Mix the homemade seasoning blend and rub it over the steak on all sides.
SIMPLE COOK: Preheat the grill (or cast-iron skillet) to high heat. Once the grill (or pan) is at 450-500°F, grill (or sear) the steaks for 4-6 minutes for medium-rare. Use a meat thermometer to check the internal temperature so it's between 130 and 135°F. Allow the steaks to rest for at least 5 minutes before slicing.
REVERSE SEAR: For reverse seared steaks, preheat the oven (or a smoker) to 190°F. Place the steaks in the oven (or on the smoker) for 55 minutes.
Near the end of the cooking time, preheat the grill (or a cast-iron skillet) to high heat, 450-500°F. Once hot, grill (or sear) the steaks for 1 minute per side to create caramelization.
Top each steak with a pat of butter and allow it to rest for at least 5 minutes before cutting.
