Units of measurement:
1 (6 lb) boneless prime rib roast
5 Clove garlic, coarsely chopped
2 Tablespoon red wine vinegar
1/2 Cup fresh parsley, coarsely chopped
1 Tablespoon fresh rosemary needles
1/2 Cup olive oil or vegetable oil
As Needed Traeger Prime Rib Rub
4 Cup beef broth, preferably low sodium, divided

As Needed pepper


  • 1

    Tie the roast at 2 inch intervals with butcher's twine.

  • 2

    In a blender jar or small food processor, combine the garlic, red wine vinegar, parsley and rosemary. Add a couple tablespoons of the oil and pulse to chop the garlic and herbs. Add the remaining oil in a small stream until the mixture is well blended.

  • 3

    Place roast into a large resealable plastic bag and pour the herb mixture over the roast, coating it on all sides.

  • 4

    Transfer the roast to the fridge and marinate for 2 hours.

  • 5

    Remove the roast from plastic bag and discard the marinade. Liberally season the roast on all sides with Traeger Prime Rib Rub and let the roast come to room temperature.

  • 6

    Place the roast, fat-side up, in a v-shaped rack in a roasting pan. Pour 4 cups beef broth into the bottom of the pan.

  • 7

    When ready to cook, set Traeger temperature to 400°F and preheat, lid closed for 15 minutes.

    400 ˚F / 204 ˚C

  • 8

    Arrange the pan with the prime rib on the grill grate and roast for 30 minutes.

    400 ˚F / 204 ˚C


  • 9

    After 30 minutes, reduce the temperature to 225℉ and continue to cook until the internal temperature of the roast reaches 130℉ for medium-rare, about 2 to 3 hours.

    225 ˚F / 107 ˚C

    130 ˚F / 54 ˚C

    Super Smoke

  • 10

    Transfer the roast to a cutting board and let rest, loosely covered with foil, for 20 minutes.

  • 11

    For the Beef Au Jus: Place the roasting pan over medium heat and deglaze with 2 cups beef stock. Using a wooden spoon scrape up all the brown bits from the bottom of the pan.

  • 12

    Strain the jus into a small saucepan discarding the solids and skim off any fat that rises to the top. Taste and simmer over medium heat to reduce if needed (if the jus tastes a little weak, reducing will concentrate the flavor). Taste the jus for seasoning, adding salt and pepper as needed. Rewarm before serving.

  • 13

    Carve the roast into thick slices and serve with the beef au jus. Enjoy!
