Quick White Lasagna Soup

Quick white lasagna soup is one of those recipes I keep coming back to on cold nights when I want something warm and satisfying without standing over the stove for an hour. It pulls every classic flavor from white lasagna – savory Italian sausage, creamy broth, tender noodles, and melted cheese – into one cozy bowl that comes together in a single pot.

I made this for the first time on a particularly cold winter night when I had half a pound of Italian sausage left and a box of lasagna noodles I kept ignoring. The smell of garlic hitting that hot pot was enough to bring everyone into the kitchen without being called. What I love most about this creamy lasagna soup is how it tricks people into thinking you did something complicated. Short ingredient list, one pot, and real Italian comfort food flavor. It has been a weeknight staple ever since.

Everything You Need to Make This Cozy Bowl

I always recommend pulling all your ingredients out before you start cooking – it makes the process feel effortless. Pro tip: choose a quality Italian sausage because it is the flavor foundation of this entire quick white lasagna soup.

• 1 tablespoon olive oil
• 1 pound Italian sausage, casings removed (mild is great for families, hot sausage works perfectly for spice lovers)
• 1 medium onion, diced
• 3 cloves garlic, minced (fresh cloves only – the flavor difference is worth the extra minute of prep)
• 4 cups chicken broth (low-sodium is preferred so you can control the salt level)
• 1 cup heavy cream
• 1 (15-ounce) can tomato sauce
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 1/2 teaspoon red pepper flakes – optional but recommended for gentle background heat
• 8 ounces lasagna noodles, broken into rough 2-inch pieces
• 1 cup shredded mozzarella cheese – divided into two equal portions
• 1/2 cup grated Parmesan cheese
• Fresh basil for garnish – optional

Pro tip: Swapping half the chicken broth for beef broth adds a deeper, more savory backbone to the soup. It is a small change that makes the broth taste like it simmered much longer than it did.

How to Make Quick White Lasagna Soup Step by Step

I recommend a large Dutch oven or heavy-bottomed pot for this recipe. It holds heat evenly and gives the soup enough room to bubble gently without boiling over.

Step 1 – Brown the sausage. Heat the olive oil over medium-high heat. Add the Italian sausage and break it into crumbles with a wooden spoon. Cook for 5-7 minutes until the meat is fully browned with a little golden color on the edges. Leave a small amount of the rendered fat in the pot – it carries flavor into the broth.

Step 2 – Soften the aromatics. Add the diced onion directly into the pot with the sausage. Stir and cook for about 5 minutes until the onion turns translucent and softens. Add the minced garlic and stir for one minute until fragrant. Watch the garlic closely here – it burns fast and turns bitter if it sits too long on high heat.

Step 3 – Build the broth. Pour in the chicken broth, heavy cream, and tomato sauce. Stir well to combine everything. Add the dried oregano, dried basil, and red pepper flakes if using. Bring the soup to a gentle simmer over medium heat – this takes about 3-4 minutes. If the soup looks too thick at this stage, add an extra 1/2 cup of broth.

Step 4 – Add and cook the noodles. Add the broken lasagna noodle pieces directly to the simmering broth. Stir occasionally to prevent them from sticking together or to the bottom of the pot. Cook for 8-10 minutes until the noodles are al dente – tender with just a slight chew. Pull them a minute early since they continue softening as the soup sits.

Step 5 – Melt in the cheese. Reduce the heat to low. Stir in half the mozzarella and all of the Parmesan. Stir gently until both cheeses are fully melted and the broth looks creamy and thick. Do not let the soup return to a boil after adding the cheese – high heat causes dairy-based broth to break and turn grainy.

Step 6 – Serve immediately. Ladle the quick white lasagna soup into bowls while hot. Top each bowl with the remaining shredded mozzarella so it melts on contact with the hot soup. Add fresh basil leaves if you like a pop of color and brightness.

The Best Ways to Serve This Creamy Weeknight Soup

This rich, cheesy soup pairs naturally with simple sides that balance its creamy Italian flavors. Here are the best sides for quick white lasagna soup:

Garlic Bread: The crunch of a toasted garlic baguette is a perfect contrast to the silky broth. Use it to scoop up the cheesy noodles and soak up every last drop.

Crusty Italian Bread: A thick slice of rustic Italian bread holds up well for dipping without falling apart in the bowl. The chewy texture complements the soft noodles nicely.

Simple Green Salad: A crisp romaine or arugula salad with lemon vinaigrette cuts through the richness of the soup and keeps the overall meal feeling balanced and light.

Ricotta Dollop: Drop a generous spoonful of whole-milk ricotta directly into each bowl before serving. It melts slightly into the broth and adds that extra layer of creaminess that makes this taste like true white lasagna.

Roasted Broccoli: A side of oven-roasted broccoli adds a nutritious green element with a slight char that plays well against the savory sausage in the broth.

Storing and Reheating Your Leftovers Like a Pro

This quick white lasagna soup stores well and the flavor deepens overnight as everything continues to meld together. Keep leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze in a freezer-safe container for up to 3 months. Note that the pasta will soften more after freezing. If you plan to freeze a batch, slightly undercook the noodles at Step 4 so they hold up better after thawing.

To reheat, warm the soup on the stovetop over medium-low heat, stirring gently. The noodles will have absorbed liquid during storage, so add a splash of chicken broth or a little cream to loosen it back to your preferred consistency. Avoid high heat during reheating – it can cause the cream base to separate and turn oily.

Pro tip: If you regularly batch cook or meal prep, store the cooked noodles in a separate container from the soup base. Add noodles to each bowl at serving time. This one habit keeps the texture fresh all week and prevents the pasta from turning to mush.
