Ingredients

Scale
  • 3 lb boneless prime rib roast
  • 2 tbsp olive oil
  • 2 tbsp Dijon mustard
  • 1 tbsp fresh rosemary, finely chopped
  • 1 tbsp fresh thyme leaves, finely chopped
  • 1 tbsp fresh parsley, finely chopped
  • 5 cloves garlic, minced
  • 2 tsp kosher salt
  • 1 tsp freshly cracked black pepper
  • 2 cups beef broth
  • 1/4 cup red wine (optional)
  • 1 tbsp Worcestershire sauce
  • 1 small yellow onion, sliced
  • 2 cloves garlic, smashed
  • Drippings from the prime rib roast
  • 6 crusty French rolls or baguette sections (45 inches each)
  • Butter, for toasting (optional)
  • 6 slices provolone or Swiss cheese
  • Horseradish sauce or creamy Dijon (optional, for serving)

Instructions

  1. Preheat oven to 475°F. Let prime rib sit at room temperature for 30-45 minutes.
  2. In a mixing bowl, combine olive oil, Dijon mustard, rosemary, thyme, parsley, minced garlic, salt, and black pepper to form a thick paste.
  3. Pat the roast dry with paper towels. Rub the herb paste all over the prime rib.
  4. Place the roast, fat side up, on a rack in a roasting pan. Roast for 20 minutes at 475°F.
  5. Lower oven to 325°F and continue roasting for 45-55 minutes, or until internal temperature reaches 130°F for medium-rare.
  6. Remove roast from oven, tent loosely with foil, and let rest for at least 20 minutes.
  7. For au jus: Set roasting pan with drippings over medium heat. Add onion and smashed garlic, sauté until golden. Add beef broth, red wine, and Worcestershire sauce. Simmer, scraping up crusty bits. Strain into a saucepan and keep warm.
  8. Slice prime rib as thinly as possible (about 1/8 inch thick).
  9. Split rolls or baguette sections. Butter lightly and toast on a skillet or griddle until golden brown.
  10. Lay prime rib slices on each roll. Top with cheese. Optional: spread with horseradish sauce or creamy Dijon.
  11. For melty cheese, broil sandwiches for 1-2 minutes until cheese is melted.
  12. Serve sandwiches immediately with hot au jus for dipping.

Notes

Let prime rib come to room temperature before roasting for even cooking. Use fresh herbs for best flavor, but dried herbs work in a pinch (use half the amount). If herb crust browns too quickly, tent with foil. Slice beef thinly for best sandwich texture; chilling the roast helps. Au jus can be made ahead and reheated. For gluten-free or dairy-free, swap bread and cheese as needed.
