I have made this several times, and it has always turned out awesome. To make this, you will need: a thick steak, salt, pepper, (and other seasoning if preferred), oil, butter, a stove, and a cast iron skillet.
Buy a 1 to 1&1/4 inch Rib Eye or NY Steak (marblely). Make sure the steak gets to room temperature before cooking.
Dry rub the steak. Pepper, salt, Lawrys or any dry steak rub
Heat the oven to 400 degrees.
Heat a cast iron skillet on stove, add a little canola oil to skillet (just cover the bottom) – make sure it is hot.
Drop a pad of butter in then drop the steak on top of it.
Sear 90 seconds, flip it for another 90 seconds then put the whole skillet in the oven for 9 minutes.
Remove from oven for rare to medium rare. 10 minutes for a less rare and so on…
Goes well with Cabernet (in this case, the Grove Street Meritage). Nice for the price ($10).
