  • cups ghee melted
  • ¼ cup Traeger's Prime Rib Rub
  • 10-12 lb prime rib roast
  • 1 Tbs dried rosemary chopped


The night before...

  • The night before serving the prime rib roast, melt the ghee and add the Traeger Prime Rib Rub. Mix the ghee and Traeger seasoning well with a small whisk.
  • Place the rib roast in the shallow baking pan bone side down.
  • Then pour the ghee/seasoning mixture all over the roast coating it well.
  • Sprinkle the roast with salt, pepper, and rosemary.
  • Cover the roast and refrigerate it overnight to marinate.

Roasting Instructions

  • About 3 hours before putting the roast in the oven, take it out of the refrigerator and set it on the counter to warm to room temperature.
  • After 3 hours, preheat the oven to 500°.
  • Set the timer for 20 minutes. Cook the roast at 500° for 20 minutes.
  • When the 20 minutes is up, without opening the oven door, turn the oven temperature down to 320°.
  • Continue to cook the roast for 320° for 13-15 minutes per pound for medium-rare.
  • For medium-rare, the internal meat temperature should read 120°. (For a rare roast, the internal meat temperature should be 115°)
  • Once the roast is out of the oven, let it rest for about 10 minutes before slicing. This allows the juices to distribute evenly throughout the roast.
  • Finally, slice, serve, and enjoy!
