  • 2 white onions, cut into 1-inch (2.5 cm) slices
  • 1 prime rib (approximately 6 lbs/2.7 kg)
  • ¼ cup Dijon mustard
  • 1 1/2 cups kosher salt
  • ⅓ cup prepared horseradish
  • 2 tablespoons mustard seeds
  • 2 tablespoons fresh thyme
  • 2 tablespoons fresh rosemary
  • 2 tablespoons ground black pepper
  • 5 bay leaves, crumbled
  • 3 egg whites

Step-by-Step Instructions:

  1. Preheat Oven: Begin by preheating your oven to 450°F (230°C) to ensure it reaches the optimal temperature for roasting the prime rib to perfection.
  2. Prepare Onions: Arrange the sliced onions in the bottom of a roasting pan, creating a bed for the prime rib to rest on during the cooking process.
  3. Brush with Mustard: Generously brush the prime rib with Dijon mustard, ensuring that the entire surface is evenly coated for maximum flavor infusion.
  4. Prepare Salt Mixture: In a large bowl, combine the kosher salt, prepared horseradish, mustard seeds, fresh thyme, fresh rosemary, ground black pepper, and crumbled bay leaves. Mix well until the ingredients are evenly distributed, creating a fragrant and flavorful salt mixture.
  5. Apply Salt Mixture: Add the egg whites to the salt mixture and stir until the mixture resembles wet sand. Press the salt mixture evenly over the fat side and ends of the prime rib, forming a crust that will seal in the juices and enhance the overall flavor of the meat.
  6. Roast: Place the prepared prime rib, bone side down, over the bed of onions in the roasting pan. Roast in the preheated oven for 15 minutes to sear the exterior and lock in the juices.
  7. Reduce Heat: After 15 minutes, reduce the oven temperature to 325°F (160°C) and continue roasting the prime rib for approximately 20 minutes per pound (450 g), or until an instant-read thermometer inserted into the thickest part of the roast registers 130°F (55°C) for medium-rare doneness.
  8. Rest: Once the prime rib reaches the desired doneness, transfer it to a cutting board and allow it to rest for at least 20 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring a tender and juicy texture.
  9. Slice and Serve: After resting, carefully remove and discard the salt crust from the prime rib. Slice the meat against the grain into thick, juicy portions, and serve alongside your favorite side dishes and accompaniments.
