Ingredients You’ll Need

The beauty of this recipe is how incredibly simple but essential the ingredients are: each one adds its own character, from vibrant color to deep, savory flavor. Take a good look at the list below and feel free to personalize it, but trust me, these basics make this soup irresistible!

Olive oil: Adds a subtle, fruity base flavor and helps brown the sausage beautifully.
Ground Italian sausage: Brings spiced, savory richness that gives the soup its signature heartiness.
Onion: Provides sweetness and depth, forming the aromatic backbone.
Garlic: Melds with the onions for that essential Italian flair—don’t skimp!
Chicken broth: Forms the primary liquid foundation for a savory, seasoned base.
Water: Lightens up the soup, balancing richness without diluting the flavor.
Lasagna noodles: Breaking them creates the “lasagna” feel in each bite—no special tools needed, just snap them with your hands.
Heavy cream: The secret to that classic Alfredo silkiness and luscious mouthfeel.
Grated Parmesan cheese: Melts into the broth for salty, nutty depth—choose fresh Parm for best results.
Italian seasoning: Dried herbs like basil and oregano add warmth and complexity in every spoonful.
Salt and pepper: Essential for seasoning—taste and adjust along the way!
Fresh spinach: A pop of green that adds nutrition and a touch of earthiness.
Ricotta cheese: A creamy dollop on top brings luxurious texture and wonderful contrast.
Chopped fresh parsley: For garnish, it brightens and freshens up this cozy dish.

How to Make This

Step 1: Brown the Sausage

Start by heating olive oil in a big, heavy-bottomed pot over medium heat. Add the ground Italian sausage and cook it, breaking it apart with a wooden spoon as it browns. You’re looking for lovely caramelization here—the sausage should be deeply browned, which will help flavor the entire soup with savory goodness.

Step 2: Sauté the Aromatics

Once your sausage is browned and crumbly, toss in the chopped onion and minced garlic. Sauté this mixture until the onion turns soft and translucent, and your kitchen smells absolutely irresistible. These aromatics are the heart and soul of this soup.

Step 3: Add Broth and Water

Pour in the chicken broth and water, using your spoon to scrape up any flavor-packed bits from the bottom of the pot. Bring the mixture to a gentle simmer; this forms the canvas for your soup, infusing every bite with depth and coziness.

Step 4: Cook the Noodles

Break your lasagna noodles into jagged, rustic pieces and add them straight into the pot. Simmer gently, stirring occasionally, until the noodles are perfectly tender—about 10 minutes. This is when your kitchen really starts smelling like homemade lasagna!

Step 5: Stir in Cream and Cheese

Reduce the heat to low and pour in the heavy cream and grated Parmesan cheese. Sprinkle in the Italian seasoning and stir until everything is smooth and combined. Season generously with salt and pepper, then taste and adjust as needed—remember, this is your masterpiece!

Step 6: Add Spinach

Next, add the fresh spinach. The warmth of the soup wilts the leaves in just a minute or two, adding color and a welcome hint of earthiness. Stir gently to combine.

Step 7: Serve It Up with Ricotta and Parsley

Ladle this steaming Alfredo Lasagna Soup into bowls and top each serving with a generous dollop of ricotta cheese. Finish with a sprinkle of fresh chopped parsley, and watch everyone’s eyes light up at the table.

How to Serve This

Garnishes

The crowning touch for this soup is a big, creamy spoonful of ricotta on each bowl, followed by a shower of fresh parsley. If you’re feeling extra fancy, a grating of fresh Parmesan or a drizzle of good olive oil adds yet another pop of flavor. Don’t be shy with that ricotta: its cool, rich texture is what takes this from good to downright decadent.

Side Dishes

This pairs perfectly with a crisp green salad—something with bite, like arugula or romaine, tossed in a bright vinaigrette. The sharpness helps balance the creamy soup. And of course, you can’t go wrong with crusty garlic bread or homemade dinner rolls for dipping. Try a plate of juicy fresh tomatoes or a bowl of marinated olives if you want to keep things really Mediterranean.

Creative Ways to Present

For a dinner party, try serving this in rustic soup mugs set on wooden boards alongside breadsticks for dipping. For family meals, offer a toppings bar with ricotta, chopped parsley, extra Parmesan, and even a pinch of red pepper flakes. If you want something fun for kids, use mini lasagna noodles or broken sheets for easy scooping, and let everyone swirl their own ricotta on top.

Make Ahead and Storage

Storing Leftovers

Let your leftover soup cool to room temperature, then transfer it to airtight containers. It will keep beautifully in the fridge for up to 3 days. The noodles will continue to soak up the broth a bit, making the texture even more comforting the next day—some might say this soup is even better after sitting overnight!

Freezing

If you want to freeze this, consider cooking the noodles separately and adding them fresh when reheating. Still, it’s totally possible to freeze the finished soup—just know that the noodles might soften a bit more upon reheating. Use freezer-safe containers and leave out the ricotta and parsley garnish until you’re ready to serve.

Reheating

Warm your soup gently on the stovetop over medium-low heat, stirring frequently and adding a splash of extra broth or water if it’s gotten a bit thick in the fridge. Microwave reheating works too; just stir every minute to ensure even warming. Top with fresh ricotta and parsley just before serving for the brightest flavor.

FAQs

Can I make this Alfredo Lasagna Soup vegetarian?

Absolutely! Just skip the sausage and use good-quality vegetable broth in place of the chicken broth. You might also want to add some extra veggies like mushrooms, zucchini, or even roasted red peppers for more texture and flavor.

What if I don’t have lasagna noodles?

No worries—any wide, flat pasta will work in a pinch, or even rotini or penne if that’s what you have in the pantry. The rustic charm of the soup is in those jagged noodle pieces, so don’t stress about making it perfect!

Can I lighten up this soup?

If you’d like to make this a bit less rich, swap the heavy cream for half-and-half or milk (though the broth will be thinner), and use reduced-fat ricotta. Skipping or reducing the sausage and Parmesan will also lessen the overall richness.

How do I keep the noodles from getting mushy?

For best results, slightly undercook the noodles so they finish softening as the soup cools. Or, cook and store the noodles separately from the broth, adding them just before serving. This is especially helpful if you’re planning to enjoy leftovers.

Is there a way to add more vegetables?

Definitely! Feel free to stir in sautéed mushrooms, diced bell peppers, zucchini, or kale for more veggie goodness. This recipe is wonderfully flexible—just toss in any extra vegetables you love or have on hand.
