Creating French Onion Soup is straightforward if you follow these simple steps:

1. Melt Butter and Oil: In a large pot, melt the butter and olive oil over medium heat.

2. Caramelize Onions: Once melted, add the sliced onions and sugar. Stir occasionally, cooking for about 30-35 minutes or until beautifully caramelized.

3. Add Garlic: When the onions are deep golden brown, stir in the minced garlic and cook for another 1-2 minutes.

4. Deglaze: Pour in the dry white wine to deglaze the pot, scraping the bits from the bottom. Let it simmer for about 5 minutes.

5. Add Broth: Add the beef broth and Worcestershire sauce. Season with salt and pepper. Bring it to a gentle boil, then reduce the heat to low. Allow it to simmer for about 30 minutes.

6. Toast Bread: While the soup simmers, preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet. Bake for about 5-7 minutes or until golden and crisp.

7. Cheese Preparation: Remove the soup from heat. Ladle the soup into oven-safe bowls. Place toasted bread on top of each bowl and generously sprinkle Gruyère cheese over each slice.

8. Broil the Soup: Place the bowls on a baking tray and broil in the oven for about 3-5 minutes or until the cheese is bubbly and golden brown. Watch closely to prevent burning.

9. Garnish: Once done, carefully remove from the oven and garnish with fresh thyme if desired.

10. Serve: Allow the bowls to cool slightly before serving. Enjoy your rich and satisfying French Onion Soup!
