Instructions:
- Caramelize the Onions: Thinly slice the onions and cook them slowly in butter over low heat until golden brown and caramelized, stirring occasionally to prevent burning.
- Deglaze the Pan: If using, add a splash of dry sherry or white wine to the pan to deglaze it, scraping up any browned bits from the bottom for added flavor.
- Simmer with Broth: Pour in the beef broth and add fresh thyme leaves, salt, and pepper. Simmer the soup for 20-30 minutes to allow the flavors to meld together.
- Prepare the Crocks: Arrange oven-safe crocks or bowls on a baking sheet. Place a few toasted baguette slices in each crock and ladle the hot soup over them.
- Top with Cheese: Generously sprinkle grated Gruyère or Swiss cheese over the soup in each crock, covering the surface completely.
- Broil to Perfection: Preheat the broiler and place the baking sheet with the crocks under the broiler until the cheese is melted, bubbly, and golden brown.
- Serve and Enjoy: Carefully remove the crocks from the oven and serve the Best French Onion Soup piping hot, garnished with additional fresh thyme leaves if desired.
