This creamy white lasagna soup turns all the cozy, cheesy flavors you love in classic lasagna into a warm bowl perfect for weeknights. It feels indulgent without the fuss of layering noodles in a casserole.
I first made this on a chilly evening when I wanted lasagna but no oven time. It instantly became one of our favorite sit-down suppers on busy nights.
Ingredients
- Italian sausage: brings a savory meaty base. Choose high-quality sausage for the best flavor
- Onion and garlic: build an aromatic foundation, use fresh and firm garlic cloves
- Chicken broth: keeps the broth flavorful yet light. Homemade or low sodium works best here
- White beans: thicken the soup and add a creamy texture without heaviness. Use canned for convenience
- Heavy cream: adds richness that mimics a traditional white sauce without complicated steps
- Spinach: offers a pop of color and freshness. Go for vibrant green leaves without any wilting
- Ricotta cheese: gives the soup that signature creamy, tangy character of white lasagna
- Mozzarella: melts perfectly for stringy, luscious bites
- Parmesan cheese: adds sharpness and depth. Opt for fresh grated rather than pre-packaged
- Lasagna noodles: broken into bite-sized pieces so no awkward slurping and easy spooning
- Salt and pepper: to taste for seasoning and brightness
Instructions
- Build The Sausage Base:
- Cook the Italian sausage in a large pot over medium heat until it is nicely browned, breaking it apart with a spoon for even cooking. This step infuses the soup with deep, savory notes. Remove the sausage and set aside to use later.
- Sauté Aromatics:
- In the same pot, add chopped onion and minced garlic. Cook over medium heat until softened and fragrant, about three minutes. This layer brings complexity to the flavor without overpowering.
- Combine Broth and Beans:
- Pour in chicken broth and drained white beans. Bring to a boil, then lower to a simmer. The beans will start to break down and lightly thicken the broth.
- Stir In Creamy Ingredients:
- Add heavy cream, chopped spinach, ricotta, mozzarella, and Parmesan cheeses. Stir gently to meld all these creamy elements. Let the soup gently simmer for about five minutes so the cheese melts and the spinach wilts.
- Cook The Noodles:
- Add the broken lasagna noodles directly into the pot and cook until tender, around ten minutes. Stir occasionally to prevent sticking and ensure even cooking.
- Return Sausage and Final Seasoning:
- Add the browned sausage back to the pot and cook for another five minutes to marry the flavors. Taste and season with salt and freshly ground pepper as needed.
- Serve Hot:
- Ladle into bowls and finish with a sprinkle of grated Parmesan on top. It is best enjoyed warm so the cheese stays wonderfully gooey.

This dish reminds me of family meals where everyone gathers around and savors the comfort of familiar flavors.
Storage tips
Store leftover soup in airtight containers in the refrigerator for up to three days. When reheating, add a splash of broth or water to loosen the soup as it tends to thicken in the fridge.
Ingredient swaps
For a vegetarian version, replace Italian sausage with plant-based sausage or add extra white beans. Swap chicken broth for vegetable broth to keep it meatless without sacrificing flavor. Use part skim ricotta and reduced fat cheeses to lighten up while keeping creaminess.
Serving ideas
Serve with crusty bread or garlic knots to sop up the hearty broth. A simple green salad on the side balances the richness well. Garnishing with fresh herbs like basil or parsley adds a fresh pop that brightens every bite.

This soup combines indulgence and comfort in every bowl, perfect for busy nights when you want a homemade feel without the fuss.
