A whole packer brisket, 16 to 20 lbs, Prime grade, SPG rub, injected and smoked overnight on the Traeger at 225°F with Super Smoke mode. Wrapped at 165°F with rendered fat from the trimmings. Pulled probe-tender between 200 and 203°F. Rested two hours minimum. This is the cook.
Brisket is not a forgiving cut. What you start with determines most of what you end up with.
Look for a whole packer in the 16 to 20 lb range with consistent thickness from flat to point. Bigger briskets take forever and are harder to manage. Smaller ones dry out too quickly. Consistent thickness means the flat and point cook more evenly.
Prime grade or better. Costco is a reliable, consistent source. A high-quality local butcher is great too. Look for good marbling throughout the flat — that's what keeps it moist over 16+ hours. Limit black deckle fat on the point.
Do not separate the flat from the point to smoke them separately. It's unnecessary work and you cut out too much good meat in the process. Cook it as a whole packer, start to finish.
The minimalist trim. Square up the edges so the brisket cooks evenly. Remove only the hardest, most excessive chunks of fat — the ones that are clearly too thick to render during the cook. Leave a solid fat cap. Fat equals flavor and it protects the meat over a 16+ hour cook.
T-Bone’s Pro Tip: Do not throw away those fat trimmings. Every chunk of fat you cut off goes into a foil pan. That pan goes on the smoker alongside the brisket overnight and renders into pure beef fat — smoke-flavored, rich, and ready to go into the wrap.
Inject and rub. Mix the brisket injection dust with 1–2 cups of warm water. Working in a grid pattern, inject the entire flat and point thoroughly — you want coverage across the whole cut, not just in one area. Then coat every surface of the brisket with the SPG rub. A big cut like this needs a heavy coat to build bark over 16+ hours. Be generous.
The overnight smoke. Set the Traeger to 225°F and activate Super Smoke mode. Around 10:00 PM, place the brisket on the grates and set the foil pan of fat trimmings alongside it. Close the lid. Go to sleep. The Traeger holds temperature through the night — you don’t need to monitor it. This is the whole point of the Traeger for a cook like this.
The morning wrap and the liquid gold. Around 7:00–8:00 AM, check the internal temperature. You’re looking for 160–165°F with a deep, dark bark that’s firmly set on the surface. Pull the brisket off the smoker.
Take the foil pan of rendered beef fat and pour approximately ½ cup directly over the brisket. That rendered fat is carrying 8+ hours of smoke flavor. It’s going to baste the brisket from the inside of the wrap for the rest of the cook.
Wrap tight in unwaxed butcher paper (crustier, firmer bark) or double-wrap in heavy-duty foil (softer bark, slightly faster). Return to the smoker. You can raise the temperature to 250°F at this point to speed up the finish if needed.
Cook to probe-tender. Continue cooking until the internal temperature of the flat reads 200–203°F. Then do the probe test: insert your thermometer probe into the thickest part of the flat. It should slide in and out with zero resistance — like pushing into warm butter. No resistance means it’s done. Any stiffness means it needs more time, regardless of what the temperature says.
Protect the flat if needed. Between 185°F and 203°F, keep a close eye on the flat. The flat is thinner and will always finish before the point. If it’s looking like it’s drying out, cover just the flat with a small piece of foil while the point continues. The point needs more time; the flat doesn’t.
The mandatory rest. Pull the wrapped brisket off the smoker. Do not skip this. The rest is not optional — it is part of the cook.
Option A — Oven hold: Place the wrapped brisket in an oven set to 160°F. It will hold there for hours.
Option B — Faux Cambro: Place the wrapped brisket in a dry empty cooler and pack towels tightly around it. The insulation keeps the temperature up. Rest a minimum of 2 hours.
Please do not squeeze the juices out of your brisket for a photo shoot. The brisket gods might curse you for years to come with dry brisket — and no one wants that.
Slice and serve. Slice against the grain. On the flat the grain runs in one consistent direction — straightforward. On the point the grain changes direction, so rotate as you go. Target thickness is about ¼ inch. Serve immediately. Keep the flat and point separated on the board so people can pick their preference — the point is fattier and richer, the flat is leaner and slices cleaner.
