I found a bland recipe and made it my own!
2 onions, thinly sliced
1/4 c. butter
2 tbsp all-purpose flour
32 oz beef broth
1/4 c. white wine
2 tbsp worchestershire sauce
1 tsp parsley
1 tsp herbs de province
French bread, toasted
Preheat oven to 425 degrees F(220 degrees C). Separate sliced onion into single rings.
In a medium sauce pan saute onions in butter until soft, approximately 20 minutes. Stir in flour and gradually add broth, wine, worchestershire sauce, parsley and herbs. Bring to a boil and simmer for 20 minutes.
Meanwhile, toast French bread slices.
Place toasted bread into soup bowls. Pour soup mixture over bread and top with swiss cheese. Bake until cheese is melted.
