Place your steaks on a plate and liberally season with kosher salt. Allow them to come up to room temperature before cooking, about 30 minutes.
Preheat your oven to 500 degrees.
Coat a cast iron skillet or oven safe pan with a coat of oil. Place over high heat. When hot, place the steaks on leaving room between them.
Sear for 2 minutes, then flip and sear for another minute.
Immediately place into the oven. Allow 3 to 5 minutes for the steak to finish or until they an internal temperature of 5 degrees below your final temperature (120 for rare, 130 for medium rare, 140 for medium, 150 for medium well and 160 for well done).
Allow the steak to rest on a plate for 5 minutes before cutting.
