Ingredients You’ll Need

- 1/2 lb ground sausage: Adds a hearty, flavorful protein base with a bit of spice and richness.
- 1 small onion, chopped: Brings sweetness and depth of flavor as it softens and caramelizes.
- 8 ounces mushrooms, sliced: Offer an earthy, meaty texture that complements the sausage beautifully.
- 2 cloves garlic, minced: A punch of aromatic warmth that elevates the entire dish.
- 4 cups baby spinach: Adds vibrant color and freshness, balancing the richness.
- 5 cups low sodium chicken broth: Forms the savory liquid base of the soup, keeping flavors bright and balanced.
- 5 lasagna noodles, broken: The star pasta element, tender and perfectly noodle-shaped for spoonfuls of comfort.
- 1 teaspoon dried oregano: Infuses a classic Italian herbaceous note to the broth.
- 1/2 teaspoon dried basil: Adds a sweet, subtle hint of fragrant basil for authenticity.
- 3 tablespoons butter: Essential for making the creamy Alfredo sauce, enriching the soup.
- 3 tablespoons flour: Helps thicken the sauce to the perfect velvety texture.
- 1 cup milk: Provides the creamy liquid base for the Alfredo flavor without overpowering the other ingredients.
- 1 cup Parmesan, grated: Melts into the sauce creating that signature tangy, salty creaminess that makes Alfredo irresistible.
How to Make Creamy Alfredo Lasagna Soup Recipe
Step 1: Brown the Sausage and Sauté the Veggies
Start by browning the ground sausage in a large saucepan over medium heat until it’s beautifully caramelized and fragrant. This step is key for building the savory base of your soup. Once browned, toss in the chopped onions and sliced mushrooms and cook over medium-low heat for about 5-6 minutes. These vegetables will soften and marry their flavors with the sausage, creating a rich, hearty foundation.
Step 2: Add Garlic and Spinach
Next, add the minced garlic and baby spinach to the pot. Stir constantly for about a minute until the garlic releases its aroma and the spinach wilts just enough to blend into the mix. This layer of freshness and bold garlicky flavor will brighten up the richness ahead.
Step 3: Pour in the Chicken Broth and Simmer
Pour the low sodium chicken broth into the saucepan. This will bring everything together, turning your sautéed ingredients into a flavorful broth. Let it simmer gently for five minutes—this short simmering helps all the flavors marry beautifully without overwhelming the fresh notes.
Step 4: Add Noodles and Herbs
Throw in the broken lasagna noodles along with dried oregano and basil. Bring the soup to a low boil and cook for 10-12 minutes or until the noodles are perfectly tender. Those herbs add a subtle, authentic Italian twist that feels like dinner at an Italian trattoria.
Step 5: Make the Creamy Alfredo Sauce
While the noodles cook, melt butter in a separate skillet over medium-low heat. Whisk in the flour and keep whisking for about a minute until the mixture bubbles slightly—this is your roux, the magic thickener. Gradually pour in the milk while continuously whisking to avoid clumps. Keep whisking for 3-5 minutes until the sauce thickens and becomes delightfully smooth.
Step 6: Incorporate Parmesan Cheese
Turn off the heat and gently whisk in the grated Parmesan cheese. If it resists melting, place the pan over very low heat and whisk constantly until it melts completely. This step is crucial to develop that signature creamy Alfredo texture and flavor. Once perfectly creamy, slowly whisk this sauce into your soup base until fully combined and luscious.
How to Serve Creamy Alfredo Lasagna Soup Recipe

Garnishes
Top your soup with freshly chopped parsley or a sprinkle of extra Parmesan for a beautiful, vibrant finish. A drizzle of good olive oil or a pinch of red pepper flakes can add some unexpected flair and complexity.
Side Dishes
This soup pairs wonderfully with garlic bread or warm crusty bread to soak up every bit of that creamy broth. A crisp green salad on the side can brighten the meal and round out the flavors with a refreshing crunch.
Creative Ways to Present
Serve this Creamy Alfredo Lasagna Soup Recipe in rustic bowls with a breadstick perched on top for a charming touch. For a fun twist, add a swirl of pesto or a dollop of ricotta cheese for extra creaminess and hints of herbaceous richness that will impress your guests.
Make Ahead and Storage
Storing Leftovers
This soup stores beautifully in an airtight container in the refrigerator for up to 3 days. As the noodles absorb broth over time, you might want to add a splash of chicken broth or milk when reheating to keep the texture perfect.
Freezing
You can freeze Creamy Alfredo Lasagna Soup Recipe in portioned containers for up to 2 months. Keep in mind the noodles may soften slightly once thawed, so it’s best to freeze if you plan to enjoy within that timeframe.
Reheating
Reheat gently over low heat on the stove, stirring frequently to prevent sticking and ensure even warming. Adding a little extra broth or milk can restore the soup’s creamy consistency and fresh flavor.
FAQs
Can I use a different type of sausage?
Absolutely! Italian sausage is traditional here, but spicy chorizo or even turkey sausage can work well, altering the flavor profile while keeping the heartiness intact.
Is there a vegetarian version of this soup?
Yes, you can skip the sausage and use extra mushrooms or plant-based sausage alternatives. Just boost the flavor with vegetable broth and extra herbs for a satisfying vegetarian option.
Can I make this soup dairy-free?
To make this dish dairy-free, substitute the butter with a plant-based spread, use a dairy-free milk alternative, and swap Parmesan for a nut-based cheese or nutritional yeast for that cheesy flavor.
How thick should the Alfredo sauce be?
The sauce should be rich and smooth, thick enough to coat the back of a spoon but still pourable so it blends nicely into the soup, making it velvety without heaviness.
Can I use no-boil lasagna noodles?
It’s best to use regular lasagna noodles broken into pieces since they cook directly in the broth, becoming tender as the soup simmers. No-boil noodles won’t soften properly in this soup setting.
