Turn with tongs and cook another 30 seconds, then put the pan straight into the oven.4 Roast for 2 minutes, then flip steak over and roast for 2 more minutes.5 (This time is for a medium rare steak. If you prefer medium, add a minute to both of the oven turns.)6 Remove steak from pan, cover loosely with foil, and rest for 2 minutes.
