Steps

• 1

  In a large bowl, whisk together the olive oil, balsamic vinegar, Traeger Prime Rib Rub, thyme, rosemary, and 3 cloves of garlic.

• 2

  Place the top round in a large resealable bag. Pour the balsamic mixture over the steak and rub to coat. Seal the bag and marinate in the refrigerator for at least 4 hours, or overnight.

• 3

  Remove the steak from the refrigerator 45 minutes before grilling to let it come to room temperature.

• 4

  In a medium bowl, combine the butter, blue cheese, and remaining clove of garlic. Mix well. Refrigerate until ready to use.

• 5

  When ready to cook, set the Traeger temperature to 500°F and preheat with the lid closed for 15 minutes.

  Insert the probe into the thickest part of the steak. Place the steak directly on the grill grates towards the front of the grill. Sear for about 6 minutes on each side until the internal temperature reaches 130°F for medium-rare, or until done to your desired temperature. Remove from the grill and let rest for 10-15 minutes.
