Ingredients
Scale
- 2 tablespoons unsalted butter
- 2 tablespoons extra-virgin olive oil
- 4 large onions, sliced thin
- 1 tablespoon dry sherry
- 4 cups low-sodium beef broth
- 1 tablespoon chopped, fresh thyme
- ½ teaspoon worcestershire sauce
- ¼ teaspoon kosher salt
- ¼ teaspoon black pepper
- 2 (½-inch) thick slices french bread, cut into small cubes (about 1 cup)
- ½ cup shredded swiss cheese
- 4 (½-inch) thick slices french bread
- 4 slices gruyere cheese
Instructions
- Melt butter and olive oil in a large stock pot over medium heat.
- Add the sliced onions, coating them well. Cook for 30-40 minutes until browned, stirring occasionally. Lower the heat and continue cooking for another hour until the onions are very soft and deep brown, making sure they don't burn.
- Stir in the dry sherry and let it evaporate for 1-2 minutes.
- Pour in the beef broth, thyme, Worcestershire sauce, salt, and black pepper. Mix well.
- Incorporate the cubed bread by stirring it into the soup mixture.
- Bring the soup to a boil, then reduce the heat, cover, and let it simmer on medium-low for 30 minutes.
- To serve, spoon the soup into ramekins or small oven-proof bowls. Top each with 2 tablespoons of shredded Swiss cheese, a slice of French bread, and a slice of Gruyere cheese on top.
- Broil the soup for 3-4 minutes until the cheese melts and is bubbly, watching closely to avoid burning. Serve hot.
Notes
For a deeper flavor, cook the onions until they reach a very dark brown color without burning.
Use a mix of Swiss and Gruyere cheese for a richer topping.
Make sure to use low-sodium beef broth to control the saltiness of the soup.
