Chicken Alfredo Soup

Chicken Alfredo Soup, an easy one-pot soup with fettuccine, chicken, spinach, and an alfredo and broth base. The best hearty soup for chilly winter nights!

This Chicken Alfredo Soup is perfect for chilly nights! It’s delicious comfort food at its best. A kind of a cross between Fettuccine Alfredo and Chicken Noodle Soup. Rich and creamy, this soup is a family pleaser for sure.

My Homemade Alfredo Sauce was a bit of the inspiration behind this soup. Since we all could eat that Alfredo Sauce with a spoon seemed only natural to turn it into a soup.

You should be able to easily find all these ingredients. Be sure to break the fettuccine into small bite-size pieces before cooking.

This is a great recipe to use up any leftover chicken (or substitute sausage, shrimp, or your favorite protein). Or see my How to Make Shredded Chicken if you’d like some easy options.

Chicken Alfredo Soup Ingredients

• Chicken broth
• Onion
• Garlic
• Fettuccine (or your favorite pasta)
• Heavy cream
• Butter
• Chicken (precooked)
• Baby spinach
• Parmesan cheese, good quality freshly grated
• Salt/Pepper to taste

It’s going to seem like a lot of chicken broth, but the pasta and other ingredients will soak some of it in. If you want you could also do half broth and half water.

How to Make Chicken Alfredo Soup

1. PREP BROTH. Add chicken broth, onion, and garlic to a large pot over medium-high heat. Cover and bring to a boil.
2. COOK PASTA. Remove pot lid, and stir in fettuccine pieces. Cook about 10 minutes or until pasta is almost al dente and just slightly undercooked (it will continue to cook slightly as you add other ingredients).
3. COMBINE. Stir in heavy cream and butter to pot while still over medium-high heat. Cook about a minute or until slightly thickened. Stir in chicken, baby spinach, and parmesan cheese. Cook another 2-3 minutes or until combined and heated through and spinach has wilted. Add salt/pepper to taste.

Serving Suggestions

• Serve hot in soup bowls. You can store leftovers and reheat as well.
• Some crackers or even croutons would be great in the soup.
• You could also serve with bread on the side such as a roll (like these Homemade Dinner Rolls or Garlic Cheddar Drop Biscuits) or piece of baguette.
• Some fresh chopped parsley or even chopped cooked bacon on top of the soup would also be delicious.

Quick Tips for Best Results

• Break the fettuccine pasta into small pieces but don’t worry if they’re not all the exact same size.
• The pasta will continue to cook as you add other ingredients so don’t worry if it’s slightly undercooked before you add other things.
• The soup isn’t overly thick, but if you’re looking for more thickness, try whisking in a little cornstarch mixed with water at the end of the cooking to thicken a little more.
• Use fresh baby spinach or chopped regular spinach. It will shrink down in the soup and only take a little while to cook.
• This is a great recipe to use leftover precooked chicken you have in the fridge. If you don’t have any around check out this How To Make Shredded Chicken for some ideas or this Instant Pot Shredded Chicken.
