Ingredients
Soup
- 4 large onions, thinly sliced
- 3 tablespoons butter
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 6 cups beef broth
- 1 tablespoon Worcestershire sauce
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
Topping
- 4 slices baguette
- 1 cup shredded Gruyère or Swiss cheese
Instructions
- Heat fat: In a Dutch oven over medium heat, melt the butter with the olive oil to prepare the pan for caramelizing onions.
- Caramelize onions: Add the thinly sliced onions to the Dutch oven and cook slowly for 25 to 30 minutes, stirring frequently, until the onions become deeply caramelized and golden brown, providing a rich, sweet base for the soup.
- Add garlic: Stir in the minced garlic and cook for an additional 1 minute to release its fragrance without burning.
- Combine liquids and seasoning: Pour in the beef broth and Worcestershire sauce, then season with salt and black pepper to enhance the soup’s depth of flavor.
- Simmer the soup: Reduce heat and let the mixture simmer gently for 15 minutes, allowing the flavors to meld.
- Prepare bowls and toast bread: Ladle the hot soup into oven-safe bowls and top each with a slice of toasted baguette.
- Add cheese and broil: Sprinkle shredded Gruyère or Swiss cheese over the bread, then place the bowls under the broiler until the cheese melts and bubbles with a golden crust.
- Serve: Remove from the oven carefully and serve the soup hot, savoring the blend of caramelized onion, savory broth, crispy bread, and melted cheese.
Notes
- Slow caramelization of onions is essential for developing the soup’s signature deep, sweet flavor.
- Using homemade beef broth enhances the soup’s richness and authenticity.
- Mozzarella cheese can substitute for Gruyère if desired though it will alter the flavor profile.
