Step-by-Step Cooking Instructions

Creating the perfect creamy Alfredo lasagna soup is easy when you follow these simple steps:

1. Sauté the Garlic & Make a Roux

In a large pot or Dutch oven, melt butter over medium heat. Once melted, add minced garlic and cook until fragrant—about 30 seconds. Stir constantly to prevent burning.

Next, whisk in flour and cook for another minute. This step creates a roux, which thickens the broth and gives it a smooth, creamy consistency. Be sure to stir well to avoid lumps.

2. Add the Broth & Simmer

Slowly pour in chicken broth, whisking continuously to blend it with the roux. Bring to a gentle simmer and allow it to cook for about 5 minutes.

Now, stir in Italian seasoning, salt, and pepper. These spices enhance the overall flavor of the soup, giving it a deep, herbaceous aroma.

3. Cook the Lasagna Noodles

Break the lasagna noodles into bite-sized pieces and add them to the pot. Stir occasionally to prevent sticking. Simmer until the noodles are fully cooked, about 10-12 minutes.

Alternative Option: If you prefer a firmer texture, cook the noodles separately in salted water and add them to the soup at the end.

4. Add the Chicken & Cheese

Once the noodles are tender, stir in the shredded chicken. Lower the heat and slowly add heavy cream, followed by Parmesan cheese. Stir gently until the cheese melts into the broth, creating a rich and creamy texture.

For extra cheesiness, sprinkle mozzarella cheese on top, cover the pot, and let it sit for 1-2 minutes to allow the cheese to melt.

5. Serve & Enjoy

Ladle the soup into bowls and garnish with fresh parsley, extra Parmesan, or a drizzle of olive oil. Pair with a side of garlic bread or a simple side salad for a complete meal.

Pro Tips for the Creamiest Alfredo Lasagna Soup

Want to take your creamy Alfredo lasagna soup to the next level? Here are some expert tips:

✔ Use Freshly Grated Cheese – Pre-packaged shredded cheese contains anti-caking agents that prevent smooth melting. Always use fresh Parmesan for the best texture.
✔ Let It Rest Before Serving – Allowing the soup to sit for a few minutes before serving thickens it naturally.
✔ Add More Butter for Silkiness – Stir in an extra tablespoon of butter at the end for an ultra-rich, velvety texture.
✔ Adjust Consistency as Needed – If the soup is too thick, add a splash of warm chicken broth or milk until it reaches your desired consistency.

How to Thicken Lasagna Soup

If your soup turns out thinner than expected, try these thickening techniques:

✔ Flour or Cornstarch Slurry – Mix 1 tbsp of cornstarch with 2 tbsp of water and stir it into the soup. Simmer for a few minutes until it thickens.
✔ More Cheese – Parmesan and mozzarella naturally thicken the broth when melted. Add extra cheese gradually until you reach the right consistency.
✔ Simmer Without a Lid – Allowing the soup to cook uncovered for an extra 5 minutes helps evaporate excess liquid, making the broth thicker.

Can You Freeze Chicken Alfredo Lasagna Soup?

Yes! This soup freezes well, but keep in mind a few key points to maintain its creamy texture:

✔ Cool Completely – Let the soup cool to room temperature before storing.
✔ Use Freezer-Safe Containers – Store in an airtight container, leaving some space at the top to allow for expansion.
✔ Reheat Slowly – Warm on low heat, stirring frequently. If the soup separates, whisk in a little heavy cream or broth to restore creaminess.

Storage Tip: The soup stays fresh for 3-4 days in the refrigerator and up to 3 months in the freezer.

Pro Tips for the Perfect Creamy Alfredo Lasagna Soup

While this creamy Alfredo lasagna soup is already delicious, a few expert tricks can take it to the next level. Whether you’re aiming for a thicker consistency, deeper flavor, or a richer texture, these tips will help you create a truly unforgettable dish.

1. Choose High-Quality Dairy Products

Since Alfredo sauce relies on dairy for its creamy texture, using high-quality ingredients makes a significant difference.

✔ Heavy cream vs. milk: Always opt for heavy cream instead of milk for a richer, silkier consistency. If you prefer a lighter version, half-and-half can work, but the soup may be thinner.
✔ Freshly grated Parmesan: Pre-packaged grated cheese contains anti-caking agents that prevent smooth melting. Always use freshly grated Parmesan for a velvety finish.
✔ Butter matters: For the best flavor, choose unsalted butter so you can control the salt level in your soup.

2. Simmer, Don’t Boil

Boiling dairy-based soups can cause the sauce to split or curdle. Instead, keep the heat at a gentle simmer and stir frequently to prevent separation.

Pro Tip: If your soup starts to curdle, whisk in a small amount of cold heavy cream or a teaspoon of cornstarch slurry to stabilize it.

3. Adjust the Thickness to Your Liking

If you prefer a thicker soup, try these methods:

✔ Use a flour or cornstarch slurry: Mix 1 tablespoon of flour or cornstarch with 2 tablespoons of cold water and whisk it into the soup. Simmer until thickened.
✔ Add more cheese: Extra Parmesan or mozzarella naturally thickens the broth.
✔ Reduce the broth: Let the soup simmer uncovered for an additional 5-10 minutes to evaporate excess liquid.

If your soup becomes too thick, add a splash of warm chicken broth or milk to loosen it up.

How to Store and Reheat Alfredo Lasagna Soup

Can you freeze chicken Alfredo lasagna soup? Absolutely! However, because this soup contains dairy, a few adjustments will ensure it reheats perfectly.

1. Storing in the Refrigerator

✔ Allow the soup to cool completely before transferring it to an airtight container.
✔ Store in the fridge for 3-4 days.
✔ When reheating, use low heat and stir frequently to maintain the creamy texture.

2. Freezing for Longer Storage

✔ Leave out the noodles if freezing. They tend to absorb too much liquid and become mushy.
✔ Use freezer-safe bags or airtight containers, leaving some space at the top for expansion.
✔ Freeze for up to 3 months.

Pro Tip: Label your container with the date to track freshness.

3. Reheating for the Best Texture

✔ Thaw frozen soup overnight in the fridge before reheating.
✔ Warm slowly over low heat, stirring continuously.
✔ If the soup looks too thick, add a splash of broth or milk to restore creaminess.

For the best texture, cook fresh noodles separately and add them right before serving.
