Description

This juicy, tender, and flavorful prime rib is the ultimate centerpiece for any holiday or special occasion. A simple seasoning blend and slow roasting method ensure a perfectly cooked, melt-in-your-mouth roast every time.


Ingredients

Scale
  • 1 (5-7 lb) bone-in prime rib roast
  • 2 tbsp kosher salt
  • 2 tbsp black pepper (freshly ground)
  • 2 tbsp garlic powder
  • 1 tbsp onion powder
  • 1 tbsp fresh rosemary (chopped)
  • 1 tbsp fresh thyme (chopped)
  • 2 tbsp olive oil or softened butter
  • 2 tsp Dijon mustard (optional, adds a subtle tang)

Instructions

  1. Prepare the Roast:

    • Take the prime rib out of the fridge at least 2 hours before cooking to bring it to room temperature.
    • Pat the roast dry with paper towels.
  2. Season the Meat:

    • Mix together salt, pepper, garlic powder, onion powder, rosemary, and thyme.
    • Rub the roast all over with olive oil or butter, then coat it evenly with the seasoning mix.
    • If using Dijon mustard, rub a thin layer over the meat before applying seasonings.
  3. Preheat & Roast:

    • Preheat your oven to 500°F (260°C).
    • Place the prime rib on a roasting rack in a large roasting pan, fat side up.
    • Roast at 500°F for 15 minutes to create a crispy crust.
  4. Slow Roast:

    • Reduce oven temperature to 250°F (120°C) and continue cooking until the internal temperature reaches:
      • Rare: 120°F (49°C)
      • Medium-rare: 130°F (54°C)
      • Medium: 140°F (60°C)
    • This usually takes about 15-20 minutes per pound.
  5. Rest & Serve:

    • Remove the roast from the oven and tent it loosely with foil.
    • Let it rest for at least 30-45 minutes to allow the juices to redistribute.
    • Slice and serve with au jus and horseradish sauce.

Notes

  • Use a meat thermometer for the most accurate doneness.
  • For a crispier crust, sear the roast in a hot pan before roasting.
  • Save the pan drippings to make a rich and flavorful au jus.
