Allow the steak to sit uncovered in the refrigerator overnight.
Season the steak liberally with steak seasoning.
Place the steak into a smoker or oven at 250°F until its internal temperature reaches 115°F, using an internal thermometer.
Sear the steak on a hot griddle or cast iron skillet until it develops a dark amber crust on the outside and its internal temperature reaches about 130°F.
Rest with compound butter if desired for at least 10 to 15 minutes.
Serve hot.
