PERFECT STEAK RECIPE:
preheat oven to 500.
bring steak to room temp, rub a little olive oil onto each side, as well as kosher salt and freshly ground pepper.
heat your cast iron skillet until just smoking, pour in a litle (very little) canola oil.
sear steaks 2 min each side, pop into oven for 3 minutes. remove, let sit, tented w/foil 5 min. Perfect.
ovens are the best way to cook steaks, because it's easiest to control the temperature.
edit: yes, sorry glen, you did post the oven method first, but mine's just a lil bit different.
