French Onion Soup is a hearty classic soup recipe made from onions, beef broth, dry sherry, and seasonings, topped with toasted french bread and melted Gruyere cheese.
Add the butter to a large stock pot on medium heat with the onions and stir and cook until the onions are see through but not at all browned, about 30-35 minutes.
Add the broth, Worcestershire sauce, sherry, thyme, salt and pepper and bring to a boil, then reduce to a simmer for 30 minutes.
While the soup is simmering toast the French bread slices, and when ready ladle the soup into a soup bowl, top with french bread, then Gruyere cheese and place into a toaster oven or 375 degree oven for 10-12 minutes or until the cheese is melted and browned.
