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.
1 Move the meat to a place on the grill so that it is not over direct heat (you can shut off the burners on one side). 2  Grill on each side until the middle is medium rare (125-130 degrees F), about 20 more minutes. 3  If it is a large roast, it will take longer to cook.
