Enjoy a diner classic at home with these tender roast beef sandwiches served with savory au jus for dipping. This recipe guides you through creating a flavorful broth and assembling the perfect sandwich.

Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 large onion, thinly sliced
  • 2 cloves garlic, minced
  • 4 cups beef broth
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon dried thyme
  • Salt and black pepper to taste
  • 1.5 pounds thinly sliced roast beef (deli-style or homemade)
  • 4 crusty French rolls or sub rolls, split lengthwise
  • 1 cup shredded provolone cheese (optional)
  • Butter for toasting rolls

Instructions

  1. Heat olive oil in a large pot or Dutch oven over medium heat. Add the sliced onion and cook until softened and lightly browned, about 8-10 minutes.
  2. Add the minced garlic and cook for 1 minute more until fragrant.
  3. Pour in the beef broth, Worcestershire sauce, and dried thyme. Bring to a simmer, then reduce heat to low, cover, and let it gently simmer for at least 20 minutes to allow flavors to meld. Season with salt and pepper.
  4. While the au jus simmers, prepare the rolls. Lightly butter the cut sides of the rolls and toast them under the broiler or in a toaster oven until golden brown and slightly crisp.
  5. Add the thinly sliced roast beef to the simmering au jus. Let it heat through gently for about 5 minutes. Do not overcook the beef, as it can become tough.
  6. To assemble the sandwiches, place a generous portion of the warmed roast beef onto the bottom half of each toasted roll.
  7. If using cheese, place it over the roast beef. You can briefly place the sandwiches under the broiler to melt the cheese.
  8. Serve immediately with the warm au jus in small bowls for dipping.

Notes

  • For an even richer au jus, you can use beef drippings from a roast if you have them.
  • A splash of red wine can be added to the au jus for an extra layer of flavor.
  • Ensure your bread is sturdy enough to hold up to dipping.
