How to Make One Pot White Chicken Lasagna Soup Recipe

Step 1: Sauté the Veggies

Start by melting butter with olive oil in a large, heavy-bottomed pot over medium heat. Add the peeled and sliced carrots, diced onion, red bell pepper, and shredded zucchini. Sauté these veggies for about 5-7 minutes until they become tender and aromatic. This builds the flavor base for your soup and gently softens the vegetables, ensuring every bite has a little bit of freshness and texture.

Step 2: Add Garlic and Flour

Next, stir in the minced garlic and cook for another minute until fragrant. Sprinkle the all-purpose flour over the vegetables and garlic, stirring constantly to coat everything evenly. This step helps thicken the soup later, so don’t skip it. Let the flour cook for about 2 minutes to remove any raw taste, forming a roux-like base.

Step 3: Build the Broth

Slowly pour in 6 cups of the chicken broth, whisking to avoid lumps. Add the cornstarch, chicken bouillon, and bay leaves along with all the dried herbs and seasonings: parsley, basil, oregano, thyme, salt, pepper, and red pepper flakes if you’re using them. Stir well and bring the mixture to a simmer. This is where the magic happens as the broth thickens slightly and flavors meld beautifully.

Step 4: Add Chicken and Noodles

Once the broth is gently simmering, stir in the cooked chopped chicken and broken lasagna noodles. Use the remaining 3 cups of chicken broth to ensure there’s enough liquid for the noodles to cook through without sticking. Let this gently cook for about 10-12 minutes, stirring occasionally, until the noodles are tender but not mushy and the chicken is fully heated through.

Step 5: Finish with Cream and Spinach

Reduce heat to low and stir in the half and half and optional heavy cream for an extra creamy texture. Then fold in the thawed and drained spinach, allowing it to blend into the soup and add vibrant color. Finally, mix in most of the Parmesan cheese, reserving some for garnish. Let the soup warm through but avoid boiling to keep the cream from curdling. Your soup is now perfectly creamy and cheesy—just like a comforting bowl of lasagna in every spoonful.

Garnishes

For a delicious finishing touch, sprinkle shredded mozzarella on top and let it melt slightly—this creates a gooey, cheesy layer that makes the soup feel extra special. You can also add a fresh sprinkling of extra Parmesan or a pinch of chopped parsley to brighten things up visually and flavor-wise. A crack of fresh black pepper is a nice touch as well.

Side Dishes

This soup is quite hearty on its own, but if you'd like to amp up the meal, light sides like a crisp green salad with a tangy vinaigrette or some crunchy garlic bread pair beautifully. The salad offers a refreshing contrast while garlic bread is perfect for dipping and soaking up every last drop of that creamy broth.

Creative Ways to Present

For a more playful presentation, serve the soup in mini bread bowls or hollowed-out Parmesan rounds to impress guests and add edible charm. You can also layer the soup with a sprinkle of mozzarella and broil briefly to create a bubbly, golden topping, echoing classic lasagna flavors in a new way. For family dinners, ladle soup into wide mugs for comforting, easy serving.

Make Ahead and Storage

Storing Leftovers

Leftover soup keeps wonderfully in an airtight container in the refrigerator for up to 3 days. Because it contains dairy and noodles, storing properly and reheating carefully are key to preserving texture and flavor.

Freezing

Freezing the soup is possible but with some precautions. It’s best to freeze without the half and half or cream, as dairy can separate when frozen. Freeze in portion-sized containers and add fresh dairy when reheating. Also, the noodles may soften more after freezing, so consider slightly undercooking noodles initially if you plan to freeze.

Reheating

Reheat gently on the stove over low heat, stirring frequently. Add a splash of broth or half and half to revitalize the soup’s creamy texture if it seems too thick. Avoid boiling once cream is added to prevent curdling. Microwave reheating is convenient but warm in short intervals with stirring in between to maintain consistency.

FAQs

Can I use fresh chicken instead of cooked chicken?

Absolutely! If using raw chicken, cook it fully in the pot before adding the veggies, or cook separately and then add it in at step 4. Using cooked chicken like rotisserie makes the process quicker and easier.

Is there a vegetarian version of this soup?

Yes! You can swap chicken broth with vegetable broth and omit the chicken, or replace it with hearty mushrooms or tofu for a tasty vegetarian variation that still feels hearty and satisfying.

Can I substitute lasagna noodles with another type of pasta?

Definitely! Short pasta like penne, rigatoni, or broken spaghetti work well and cook in about the same time. Just keep an eye on the pasta so it doesn’t overcook.

What if I don’t have half and half or heavy cream?

You can use whole milk, but the soup won’t be as rich and creamy. For more creaminess, try stirring in some cream cheese or a small handful of shredded cheese while finishing the soup.

How spicy is the soup with red pepper flakes?

The red pepper flakes add just a gentle kick that complements the flavors without overwhelming them. If you prefer no heat, simply leave them out; the soup is delicious either way.
