Sear each side of the steak in the pan for 2 â 5 minutes; peek underneath to know when to flip. You want it brown but not black (i.e., burnt). If you like your steak rare to medium rare, you can often stop here. Just check the internal temperature of the steak with your meat thermometer (see above). If you like your steak medium to well done, put it in the oven on a small rack over a baking sheet lined with tinfoil to roast for another 5-15 minutes. (Again, with the meat thermometer, youâll know exactly when to take it out.)
Place a tablespoon of unsalted butter on each of the steaks and place the skillet directly in the oven. Turn the heat down to 125 degrees Fahrenheit (51.6 degrees Celsius). Cook the steaks in the oven for eight to 12 minutes. Cut into one of the steaks to see if it's cooked to your taste. Remove the steaks from the oven and allow them to rest for 10 to 15 minutes to allow the juices to redistribute throughout the steak [source: Garten].
