About the Ingredients
Olive Oil
Used for sautéing to brown the meat and enhance the flavor of the aromatics.
Ground Italian Sausage or Alternatives
Italian sausage adds bold, savory depth; beef, turkey, or plant-based options work well too.
Onion
Finely chopped to build sweetness and aroma as it softens.
Garlic
Fresh garlic boosts savoriness and pairs perfectly with Alfredo; garlic powder works as a substitute.
Chicken or Vegetable Broth
Adds body and deepens flavor; vegetable broth keeps it vegetarian with plant-based sausage.
Water
Lightens the broth just enough to cook the noodles while maintaining creaminess.
Alfredo Sauce
Creates the rich, velvety base of the soup; jarred or homemade both work.
Lasagna Noodles
Broken pieces mimic classic lasagna; rigatoni or penne can be used instead.
Dried Basil and Oregano
Add comforting Italian herb flavor and balance the richness.
Crushed Red Pepper
Brings subtle heat that can be adjusted to taste.
Mozzarella and Parmesan Cheese
Mozzarella melts for creaminess; Parmesan adds sharp, savory depth.
Ricotta Cheese
Dolloped on top to melt into the soup for a classic lasagna finish.
Fresh Parsley
Adds color and freshness to brighten the creamy dish.
Tips & Tricks
Use a heavy-bottomed pot
This prevents the noodles from sticking as they simmer, ensuring an even cook.
Break the lasagna noodles
Breaking the noodles into pieces ensures they cook evenly and mimic the texture of a lasagna.
Stir frequently
Stirring the pot frequently while simmering helps prevent the pasta from clumping together.
Pro Tips
- Use whole-milk ricotta for the richest flavor.
- For a thicker soup, simmer a few additional minutes; for a thinner soup, add more broth.
- If using plant-based meat, reduce oil when sautéing, as these products release less fat.
Step-by-Step Instructions
Sauté the Sausage
Heat oil in a large pot over medium heat. Add sausage and cook for 5–7 minutes, breaking it apart until browned.
Add Aromatics
Add onion and cook for 3–4 minutes until soft. Stir in garlic and cook for 1 more minute.
Combine the Broth
Pour in broth and water, stirring to combine well.
Incorporate Alfredo Sauce
Add Alfredo sauce and mix thoroughly to create a creamy base.
Add the Noodles
Bring to a gentle boil and add broken lasagna noodles, stirring to distribute evenly.
Season the Soup
Stir in basil, oregano, and crushed red pepper for added depth and flavor.
Simmer the Soup
Simmer uncovered for 8–10 minutes, stirring occasionally, until noodles are al dente.
Add the Cheeses
Add mozzarella and Parmesan, stirring until melted and creamy.
Finish with Ricotta
Spoon ricotta on top and allow it to warm slightly without mixing.
Serve and Garnish
Ladle into bowls and garnish with parsley and extra Parmesan if desired.

How to Store Creamy Alfredo Lasagna Soup
Refrigerator
Refrigerate leftovers in an airtight container for up to 4 days.
Freezer
Freeze without the noodles for up to 2 months. Add fresh pasta when reheating for the best texture.
Room Temperature
Not recommended for storage at room temperature due to dairy content.
Reheating
The soup thickens as it sits; add a splash of broth or water when reheating. Reheat gently on the stovetop or in the microwave.
Frequently Asked Questions
Can I make this recipe ahead of time?
Yes, but the pasta will continue to absorb liquid. Make the base ahead and cook the noodles separately for best results.

Absolutely. Homemade sauce will enhance the soup’s flavor and creaminess.
Can I make this soup dairy-free?
Use dairy-free Alfredo and substitute plant-based mozzarella, Parmesan, and ricotta.
Can I add vegetables?
Yes. Spinach, mushrooms, or zucchini make excellent additions.
How do I keep the noodles from getting too soft?
Simmer them only until al dente, and avoid overcooking during reheating.
