Preheat your oven for 200ºF (or as low as it goes).
Season your steaks generously on both sides and place on a rack over a baking sheet.
Cook until the internal temp reaches your desired doneness (115ºF for rare, 125ºF for medium rare, 135ºF for medium). For medium rare, this will be 40 mins per pound of steak, based on the size of the largest steak. For an average supermarket steak, this will be approximately 20 minutes.
5 minutes before your steak is done, preheat a cast iron skillet with a high temp oil like grapeseed or canola.
When the steaks are done, sear the steaks for 15-30 seconds a side on all sides, or until your desired color is reached.
Rest steaks for 3-5 minutes, then serve.
