Easy Chicken Alfredo Soup Recipe

• This soup is made in one pot with simple ingredients like rotisserie chicken to save tons of prep time!
• It’s rich, creamy, and loaded with tender pasta, broccoli, and plenty of Parmesan flavor. Just like chicken alfredo, but in soup form!

Ingredients for Chicken Alfredo Soup

• Butter: Creates the flavorful base of the soup and helps sauté the onion. I typically use salted, but unsalted works as well.
• Yellow Onion: Adds savory depth to the broth. White onion works well, too.
• Garlic: Brings classic alfredo flavor. Fresh garlic is best, but jarred garlic will work in a pinch.
• Herbs & Spices: Italian seasoning, garlic powder, onion powder, and nutmeg come together to add tons of flavor to this chicken alfredo soup recipe. You can also use other dried herbs – dried thyme, dried oregano, dried rosemary – instead, and omit the nutmeg if you don’t have any on hand.
• Flour: Thickens the soup slightly so it’s creamy without being heavy. Stick with all-purpose flour for this recipe.
• Chicken Stock: Forms the base of the soup. Chicken broth or veggie broth both work instead.
• Half and Half: Adds creaminess without being too rich. Heavy cream can be used for a richer soup, or whole milk for a lighter version.
• Short Pasta: Soaks up the creamy broth and makes the soup hearty. Rotini, penne, or trotolle work best.
• Broccoli Florets: Adds color, texture, and a fresh bite. Cauliflower or frozen peas can be substituted.
• Parmesan Cheese: Gives the soup its classic alfredo flavor. Freshly grated cheese melts best and offers the best flavor.
• Rotisserie Chicken: Makes this recipe quick and easy. Any cooked leftover chicken works.
• Balsamic Vinegar: A small splash balances the richness of the soup and boosts the flavors of all the ingredients. White balsamic vinegar, red wine vinegar, white wine vinegar, or even apple cider vinegar will work instead. Don’t skip the acid!

How to Make Chicken Alfredo Soup

Heat butter in a large pot or Dutch oven over medium heat. Add onion and a couple pinches of salt and pepper, and cook for about 4 minutes, stirring frequently. Add garlic, Italian seasoning, garlic powder, onion powder, and nutmeg, and cook for about 1 minute, stirring frequently. Add flour and cook for another minute, stirring frequently, to remove the raw flour taste.

Add a few splashes of chicken stock to deglaze the pot, scraping all the flavorful bits off the bottom.

Stir in the remaining chicken stock, half and half, pasta, and broccoli, along with a couple pinches of salt and pepper. Bring to a simmer over medium-high heat.

Reduce heat to low and simmer gently for 4–5 minutes, stirring occasionally, until the pasta is al dente and the broccoli is tender. Remove from heat and stir in Parmesan cheese until melted and smooth.

Stir in shredded chicken and balsamic vinegar.

Season to taste with salt and pepper and serve with extra Parmesan on top.

Things to Know

• Cut the broccoli into uniform-sized pieces about an inch or smaller so that they cook through fully and are done at the same time as the pasta.
• Stir often once the pasta is added so it doesn’t stick to the bottom of the pot.
• Grate Parmesan fresh for the smoothest, creamiest texture.
• If the soup thickens too much, add a splash of chicken stock or milk to loosen it up.

Make-Ahead Instructions

• This soup tastes best when it’s fresh because the noodles continue to soak up the broth as it sits.
• If you’re planning to make this soup ahead of time and enjoy it throughout the week, I recommend cooking it fully, but without the pasta. Then cook the pasta separately until al dente.
• When you reheat the soup, add the pasta to the soup and cook until it’s warmed through.

Storing Leftovers

• Store leftover soup in an airtight container in the refrigerator for up to 2 days.
• The pasta will continue to absorb liquid as it sits, but it will stay good for at least a day or two.

Reheating Chicken Alfredo Soup

• Reheat gently on the stovetop over medium-low heat, stirring often.
• Add a splash of chicken stock or milk to loosen it up.
• Season to taste with salt and pepper before serving.
