How to Make White Lasagna Soup Recipe

Step 1: Build Your Flavor Base

Start by tossing the diced onion, minced garlic, Italian seasoning, salt, black pepper, and crushed red pepper flakes into your slow cooker. This combination creates the aromatic foundation your soup needs, mixing savory depth with a little herbal flair. Pour the chicken stock over everything and stir, letting those flavors mingle before the protein enters the party.

Step 2: Add the Chicken and Sundried Tomatoes

Place the boneless skinless chicken breasts right on top of the flavorful broth, then sprinkle the chopped sundried tomatoes evenly over the surface. The tomatoes add a slightly sweet and tangy note that balances the creaminess that’s coming later. Cover and set your slow cooker to low for 6-8 hours or high for 3-4 hours — whichever fits your schedule. The chicken will cook slowly, becoming tender and juicy while infusing the broth with rich flavor.

Step 3: Shred the Chicken

Once your chicken is perfectly cooked, take it out and shred it with two forks — this is one of those satisfying steps that feels like a labor of love. Return the shredded chicken back to the slow cooker to soak up even more deliciousness.

Step 4: Thicken with Cream and Cornstarch

Whisk together the heavy cream and cornstarch until smooth. This mixture is your secret weapon for creating that creamy, thick broth without any clumps. Pour it into the slow cooker and stir well to combine. Cover and cook on high for another 30 minutes to allow it to thicken up beautifully while the flavors meld.

Step 5: Prepare the Lasagna Noodles and Spinach

While the soup finishes cooking, boil the lasagna noodles according to the package directions until al dente, then drain and set aside. When the cream mixture is ready, stir in the fresh spinach directly into the hot soup—it will wilt quickly, adding a fresh, green pop that’s just as pleasing to the eye as it is to your palate.

Step 6: Final Assembly and Serve

Just before serving, gently fold the cooked lasagna noodles into the slow cooker, making sure they’re evenly distributed but not mushy. Ladle the soup into bowls, then top with a generous handful of shredded Parmesan cheese and a sprinkle of fresh parsley for that perfect finishing touch.

Garnishes

A sprinkle of shredded Parmesan cheese and fresh parsley is essential to elevate this White Lasagna Soup Recipe from cozy comfort to a restaurant-worthy meal. The cheese adds a salty richness that perfectly complements the creamy broth, while parsley freshens each spoonful with vibrant color and brightness.

Side Dishes

This soup is pretty much a complete meal, but it pairs beautifully with a crisp green salad dressed in lemon vinaigrette or crusty garlic bread. Both sides add a textural contrast and brightness that keep the meal balanced and exciting.

Creative Ways to Present

Want to impress your dinner guests or make weeknight family dinners more fun? Serve the soup in mini bread bowls or colorful mismatched bowls for a cozy, inviting vibe. You can also sprinkle toasted pine nuts or a drizzle of pesto on top for an unexpected layer of nuttiness and herbal freshness.

Make Ahead and Storage

Storing Leftovers

This White Lasagna Soup Recipe keeps beautifully in the refrigerator for up to 3 days. Store it in an airtight container to preserve the creamy texture and vibrant flavors. The noodles might absorb some broth over time, so it’s best to keep cooked noodles separate if possible for longer freshness.

Freezing

You can freeze the soup without the cooked noodles for up to 2 months. Leave the noodles out when freezing and add freshly cooked ones when you reheat. This keeps the texture perfect without any sogginess that sometimes happens with freezing pasta.

Reheating

Reheat on the stovetop over medium-low heat, stirring gently and adding a splash of chicken stock or cream if the soup has thickened too much. Add the cooked lasagna noodles at the last moment to warm through without getting mushy, and finish with fresh Parmesan and parsley.

FAQs

Can I make this White Lasagna Soup Recipe without a slow cooker?

Absolutely! You can simmer the ingredients on the stovetop in a large pot. Start by sautéing the onions and garlic, then add the stock, chicken, and spices. Cook on low heat, covered, for about 1 to 1.5 hours until the chicken is tender, then continue with the remaining steps.

What can I substitute for heavy cream?

If you want a lighter option, you can use half-and-half or whole milk, but the soup will be less creamy and rich. To maintain thickness, increase the cornstarch slightly. Coconut cream can also work for a dairy-free twist, but it will add subtle coconut flavor.

Can I use a different type of pasta?

Yes! While broken lasagna noodles are traditional here for that layered taste, small pasta shapes like shells, penne, or rigatoni can also work wonderfully. Just be sure to cook them separately and add just before serving to avoid sogginess.

Is this soup spicy?

The recipe includes crushed red pepper flakes as optional, so you control the heat level. Without them, the soup is mild, creamy, and perfect for all ages. Add the flakes if you like a gentle kick for a little extra warmth.

Can I prepare this recipe for meal prep?

Definitely! This White Lasagna Soup Recipe is fantastic for meal prep because you can make a big batch and portion it out for several days. Keep the noodles separate until serving, and reheat gently to enjoy that fresh, homemade feel all week long.
