If you love white lasagna but don’t love the time it takes to make it, this White Lasagna Soup is about to become a favorite. It’s creamy, cozy, packed with chicken and vegetables, and comes together in one pot — and using rotisserie chicken makes it perfect for an easy weeknight dinner.

This soup gets its creamy texture from full-fat (unsweetened) coconut milk instead of heavy cream, which keeps the broth rich and smooth without feeling heavy.

While it simmers, the aroma of garlic, herbs, and creamy broth fills the kitchen… and don’t be surprised if everyone suddenly starts asking when dinner will be ready.

TidyMom tip: Rotisserie chicken is one of my favorite shortcuts for soups…. it saves time and adds so much flavor.

Let’s make some soup — this one comes together easier than you’d think.

Why Use Coconut Milk in This Soup?

Full-fat unsweetened coconut milk makes this soup creamy without needing heavy cream or half-and-half. It blends smoothly into the broth, helps keep melted cheese silky, and gives the soup a rich texture without feeling overly heavy.

Another nice bonus is that the soup base is naturally dairy-free, which can be helpful for anyone avoiding dairy — but more importantly, it simply makes a really delicious, creamy soup.

And don’t worry, it doesn’t taste like coconut. Once everything cooks together, the flavor is savory and similar to a creamy white lasagna sauce.

If you don’t have coconut milk, heavy cream, half-and-half, or evaporated milk will all work. Just keep the heat gentle when adding dairy so it stays smooth.

TidyMom tip: Coconut milk is one of those pantry ingredients that quietly makes soups taste like you worked a lot harder than you did.

FAQs

Can I make this soup ahead of time?

Yes. It reheats well and makes great leftovers.

Does the soup taste like coconut?

No. Coconut milk adds creaminess, not coconut flavor. Once everything cooks together, the flavor is rich and savory.

Can I use a different type of milk?

Full-fat coconut milk gives the best texture, but heavy cream, half-and-half, or evaporated milk can work if heated gently.

Can I freeze this soup?

Yes, though noodles may soften slightly. For best texture, you can freeze the soup without noodles and add fresh pasta when reheating.

Could I add more vegetables to the soup?

Yes. Try using zucchini, peas, cauliflower rice, or even extra spinach for a healthier option. All of these work well and won’t overpower the soup.

What should I serve with this soup?

Crusty bread, garlic toast, or a simple side salad pair perfectly to make it a complete meal.

White Lasagna Soup with Chicken

Yield: 8 servings
Prep Time: 10 minutes
Cook Time: 25 minutes
Total Time: 35 minutes

Creamy White Lasagna Soup with chicken, spinach, and tender noodles. An easy one-pot dinner that’s cozy, comforting, and perfect for weeknights.

Ingredients

  • 1 tablespoon olive oil
  • 1 medium yellow onion, diced
  • 3 cloves garlic, minced
  • 1 cup sliced baby bell mushrooms
  • 2 medium carrots, diced
  • 2 ribs of celery, diced
  • 3 cups chopped spinach
  • 3 cups rotisserie chicken
  • 8 cups low-sodium chicken broth
  • 1 teaspoon Italian seasoning
  • ½ teaspoon dried basil
  • ½ teaspoon garlic powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 9 lasagna noodles, broken into pieces
  • 14 ounce can unsweetened full-fat coconut milk
  • 2 tablespoons cornstarch
  • 1 cup shredded mozzarella

Instructions

  1. Heat the olive oil in a large pot over medium heat. Add in the onions, carrots, and celery. Cook for 5-7 minutes or until softened. Add garlic and sauté 30 seconds more.
  2. Pour in the chicken broth. Add shredded chicken, Italian seasoning, basil, garlic powder, salt, and pepper. Bring to a gentle simmer.
  3. Add uncooked pasta and mushrooms to the pot. Cook for 10-12 minutes, stirring occasionally.
  4. Add in the spinach and cook until wilted.
  5. In a separate bowl, whisk together the coconut milk and cornstarch. Pour into the soup, reduce the heat, and let it gently simmer for 5-7 minutes or until slightly thickened.
  6. Stir in mozzarella cheese and parmesan cheese until melted and creamy. If the soup becomes too thick, you can add a splash more of chicken broth.
  7. Ladle into bowls and top with fresh herbs and an extra sprinkle of parmesan cheese if desired.

Notes

• Full-fat unsweetened coconut milk gives the creamiest texture. Light coconut milk won’t thicken the soup as well.

• Stir the pasta occasionally while it cooks to keep the noodles from sticking together.

• Keep the heat low when adding the cheese so it melts smoothly and doesn’t separate.

• This soup thickens slightly as it sits because the noodles absorb broth. When reheating, stir in a splash of chicken broth if needed.

• Broken lasagna noodles or bow tie pasta both work well in this soup.
