Use a whole chicken! Cooking a whole chicken (or buying one that Costco roasted for you) can be more economical than buying chicken pieces. You can use the carcass to make homemade stock. You'll only need a small amount of chicken meat for the soup itself, meaning you can are basically using the leftovers to make this soup. You can easily make this homemade cream of chicken soup with turkey when the whole birds go on sale in the fall. Just call it cream of turkey. ;)
