Combine Traeger Sweet & Heat BBQ Sauce into a shallow casserole dish and stir to combine.
Place the strip steak in the mixture, making sure the steak is coated evenly on both sides. Cover with plastic wrap and marinate in the refrigerator for a minimum of 3 hours to overnight.
Remove the steak from the marinade and season with Traeger Beef Rub. Let steaks come to room temperature before grilling, about 45 minutes.
When ready to cook, set the Traeger to 500℉ and preheat, lid closed for 15 minutes.
Place steak toward the front of the grill grate and cook for 4-5 minutes on each side until steaks reach desired internal temperature, 130℉ for medium-rare.
Remove from the grill and let rest for 5 minutes. Slice against the grain to serve. Enjoy! *Cook times will vary depending on set and ambient temperatures.
