Description
A comforting sandwich featuring melted Swiss cheese, caramelized onions, and thinly sliced roast beef, served with a savory au jus for dipping.
Ingredients
Scale
- 8 slices crusty French bread (about 8 oz / 225 g total)
- 8 slices Swiss cheese
- 12 ounces thinly sliced roast beef (about 340 g)
- 2 medium yellow onions, thinly sliced
- 4 tablespoons unsalted butter, plus extra for spreading
- 1 tablespoon olive oil
- 2 cups low-sodium beef broth
- 2 teaspoons Worcestershire sauce
- 1 teaspoon soy sauce
- 1 garlic clove, minced
- 1 sprig fresh thyme
- Salt, to taste
- Black pepper, to taste
Instructions
- In a large skillet over medium heat, melt 1 tablespoon of butter with 1 tablespoon of olive oil. Add the sliced onions and a pinch of salt. Sauté until deeply caramelized and golden brown, about 12 to 15 minutes. Transfer the onions to a plate and set aside.
- In a small saucepan, combine beef broth, Worcestershire sauce, soy sauce, minced garlic, and fresh thyme. Bring to a gentle simmer for 5 minutes. Strain and keep warm over low heat.
- Arrange 4 slices of bread on a work surface, layering each with Swiss cheese, roast beef, caramelized onions, and another slice of cheese. Top with the remaining bread slices.
- Spread unsalted butter evenly on the outsides of the sandwiches.
- Grill sandwiches in a skillet over medium heat for 3 to 4 minutes per side until crisp and golden. Adjust heat if necessary to ensure cheese melts.
- Slice sandwiches in half and serve with warm au jus for dipping.
