french onion soup

Last minute I decided to make a soup to compliment my main dish for our dinner swap tonight. I needed a soup with ingredients I had on hand so chose this very simple, tasty soup.

french onion soup (slightly adapted from allrecipes.com)
1/4 cup butter
2 pounds onions, thinly sliced
1/2 tablespoon sugar
4 tablespoons all-purpose flour
3 (14.5 ounce) cans beef broth
2 cups water
1 teaspoon salt
1 teaspoon dried minced onion
1 teaspoon beef bouillon granules
1/4 teaspoon garlic salt
1/4 teaspoon pepper (I used McCormick Smokehouse ground black pepper)
8 slices French bread, toasted
1 cup shredded Swiss cheese

In a Dutch oven or soup kettle, melt butter. Add onions and sugar; cook over low heat until lightly browned, about 1 hour.
Sprinkle flour over onions and stir until blended. Gradually stir in broth. Add the water, salt, dried onion, bouillon, garlic, salt and pepper.
Bring to a boil; cook and stir for 2 minutes. Reduce heat; cover and simmer for 45 minutes.
Ladle soup into ovenproof bowls. Top with a slice of toasted bread and sprinkle with cheese.
Place on a baking sheet. Bake at 400 degrees for 5 minutes.
