Preheat oven to 200 degrees.
At least one hour prior to cooking, liberally season steaks with salt and pepper. Let sit for one hour or up to three days. Keep steaks in refrigerator and do not let them reach room temperature.
Cook steak in oven until 20 degrees before desired temperature. I like mine 140-145, so we stopped at 120 degrees.
Right before removing steak from the oven, heat any neutral oil in skillet.
Take steaks out of the oven and transfer directly to the skillet. Add 2 Tablespoons butter. Sear the steak and butter in pan at the same time.
Turn steaks and baste with spoon constantly until crust/sear forms and final temperature is reached.
Rest steaks and tent with foil until ready to serve.
