This white lasagna soup is exactly that, and I’m so excited to share it with you. It has all the rich, creamy, and cheesy goodness of traditional lasagna, but it comes together in one pot with so much less fuss.

I promise, this recipe is designed for busy weeknights when you need something delicious without the stress. It’s packed with tender chicken, savory sun-dried tomatoes, and perfectly cooked pasta, all swimming in a velvety, herb-infused broth. If you’re looking for a new go-to comfort food, you’ve found it. Let’s get cooking!

Why You’ll Love This Foolproof White Lasagna Soup

I know there are a lot of lasagna soup recipes out there, but I truly believe this one will become a favorite in your home. I designed it to be as simple and rewarding as possible.

It’s a one-pot wonder, which means fewer dishes and less cleanup for you. Everything from sautéing the onions to simmering the chicken happens right in the same pot, building layers of incredible flavor with minimal effort. It’s the perfect solution for a busy weeknight.

This soup is also incredibly creamy without being heavy. The secret is a simple mixture of half-and-half and cornstarch, which creates a silky texture that feels so luxurious. You get all the comfort of a cream-based soup without any complicated steps.

Best of all, it delivers that classic lasagna flavor you love without the layering and baking. It’s a cozy, satisfying meal that feels special enough for a Sunday dinner but is easy enough for a Tuesday night. It truly is a cozy bear hug in a bowl.

Essential Kitchen Tools for Your White Lasagna Soup Success

You don’t need a lot of fancy equipment for this recipe, which is part of its charm. Having the right tools, however, can make the process even smoother. I find these items make a world of difference.

A good Dutch oven or a large soup pot is my top recommendation. Its heavy bottom distributes heat evenly, which is perfect for sautéing the onions without burning them and for simmering the soup gently.

For shredding the chicken, you can absolutely use two forks, but meat shredding claws make the job so much faster and easier. They’re one of those little kitchen gadgets I didn’t know I needed until I tried them.

And if you want to adapt this recipe, having a reliable slow cooker or Instant Pot on hand will open up even more convenient cooking options for those extra-busy days.

Ingredients for the Best Creamy White Lasagna Soup

Here are the simple, flavorful ingredients you’ll need to create this comforting soup. I’ve found this combination gives the absolute best results.

• 2 tablespoons unsalted butter: I use unsalted butter to control the saltiness of the final dish, and it adds a rich base for our aromatics.
• 1 medium onion ( finely chopped): This builds the first layer of savory flavor. Chopping it finely helps it melt into the soup.
• 3 cloves garlic (finely minced): Garlic adds that essential aromatic punch that makes the soup so fragrant and delicious.
• 2 teaspoons Italian seasoning: This is my go-to shortcut for that classic lasagna herb flavor without measuring out multiple spices.
• 1 teaspoon salt: For seasoning the soup from the start. You can always add more later.
• ¼ teaspoon pepper: Adds a little bit of warmth and spice.
• ⅛ teaspoon red chili flakes: This is optional, but I love the subtle background heat it provides.
• 3 cups low-sodium chicken broth: Using low-sodium broth lets you control the final salt level and ensures the soup’s flavor shines.
• 2 boneless skinless chicken breasts (about 1 lb): The chicken cooks right in the broth, making it incredibly tender and easy to shred.
• ¼ cup sun-dried tomatoes (chopped): These little gems add a sweet, tangy, and wonderfully chewy element to the soup.
• 2 cups dry, short pasta or broken lasagna noodles: Use whatever short pasta you love. Broken lasagna noodles give it that classic feel.
• 1 cup half-and-half: This creates the creamy base of the soup without being too heavy.
• 2 tablespoons cornstarch: My secret weapon for thickening the soup perfectly without any lumps.
• 1 cup fresh spinach (roughly chopped): The spinach wilts right into the soup at the end, adding a pop of color and nutrients.
• Ricotta cheese, Parmesan cheese, and shredded mozzarella cheese for garnish: The finishing touch! This trio of cheeses melts beautifully and gives you that authentic lasagna experience.

How to Make White Lasagna Soup on the Stovetop

This stovetop method is straightforward and perfect for building layers of flavor. Just follow these simple steps, and you’ll have a delicious pot of soup in no time.

