When the butter is melted and has turned a golden brown, place the steaks into the skillet. Let them sear for about 1 minute (less if you prefer more of a rarer steak, and if thinner than 1-in. thickness.)
Flip and let sear on other side for the same amount of time.
Place skillet in the oven for about 3 minutes and then serve immediately or steak will continue to cook.
