That is exactly why this Crockpot White Lasagna Soup has become a weekly staple in our home.

It ticks absolutely every single box you could possibly want for a weeknight dinner. It is unbelievably creamy, deeply cozy, hearty enough to satisfy the biggest appetites, and packed with wholesome ingredients. Best of all? It is a slow cooker recipe, which means the appliance does all the heavy lifting for you while you go about your day. You get all the comforting, rich, cheesy flavors of a traditional white chicken lasagna, but without any of the tedious layering, boiling, or baking.

What Is Crockpot White Lasagna Soup?

Imagine taking everything you adore about a classic, decadent white chicken lasagna and transforming it into a warm, slurpable, comforting bowl of soup. That is exactly what we are doing here. Crockpot White Lasagna Soup is a brilliant, deconstructed version of the beloved Italian-American pasta dish, designed specifically for your slow cooker.

It starts with a beautifully savory base of chicken broth infused with garlic, Italian herbs, and a pinch of crushed red pepper flakes. Boneless, skinless chicken breasts and tangy sun-dried tomatoes simmer low and slow in this broth until the meat is melt-in-your-mouth tender. Towards the end of the cooking time, we stir in a velvety mixture of heavy cream and Parmesan cheese to thicken the broth into a rich sauce. Finally, we fold in fresh baby spinach and perfectly cooked, broken lasagna noodles. When you serve it up, you top each bowl with a generous scoop of ricotta cheese that melts into the hot broth. It is literally a hug in a bowl.

How to Make Crockpot White Lasagna Soup

Quick Overview

Making this soup is wonderfully straightforward. You will start by adding your seasonings, broth, chicken, and sun-dried tomatoes to the slow cooker to simmer until the chicken is tender and ready to shred. Once shredded, you will thicken the soup with a quick slurry of heavy cream and cornstarch, letting it cook on high for just a bit longer to get that perfect velvety texture. Finally, you will stir in fresh spinach, a generous handful of Parmesan, and your pre-cooked lasagna noodles. Top it with ricotta, and dinner is served!

Ingredients

Here is what you will need to grab from the pantry and fridge to bring this cozy meal to life:

• Chicken breasts: Boneless and skinless work best so they shred effortlessly after slow cooking.
• Chicken broth: The savory foundation of our soup. I recommend low-sodium so you can control the saltiness.
• Garlic & Spices: Fresh garlic, Italian seasoning, onion powder, salt, black pepper, and a pinch of crushed red pepper flakes for a gentle, warming kick.
• Sun-dried tomatoes: These are my secret weapon! They add a tangy, sweet depth that cuts through the rich cream perfectly.
• Heavy cream & Cornstarch: Whisked together, these create that luxurious, thick, silky white sauce texture.
• Baby spinach: For a beautiful pop of green color and fresh flavor.
• Lasagna noodles: Broken into bite-sized pieces. We cook these separately so they stay perfectly al dente.
• Cheeses: Grated Parmesan for the broth, and creamy ricotta for that classic lasagna topping.
• Fresh parsley: A bright, fresh garnish to finish the bowl.

Step-by-Step Instructions

Step 1: Build the Flavor Base

Start by adding your minced garlic, Italian seasoning, salt, black pepper, onion powder, and crushed red pepper flakes right into the bottom of your slow cooker. Pour in the chicken broth and give it a good stir to wake up all those spices. Nestle your chicken breasts directly into the seasoned broth, and scatter the chopped sun-dried tomatoes right over the top. Cover your crockpot and let it cook on LOW for 6 to 7 hours, or on HIGH for 3 to 4 hours. You will know it is ready when the chicken is incredibly tender.

Step 2: Shred the Chicken

Once the cooking time is up, carefully remove the chicken breasts from the slow cooker and place them on a cutting board. Grab two forks and gently pull the meat apart until it is fully shredded. Return all that juicy, shredded chicken right back into the hot broth.

Step 3: Thicken the Broth

In a small separate bowl, whisk together your heavy cream and cornstarch until the mixture is completely smooth and free of any lumps. Pour this creamy slurry into the slow cooker, stirring well to combine. Put the lid back on, turn the heat up to HIGH, and let it bubble away for another 20 to 30 minutes. This step is crucial—it turns the thin broth into a rich, velvety soup.

Step 4: Add the Finishing Touches

While the soup is thickening, boil your broken lasagna noodles in a separate pot on the stove until they are al dente, then drain them. Remove the lid from your slow cooker and stir in the fresh baby spinach, watching it wilt beautifully into the hot liquid. Gently fold in your cooked noodles and the grated Parmesan cheese. Give it a gentle mix to coat everything. Ladle the hot soup into bowls, and top each serving with extra Parmesan, fresh parsley, and a big, comforting scoop of ricotta cheese.

What to Serve It With

Because this Crockpot White Lasagna Soup is so rich and hearty, it honestly stands perfectly well on its own as a complete meal. However, if you want to stretch the dinner or just add a little something extra to the table, you cannot go wrong with some classic Italian sides.

I highly recommend serving this with a warm, crusty baguette or homemade garlic knots. You are going to want something sturdy to soak up every last drop of that creamy, cheesy broth at the bottom of your bowl! If you want to balance out the richness of the cream and cheese, a simple, crisp green side salad tossed in a light, zesty lemon vinaigrette is the perfect pairing. Sometimes, I even like to make quick crostini by toasting sliced bread and brushing it with a little garlic butter.

Top Tips for Perfecting Your Crockpot White Lasagna Soup

Over the years of making this recipe, I have learned a few tricks that take this soup from good to absolutely spectacular. First and foremost: always cook your noodles separately! It might be tempting to just toss dry pasta into the slow cooker to save a pot, but trust me on this. Lasagna noodles release a ton of starch and absorb a massive amount of liquid. If you cook them in the crockpot, you will end up with a mushy pasta casserole instead of a soup. Cooking them on the stove keeps that perfect, chewy bite.

If you are short on time in the morning, use the ultimate shortcut: rotisserie chicken. You can completely skip the long slow-cooking step. Just add the broth, spices, tomatoes, and shredded rotisserie chicken to the pot, heat it through, and move straight to the cream and cornstarch step.

Finally, always taste your soup right before serving. Both the Parmesan cheese and the chicken broth add varying levels of salt depending on the brands you use. Give the broth a quick taste test and add a pinch more salt or pepper if you feel it needs a little boost.

Storing and Reheating Tips

If you are lucky enough to have leftovers, this soup stores wonderfully! Allow the soup to cool completely to room temperature before transferring it to an airtight container. It will stay fresh and delicious in the refrigerator for up to 4 days.

When you are ready to reheat, you can pop individual portions into the microwave for a minute or two, stirring halfway through. If you are reheating a larger batch, gently warm it on the stovetop over medium-low heat. Keep in mind that the lasagna noodles will continue to soak up the broth as they sit in the fridge overnight. If your soup looks a little too thick the next day, simply splash in a little extra chicken broth or a dash of milk while reheating to loosen it right back up to that perfect soup consistency.
