If you love baked pasta but not the layering, this lasagna soup is your new weeknight hero. Italian sausage, garlic, tomatoes and ruffled noodles simmer together in one pot, then each bowl gets a creamy spoonful of ricotta and a blanket of melted mozzarella. It tastes remarkably like the real thing.
In this post I explain why the soup works, what to buy, how to make it step by step, how to serve it, easy swaps, common mistakes and how to store leftovers. The printable recipe card with exact measurements and estimated nutrition is waiting at the bottom of the post.
Why This Lasagna Soup Recipe Works
Lasagna has a few signature flavors: a meaty tomato sauce, plenty of garlic and herbs, wide noodles and a cloud of creamy cheese. This soup captures every one of them in a fraction of the time.
- Everything cooks in one pot. You brown the sausage, build the broth and cook the noodles right in the soup, so cleanup is easy.
- The noodles season the broth. Broken lasagna noodles release a little starch as they cook, giving the soup a silky body.
- Tomato paste adds depth. Cooking it with the sausage for a minute turns it brick red and rich instead of raw and sharp.
- The cheese goes on top. Ricotta and mozzarella are added at the end so they stay creamy and stretchy instead of melting away.
It is a great option for a chilly fall night, a casual Halloween dinner before trick-or-treating on Saturday, October 31, or any time you want Italian comfort food with minimal fuss.
Ingredients You Will Need
Nothing here is hard to find, and most of it lives in the pantry. Here is what goes into the pot and why.
- Italian sausage: One pound (450 g) of mild or hot bulk sausage gives built-in seasoning. Ground beef also works.
- Onion and garlic: The savory base for the soup.
- Tomato paste: Adds concentrated flavor and a little body.
- Crushed tomatoes and marinara: Together they give a sauce that is thick but still spoonable.
- Beef or chicken broth: Low sodium is best, so you control the salt.
- Dried basil, oregano and red pepper flakes: The classic lasagna seasonings.
- Lasagna noodles: About 8 dry noodles, broken into pieces. Mafalda corta or bow ties also work.
- Ricotta, mozzarella and Parmesan: The creamy, cheesy finish that makes this taste like lasagna.
If you want a touch of richness, stir a half cup of heavy cream into the pot at the end for a creamier, tomato-bisque style soup.
When shopping, look for crushed tomatoes without added seasoning, so the herbs in the recipe shine. A jar of good marinara adds extra depth, but a basic store brand works fine because the sausage and garlic do plenty of work.
How to Make Lasagna Soup
Total hands-on time is about 20 minutes. The soup simmers while you mix the ricotta topping.
Use a pot that is wide and at least 5 quarts, which gives the noodles room to move and keeps the soup from boiling over.
- Brown the sausage. Cook the sausage and onion in a large Dutch oven over medium-high heat, breaking up the meat, until no pink remains and it reaches 160°F (71°C), about 7 minutes. Drain excess fat if there is a lot.
- Add the aromatics. Stir in the garlic and tomato paste and cook for 1 minute, stirring, until fragrant and darkened.
- Build the soup. Add the crushed tomatoes, marinara, broth, basil, oregano, red pepper flakes, salt and pepper. Bring to a boil.
- Cook the noodles. Break the lasagna noodles into 1 to 2 inch pieces and stir them in. Reduce the heat to a simmer and cook, stirring often, for 12 to 14 minutes until tender.
- Mix the topping. Stir together the ricotta, Parmesan, parsley and a pinch of salt in a small bowl.
- Serve. Ladle the soup into bowls, add a dollop of ricotta mixture, sprinkle with mozzarella and finish with basil. Let the cheese melt for a minute before eating.
If the soup gets too thick while the noodles cook, add a splash of broth or water. Pasta keeps absorbing liquid even after you turn off the heat.
Choosing the Best Noodles
Standard dry lasagna noodles, broken into irregular pieces, give the most authentic look and bite. They are sturdy, so they hold up well in a hot broth.
- Regular lasagna noodles: Break them by hand into rustic pieces. Do not boil them first.
- Mafalda corta: These mini ruffled ribbons look like tiny lasagna noodles and need no breaking.
- Bow tie pasta or rotini: Good pantry swaps with similar cooking times.
- Gluten free noodles: Use a sturdy brand and check the package time, since they often cook faster.
Avoid very thin pasta like angel hair, which goes soft quickly and can turn the soup mushy.
Once the noodles are in, keep the pot at a gentle simmer rather than a hard boil. A calm simmer cooks the pasta evenly and keeps the sausage tender, while a rolling boil can break the noodles apart and splash sauce across the stove.
Tips for the Best Lasagna Soup
- Break the noodles small. Spoon-sized pieces are easier to eat and cook more evenly.
