There is a particular hour in late autumn when the light turns thin and gray, and the only sensible answer is a pot of something that smells like a Sunday kitchen. This is that pot. The broth simmers with sausage and tomato until the whole house seems to lean toward the stove, and the noodles go in at the very end so they stay tender without turning to paste.
Each ingredient has a job here. The Italian sausage lays down the savory base, the tomato paste deepens it into something almost sweet, and the broken lasagna noodles drink up the broth so every spoonful feels like a full bite of lasagna. The ricotta-and-mozzarella dollop on top is not decoration; it melts into the hot soup and makes the whole bowl taste creamy without thinning the broth.
I like to stir the basil in off the heat, when the pot is still steaming, so the scent rises rather than cooks away. Ladle it into deep bowls, add the cheese, and let everyone stir their own. Take your time, and taste as you go.
Why You'll Love This Recipe
About the Ingredients
1 lb (450 g) mild or hot Italian sausage, casings removed
Buy sausage with visible fennel seed for the most fragrant base. Ground beef mixed with 1 teaspoon fennel seed works if sausage is unavailable.
1 medium yellow onion, finely diced (about 1 cup / 160 g)
Yellow onion gives the sweetest, softest base; white onion is sharper but fine. Frozen diced onion (about 1 cup) saves ten minutes on a busy night.
4 garlic cloves, minced
Fresh garlic is worth it here; jarred minced garlic tastes flatter. Add it last so it smells sweet rather than bitter.
3 tablespoons tomato paste
Look for paste in a tube so you can use only what you need. Sun-dried tomato paste is a richer swap if you have it.
1 can (28 oz / 800 g) crushed tomatoes
Crushed tomatoes give body without chunks; whole tomatoes crushed by hand are more rustic. Choose a brand with no added sugar.
6 cups (1.4 L) low-sodium chicken broth
Low-sodium lets you control the salt at the end. Vegetable broth makes this fully meatless-friendly if you also swap the sausage.
8 oz (225 g) lasagna noodles, broken into 2-inch pieces
Regular lasagna sheets break cleanly with your hands. No-boil sheets work but need 3 extra minutes of simmering.
1 teaspoon dried oregano and 1/2 teaspoon red pepper flakes
Oregano is the dried herb that tastes most like lasagna. Crush it between your palms before adding to wake it up.
1 cup (250 g) whole-milk ricotta
Whole-milk ricotta is creamier and less watery; drain it briefly if it looks loose. Cottage cheese blended smooth is a lighter substitute.
1 cup (100 g) shredded low-moisture mozzarella
Low-moisture mozzarella melts without releasing water. Fresh mozzarella will make the topping soupy, so save it for another use.
1/3 cup (30 g) grated Parmesan, plus more for serving
Buy a wedge and grate it yourself; pre-grated Parmesan is drier. Pecorino Romano is sharper and saltier, so use a little less.
1/4 cup torn fresh basil, plus salt and black pepper to taste
Torn basil releases more aroma than chopped. Frozen basil cubes or a pinch of dried basil work out of season.
Tips & Tricks
Break the noodles short
Two-inch pieces cook evenly and fit on a spoon; long shards clump and stay firm in the center.
Simmer gently, never boil
A hard boil makes the noodles shed starch and the broth turn gluey. Keep it at a lazy bubble.
Season at the end
The sausage, Parmesan, and broth all carry salt, so taste before adding more.
Thin it as it sits
The noodles keep drinking broth; loosen leftovers with a splash of hot broth or water.
Pro Tips
Step-by-Step Instructions
1. Brown the sausage
Heat a large Dutch oven over medium-high heat (about 400°F / 205°C surface) for 2 minutes, then add the sausage and cook 6 to 8 minutes, breaking it up, until no pink remains and the edges are golden brown. The sizzle should be steady, not violent.
2. Soften the aromatics
Lower the heat to medium (about 350°F / 175°C) and add the onion. Cook 5 minutes, stirring, until translucent and soft, then add the garlic and cook 45 seconds, just until fragrant.
3. Bloom the tomato paste
Stir in the tomato paste, oregano, and red pepper flakes and cook 1 minute, until the paste darkens to brick red and smells sweet rather than sharp. This step builds the lasagna depth.
4. Build the broth
Pour in the crushed tomatoes and chicken broth, scraping the browned bits from the bottom. Bring to a gentle boil, then lower to a simmer (about 200°F / 93°C) and cook 10 minutes, until the broth thickens slightly and tastes rounded.
5. Cook the noodles
Add the broken lasagna noodles and simmer 12 to 14 minutes, stirring every few minutes, until tender with a slight bite at the center. The broth should look slightly cloudy and cling to the noodles.
6. Mix the cheese topping
While the noodles cook, stir together the ricotta, half the mozzarella, the Parmesan, and a pinch of black pepper in a small bowl. It should look thick and scoopable.
7. Finish with basil
Turn off the heat, stir in the basil, and taste for salt and pepper. The pot should smell green and sweet at the edges of the tomato.
8. Serve with cheese
Ladle into deep bowls and top each with a generous spoonful of the ricotta mixture and the remaining mozzarella. Serve immediately, with extra Parmesan at the table.
Delicious Variations
Spicy Arrabbiata Version
Double the red pepper flakes and finish with a spoonful of chili oil for a sharper, hotter bowl.
Mushroom and Spinach
Swap the sausage for 12 ounces of cremini mushrooms and add 3 cups of spinach at the end for a meatless pot.
White Lasagna Soup
Replace the crushed tomatoes with 1 cup of whole milk and use basil pesto instead of dried oregano for a pale, creamy soup.
How to Store Viral Lasagna Soup
Refrigerator
Store in an airtight container for up to 3 days; the noodles will soften, so add a splash of broth when reheating.
Freezer
Freeze the soup without the ricotta topping for up to 2 months in portions; thaw overnight in the refrigerator.
Reheating
Warm gently on the stovetop over medium-low heat (about 300°F / 150°C) for 5 to 7 minutes, stirring, until steaming; add broth if it looks thick.
Frequently Asked Questions
Q: Can I use regular pasta instead of lasagna noodles?
Yes, use 8 ounces of broken mafaldine, campanelle, or rotini and start checking for doneness 2 minutes earlier. Any short pasta with ridges will hold the broth well.
Q: Why did my lasagna soup turn thick and gluey?
The noodles absorbed too much broth, usually because the pot boiled too hard or sat too long. Keep it at a gentle simmer and loosen leftovers with hot broth before serving.
Q: Can I make lasagna soup in a slow cooker?
Yes, brown the sausage and onion first, then add everything except the noodles and cheese to the slow cooker and cook on low for 4 hours. Add the noodles in the last 30 minutes on high so they do not overcook.
Q: Is lasagna soup gluten-free?
It can be, if you use gluten-free lasagna noodles and check that your broth and sausage are gluten-free. Add the gluten-free noodles closer to serving, as they break down faster.
Q: What do you serve with lasagna soup?
A crisp green salad and warm garlic bread are the classic pairings, since both soak up the broth. A simple bruschetta with olive oil also works well.
If you make this pot, I would love to hear how your kitchen smelled while it simmered. Leave a comment with the swaps you tried, and save the recipe for the next gray afternoon when dinner needs to feel like a hug.
