Ingredients
Soup Ingredients
- 4 to 5 large sweet onions (about 2lbs), sliced
- 6 tablespoons unsalted butter
- 1 teaspoon chopped fresh thyme
- ½ teaspoon salt
- ½ teaspoon freshly cracked black pepper
- 3 tablespoons bourbon
- 2 garlic cloves, minced
- ⅓ cup dry sherry
- 6 cups beef stock
- 1 to 2 sprigs of fresh thyme (plus extra for garnish)
Toppings
- 8 ounces Gruyère cheese, freshly grated
- Bread slices, cut into heart shapes
- Olive oil, for brushing bread
Instructions
- Caramelize the Onions: Heat a large pot over low heat and add the butter. Once melted, stir in the sliced onions, salt, pepper, and chopped thyme. Cook, stirring frequently, until the onions soften and start to caramelize, about 20 minutes. Stir in the bourbon, then continue cooking and stirring for another 20 to 30 minutes until the onions are deeply caramelized and golden in color. Add the minced garlic and stir to combine.
- Add Liquids and Simmer: Stir in the dry sherry and cook for about 5 minutes. Add the beef stock and fresh thyme sprigs. Bring the soup to a boil, then reduce the heat to a simmer. Cook uncovered for 15 to 20 minutes, allowing the broth to reduce and thicken slightly.
- Prepare Heart Croutons: While the soup simmers, preheat your oven to 350°F (175°C). Using a heart-shaped cookie cutter, cut out hearts from the bread slices. Place them on a baking sheet and brush lightly with olive oil. Bake for 10 to 12 minutes, or until golden and crisp.
- Assemble the Soup: Ladle the hot soup into oven-safe ramekins or crocks. Sprinkle a layer of grated Gruyère cheese on top of the soup, then place one heart-shaped crouton over the cheese. Add another generous sprinkle of Gruyère on top of the crouton.
- Broil the Cheese: Set your oven broiler to high and place a rack in the center. Place the crocks on a baking sheet and broil them for 2 to 3 minutes, or until the cheese is melted, bubbly, and golden brown.
- Garnish and Serve: Carefully remove the crocks from the oven, garnish with additional fresh thyme if desired, and serve immediately while hot and cheesy.
Notes
- For best results, use sweet onions such as Vidalia or Walla Walla for a naturally sweeter caramelized flavor.
- Keep a close eye on the onions while caramelizing to prevent burning; low and slow is key.
- You can substitute beef stock with vegetable broth for a lighter variation, though the flavor will be less rich.
- Gruyère cheese melts beautifully and adds nuttiness, but Swiss or mozzarella can be alternatives.
- Use sturdy bread for the croutons to ensure they stay crisp and hold up under the cheese.
- Be cautious when broiling as cheese can burn quickly; stay close to the oven during this step.
