One hour before cooking, bring the steaks to room temperature by taking them out on the counter for 1-2 hours. Generously salt and pepper the steaks at least 40 minutes prior to cooking, OR right before cooking.
Preheat the gas grill well, at least 15 minutes.
Clean the grates and lightly oil the grates. Here’s how I do it: I pour a little vegetable oil on a piece of paper towel. And rub the oiled paper towel on grates, using a pair of kitchen tongs. (You can watch it in action in the video below.)
Place the prepared steak on the grill. Cook it for about a minute, then turn it quarter turn for a nice diamond grill marks, if desired. Flip and cook for another minute. Then continue to grill the steak until desired doneness, flipping every minute or two. I like my steaks medium rare, which means I cook mine till 130°F.
Transfer onto a clean plate, cover and rest for at least 10 minutes before slicing and serving. If desired, place a slice of butter on top of the steak before covering.
