Ingredients
4 large yellow onions, thinly sliced
3 tablespoons unsalted butter
1 tablespoon olive oil
1 teaspoon kosher salt
1/2 teaspoon black pepper
3 cloves garlic, minced
1 tablespoon all-purpose flour
1/2 cup dry white wine
6 cups beef stock
2 teaspoons Worcestershire sauce
3 sprigs fresh thyme
1 bay leaf
12 baguette slices
2 cups shredded Gruyère cheese
1/4 cup grated Parmesan cheese
Instructions
1. Peel and thinly slice the onions, keeping the slices as even as possible.
2. Heat the butter and olive oil in a large Dutch oven over medium heat. Add the onions and salt, then cook for 10 to 15 minutes until softened.
3. Reduce the heat to medium-low and cook the onions for 40 to 50 minutes, stirring often, until deeply golden and caramelized.
4. Stir in the garlic and black pepper, then cook for 1 minute. Sprinkle in the flour and stir for 1 to 2 minutes.
5. Pour in the white wine and scrape the browned bits from the bottom of the pot. Simmer for 3 to 4 minutes.
6. Add the beef stock, Worcestershire sauce, thyme, and bay leaf. Simmer uncovered for 25 to 30 minutes.
7. Toast the baguette slices until crisp on both sides.
8. Ladle the hot soup into oven-safe bowls, top with baguette slices, Gruyère, and Parmesan.
9. Broil until the cheese is melted, bubbling, and golden. Let the bowls rest for 2 minutes before serving.
Notes
Use a wide, heavy pot so the onions caramelize evenly instead of steaming too much.
Do not rush the onions; the deep golden color is what gives the soup its classic flavor.
Toast the baguette well before adding it to the soup so it holds up under the melted cheese.