1. Melt the butter in a large Dutch oven or soup pot over medium heat.
2. Add the onion and cook, stirring, until just starting to brown, about 3 to 4 minutes.
3. Stir in the garlic, Italian seasoning, salt, pepper, and chili flakes. Cook for 1 minute until fragrant.
4. Stir in the broth. Add the uncooked chicken and sun-dried tomatoes.
5. Increase the heat to medium-high and bring to a simmer. Cover and reduce the heat to medium-low and cook for 12 to 15 minutes, until the chicken is cooked through. A meat thermometer inserted into the chicken should reach 165°F (74°C).
6. Meanwhile, in a large pot of boiling, salted water, cook the pasta according to the package directions.
7. Remove the chicken from the soup and shred with two forks.
8. In a small bowl, whisk together the half-and-half and cornstarch until smooth. Stir this slurry into the soup and cook for 1 to 2 minutes, until it has slightly thickened.
   

   Pro Tip: Whisking the cornstarch and cold half-and-half together before adding it to the hot soup is the key to preventing lumps. This creates a smooth “slurry” that incorporates seamlessly for a perfectly silky texture.

9. Stir the shredded chicken, cooked pasta, and spinach into the pot and heat through until the spinach has wilted.
10. Taste and adjust seasonings if you’d like. Serve hot with generous spoonfuls of ricotta, Parmesan, and mozzarella cheese.

Alternative Cooking Methods for Your White Lasagna Soup

I know we all have different kitchen setups and schedules. The great news is this soup is incredibly adaptable! Here’s how you can make it in your slow cooker or Instant Pot.

White Lasagna Soup in the Slow Cooker

1. Melt butter in a skillet over medium heat and cook the onion until softened. Add the garlic, Italian seasoning, salt, pepper, and chili flakes, and cook for one more minute. Transfer this mixture to your slow cooker.
2. Add the chicken broth, sun-dried tomatoes, and raw chicken breasts to the slow cooker.
3. Cover and cook on LOW for 4 to 6 hours or on HIGH for 2 to 3 hours, until the chicken is cooked through.
4. Remove the chicken and shred it. Cook your pasta separately according to package directions.
5. In a small bowl, whisk together the half-and-half and cornstarch. Stir this into the slow cooker.
6. Add the shredded chicken, cooked pasta, and spinach to the slow cooker. Stir everything together and cook on HIGH for another 15 minutes, or until the soup has thickened and the spinach is wilted.
7. Serve hot with your favorite cheese toppings.

White Lasagna Soup in the Instant Pot

1. Set your Instant Pot to the SAUTÉ function. Melt the butter, then add the onion and cook until softened. Stir in the garlic, Italian seasoning, salt, pepper, and chili flakes, cooking for another minute.
2. Pour in the chicken broth, scraping up any browned bits from the bottom of the pot.
3. Add the sun-dried tomatoes and place the raw chicken breasts into the liquid.
4. Secure the lid, set the valve to SEALING, and cook on HIGH PRESSURE for 10 minutes.
5. While the chicken cooks, cook your pasta separately on the stovetop according to package directions.
6. Once the pressure cooking is complete, let the pressure release naturally for 5 minutes, then perform a quick release for the remaining pressure.
7. Carefully remove the chicken and shred it. Set the Instant Pot back to SAUTÉ.
8. Whisk the half-and-half and cornstarch together, then stir it into the soup. Cook for a few minutes until it thickens slightly.
9. Stir in the shredded chicken, cooked pasta, and fresh spinach. Let it heat through until the spinach wilts. Serve immediately with cheese.

White Lasagna Soup Variations, Substitutions & Customization

One of the things I love most about this soup is how easy it is to customize. Feel free to play around with the ingredients to make it your own!

Make it Dairy-Free or Vegan

To make this soup dairy-free, use a dairy-free butter substitute and replace the half-and-half with full-fat coconut milk or a cashew cream. For the cheese topping, use your favorite dairy-free ricotta, parmesan, and mozzarella alternatives. To make it fully vegan, swap the chicken for a can of cannellini beans or chickpeas and use vegetable broth.

Low-Carb Options

If you’re watching your carbs, you can easily substitute the pasta. Zucchini ribbons (zoodles) or spaghetti squash are excellent choices. I recommend adding them at the very end of cooking, as they only need a minute or two to soften. Shirataki noodles are another great option.

