Special equipment: seasoned cast iron skillet (10 inches in diameter)
Preheat the oven to 350 degrees F. Coat the steak with pepper and then with a heavy sprinkling of salt. Heat the cast iron skillet until extremely hot (approximately 10 minutes). Add oil to the pan. Sear the steak on the first side 1 to 2 minutes until it develops a nice crust. Flip it, baste it with the oil, top with butter, garlic and thyme and place in the oven. Check every 2 minutes; cook to desired temperature (approximately 2 minutes for medium rare). Let the meat rest until the juices redistribute and slice across the grain on a slight bias.

Warning: Please heat your pan cautiously. 10 minutes or under will suffice. Any longer and the oil could catch fire! Have a fire extinguisher ready, just in case.
