What is a recipe for French onion soup?

Ingredients:

- 3 tablespoons unsalted butter

- 2 large onions, thinly sliced

- 1/2 teaspoon salt

- 1/4 teaspoon black pepper

- 1/4 cup dry white wine

- 4 cups beef broth

- 1 bay leaf

- 2 slices French bread, toasted

- 1/2 cup shredded Gruyère cheese

Instructions:

1.) In a large pot or Dutch oven over medium heat, melt the butter. Add the onions, salt, and pepper and cook, stirring occasionally, until the onions are softened and caramelized, about 25-30 minutes.

2.) Add the white wine and cook for a few minutes, until the liquid is reduced by half.

3.) Stir in the beef broth and bay leaf. Bring to a boil, then reduce heat and simmer for 15 minutes.

4.) Preheat your oven's broiler.

5.) Ladle the soup into oven-safe bowls or crocks. Top each bowl with a slice of toasted French bread and sprinkle with Gruyère cheese.

6.) Broil the soup until the cheese is melted and bubbly, about 2-3 minutes.

Serve the soup immediately and enjoy!
