Place steak directly on smoker and smoke for 20 minutes at 180°F. After 20 minutes, remove from the smoker and put on plate. Tent with aluminum foil.
Place grill grates on smoker and increase temperature to 450°F. Once heated, place steak on grill grates and cook until desired internal temperature, test with thermometer. Always cook to temperature and not time. However, It should take about 6-9 minutes a side for medium.
When steak reaches desired temperature, remove from smoker and allow to rest 10 minutes before slicing.
Notes
Add butter to the top of the steak after cooking and allow to melt, this will give the smoked steak a really good flavor.
Sear over open flame to get the best crust on the steak. I love a good char on my steak.
Pull the steak from the grill 5°F before your desired internal temperature, it will finish cooking while it rests.
