The recipe yield is:
Combine all ingredients for soup stock, simmer 5 to 6 hours then strain. Discard bones and vegetables. To make soup, saute onions sliced 1/4 inch thick in hot butter until softened. Pour in stock and simmer gently, covered, for 1 hour. To thicken soup, blend butter and flour into paste. Stir into soup and continue simmering until thickened, about minutes. Season with salt and pepper. Spoon soup into individual bowls, top each with toasted bread. Sprinkle with cheese and bake in a 350F oven until cheese has melted, about 5 to 10 minutes.
