I have a heavy cast iron skillet that I use. I season the meat liberally with salt and pepper. Get the pan pretty hot (not high) and put about a tablespoon of butter and a tablespoon of oil (vegetable is what I usually have). The oil will mix with the butter and raise it's smoke point so the butter wont burn. When the butter is melted, I put the steak in there for about 3 minutes per side or until it is brown and crusty. That will get the steak rare-med. rare (depending on the thickness). I like my steak medium so I will usually take the skillet straight from the stove top to a 400 degree preheated over for a couple of minutes. When I take it out, I top it with some garlic/rosemary butter that I always have on hand, let it rest for a few minutes and enjoy.
