If you have a probe meat thermometer with an alarm, I recommend using it.', 'Preheat oven to 500 degrees.', 'Cut all visible fat from the outside of the meat. Rub the entire outside of the roast with salt, pepper, or seasonings of your choice, such as thyme, garlic powder, etc. (If using a probe thermometer insert it into center of the meat.
