1 Cover the grill and allow the roast to cook for about 1 hour for a medium rare 2-3 lb. roast. 2  The temperature of the grill should be around 400Â° F. Check for doneness with a meat thermometer. 3  For medium rare - 145Â°, medium - 160Â°, and well done - 170Â°. 4  Cook for approximately 1 1/2 for medium and 2 hours for well done.
Grill indirect for approximately one hour. Remove the roast from the grill and increase the direct side of the grill to high. Grill each side of the roast until the internal temperature is 120-130 degrees for rare. Remove the roast from the grill and cover the roast with foil for 15 minutes. Slice thinly and serve.
