Baked Onion Soup

A fairly quick and easy homemade onion soup ladled over slices of toasted French bread, then topped with sliced Swiss cheese and baked just to melt the cheese.

Recipe Ingredients:

4 tablespoons butter or margarine
6 cups sliced peeled onions
2 tablespoons all-purpose flour
6 cups beef broth
2 tablespoons white wine vinegar
1/2 teaspoon salt
1/2 teaspoon ground black pepper
1/2 pound French bread, sliced and toasted
6 ounces Swiss cheese, sliced
1/2 cup freshly grated Parmesan cheese

Cooking Directions:

1. Preheat oven to 375°F (190°C).
2. Melt butter in a heavy stockpot; sauté onions over medium-low heat until light brown, stirring occasionally, 8 to 10 minutes.
3. Sprinkle flour over onions. Stir in beef broth, vinegar, salt and pepper. Bring to a boil, reduce the heat, and simmer uncovered for 10 minutes.
4. Place toasted slices of French bread in oven-safe serving bowls. Ladle soup over bread and place a slice of Swiss cheese on top of each bowl. Sprinkle with Parmesan cheese.
5. Bake until cheese has melted, about 5 minutes. Serve hot.
