, for up to 3 months. Freeze it without noodles for the best texture.
6. What is the best cheese for lasagna soup?
Whole milk ricotta, low-moisture mozzarella, and real Parmesan give you the best mix of creamy, stretchy, and salty.
7. How many people does this recipe feed?
About 6 hungry adults. If you have big eaters at home, like I do, plan on 4 to 5 servings.
