Another option is to put a griddle (or GrillGrates) on the pellet smoker when it's cranked to high heat, get it blistering-hot, add just a little oil to prevent sticking, and sear by conduction on the metal. It should take only two to three minutes per side. This is a good technique for reverse-seared meats: You start them indirect, low and slow on the cooking grate, with a little smoke, and then sear the surface with direct contact to the hot metal griddle to create a delicious brown crust. It's not as good as searing directly over hot coals or gas, but it's a good compromise.
Pellet grills preheat quickly, so you can start cooking almost immediately, and the pellets are available in a number of woods, for different smoke flavors. The smoke has a subtle wood-fired flavor with less of the acrid flavor that comes from standard wood or charcoal. For the maximum smoke flavor, it’s best to cook at a temperature lower than 250 degrees, while higher temperatures cook faster with less smoke.