Tips for Picky Eaters

For families with picky eaters, this soup is a winner. If your kids aren’t fans of spinach, you can chop it very finely or even blend it into the broth before adding the other ingredients. I also love setting up a topping bar with different cheeses, some croutons, and fresh herbs so everyone can customize their own bowl.

Pro Tips for the Creamiest White Lasagna Soup

After making this soup many, many times, I’ve picked up a few tricks that guarantee it turns out perfectly creamy and flavorful every single time.

Flavor Building 101: Aromatics & Herbs

Don’t rush the first step! Sautéing the onion until it’s soft and just starting to brown builds a sweet, savory foundation. When you add the garlic and Italian seasoning, let them cook for just a minute until you can smell them. This “blooming” process wakes up the spices and makes their flavor so much more vibrant in the finished soup.

Adjusting Seasoning

I always recommend tasting the soup at the very end, right before you serve it. The saltiness can change as the broth simmers and reduces. Give it a final taste and add another pinch of salt, pepper, or even a squeeze of lemon juice if you think it needs a little brightness.

Achieving the Perfect Consistency

If your soup seems too thin, you can let it simmer for a few extra minutes to reduce. You can also make another small slurry with 1 teaspoon of cornstarch and a tablespoon of cold water and stir that in. If it’s too thick, simply stir in a splash of chicken broth until it reaches the consistency you like.

Preventing Mushy Noodles

The best way to avoid mushy noodles, especially if you plan on having leftovers, is to cook the pasta separately. This gives you complete control. When serving, you can either stir the cooked pasta into the main pot or place a scoop of pasta into each individual bowl and ladle the hot soup over it.

Meal Prep & Storage Guide for White Lasagna Soup

This soup is fantastic for meal prep and leftovers. A little planning goes a long way in making your week easier.

Make-Ahead Steps

To get a head start, you can chop your onion and mince the garlic a day or two in advance and store them in an airtight container in the fridge. You can also cook and shred the chicken ahead of time. With these components ready to go, the soup comes together in a flash.

Storing Leftovers

Store leftover soup in an airtight container in the refrigerator for up to 3 days. For the best texture, I highly recommend storing the cooked pasta separately from the soup base. This prevents the noodles from soaking up all the liquid and becoming soft overnight. When you’re ready to eat, just combine and reheat.

Freezing White Lasagna Soup

You can absolutely freeze this soup, but I advise doing so without the pasta and dairy. Cream-based soups can sometimes separate when thawed. Freeze the soup base (after the chicken is cooked and shredded but before adding the half-and-half and spinach) in a freezer-safe container for up to 3 months. When you’re ready to serve, thaw it in the refrigerator, reheat it on the stovetop, and then stir in the half-and-half, fresh spinach, and freshly cooked pasta.

Serving Suggestions for Your Cozy White Lasagna Soup

This soup is a hearty meal all on its own, but a few simple sides can make it feel even more special. I love serving it with a loaf of warm, crusty bread or some garlic bread for dipping into that creamy broth. It’s the best way to make sure you don’t miss a single drop.

A simple green salad with a light vinaigrette is also a perfect companion. The fresh, crisp greens provide a wonderful contrast to the rich, creamy soup. It’s a simple and balanced meal that I turn to again and again.

Frequently Asked Questions about White Lasagna Soup

Can I use rotisserie chicken?
Yes, absolutely! A store-bought rotisserie chicken is a fantastic time-saver. Simply shred about 2 to 3 cups of meat and stir it into the soup at the end with the spinach and cooked pasta.

What type of chicken is best (breast vs. thigh)?
I wrote the recipe with boneless, skinless chicken breasts because they cook quickly and shred beautifully. However, boneless, skinless chicken thighs would also be delicious. They contain a bit more fat, which can add extra flavor and moisture to the soup.

Are there specific brands of broth or cheese you recommend?
I don’t have a specific brand I’m loyal to, but I always recommend using a low-sodium chicken broth to control the salt. For the cheeses, using fresh, good-quality ricotta, Parmesan, and mozzarella will make a big difference in the final taste and texture.

What if my dairy curdles?
This can sometimes happen if the soup is too hot when you add the dairy. The best way to prevent it is to temper the half-and-half. After making the cornstarch slurry, slowly whisk a ladleful of the hot broth into the slurry. Then, pour that tempered mixture back into the soup pot while stirring constantly. This gently raises the temperature of the dairy and helps it incorporate smoothly.
