Bake the potatoes and shred the cheese the day before making the soup. If the soup needs to simmer awhile on the stove, you may need to add more chicken broth.
Simple and delicious. It's also vegan if you don't add the cheese at the end. If you prefer a more spicy soup, add a dash or two of hot sauce before serving.
I developed this recipe when I was cooking for large groups of people. It's easy to make and gives you plenty of time to do other things while it's baking.
