I just season well with salt, pepper and olive oil. Heat the pan up with nothing in it, add the steak make sure you leave it alone until nice and brown on the bottom, flip it over and do the same then turn the heat down and cook through to you're liking.

Then I take the steak out and rest it, deglaze the pan with wine or stock or even both and then because I'm lazy I through in a little water and gravox to thicken it up!
