Creamy Alfredo Lasagna Soup combines all the best parts of lasagna with the warming comfort of a creamy soup. Packed with sausage, mushrooms, tender spinach, and bouncy pasta, each spoonful feels like a hug on a cold night. This is my favorite solution when I crave lasagna but want something cozy and quick without all the fuss.
I whipped this up on a snowy weekday when lasagna felt impossible—ever since, even my picky eater has asked for it on repeat. It is the kind of meal that turns a chilly evening into something special.
Ingredients
- Ground sausage: brings richness and spice to every bite Choose one with Italian seasoning for the best depth
- Small onion: adds sweetness and aromatic base Look for onions with papery skins and no soft spots
- Mushrooms: create hearty texture and earthy flavor Opt for firm white or cremini mushrooms for best results
- Garlic: infuses warm depth Use fresh cloves not jarred for boldest impact
- Fresh baby spinach: wilts perfectly into the broth Choose leaves that are vibrant and crisp
- Low sodium chicken broth: forms a savory foundation Go for high quality broth without too many additives
- Lasagna noodles: give that classic lasagna feel Snap regular noodles into rough pieces for the right texture
- Dried oregano and basil: lift everything with Italian herb notes Check your spices for freshness so they do not taste dull
- Butter: adds richness and rounds out the sauce Look for creamy unsalted
- Flour: creates that thick velvety soup base Choose unbleached flour if possible
- Milk: makes the soup extra creamy Use whole milk for best mouthfeel
- Grated parmesan: finishes the soup with sharp nutty flavor Pick a real block to grate fresh for melting and ultimate flavor
Step-by-Step Instructions
- Brown the Sausage:
- Start by cooking the ground sausage in a large saucepan over medium heat Stir frequently to break it up and cook until no pink remains This gives the soup a savory flavor base
- Build the Flavor Base:
- Add chopped onion and sliced mushrooms to the sausage Lower the heat to medium low and cook for five to six minutes until onions become soft and mushrooms release their juices This step is essential for layering in that sweet earthy background
- Wilt the Spinach and Add Garlic:
- Add minced garlic and spinach Stir everything together and cook for one minute The spinach will wilt down quickly and the garlic will become fragrant but not bitter
- Simmer with Chicken Broth:
- Pour in the low sodium chicken broth and bring to a gentle simmer Let it cook for about five minutes so all the flavors start mingling
- Add Noodles and Herbs:
- Break lasagna noodles into smaller pieces and add them to the pot Sprinkle in dried oregano and basil Raise the heat and bring to a low boil Stir often so the noodles do not stick together Cook for ten to twelve minutes until the noodles are just tender
- Make the Creamy Alfredo Base:
- While the noodles cook melt butter in a separate skillet over medium low heat Whisk in the flour and cook for one minute stirring constantly until bubbling Gently whisk in milk and keep stirring until the mixture is thick and smooth This step creates the classic Alfredo texture
- Melt in the Parmesan:
- Turn off the heat and slowly whisk in grated Parmesan cheese Keep mixing until the cheese melts and the sauce is very creamy If needed place the pan over the lowest heat and whisk constantly to fully melt the Parmesan
- Combine and Finish the Soup:
- Slowly whisk the creamy Parmesan mixture into the soup pot Stir gently to blend everything and warm the soup through Adjust salt and pepper if needed Serve immediately for the creamiest texture

Lasagna soup always reminds me of Sunday afternoons when my whole family gathers in the kitchen Everyone wants to help break up the noodles and sneak extra cheese into the pot Parmesan truly makes this soup extraordinary with its nutty depth
