Cover the steak with kosher salt and let it set for about two to three hours, preferably overnight in the fridge.
After brining, coat the steak with your chosen barbecue rub, ensuring thorough coverage on all sides.
Set the Ninja Woodfire Grill to smoker setting at 275°F for cooking the steak indirectly.
Smoke the steak until it reaches an internal temperature of about 125°F (rare).
Increase grill temperature to high and sear the steak for about a minute on each side.
Let the steak rest for at least 15 minutes before slicing to allow juices to redistribute.
