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
- In a large stock pot, melt butter and oil over medium heat.
- Add the onions and stir well to coat in the butter and oil. Cook over medium heat for 30-40 minutes, stirring occasionally until browning. Continue to cook for an additional hour on medium or medium low, stirring occasionally, until the onions are extremely soft and a deep, rich brown color.
- Add the sherry and cook for 1-2 minutes to allow some of it to evaporate.
- Add the broth, thyme, Worcestershire sauce, salt, and black pepper. Stir well. Add the cubed bread and stir to incorporate.
- Bring to a boil, then reduce heat, cover, and simmer on medium low for 30 minutes.
- For serving: Carefully transfer the soup to individual ramekins or small oven-proof bowls. Sprinkle with 2 tablespoons of shredded Swiss cheese. Add a slice of French bread on top, then top the bread with Gruyere cheese.
- Broil on high heat, about 3-4 inches from the heat source, for 3-4 minutes until the cheese is melted, being careful not to let it burn. Serve immediately.
- Alternatively, place the bread slices on a foil-lined baking sheet, top with Gruyere cheese, and broil for 2-3 minutes until melted. Serve with the broiled bread slice on top.
Notes
For a deeper flavor, use aged beef broth or add a splash of red wine.
Ensure the onions are caramelized properly for a rich flavor—patience is key!
To save time, consider using store-bought croutons topped with cheese instead of making the cubes.
