Smoked tri-tip is a delicious cut of meat that comes from the bottom sirloin section of a cow. It is typically smoked in order to infuse it with flavor and give it a great texture and tenderness that is perfect for slicing or serving as-is on sandwiches.
Pat dry and season evenly all sides of the roast and lightly pat to ensure that the seasoning stays on the tri tip.
Set the smoker to 180-220° F and smoke for about 2-3 hours until you have an internal temperature between 130-135°F (medium Rare).
Remove the Tri-Tip from the smoker and increase your pellet grill temperature to 500° F.
Place a cast-iron skillet on the smoker grates, once the grill gets to temperature, add the butter to a very hot cast-iron pan (500°F) and transfer the Tri-Tip and sear for 30 seconds on each side.
Rest the tri-tip for 10 minutes before slicing against the grain and serving.
