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.
Over the hottest side of the grill, sear the roast for about 5 minutes per side, until the entire roast is nicely browned. In between turning the roast, keep the lid on the grill. When the roast is browned, move it to the cooler side of the grill and cook for another 8 to 10 minutes with the lid on.
