Preheat oven-safe cast iron skillet (or other oven-friendly pan) over medium-high to high heat. Preheat the oven to 350.
Blot steaks with paper towels to remove excess moisture. Salt and pepper both sides of the steak. Melt 2 tablespoons butter into hot pan and immediately place steaks in to sear. Cook the meat 3-4 minutes on the first side without touching it or moving it around.
Flip your steaks over, top each steak with 1/2 tablespoon of butter and transfer to the hot oven for 5 minutes, keeping them in the same skillet.
After the 5 minutes, take them out of the oven and transfer steaks to a plate. Cover with foil and rest for 5 more minutes.
Finally, take the foil off and thinly slice the steak against the grain. Serve with vegetables, potatoes or any other side you like to have with your steak.
Serving size is for all 4 pounds of steak, that is half a pound (8 ounces) of steak per serving.
