That is what Italian sausage lasagna soup does to people. It tastes like a big, bubbly pan of lasagna, but it all happens in one pot and lands on the table in about 40 minutes.
No layering. No separate pot for noodles. No waiting an hour for something to come out of the oven.
I made my first batch on a random Tuesday when I wanted comfort food and had zero patience. It has been on repeat ever since, and I learned a few things along the way that will save you from my early mistakes. 🍝
Side Note: Stick around for the ricotta topping trick in the Pro Tips. It changes how the whole bowl eats.
Why This Italian Sausage Lasagna Soup Works
Italian sausage lasagna soup is a thick, tomato-based soup made with browned Italian sausage, broken lasagna noodles, and a creamy ricotta topping. It gives you the flavors of baked lasagna in a fraction of the time, using just one pot.
Here is why it works so well:
- The sausage seasons everything. Fennel, garlic, and spice from the meat flavor the whole broth, so you skip a long list of dried herbs.
- The noodles cook right in the soup. Their starch thickens the broth, which is why it feels hearty instead of watery.
- The ricotta goes on top. Every spoonful gets that cool, creamy bite you love in a classic lasagna.
- Cleanup is easy. One pot, one bowl for the cheese mix, done.
Here is the part that surprised me. A traditional lasagna often takes an hour or more from start to finish, and this soup gets you the same comfort in under 45 minutes.

Pro Tips for Making Lasagna Soup the First Time
I have made this soup more times than I can count. These are the things I wish someone had told me at the start.
- Break the noodles small. If you use regular lasagna noodles, snap them into bite-size pieces. Long pieces are messy to eat and slide right off the spoon.
- Stir the pot often once the noodles go in. They love to stick to the bottom. A quick stir every minute or two keeps them loose.
- Mix the ricotta topping ahead of time. Stir ricotta, half the Parmesan, a pinch of salt, and a little parsley in a small bowl. Seasoned ricotta tastes so much better than plain ricotta straight from the tub.
- Do not overcook the noodles. Pull the pot when they are just tender. They keep softening in the hot broth while you ladle and serve.
- Let the tomato paste darken. Cooking it for a full minute before adding liquid gives the soup that “simmered all day” flavor, and it costs you nothing.
How to Make Italian Sausage Lasagna Soup
Prep time: 10 minutes. Cook time: 30 minutes. Total time: 40 minutes. Serves: 6.
Step 1: Brown the Sausage
Heat the olive oil in your Dutch oven over medium-high heat. Add the sausage and break it into small crumbles with your wooden spoon.
Cook for 6 to 8 minutes, until it is browned and no pink remains. Spoon out all but about 1 tablespoon of the grease.
Step 2: Cook the Onion and Garlic
Drop the heat to medium and add the diced onion. Stir for 4 to 5 minutes, until it turns soft and see-through.
Add the garlic, tomato paste, Italian seasoning, and red pepper flakes. Stir for about 1 minute so the paste darkens a little and the kitchen starts to smell amazing.
Step 3: Build the Broth
Pour in the crushed tomatoes and chicken broth. Scrape the bottom of the pot with your spoon to loosen those tasty browned bits.
Bring everything to a boil, then lower the heat, cover, and simmer for 15 minutes.
Step 4: Cook the Noodles
Raise the heat so the soup bubbles gently. Stir in the broken noodles.
Cook uncovered for 10 to 12 minutes, or until they are tender but still have a little bite. Check the package for timing, since brands vary. Stir often.
Step 5: Add the Spinach
Turn off the heat and stir in the spinach. It wilts in about a minute from the hot soup alone.
Taste, then add salt and pepper as needed. Sausage and broth are already salty, so go slowly.
Step 6: Make the Ricotta Topping
While the noodles cook, stir the ricotta, 1/4 cup of Parmesan, a pinch of salt, and a little chopped parsley together in a small bowl.
Step 7: Serve It Up
Ladle the soup into bowls. Add a big spoonful of the ricotta mix, a handful of mozzarella, and a sprinkle of fresh basil.
Let it sit for a minute so the mozzarella softens. Then dig in.

