Place a seasoned cast iron skillet in the oven. Preheat the oven to 500 F.
In a small bowl, combine the black pepper, salt, and garlic. Rub the mixture all over the roast.
Carefully, with potholders or oven mitts, remove the skillet to a metal rack. Put the roast in the skillet.
Return the skillet to the oven and roast at 500 F for 25 minutes. Reduce the heat to 325 F and continue roasting for about 1 1/2 hours, or, for rare to medium-rare, until the roast reaches 130 F to 140 F on an instant thermometer or oven probe inserted into the center of the meat.
Remove from the oven, tent loosely with foil, and let the roast rest for 20 minutes.
