Servings: 8
Ingredients
- 6 tablespoons shredded Parmesan cheese
- 64 ounces reduced-sodium beef broth
- ¾ cup shredded Gruyere cheese
- 2 tablespoons brown sugar
- 1 clove garlic minced
- 8 slices stale or dry French bread
- 3 large white onions sliced
- 1 tablespoon Worcestershire sauce
- 4 sprigs fresh thyme or 1 teaspoon dried thyme
- ½ cup shredded Emmental cheese
- ⅓ cup dry sherry
- 3 tablespoons butter
- 1 bay leaf
Instructions
- In a spacious non-stick skillet, gently sauté the sliced onions with butter and brown sugar over medium-low heat until the onions reach a deep golden hue and are thoroughly caramelized, which should take approximately 20 minutes. Transfer the caramelized onions to a 6-quart slow cooker and incorporate the beef broth, Worcestershire sauce, minced garlic, dry sherry, thyme, and bay leaf. Allow the soup to cook on a low setting for 6 to 8 hours to develop robust flavors. Discard the bay leaf, then portion the soup into serving bowls. Place a slice of dry French bread atop each portion and generously sprinkle with Gruyere, Emmental, and Parmesan cheeses. Broil the bowls for 2 to 3 minutes until the cheese is fully melted and beautifully golden.
Notes
To prepare the bread, slice it into ½-inch thick pieces and toast in a 300°F oven for 5 to 7 minutes until dry. Let cool completely before serving with the soup.
