Sonja's Cheeseburger Soup

This recipe was given to me by my amazing friend Krista.  She says when she shares this recipe with other people they love it...kids too!  Krista makes her soup with ground chicken and chicken broth.  I made the ground beef version.  Everyone in our house gobbled it up! Who knew that adding ketchup and mustard to a soup would be so good! A perfect soup on a cold night.  

1 lb lean ground beef
1 cup chopped onion
1 cup chopped celery
1 cup chopped carrots
2 teaspoons garlic
3 cups beef broth
2 cups diced potatoes
1 teaspoon basil
3 tablespoons butter
1/4 cup flour
1 1/2 cups milk
2 cups shredded cheddar cheese
1/4 cup ketchup
2 tablespoons mustard

1.  Brown together ground beef, onions, celery and carrots until ground beef is cooked and the vegetables are tender.
2.  Stir in beef broth, potatoes and basil.
3.  In a small saucepan melt butter.  Whisk in flour and slowly add milk until thickened. Stir in cheddar cheese, ketchup and mustard. Add to soup.
5.  Serve with a crusty French loaf.  Garnish with chopped pickles.
