Lasagna soup is all over my feed, and after one spoonful you'll understand why. You get saucy meat-and-tomato lasagna flavor, tender broken noodles, and a creamy ricotta dollop on top without layering a single thing.

It's a true one-pot dinner: the pasta cooks right in the broth, so the starch thickens the soup into something silky and almost stew-like. I keep the ricotta topping cold and tangy so it melts into the hot soup as you eat.
My version leans on Italian sausage for built-in seasoning and a splash of heavy cream at the end to make it feel rich without being heavy. From a weeknight to a game-day pot, it works.
Why You'll Love This Recipe
About the Ingredients
1 lb (450g) hot or mild Italian sausage, casings removed
Bulk sausage packs more fennel flavor than links you have to peel. Swap in ground beef plus 1 teaspoon fennel seed if sausage isn't available.
1 medium yellow onion, diced (about 1 cup)
Yellow onion gives the sweetest base; white or sweet onion works too. Skip red onion here, it turns the broth pink.
3 garlic cloves, minced
Fresh garlic is worth it; jarred tastes flat after simmering. Use 1 teaspoon garlic paste in a pinch.
2 tablespoons tomato paste
Tomato paste adds deep, roasted sweetness. Buy it in a tube so you don't waste a can.
1 (28 oz / 800g) can crushed tomatoes
Crushed tomatoes give body without chunks. San Marzano-style cans are sweeter and less acidic.
6 cups (1.4L) low-sodium chicken broth
Low-sodium lets you control the salt since the sausage and parmesan are salty. Vegetable broth makes it work for a meatless swap.
8 oz (225g) lasagna noodles, broken into 1- to 2-inch pieces
Regular (not no-boil) noodles hold up best and release starch to thicken the soup. Campanelle or mafaldine are good stand-ins.
1 teaspoon dried oregano and 1/2 teaspoon red pepper flakes
Oregano is the classic lasagna herb; basil works if that's what you have. Adjust pepper flakes to your heat tolerance.
1/2 cup (120ml) heavy cream
Cream rounds out the acidity. Half-and-half or whole milk works, but add it off the heat so it doesn't curdle.
1 cup (250g) whole-milk ricotta
Whole-milk ricotta is creamier and less grainy. Drain it briefly if it looks watery.
1/2 cup (50g) grated parmesan, plus more for serving
Freshly grated parmesan melts better than the shaker kind. Pecorino is a sharper swap.
1/4 cup torn fresh basil, plus more for serving
Add basil at the end so it stays bright. Frozen basil cubes or a teaspoon of pesto work off-season.
Tips & Tricks
Break the noodles small
Pieces bigger than 2 inches keep cooking and turn mushy in leftovers. Snap them into 1- to 2-inch shards before they hit the pot.
Stir the bottom often
The starch from the pasta loves to stick. Scrape the bottom of the pot every few minutes during the simmer.
Add cream off the heat
Boiling cream with acidic tomatoes can curdle. Stir it in after you pull the pot off the burner.
Thin leftovers with broth
The soup thickens a lot as it sits. Add a splash of broth when reheating instead of water for more flavor.
Pro Tips
Step-by-Step Instructions
1. Brown the sausage
Heat a Dutch oven over medium-high heat (about 400F / 205C surface) and cook the sausage, breaking it up, for 6 to 8 minutes until no pink remains and the edges are golden brown. Spoon off all but 1 tablespoon of fat.
2. Soften the aromatics
Add the onion and cook 4 to 5 minutes until translucent and soft. Stir in the garlic, tomato paste, oregano, and red pepper flakes and cook 60 seconds until the paste smells sweet and turns brick red.
3. Build the broth
Pour in the crushed tomatoes and chicken broth, scraping up the browned bits. Bring to a boil over high heat, then reduce to a steady simmer (about 200F / 93C) and cook 10 minutes so the flavors meld.
4. Cook the noodles
Stir in the broken lasagna noodles and simmer 12 to 14 minutes, stirring often, until al dente and the broth has thickened enough to coat a spoon. Taste a noodle; it should have a slight bite in the center.
5. Finish with cream
Pull the pot off the heat and stir in the heavy cream and half the parmesan. Taste and add salt and pepper; the broth should be silky and taste slightly bright from the tomato.
6. Mix the ricotta topping
In a small bowl, stir the ricotta with the remaining parmesan and a pinch of salt and pepper until smooth. Keep it chilled until serving.
7. Serve hot
Ladle the soup into bowls and top each with a generous spoonful of ricotta, torn basil, and extra parmesan. Serve right away while the cheese is cold against the hot broth.
Delicious Variations
Meatless Mushroom
Swap the sausage for 12 oz (340g) cremini mushrooms browned in olive oil and use vegetable broth.
Spicy Vodka Style
Add 1/4 cup vodka with the tomatoes and a pinch more red pepper flakes for a fiery, restaurant-style bowl.
White Lasagna Soup
Skip the crushed tomatoes and use 1 cup whole milk plus extra parmesan for a creamy white lasagna flavor.
How to Store Viral Lasagna Soup
Refrigerator
Store in an airtight container up to 4 days. The noodles will absorb broth, so loosen with extra broth when reheating.
Freezer
Freeze the soup base without the cream, ricotta, or noodles up to 3 months. Thaw overnight in the fridge, then simmer with fresh noodles and finish with cream.
Reheating
Reheat gently on the stovetop over medium-low heat (about 300F / 150C) for 5 to 7 minutes, adding broth as needed. Avoid a hard boil, which can break the noodles.
Frequently Asked Questions
Q: Can I use regular lasagna noodles in lasagna soup?
Yes, regular dry lasagna noodles are the best choice; break them into 1- to 2-inch pieces and simmer them right in the broth. Avoid no-boil noodles, which turn gummy in soup.
Q: Why did my lasagna soup turn out mushy?
The noodles were likely cooked too long or the soup sat with pasta in it. Cook noodles just to al dente and store leftovers with the pasta separate if you can.
Q: Can I make lasagna soup in a slow cooker?
Yes, brown the sausage and aromatics on the stove first, then add everything except the noodles, cream, and ricotta to a slow cooker on low for 4 hours. Add the noodles in the last 30 minutes on high.
Q: How do I keep the cream from curdling in lasagna soup?
Stir the cream in after you take the pot off the heat, and use heavy cream rather than milk. The fat content protects it from the acidic tomatoes.
Q: Is lasagna soup gluten-free?
It can be if you use gluten-free lasagna noodles and gluten-free broth. Add the GF noodles in the last 8 to 10 minutes since they cook faster and break down easily.
