Cheeseburger Soup

When I first heard about this soup I had my doubts!  Cheeseburger soup with ketchup and mustard?  What?  But I have to say, it's actually delicious!  It's crazy how it really does taste similar to a cheeseburger!  It's a hearty soup with a yummy flavor!  You have to try it!

1 lb hamburger
1 cup onion, diced
3/4 cup celery, diced
3/4 cup carrots, diced
1 garlic clove, minced
3 cups chicken broth
2 cups potatoes, peeled, diced
1 teaspoon basil
3 tablespoons butter
1/4 cup featherlight flour
1 1/2 cups milk
2 cups Cheddar cheese, grated
1/4 cup ketchup
2 tablespoons mustard
salt & pepper to taste

Brown hamburger, onion, celery, carrots and garlic.  Season with a little salt & pepper.  Stir in broth, potatoes and basil.  Bring to a boil; reduce heat and simmer 10 - 12 minutes or until potatoes are cooked through.  In a separate saucepan melt butter.  Whisk in flour and heat through.  Add the milk and stir until smooth. Add the milk mixture to the soup and bring to a boil.  Reduce heat to a simmer.  Add cheese, ketchup, and mustard, stirring until the cheese is melted.  Add salt and pepper to taste.  You can serve this with chopped pickles, or relish!

Note:  I just make my chicken broth with water and 3 chicken bouillon cubes.
