Let the steaks rest on the counter to come up to room temperature at least 30 minutes before ready to cook
Preheat the oven to 400°F.
Spray the steak lightly all over with olive oil, then season both side generously with kosher salt and black pepper.
When the oven is ready, heat the a heavy skillet or cast iron skillet over high heat until the pan is very hot.
When hot, add the steaks and cook, without moving for 2 ½ minutes. Turn over and cook an additional 2 to 2-½ minutes.
Sear the sides of the steaks for about 1 minute so it's browned all over.
Place the steaks in the oven for about 4 to 5 minutes, then check them with the meat thermometer inserted into the side of the steak.
Remove when the steaks read 125° F for Medium Rare, or 130° F for medium.
Let them rest 5 to 10 minutes before serving (meat temperature will rise 5 to 10 degrees after it is removed from the oven).
