  • Total Time: 1 hour 20 minutes
  • Yield: 6 servings

Ingredients

Prime Rib Roast

  • 4-5 pound Prime Rib Roast

Seasoning Mix

  • 1/4 teaspoon dried parsley flakes
  • 1/4 teaspoon Italian seasoning
  • 1/4 teaspoon dried basil
  • 1/4 teaspoon black pepper
  • 1 teaspoon salt

Additional Seasonings

  • 1 Tablespoon Worcestershire Sauce
  • Garlic powder, to taste
  • Onion salt, to taste

Au Jus

  • 1 beef bouillon cube
  • 1 cup water
  • Au Jus Packet (optional, for extra au jus)

Instructions

  1. Preheat Oven: Preheat your oven to 450°F (232°C) to prepare for searing the prime rib roast.
  2. Bring Meat to Room Temperature: Remove the prime rib from the refrigerator and allow it to come to room temperature, which helps ensure even cooking.
  3. Mix Seasonings: In a small bowl, combine the dried parsley flakes, dried basil, black pepper, Italian seasoning, and salt. Set this seasoning mix aside.
  4. Sear the Roast: Place the prime rib roast fat side up on a rack in an ungreased roasting pan. Bake at 450°F for 15 minutes to sear and lock in juices.
  5. Lower Oven Temperature: Reduce the oven temperature to 250°F (121°C) to continue slow roasting.
  6. Apply Worcestershire and Additional Seasonings: Take the roast out of the oven and rub it all over with Worcestershire sauce. Sprinkle a generous amount of onion salt and garlic powder evenly, rubbing it into the meat thoroughly.
  7. Season with Herb Mix: Sprinkle the prepared herb seasoning mix over the roast, rubbing it into all sides to ensure robust flavor.
  8. Slow Roast: Return the roast to the oven and cook for approximately 15 minutes per pound, or until a digital thermometer inserted into the thickest part reads 115-120°F (46-49°C) for medium rare.
  9. Prepare Au Jus: Remove the roast from the pan. Skim excess fat from the pan drippings. Dissolve the beef bouillon cube in 1 cup of water and add it to the drippings to make a flavorful au jus sauce.
  10. Make Additional Au Jus (Optional): If desired, prepare the au jus packet according to package instructions for extra sauce.
  11. Serve with Au Jus: To ensure each slice of prime rib is served at preferred temperature and juiciness, briefly dip slices into hot au jus warmed in a skillet as you carve.

Notes

  • Bringing the roast to room temperature before cooking promotes even roasting.
  • Use a digital meat thermometer for accurate internal temperature reading.
  • Cooking times may vary slightly based on oven calibration and roast size.
  • Rest the roast loosely covered with foil for 15-20 minutes before carving to allow juices to redistribute.
  • Au jus enhances moisture and adds depth of flavor to the sliced prime rib.
  • Optional au jus packet can be used for convenience and extra sauce quantity.
