Ingredients You’ll Need

Makes ~6 servings | Prep: 15 min | Cook: 35–40 min | Total: approx. 55 min

• 2 tbsp unsalted butter

• 2 tbsp olive oil

• 1 lb boneless skinless chicken thighs or breasts, diced small (optional—skip for vegetarian version)

• 1 medium onion, finely chopped

• 3 cloves garlic, minced

• ¼ cup all-purpose flour

• 3 cups milk (whole or 2%)

• 2 cups low-sodium chicken or vegetable broth

• ½ cup heavy cream or half-and-half

• 1 cup grated Parmesan cheese (plus extra for garnish)

• 1 cup shredded mozzarella cheese

• 6 oz broken lasagna noodles (regular or gluten-free)

• Salt & freshly ground pepper, to taste

• 1 cup fresh spinach or baby kale (optional)

• Chopped fresh parsley, for garnish

Step-By-Step Instructions

Sauté the Chicken & Aromatics

Heat butter together with olive oil in a large soup pot over medium heat. Add the diced chicken, season lightly with salt and pepper, and cook until lightly golden, about 5 minutes. Remove from pot and set aside. In the same pot, add onion and sauté until softened, about 4 minutes. Stir in the garlic and cook for another 30 seconds until fragrant.

Build the Alfredo Base

Sprinkle the flour over the onions, stirring constantly for 1 minute to create a roux. Slowly whisk in the milk and broth, ensuring no lumps form. Continue whisking until the mixture thickens slightly, about 3–4 minutes. Stir in the heavy cream or half-and-half, then add the cheeses—Parmesan and mozzarella—until melted and the soupbase is silky and creamy.

Simmer Pasta & Reincorporate Chicken

Return the cooked chicken to the pot. Add lasagna noodles and simmer for about 10 minutes, stirring occasionally, until noodles are al dente and soup has a luscious creamy body.

Add Greens & Final Seasoning

If using, stir in fresh spinach or baby kale and let it wilt slowly (2–3 minutes). Taste and season with additional salt or pepper as needed.

Serve & Garnish

Ladle the warm, creamy soup into bowls. Sprinkle with extra Parmesan and chopped parsley for a fresh, bright finish.

Pro Tips & Variations

• Vegetarian Variation: Omit chicken, sauté extra mushrooms or zucchini for veggie heft.

• Gluten-Free Option: Use GF flour for roux and gluten-free pasta noodles.

• Lower-Fat Version: Swap heavy cream for additional milk and reduce cheeses slightly.

• Extra Flavor Touch: Add a pinch of nutmeg into the Alfredo base—or stir in a spoonful of pesto before serving.

• Extra Cheesy Pull: Top with shredded mozzarella and broil briefly in oven-safe bowls for that melty cheese crust.
