How to Make Decadent Creamy Alfredo Lasagna Soup

Step 1: Sauté the Garlic in Butter

Start by melting your butter in a large pot over medium heat. Once it’s bubbling, add the garlic and gently sauté for just a minute or two. Watch for that heavenly aroma—this step is what brings the soup’s base to life and infuses everything with cozy, inviting flavor.

Step 2: Create the Golden Roux

Sprinkle in the flour and stir continuously until it combines with the butter and begins to turn a pale, toasty gold. This part may seem simple, but it’s the secret to getting the soup luxuriously thick and creamy—no watery broth here!

Step 3: Whisk in the Chicken Broth

Gradually pour in the chicken broth while whisking constantly, smoothing out any lumps as you go. You’ll see the mixture turn silky and glossy in just a minute or two—this is your rich, savory canvas for all the cheesy magic to come.

Step 4: Add Cream and Seasonings

Pour in the heavy cream, followed by the Italian seasoning, salt, and pepper. Let it come to a gentle simmer for about 5 minutes. The herbs bloom in the warmth, filling your kitchen with those familiar, comforting Italian scents that hint at what’s to come.

Step 5: Stir in the Cheeses

Reduce the heat and add in the Parmesan and mozzarella cheeses, stirring until everything melts together into a decadent, smooth soup base. This is where Decadent Creamy Alfredo Lasagna Soup gets its signature richness, with all the gooey, cheesy flavor of a perfect white lasagna.

Step 6: Fold in the Pasta

Gently add your cooked rigatoni or pieces of lasagna noodles, stirring to coat each piece with creamy sauce. Let the soup warm through for a minute—just enough for the pasta to soak up all that flavor before serving.

Step 7: Serve and Top to Finish

Ladle the soup into bowls and finish with a generous shower of toasted breadcrumbs and a scattering of fresh herbs. Instantly, you’ve transformed your kitchen into the coziest bistro in town!

How to Serve Decadent Creamy Alfredo Lasagna Soup

Garnishes

You can’t go wrong by topping Decadent Creamy Alfredo Lasagna Soup with extra cheese, a tumble of golden toasted breadcrumbs, and a sprinkle of chopped parsley or basil. Not only does it look stunning, but it adds a fantastic contrast of textures and a pop of freshness to every spoonful.

Side Dishes

Pair your soup with classic Italian sides for a complete meal. Warm, crusty garlic bread or a crisp, tangy Caesar salad are both wonderful options that complement the richness of the soup. For extra coziness, serve with roasted vegetables or an antipasto platter overflowing with olives and marinated veggies.

Creative Ways to Present

Try ladling Decadent Creamy Alfredo Lasagna Soup into oven-safe bowls, then sprinkle with mozzarella and broil for a bubbly, cheesy crust. Or, serve in small cups as a chic appetizer at your next dinner party. You could even top each bowl with a swirl of pesto or a drizzle of chili oil for a gourmet twist.

Make Ahead and Storage

Storing Leftovers

Store any leftover soup in an airtight container in the refrigerator for up to three days. As the soup sits, it may thicken—simply stir in a splash of broth or cream as you reheat to make it silky again.

Freezing

Although this soup is at its dreamy best when fresh, you can freeze it! Let it cool completely, then transfer to freezer-safe containers. Freeze for up to 2 months. To prevent the pasta from getting mushy, consider freezing without the noodles, then adding freshly cooked pasta when you’re ready to enjoy.

Reheating

Gently reheat the soup on the stovetop over medium-low heat, stirring often to avoid scorching the bottom. If it’s thicker than you’d like, add a splash of broth or milk to loosen it up. You can also microwave single servings—just go slow and stir halfway through.

FAQs

Can I make Decadent Creamy Alfredo Lasagna Soup vegetarian?

Absolutely! Simply swap the chicken broth for vegetable broth, and you’ll have a luscious, meatless version that everyone can enjoy. All those flavors still shine through beautifully.

What type of pasta works best in this soup?

Rigatoni is my top pick for those satisfying, hearty bites, but you can also break sheet lasagna noodles into pieces for the classic lasagna vibe—or use whatever pasta shape you have in your pantry.

How do I toast breadcrumbs for the topping?

Just add a drizzle of olive oil to a skillet, toss in the breadcrumbs, and cook over medium heat until they’re golden and crisp. Keep them moving in the pan so they don’t burn!

Can I add meat to the soup?

Yes! Feel free to stir in sautéed chicken, cooked Italian sausage, or even bits of cooked bacon for an extra layer of heartiness and flavor—anything you’d love tucked into a traditional white lasagna.

Will Decadent Creamy Alfredo Lasagna Soup thicken as it cools?

It will thicken slightly as it stands, thanks to the pasta and cheeses. If it gets too thick, just add a splash of broth or milk and stir well as you heat it up again.
