Ingredients
| Ingredient | Quantity |
| Onions (thinly sliced) | 4 large |
| Butter | 4 tablespoons |
| Beef broth (or vegetable broth) | 6 cups |
| Dry white wine | 1 cup |
| Thyme (fresh or dried) | 1 teaspoon |
| Baguette (sliced) | 1 |
| Gruyère cheese (shredded) | 1 cup |
| Salt | to taste |
| Pepper | to taste |
Step-by-Step Instructions
- Caramelize the Onions: In a large pot, melt the butter over medium heat. Add the sliced onions and cook them slowly for about 20-30 minutes, stirring frequently until they are golden brown. This step brings out the natural sweetness of the onions!
- Add the Broth: Pour in the beef broth and white wine. Stir in the thyme and season with salt and pepper. Bring the mixture to a gentle simmer and let it cook for another 20-30 minutes to develop the flavors.
- Prepare the Baguette: While the soup simmers, preheat your oven to 350°F (175°C). Place the baguette slices on a baking sheet and toast them for about 10 minutes or until they are golden brown.
- Assemble the Soup: Once the soup is ready, ladle it into oven-safe bowls. Place a slice of toasted baguette on top of each bowl and sprinkle generously with Gruyère cheese.
- Bake: Put the bowls in the oven and bake for about 10-15 minutes or until the cheese is bubbly and golden brown. Keep a close eye to avoid burning!
- Serve: Carefully remove the bowls from the oven and let them cool for a minute. Serve hot and enjoy your delicious Soupe à l’Oignon!
