Scale
For the Soup:
- 2 tablespoons unsalted butter
- 2 tablespoons olive oil
- 4 large yellow onions, thinly sliced
- 1 teaspoon salt
- 1/2 teaspoon sugar (to aid caramelization)
- 2 cloves garlic, minced
- 2 tablespoons all-purpose flour
- 1/2 cup dry white wine (optional)
- 6 cups beef broth
- 1 bay leaf
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and freshly ground black pepper, to taste
For the Topping:
- 1 baguette, sliced into 1-inch thick rounds
- 2 cups grated Gruyère cheese
Instructions
- Caramelize the Onions:
- In a large pot or Dutch oven, melt the butter and olive oil over medium heat.
- Add the sliced onions and sprinkle with 1 teaspoon of salt and the sugar.
- Cook, stirring occasionally, for about 25-30 minutes, until the onions are deeply golden and caramelized. If the onions start to stick, you can add a splash of water to deglaze the pot.
- Add Garlic and Flour:
- Stir in the minced garlic and cook for an additional 1-2 minutes.
- Sprinkle the flour over the onions and stir well to coat. Cook for another 2-3 minutes to eliminate the raw flour taste.
- Deglaze and Simmer:
- If using, pour in the white wine to deglaze the pot, scraping up any browned bits from the bottom. Let it simmer for 2-3 minutes until slightly reduced.
- Add the beef broth, bay leaf, and thyme. Bring the soup to a boil, then reduce the heat and let it simmer, uncovered, for about 30 minutes.
- Season with salt and freshly ground black pepper to taste.
- Prepare the Bread and Cheese:
- While the soup is simmering, preheat your oven’s broiler.
- Arrange the baguette slices on a baking sheet and toast under the broiler until golden brown on both sides.
- Remove from the oven and set aside.
- Assemble and Serve:
- Remove the bay leaf from the soup.
- Ladle the hot soup into oven-safe bowls or crocks, leaving some space at the top.
- Place one or two toasted baguette slices on top of each bowl of soup.
- Sprinkle a generous amount of grated Gruyère cheese over the bread and soup.
- Place the bowls on a baking sheet and transfer them to the oven under the broiler. Broil until the cheese is melted, bubbly, and slightly browned, about 2-3 minutes. Watch closely to prevent burning.
- Carefully remove from the oven (the bowls will be hot) and serve immediately.
Notes
- For a deeper flavor, consider using a combination of beef and chicken broth.
- If you don’t have oven-safe bowls, you can melt the cheese on the bread slices separately under the broiler and then place them on top of the soup before serving.
- Adjust the amount of cheese and bread to your preference.
