  • 1 Tablespoon flour
  • 1 quart organic beef broth
  • 1/4 cup coffee optional
  • 3 cups of shredded Swiss Cheese
  • 1/4 cup crispy onions

Instructions

  • melt the butter in a heavy duty pot about 2 quarts in size
  • slice off the tops and bottoms of the onion, cut in half and then in slices
  • add to the butter stir to cover, reduce heat, and cook for 45 minutes, stirring every 15 minutes or so
  • while the onions are caramelizing slice the entire loaf of bread into 1-2 inch cubes and set aside
  • after 30 minutes add the sliced celery and cook for the last 15 minutes with the onions
  • after 45 minutes add flour and cook for five minutes
  • preheat the oven to 350 degrees
  • stir in the beef broth and the coffee, if using, and cook for 10 minutes on medium
  • pour the soup into a 9X13 baking dish
  • top with all the bread chunks press down into the soup to make them all fit
  • cover with the shredded Swiss cheese and the crispy onions
  • bake for 15 minutes or until the top is crispy and browned
  • serve on plates or in bowls, it's thicker than soup, really a casserole with gooey bread and cheesy topside