Substitutions and Variations
This soup is forgiving. Swap in what you have and it still turns out great.
| Swap | What to Use Instead | What Changes |
|---|---|---|
| Italian sausage | Ground beef, ground turkey, or ground chicken | Add 1/2 teaspoon fennel seed to get that sausage flavor back |
| Chicken broth | Beef or vegetable broth | Beef broth gives a deeper taste |
| Mafalda noodles | Broken lasagna noodles, rotini, or small shells | Cook time may shift by a few minutes |
| Ricotta | Cottage cheese, blended smooth | Slightly tangier |
| Baby spinach | Chopped kale | Simmer kale 3 to 4 minutes before serving |
| Regular noodles | Gluten free lasagna noodles | Add near the end, they turn soft fast |
Fun Variations to Try
- Creamy lasagna soup: Stir in 1/2 cup heavy cream right after the spinach for a silky, rich finish.
- Spicy version: Use hot Italian sausage and double the red pepper flakes.
- Veggie boost: Add diced mushrooms or zucchini with the onion.
- Slow cooker style: Brown the sausage and onion first, then cook the soup base on low for 6 hours. Add the noodles during the final 30 minutes.
Make Ahead Tips
This is a great one for busy weeks. You can prep most of it before the day even starts.
- Cook the sausage, onion, garlic, tomatoes, and broth up to 3 days ahead. Store it in the fridge and stop before adding the noodles.
- Mix the ricotta topping the night before.
- Reheat the base until simmering, then add the noodles and cook fresh. Dinner is ready in about 15 minutes.
Cooking the noodles fresh matters. It keeps them from turning mushy and drinking up all your broth.
Leftovers and Storage
Here is a heads up. The noodles keep soaking up liquid as the soup sits, so leftovers turn thicker.
- Fridge: Store in an airtight container for up to 4 days. Keep the ricotta topping in a separate container.
- Freezer: Freeze the soup base without noodles for up to 3 months. Thaw overnight in the fridge and cook fresh noodles when you reheat.
- Reheating: Warm the soup in a pot over medium-low heat and stir in a splash of broth or water to loosen it. A microwave works too, just heat in short bursts and stir between each one.

What to Serve With Lasagna Soup
This soup is filling on its own, but a simple side makes it feel like a full Italian dinner.
- Garlic bread for dunking (this is not optional in my house)
- A crisp Caesar or arugula salad
- Crusty bread with olive oil
- Roasted broccoli with lemon
A green salad works best if you want something fresh to balance all that cheesy goodness.
FAQ Related to Italian Sausage Lasagna Soup
1. Can I make lasagna soup without ricotta?
Yes. Cottage cheese, mascarpone, or a little cream cheese stirred into the soup all give you that creamy lasagna feel.
2. What noodles are best for lasagna soup?
Mafalda noodles, also called mini lasagna noodles, are the easiest choice because they have ruffled edges and fit on a spoon. Regular lasagna noodles broken into pieces work great too.
3. Can I freeze lasagna soup?
You can. Freeze the soup base without the noodles, since pasta turns soft and mushy after thawing. Add fresh noodles when you reheat.
4. How do I keep the soup from getting too thick?
Add an extra cup of broth if the noodles soak up too much, especially when reheating leftovers.
5. Is lasagna soup gluten free?
Not as written, because of the noodles. Use gluten free pasta and check that your sausage and broth are labeled gluten free.
6. Can I use a slow cooker or Instant Pot?
Yes to both. Brown the sausage and onion on the stove first for the best flavor, then finish in your appliance. Add the noodles near the end so they do not overcook.
Wrapping Up
If you want a bowl of comfort food that feels special without the fuss, this Italian sausage lasagna soup is the one to make. It is hearty, cheesy, and ready before your oven would have even finished preheating for a full lasagna.
