Cozy White Lasagna Soup for a Comforting One-Pot Meal

Enjoy all the flavors of classic lasagna in a creamy, hearty soup.

There's nothing like a warm, comforting bowl of soup on a chilly day and this white lasagna soup delivers all the creamy, cheesy goodness of traditional lasagna without the fuss. With tender lasagna noodles, earthy mushrooms, and a rich, herb-infused broth, this one-pot meal is perfect for a cozy night in.

Why You’ll Love This White Lasagna Soup

Not only is this soup incredibly comforting, but it’s also:

  • Quick and Easy: Ready in under 30 minutes, with minimal prep.

  • One-Pot Wonder: Fewer dishes to wash, making it a practical choice for busy weeknights.

  • Flavor-Packed: A blend of Italian seasoning, fresh thyme, and pesto adds depth to every bite.

Ingredients

  • 1/4 cup olive oil

  • 16 ounces sliced mixed mushrooms

  • 1 tablespoon fresh thyme leaves

  • 1 teaspoon kosher salt

  • 2 teaspoons Italian seasoning

  • 3 cloves garlic, minced

  • 1/4 cup all-purpose flour

  • 6 cups low-sodium vegetable broth

  • 1 cup heavy cream

  • 8 ounces no-boil lasagna noodles, broken into 2-inch pieces

  • 4 cups baby spinach (one 5-ounce container)

  • Ricotta cheese, for serving

  • Pesto sauce, for serving

Directions

  1. Sauté the Mushrooms:
    Heat olive oil in a large Dutch oven over medium-high heat. Add the mushrooms, thyme, and salt. Cook, stirring occasionally, until the mushrooms release their liquid and turn golden brown, about 6 to 8 minutes.

  2. Add Aromatics and Flour:
    Stir in the Italian seasoning and minced garlic, cooking until fragrant, about 1 minute. Sprinkle in the flour, mixing well to coat the mushrooms evenly.

  3. Build the Broth:
    Gradually add the vegetable broth, stirring as you go. Bring the mixture to a gentle simmer and cook until slightly thickened, approximately 10 minutes.

  4. Incorporate the Cream and Noodles:
    Pour in the heavy cream and return the soup to a simmer. Add the lasagna noodles and cook until they are tender, 3 to 4 minutes.

  5. Finish with Spinach:
    Stir in the baby spinach and cook just until wilted, about 1 minute. Turn off the heat.

  6. Serve:
    Ladle the soup into bowls and top with dollops of ricotta cheese and drizzles of pesto sauce.

Tips for the Perfect Soup:

  • Mushroom Mix: Use a blend of cremini, shiitake, and white mushrooms for a richer flavor.

  • Extra Creaminess: Add a handful of shredded mozzarella or Parmesan just before serving.

  • Protein Boost: Stir in cooked chicken or white beans to make it even heartier.

Nutritional Perks

Mushrooms are a fantastic source of antioxidants and B vitamins, while spinach adds a dose of iron and vitamin K. Using a vegetable broth keeps this dish vegetarian-friendly, and swapping heavy cream with half-and-half can lighten it up without sacrificing the creamy texture.
