Ingredients:
- 8 slices crusty French bread
- 8 slices Swiss cheese
- 340 grams thinly sliced roast beef
- 2 medium yellow onions, thinly sliced
- 60 grams unsalted butter, plus extra for spreading
- 15 millilitres olive oil

- 1 garlic clove, minced
- 1 sprig fresh thyme
- Salt, to taste
- Black pepper, to taste
Directions:
- In a large skillet over medium heat, melt 1 tablespoon unsalted butter with olive oil. Add thinly sliced onions and cook, stirring frequently, until deeply golden and fully caramelized, about 12 to 15 minutes. Transfer onions to a plate and set aside.
- Wipe the skillet clean. In a small saucepan, combine beef broth, Worcestershire sauce, soy sauce, minced garlic, and thyme. Bring to a simmer over medium heat for 5 minutes. Season with salt and black pepper to taste. Strain the liquid through a fine sieve and keep the au jus warm.

- Spread unsalted butter evenly over the exterior sides of each assembled sandwich. Heat a clean skillet over medium-low. Grill sandwiches in batches until the bread is golden and crisp, and cheese is fully melted, about 3 to 4 minutes per side.
- Transfer sandwiches to a cutting board, slice if desired, and serve immediately with warm au jus on the side for dipping.
