Ingredients:
4 tablespoons butter
1 lb onions, peeled and finely sliced
salt and pepper
1/2 teaspoon ground mustard
2 teaspoons flour
4 cups beef stock
1 cup white wine
French bread, sliced and lightly toasted
swiss cheese, sliced or shredded
parmesan cheese, fresh grated
Directions:
In a big saucepan, melt the butter; add the onions, salt and pepper, and mustard.
Saute over low heat, stirring occasionally, until onions are browned (20-30 minutes).
Add the flour and stir until smooth.
Add the stock and wine; stir constantly until mixture comes to a boil.
Lower the heat and simmer, covered, for 30 minutes.
Note: can be made in the crock-pot and cooked on LOW all day after the ingredients are browned.
To serve: place French bread slices in oven-proof bowls, add cheeses over the bread.
Pour soup over the bread and place bowls under the broiler until the cheese melts.
Note: I put the bowls on a baking sheet then place them in the oven under the broiler.
