Ingredients Notes

The magic of this soup lies in its simple yet flavorful ingredients. Each component contributes to the creamy, hearty texture that makes this dish so special.

Lasagna noodles are the star of the show. Broken into bite-sized pieces, they give the soup that signature lasagna texture without the hassle of layering. You can also swap them for another pasta shape like bowties or rigatoni.

Heavy cream and Parmesan cheese create the rich, velvety Alfredo-style broth. For the best results, use freshly grated Parmesan—it melts better and adds a more intense flavor compared to pre-shredded cheese.

Garlic and onions provide depth and aroma. Sautéing them in butter before adding the broth brings out their sweetness and enhances the overall flavor.

Chicken broth forms the base of the soup. It balances the richness of the Alfredo sauce while adding a savory depth. You can use vegetable broth for a vegetarian version.

Cooked chicken adds protein and heartiness. Rotisserie chicken is an easy shortcut, but you can also cook and shred your own chicken breasts. For a twist, try using Italian sausage for a more robust flavor.

A dash of Italian seasoning and nutmeg ties everything together. Nutmeg may sound unusual, but it subtly enhances the creaminess of the sauce without overpowering the dish.

How To Make This Creamy Alfredo Lasagna Soup

This soup comes together quickly in just a few easy steps. The hardest part is waiting for it to be ready because the aroma is so tempting!

Start by boiling a large pot of salted water and cooking the lasagna noodles until al dente. Drain and set them aside while you prepare the soup base.

In a large pot or Dutch oven, melt butter over medium heat. Add diced onions and minced garlic, sautéing until soft and fragrant. This step builds the foundation of the soup’s rich flavor.

Pour in the chicken broth and bring it to a gentle simmer. Add the shredded cooked chicken and Italian seasoning, letting the flavors meld for a few minutes.

Reduce the heat to low and stir in the heavy cream, grated Parmesan cheese, and a pinch of nutmeg. Stir constantly to prevent the cheese from clumping, creating a smooth, creamy broth.

Add the cooked lasagna noodles and let everything simmer for a few more minutes. The noodles will absorb the delicious flavors, making each bite taste like classic lasagna.

Serve hot, garnished with extra Parmesan, fresh parsley, and a sprinkle of black pepper. For an extra indulgent touch, add a dollop of ricotta cheese on top.

Storage Options

This soup stores well, making it great for leftovers. If you have extra, let it cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 4 days.

For longer storage, freeze the soup without the noodles for up to 3 months. When ready to eat, reheat the soup on the stovetop and add freshly cooked noodles for the best texture.

To reheat, warm the soup over low heat, stirring occasionally. If it has thickened too much, add a splash of broth or cream to loosen it up. Avoid overheating, as the cream can separate.

Variations and Substitutions

This soup is incredibly versatile, and there are plenty of ways to customize it to your taste.

For a meatier version, swap the chicken for crumbled Italian sausage or ground beef. Brown it in the pot before adding the broth for extra flavor.

If you prefer a vegetarian option, skip the chicken and add sautéed mushrooms, spinach, or zucchini. Using vegetable broth instead of chicken broth keeps the dish completely meat-free.

Want a lighter version? Substitute half-and-half or whole milk for the heavy cream. While it won’t be quite as rich, it will still be deliciously creamy.

For a spicier kick, add a pinch of red pepper flakes or a splash of hot sauce. The heat balances the richness of the Alfredo sauce beautifully.

Make it gluten-free by using gluten-free lasagna noodles or your favorite gluten-free pasta. Just be sure to cook them separately and add them at the end to prevent them from becoming mushy.

No matter how you customize it, this Creamy Alfredo Lasagna Soup is sure to become a staple in your comfort food lineup. It’s creamy, cozy, and packed with all the flavors you love in a classic lasagna—without the fuss.
