Let the steaks rest on the counter for at least 30 minutes before cooking. They must be room temperature.

Preheat the oven to 400°F.

Spray the steak lightly all over with cooking spray, then season both sides well with kosher salt and black pepper.

When the oven is ready, heat the skillet over high heat until the pan is very hot.

When hot, add the steaks and cook for 2 1/2 minutes. Turn over and cook for an additional 2 1/2 minutes.

Sear the sides of the steaks for about 1 minute until brown.

Place the steaks in the oven for 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).