- Stir often. Noodles sink and stick to the bottom of the pot if you leave them alone.
- Season at the end. Broth, sausage and cheese all contain salt, so taste before adding more.
- Use freshly shredded mozzarella. It melts more smoothly than pre-shredded cheese coated with anti-caking starch.
- Keep the ricotta cold. A cool dollop against hot soup creates the contrast that makes each spoonful exciting.
If you love Italian flavors, my classic beef lasagna with layers of meat sauce is the traditional version. For another cozy pot, try the one pot creamy sausage pasta, or browse all my soup and stew recipes.
Lasagna Soup vs. Classic Lasagna
Traditional lasagna is wonderful, but it asks for a lot: a long simmered sauce, boiled noodles, layers to assemble, an oven preheat and then a rest before slicing. Easy lasagna soup keeps the flavors and drops most of the steps, which is why it has become one of my go-to weeknight pots.
- Time: The soup is on the table in about 45 minutes, while a casserole can take well over two hours from start to finish.
- Dishes: One pot and a small bowl for the ricotta replace the pasta pot, skillet, mixing bowl and baking dish.
- Portions: Soup is easy to stretch with extra broth or a few more noodles if unexpected guests show up.
- Leftovers: Both reheat well, but soup is easier to portion for packed lunches.
That said, nothing replaces a bubbling pan of layered lasagna for a holiday table. I make the soup when I want the flavor without the project.
Easy Variations
- Ground beef lasagna soup: Replace the sausage with lean ground beef and add an extra teaspoon of Italian seasoning.
- Turkey sausage version: Use turkey sausage or ground turkey and cook it to 165°F (74°C).
- Veggie loaded: Add diced zucchini, mushrooms or a few handfuls of baby spinach in the last 5 minutes.
- Creamy lasagna soup: Stir in 1/2 cup of heavy cream or cream cheese after the noodles are tender.
- Spicy soup: Use hot Italian sausage and double the red pepper flakes.
- Slow cooker style: Cook everything except the noodles on low for 6 hours, then add broken noodles and cook on high for 20 to 30 minutes.
What to Serve with Lasagna Soup
Garlic bread is the natural partner, and it is perfect for scooping up the last of the broth. A crisp green salad with a tangy Italian vinaigrette balances the richness of the cheese.
For a bigger spread, add a bowl of my fall harvest salad on the side. Leftover soup also makes a fun lunch with a grilled cheese sandwich for dipping.
Common Mistakes and How to Fix Them
Lasagna soup is straightforward, but a few details make the difference between a silky bowl and a stodgy one. Here are the issues I see most often.
| Problem | Likely cause | How to fix it |
|---|---|---|
| Mushy noodles | Cooked too long or left sitting in the soup | Cook just until tender and serve right away, or cook noodles separately for leftovers |
| Soup too thick | Noodles absorbed the broth | Stir in warm broth or water a little at a time |
| Bland flavor | Not enough salt, herbs or acid | Season at the end and add a splash of balsamic or extra Parmesan |
| Grainy ricotta | Part-skim ricotta or overheating | Use whole milk ricotta and add it to the bowl, not the pot |
| Greasy broth | Fatty sausage not drained | Drain the fat or skim it off the top before adding noodles |
Make Ahead, Storage and Reheating
Refrigerate leftover soup in airtight containers within 2 hours of cooking and eat it within 3 to 4 days. The USDA explains these timelines in its guide to leftovers and food safety. Reheat the soup until it is steaming hot, 165°F (74°C).
The noodles keep drinking broth in the refrigerator, so leftovers will be thicker. Add a splash of broth when you reheat. For the best texture, store the ricotta topping and mozzarella separately and add them fresh to each bowl.
To freeze, make the soup without the noodles and freeze it for up to 3 months. Thaw overnight in the refrigerator, bring it to a simmer, then cook fresh broken noodles in it until tender.
Frequently Asked Questions
Do I have to cook the lasagna noodles first?
No. Break dry noodles into pieces and simmer them directly in the soup for 12 to 14 minutes. They cook and thicken the broth at the same time.
Can I make lasagna soup without ricotta?
Yes. Stir in cream cheese or mascarpone, or top each bowl with extra mozzarella and Parmesan. Cottage cheese blended smooth is another option.
Can lasagna soup be made ahead?
Yes, it keeps well for 3 to 4 days in the refrigerator. The noodles will absorb broth, so add a splash of liquid when reheating.
Can I freeze lasagna soup?
Freeze the soup base without noodles for up to 3 months. Cook fresh noodles in it after thawing so they do not turn soft.
What can I use instead of Italian sausage?
Lean ground beef, ground turkey or ground chicken all work. Add an extra teaspoon of Italian seasoning and a pinch of fennel seeds for sausage-like flavor.
