Roasting a Natural Angus prime rib roast for 3+ hours with rosemary, thyme, and butter leads to an exceptionally tender and flavorful meal.


1 8lb. Aspen Ridge rib roast

½ C Kosher salt

4 sprigs thyme

3 sprigs rosemary

4 Tbsp butter (softened)

Pepper to taste


  1. Cover rib roast in kosher salt and allow to rest overnight in the refrigerator, uncovered.
  2. Preheat oven to 200 degrees F.
  3. Remove from fridge and cover rib roast in butter, making sure to coat all sides. Place the sprigs of rosemary and thyme in the roasting pan along with the rib roast. Roast in the oven for approximately 3 ½ hours, or until the internal temperature reaches 125 degrees F. Remove the roast from the oven and tent with aluminum foil while it rests for 20 minutes.  
  4. Heat a pan over the stove until it’s nice and hot, then sear the rib roast until you get an even browned color on all sides. Set aside and rest for 10 minutes. For medium-rare, final temp should be 135F, for medium, 145F. Carve and serve.
