Instructions
Remove the steaks from the refrigerator 15 minutes before cooking. Pat the steaks dry with a paper towel and then lightly cover with oil.
If your making your own rub mix the spices and seasonings in a bowl. Liberally coat every side of the oiled steaks.
Load the pellets, prime, set the grill temperature to 225°F, and wait until up to temp. Place the steak directly on the grill grate, insert the temperature probes and monitor until your required doneness.Then cook the sirloin for around an hour. You want to remove the steak from the smoker once it is within 10°F of your target temperature. I have put the target temperatures for all types of doneness below.
When the steaks are 10°F from your target remove them from the grill and increase the temperature of the Trager to 450°F. You can also do this step in a cast iron pan on the stove as well. Once your Traeger or cast iron pan has reached the correct temperature sear your steaks for 1-2 minutes per side.You want to get a brown crust that is full of flavor. Once you have seared both sides remove the steak and allow it rest for 5-7 minutes.

If you want to be extra indulgent, melted 2-3 tablespoons of butter with a sprig of rosemary over low heat. You can now slice the sirloin steak against the grain and serve. Then drizzle it the melted butter over the steak.
