How to Make Slow Cooker White Lasagna Soup Recipe
Step 1: Prepare the Slow Cooker Base
Start by tossing diced white onions, minced garlic, Italian seasoning, salt, black pepper, and the optional crushed red pepper flakes into your slow cooker. This flavorful mix forms the aromatic backbone of the soup and sets the stage for all the delicious layers to come.
Step 2: Add Liquids and Chicken
Pour in the chicken stock and give everything a gentle stir to evenly distribute those seasonings. Nestle the chicken breasts on top of the mixture, then scatter the chopped sun-dried tomatoes over the surface. These tomatoes will slowly release their tangy sweetness into the broth as it cooks.
Step 3: Slow Cook to Tender Perfection
Cover and cook this mixture on low for 6 to 8 hours, or on high for 3 to 4 hours. This slow, gentle heat allows the chicken to become fall-apart tender while infusing the broth with deep, savory flavors. The result is a soup base that’s both rich and comforting.
Step 4: Shred the Chicken
Once the chicken is cooked through, remove it from the slow cooker and shred it with two forks. Returning the shredded chicken to the pot ensures every spoonful will have tender, juicy pieces throughout.
Step 5: Thicken and Enrich the Soup
In a separate bowl, whisk together the heavy cream and cornstarch until completely smooth. Pour this creamy mixture into the slow cooker and stir well. This step transforms the broth, making it decadently rich and silky.
Step 6: Final Simmer
Replace the lid and cook on high for an additional 30 minutes. This allows the cream and cornstarch to activate fully, thickening the soup to just the right consistency without losing its comforting broth-like quality.
Step 7: Prepare the Noodles
While the soup finishes cooking, prepare the lasagna noodles according to the package instructions. Once cooked, drain and set them aside, ready to add that perfect pasta texture into your soup bowl.
Step 8: Add Fresh Spinach and Noodles
Stir fresh spinach leaves directly into the hot soup until they wilt beautifully, infusing the dish with both nutrition and vibrant green color. Then fold in the cooked lasagna noodles, gently combining everything for a meal that’s hearty, wholesome, and satisfying.
Step 9: Serve and Enjoy
Ladle the soup into warm bowls and generously sprinkle shredded Parmesan cheese on top along with fresh parsley. Serve hot to experience a comforting taste of Italy with the simplicity and warmth of homemade soup.
How to Serve Slow Cooker White Lasagna Soup Recipe

Garnishes
Shredded Parmesan cheese adds a nutty, salty finish that melts perfectly into the hot soup. Fresh parsley is more than just decoration; its bright, herbaceous notes lighten every bite and add a splash of color that makes the dish feel fresh and inviting.
Side Dishes
This soup shines on its own but pairs wonderfully with warm, crusty bread or garlic breadsticks for dipping. A simple Caesar salad or a crisp side of roasted vegetables adds a lovely contrast in textures and keeps the meal balanced.
Creative Ways to Present
Serve the soup in rustic bowls for a cozy, homey feel or try individual mini slow cookers for a fun dinner party presentation. For a heartier meal, ladle the soup over a bed of extra spinach or chopped kale for even more greens and texture.
Make Ahead and Storage
Storing Leftovers
Leftover Slow Cooker White Lasagna Soup Recipe keeps well in an airtight container in the refrigerator for up to 3 days. The noodles may absorb some broth, so adding a splash of chicken stock when reheating helps bring back that perfect consistency.
Freezing
This soup freezes beautifully, making it an excellent make-ahead meal. Cool completely before transferring to freezer-safe containers. It will last up to 3 months frozen without losing flavor or texture, so you can enjoy homemade comfort anytime.
Reheating
Reheat the soup gently on the stovetop over medium heat, stirring occasionally. Add a bit of chicken stock or water to loosen the soup if it has thickened too much in storage. Avoid overheating to keep the cream from separating and maintain that velvety texture.
FAQs
Can I use ground chicken or turkey instead of chicken breasts?
Definitely! Ground chicken or turkey can be used for a quicker cooking time and slightly different texture. Just brown it before adding to the slow cooker for best results.
Is it possible to make this soup vegetarian?
Yes, you can substitute vegetable broth for chicken stock and omit the chicken altogether. Add extra sun-dried tomatoes, mushrooms, or white beans to keep the soup hearty and satisfying.
Can I prepare everything the night before?
You sure can! Just combine all the ingredients except the noodles, cream, and spinach in the slow cooker insert and refrigerate overnight. In the morning, start the slow cooker and continue with the recipe when ready.
What kind of lasagna noodles work best?
Traditional wide lasagna noodles broken into pieces work best for authenticity, but you can use any pasta shape you have on hand — just mind the cooking time so they don’t get mushy.
How spicy is the soup with the crushed red pepper flakes?
The red pepper flakes add a subtle warmth but nothing overwhelming. You can adjust the amount or leave them out entirely depending on your heat preference.
