This creamy Alfredo Lasagna Soup is a warm hug in a bowl! It features layers of tender pasta, rich Alfredo sauce, and lots of cheesy goodness—all cooked together for a comforting meal.
If you’re like me, you’ll appreciate how easy this is to make. Just throw everything into one pot, and you can enjoy a delicious dinner without all the work of traditional lasagna!
Key Ingredients & Substitutions
Ground Italian Sausage: This adds great flavor. If you want a lighter option, try using ground turkey or chicken. For a vegetarian version, substitute with plant-based sausage or mushrooms.
Onion: A small onion gives depth to the soup. If you’re in a pinch, shallots or even green onions work well. You can also omit it if you’re looking to skip the allium.
Mushrooms: I love using sliced mushrooms for extra texture and flavor. You can swap them for spinach or zucchini, or even leave them out if you’re not a fan.
Alfredo Sauce: Store-bought is easy and tasty, but homemade is even better if you have the time. For a lower-fat option, try a light Alfredo sauce or make a creamy cauliflower sauce.
Cheese: Parmesan is a must for that cheesy richness, but feel free to use Pecorino Romano or nutritional yeast for a vegan twist. Mozzarella adds creaminess but is optional.
How Do You Ensure Perfectly Cooked Noodles in Soup?
Cooking the lasagna noodles directly in the soup makes everything so easy! Just remember a few simple tips:
- Break the lasagna noodles into manageable pieces, so they cook evenly and fit nicely in your bowl.
- Add them to the pot when the broth is bubbling. This helps them cook quickly and absorb all that yummy flavor.
- Keep an eye on them as they cook. Stir occasionally to prevent sticking, and taste a piece to check for doneness around 10-12 minutes.
By cooking them in the soup, they will also thicken the broth a bit, making it even more comforting!

Step-by-Step Instructions:
1. Brown the Sausage:
In a large pot or Dutch oven, heat the olive oil over medium heat. Add the ground Italian sausage and cook until it’s browned. Use a spoon to break it up into small pieces as it cooks. Once done, remove the sausage from the pot and set it aside.
2. Sauté the Vegetables:
In the same pot, add the diced onion and cook until it’s softened, which should take about 3-4 minutes. Next, add the minced garlic and sliced mushrooms. Cook them together until the mushrooms are tender, about 5 minutes.
3. Combine the Bases:
Now return the browned sausage to the pot. Pour in the chicken broth, milk, heavy cream, and the jar of Alfredo sauce. Stir everything nicely until it’s well combined.
4. Season it Up:
Add in the dried Italian seasoning, red pepper flakes (if you like a bit of heat), as well as salt and black pepper to taste. Bring the mixture to a gentle boil, stirring occasionally.
5. Cook the Noodles:
Now it’s time to add the broken pieces of lasagna noodles to the pot. Reduce the heat to medium-low and let it simmer for about 10-12 minutes, stirring occasionally until the noodles are cooked al dente.
6. Add the Cheesy Goodness:
Stir in the grated Parmesan cheese and shredded mozzarella cheese (if using) until they are melted and well combined. This is what makes the soup extra creamy and delicious!
7. Final Touches:
Give the soup a taste and adjust any seasonings if needed. You want it just right!

Can I Use Ground Turkey Instead of Italian Sausage?
Yes, you can absolutely substitute ground turkey for Italian sausage! It will give you a leaner option, but you may want to add some Italian seasoning or herbs to enhance the flavor since turkey is milder.
Can I Make This Soup Vegetarian?
Certainly! To make this soup vegetarian, just skip the sausage and add more vegetables like bell peppers, spinach, or zucchini. You can also use vegetable broth instead of chicken broth for added flavor.
How to Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. When reheating, add a splash of broth or milk to restore the creamy texture since the noodles will absorb some liquid as it sits.
Can I Freeze Alfredo Lasagna Soup?
Yes, you can freeze the soup! Allow it to cool completely and then transfer it to a freezer-safe container. It will keep well for up to 3 months. When ready to eat, thaw in the refrigerator overnight and reheat on the stove, adding some extra liquid if needed.
