Season steak liberally with coarse salt and freshly cracked pepper on both sides.
Prepare grates with oil right before placing steak onto the grill. Place steak onto the grill. Cook for 5 minutes. Flip. Cook an additional 5 - 7 minutes or until a thermometer reads 145°F for medium-rare or 160°F for medium.
Let the steaks rest at least 5-10 minutes before cutting into them to keep the juices from running out. The internal temperature will continue to rise 5-10° as it rests.
