Preheat smoker or pellet grill to 225°F. Place steaks on.
Smoke until internal temperature is about 20°F under desired finish temperature.
When the internal temp get close to 20°F under your desired temp, start your Sidekick Sear and place on medium to high heat.
Place each steak on the BBQ Box for about 30-60 seconds. Rotate about 45° to get diamond sear marks and sear for another 30-60 seconds.
Then turn the steaks and repeat the process. Use a meat probe thermometer to sear to the desired temperature.
