Preheat Traeger Grills or Pitt Boss or whatever pellet grill you’re using to 225 degrees F.
Prep flank steak for smoking by first preparing the marinate. Combine all marinade ingredients into a bowl and stir until combined.
Add flank steak to the marinade and place the bowl into the fridge for at least 30 minutes.
Smoke flank steak for about 90 minutes directly on the grill grates of your smoker, keeping in mind your desired internal temperature. (Exactly how long to smoke flank steak at 225 degrees F will depend on how thick it is, and how many times the smoker was opened, letting heat escape.)
Remove flank steak. I recommend pulling the steak off at 130 - 135 degrees F internal temperature for a medium-rare finish. For more of a medium smoked flank steak, pull it from the smoker when the temperature reaches 140 - 145 degrees F as measured with an internal read thermometer.
Finish smoked flank steak by slicing into strips or into smaller pieces if making marinated flank steak tacos and enjoy.
