Ingredients
Scale
- 3 large white onions, sliced
- 2 tablespoons brown sugar
- 64 ounces beef broth (reduced sodium)
- 8 slices dry French bread
- 1 tablespoon Worcestershire sauce
- ⅓ cup dry sherry
- 4 sprigs fresh thyme (or 1 teaspoon dried thyme)
- 1 bay leaf
- 3 tablespoons butter
- ¾ cup Gruyère cheese, shredded
- ½ cup Emmental cheese, shredded
- 6 tablespoons fresh Parmesan cheese, shredded
- 1 clove garlic, minced
Instructions
- In a large non-stick pan, melt butter over medium-low heat. Add sliced onions and brown sugar. Cook, stirring occasionally, until onions are golden and caramelized, about 20 minutes.
- Place the caramelized onions into the slow cooker. Add beef broth, Worcestershire sauce, garlic, dry sherry, thyme, and bay leaf. Stir to combine.
- Cover and cook on low for 6-8 hours, allowing the flavors to meld and the soup to develop a rich taste.
- Preheat your broiler. Ladle the soup into oven-safe bowls. Top each bowl with a slice of dry French bread and a generous amount of Gruyère, Emmental, and Parmesan cheeses.
- Place the bowls under the broiler for 2-3 minutes, or until the cheese is melted, bubbly, and golden brown. Keep a close eye to avoid burning.
- Carefully remove from the oven and let cool slightly before serving.
