  • Saucepan

Ingredients
  

For the Sandwich

  • 8 slices crusty French bread
  • 8 slices Swiss cheese
  • 12 ounces thinly sliced roast beef
  • 2 medium yellow onions, thinly sliced
  • 4 tablespoons unsalted butter plus extra for spreading
  • 1 tablespoon olive oil

For the Au Jus

  • 2 cups low-sodium beef broth
  • 2 teaspoons Worcestershire sauce
  • 1 teaspoon soy sauce
  • 1 clove garlic, minced
  • 1 sprig fresh thyme
  • Salt, to taste
  • Black pepper, to taste

Instructions
 

  • Heat olive oil and 2 tablespoons of butter in a skillet over medium heat. Add the sliced onions and cook until caramelized, about 10-15 minutes.
  • Assemble the sandwiches by layering roast beef, caramelized onions, and Swiss cheese between two slices of French bread. Spread butter on the outer sides of the bread.
  • Grill the sandwiches in the skillet until the bread is golden and the cheese melts, about 3-4 minutes per side.
  • In a saucepan, combine beef broth, Worcestershire sauce, soy sauce, minced garlic, thyme, salt, and pepper. Simmer for 5 minutes.
  • Serve the sandwiches with the au jus for dipping.
