Remove the steak from the refrigerator. Salt it generously on both sides. Then, let it rest at room temperature for 30-45 minutes before cooking.
Preheat your skillet with oil to high heat.
Season the steak with black pepper on both sides before transferring it to the skillet.
Sear the steak for 2-3 minutes or until golden brown on the bottom side.
Flip the steak to the other side to sear for another 2-3 minutes.
Add the butter to the pan, allowing it to melt completely. Reduce the heat to low to continue letting the steak cook for another 3-5 minutes, or until it reaches 125-130℉, spooning the butter over the top consistently.
Move the steak to a clean plate tented with foil to rest for 10 minutes before serving.
