Ingredients
- 6 large yellow onions, thinly sliced
- 4 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon sugar
- 1 teaspoon salt
- 4 cups beef broth
- 1 cup chicken broth
- 1/2 cup dry white wine
- 1 teaspoon dried thyme
- 1 bay leaf
- Salt and pepper, to taste
- 1 baguette, sliced
- 2 cups grated Gruyère cheese
Instructions
- Heat the butter and olive oil in a large pot over medium heat. Add the onions, sugar, and salt. Cook, stirring occasionally, for about 40 minutes until the onions are deeply caramelized and golden brown.
- Add the white wine to deglaze the pot, scraping up any browned bits from the bottom. Let it cook for 2-3 minutes until the wine is mostly evaporated.
- Add the beef broth, chicken broth, thyme, and bay leaf. Bring to a boil, then reduce the heat and let it simmer for 20-25 minutes. Season with salt and pepper to taste.
- Preheat your oven broiler. Place baguette slices on a baking sheet and toast under the broiler until golden brown on both sides.
- To serve, ladle the soup into oven-safe bowls. Top with a slice of toasted baguette and a generous amount of grated Gruyère cheese. Place the bowls under the broiler until the cheese is melted and bubbly. Serve immediately.
Tips
For the best flavor, take your time caramelizing the onions—they should be a deep golden brown. You can also use a mixture of Gruyère and Parmesan cheese for extra flavor.
