Creamy White Lasagna Soup
Creamy White Lasagna Soup is a cozy, cheesy twist on the classic comfort food! Made with flavorful Italian sausage, fresh spinach, tender noodles, and plenty of cheese – this hearty one-pot meal is perfect for chilly nights!
The Best Lasagna Soup
Lasagna and lasagna soup are like delicious cousins — same comforting flavors, totally different personalities! Traditional lasagna brings all the drama with its beautiful layers of pasta, rich sauce, and gooey cheese baked to golden perfection.
Lasagna soup, on the other hand, is its fun, low-maintenance twin — all the flavor of classic lasagna, but easier to whip up on a weeknight. You still get the noodles, the creamy cheese, and that irresistible Italian seasoning, just in a cozy bowl you can eat with a spoon.
Lasagna soup is the best of both worlds: comfort food made simple, and every bit as satisfying! In addition to this delicious soup, we’ve also got our Turkey Lasagna Soup made with red sauce.

Why This Recipe Works:
- One-pot convenience – All the flavors come together in a single pot, making this lasagna soup quick and easy.
- Savory depth – Italian sausage and a parmesan rind add rich, layered flavors.
- Creamy richness – A roux with whole milk and parmesan cheese create a velvety, indulgent broth.
- Customizable – Easy to adjust for more spice, extra veggies, or different proteins.
What You’ll Need:
- Italian sausage
- onion and garlic
- seasonings – kosher salt, freshly ground black pepper, Italian seasoning, and red pepper flakes
- all-purpose flour
- lower-sodium chicken broth
- whole milk
- parmesan rind – optional ingredient
- lasagna noodles
- parmesan cheese
- spinach leaves
Recipe Substitutions:
- Instead of Italian sausage, use ground beef, ground turkey, or even chicken.
- Use another type of pasta like penne, rigatoni, or broken spaghetti, instead of lasagna noodles.
- While we use whole milk, any other dairy works fine. Try half and half or heavy cream.
- Kale is a good substitute for spinach leaves.
- Try using another seasoning blend instead of Italian seasoning and red pepper flakes.
- Vegetable or beef broth could be used as a substitute for chicken broth.
NOTE: If you want a thicker soup, simply add more meat and/or pasta!
How to make Creamy White Lasagna Soup:
Step 1
Cook sausage and onion. Heat a stock pot over medium-high heat. Add sausage and onion and cook until sausage is browned and cooked through.
Step 2
Add garlic, seasonings, and flour. Add minced garlic and stir for 30 seconds. Then add the seasonings and flour and stir constantly for two minutes so that the flour absorbs into the grease.
Step 3
Add broth and milk. Then add the chicken broth and whole milk and stir well. Increase heat to get soup to a boil and then reduce slightly, stirring frequently.
Step 4
Add lasagna noodles. Add the lasagna noodles and stir. Let cook until pasta is al dente.
Step 5
Finish with spinach and parmesan cheese. Then add the fresh spinach and parmesan cheese and stir for another minute. Remove pot from heat.
Step 6
Serve soup. Serve white lasagna soup with extra parmesan cheese and shredded mozzarella cheese.
We like to serve this delicious soup with some fresh bread for dipping. Try our Chewy French Bread, Italian Herb Bread, or Garlic Sourdough Bread.
Storing and Freezing:
- Store leftover lasagna soup in an airtight container in your refrigerator for 3-4 days.
- Freeze soup in a freezer bag and lay flat in your freezer. Soup will freeze well for up to three months.
Recipe FAQs:
Yes! Lean sausage works, though you may want to add a bit of butter or olive oil to build the roux. You can also skip the sausage for a vegetarian version and add extra vegetables or beans.
You could boil the noodles separately, but we prefer to cook everything in one pot.
Yes, you can make it a day in advance and store in the fridge. The flavors will deepen overnight. Add extra milk or broth when reheating if it thickens too much.
This soup has a gentle kick from red pepper flakes, but you can adjust the heat up or down to suit your taste.
