Ingredients

• 1 tablespoon olive oil
• 3 tablespoons unsalted butter
• 4 large yellow onions, thinly sliced
• 1 teaspoon sugar
• 1 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• 8 cups low-sodium beef broth
• 1/2 cup water
• 2 teaspoons fresh thyme leaves (or 1 teaspoon dried thyme)
• 1 bay leaf
• 1 baguette, sliced and toasted
• 2 cups grated Gruyère cheese

Instructions

Prepare the Onions

1. Heat Butter and Oil: In a large pot over medium heat, combine the olive oil and butter until melted and shimmering.
2. Caramelize Onions: Add the sliced onions, sugar, and salt to the pot. Stir to combine.
3. Slow Cooking: Cook the onions for 30-40 minutes, stirring occasionally, until they are deeply caramelized and golden brown. Adjust the heat to prevent burning.

Make the Soup

4. Add Seasonings: Stir in the thyme, black pepper, and bay leaf. Cook for 1 minute to release the aromatics.
5. Add Broth and Simmer: Pour in the beef broth and water. Bring the mixture to a boil, then reduce the heat to low. Let the soup simmer uncovered for 30 minutes to allow the flavors to meld.
6. Discard Bay Leaf: After simmering, remove and discard the bay leaf.

Prepare the Bread

7. Toast Baguette: Preheat your oven broiler. Arrange the baguette slices on a baking sheet. Toast them under the broiler for 1-2 minutes per side, or until golden brown.

Assemble the Soup

8. Ladle Soup: Divide the soup among oven-safe bowls.
9. Add Bread and Cheese: Place a toasted baguette slice on top of the soup in each bowl. Generously sprinkle grated Gruyère cheese over the bread.
10. Broil to Perfection: Place the bowls under the broiler for 2-3 minutes, or until the cheese is melted, bubbly, and golden brown.

Serve

11. Garnish: Carefully remove the bowls from the oven. Garnish with fresh thyme leaves if desired.
