Unwrap the steaks, place them on a plate, and leave uncovered in the refrigerator for 1–2 hours.
When you are ready to cook, preheat your oven to 450 degrees F.
Place a 12-inch cast iron skillet on the stove over medium-high heat and heat until very hot.
Remove the steaks from the refrigerator and season both sides with kosher salt and black pepper to taste.
Carefully add the steaks to the hot skillet and do not move them. Sear until you see a color change about halfway up the sides, about 5 minutes.
Flip the steaks, then immediately transfer the skillet to the preheated oven.
Cook in the oven 8–10 minutes, or until an instant-read thermometer inserted into the thickest part reads 120–125 degrees F.
Remove the steaks from the oven and transfer to a plate or cutting board. Let rest until the internal temperature reaches 130–135 degrees F.
Serve plain.
Notes
125 degrees is the internal temp for a rare steak.
135 degrees is the internal temp for a medium rare steak.
145 degrees is the internal temp for a medium steak.
