It was our privilege one day to cook two brisket flats side by side. We applied rub to both. One received a mustard slather (see below). The other one was periodically sprayed with a thin mop sauce. There was a marked difference between the two slabs of meat at the end of the cook: The brisket that received the mustard “moisturizer” was much juicier. Do not skip the resting period once you take the brisket off the grill. Cooking times are approximate. Each brisket is different.

  • 1 brisket flat, 5 to 6 pounds, fat trimmed to 1/4-inch
  • Traeger Prime Rib Rub, or your favorite barbecue rub
  • 1/2 cup yellow or brown mustard
  • 2 tablespoons dark molasses
  • 1 tablespoon Worcestershire sauce
  • 8 to 10 strips of bacon
  • Traeger Regular BBQ Sauce or your favorite barbecue sauce


When ready to cook, start the Traeger grill on Smoke with the lid open until the fire is established (4 to 5 minutes). Season the brisket on all sides with the Traeger Prime Rib Rub. In a small bowl, combine the mustard, molasses, and Worcestershire sauce. Apply the mustard slather evenly over all surfaces of the brisket. Place the brisket, fat side down, directly on the grill grate. Drape the top with the bacon slices. Smoke for 1 hour. Increase the temperature to 225 to 250 degrees F. Continue to cook the brisket until the internal temperature reaches 165 degrees F, approximately 3 hours. Tightly wrap the brisket in a double layer of heavy-duty foil. Return to the grill and continue to cook until the internal temperature reaches 190 degrees F. Transfer the foiled brisket to an insulated container and cover it with thick clean towels (old beach towels work well) or several layers of newspapers. Allow the brisket to rest for at least 1 hour. Remove the brisket from the foil, saving any cooking juices. (If desired, you can stir some of the juices into the barbecue sauce.) Discard the bacon. Using a sharp knife, cut the brisket into 1/4-inch slices against the grain. Shingle on a warm platter and drizzle with some of the reserved cooking juices. Serve barbecue sauce on the side.
