How long to smoke a brisket?
Plan on roughly 1 to 1.5 hours per pound at 225–250°F, then at least an hour of rest. At 250°F a 14-pound packer is usually 14–18 hours of cook time before the rest. Cook to probe tenderness (most finish around 195–205°F), not to the clock.
- Pit temperature
- 225–275°F
- Estimated time
- ≈1–1.5 h per lb at 225–250°F; faster at 275°F
- Done when
- Probe-tender, usually ~195–205°F
- USDA safe minimum
- 145°F + 3-minute rest (whole beef cuts)
- Wrap
- Optional — most cooks wrap in butcher paper or foil around 160–175°F, once the bark is set and the color is where you want it.
- Rest
- At least 1 hour; a well-wrapped brisket held warm (around 150–170°F in an oven or insulated cooler) can rest several hours.
Brisket smoking time by pit temperature
| Pit temperature | Estimated cook time |
|---|---|
| 225°F | 1.25–1.5 h per lb |
| 250°F | 1–1.25 h per lb |
| 275°F | 0.75–1 h per lb |
Estimates for planning only. Every cut, cooker and day is different — cook to temperature and tenderness, not the clock.
Planning table by weight
| Weight | 225°F | 250°F | 275°F |
|---|---|---|---|
| 8 lb | 10–12 h | 8–10 h | 6–8 h |
| 10 lb | 13–15 h | 10–13 h | 8–10 h |
| 12 lb | 15–18 h | 12–15 h | 9–12 h |
| 14 lb | 18–21 h | 14–18 h | 11–14 h |
| 16 lb | 20–24 h | 16–20 h | 12–16 h |
Cook time only — add rest time and a buffer. The serve-time planner works backward from dinner for you.
What changes the cook time
- The stall. Between about 150°F and 170°F evaporation can flatten the temperature curve for hours. Wrapping shortens it.
- Thickness beats weight. A thick, compact packer takes longer than a long, flat one of the same weight.
- Pit stability. Every lid-open and every temperature swing adds time. Offsets in wind and cold run long.
- Grade and fat. Higher-marbled briskets often probe tender a little sooner and are more forgiving.
The Major's orders, step by step
- Work backward from serving time: cook-time estimate + 2 hours rest + a 2–3 hour buffer. Start earlier than feels necessary — a brisket that finishes early holds beautifully; one that finishes late does not.
- Run the pit at 225–275°F with clean smoke. Spritz sparingly, if at all.
- Wrap (optional) when the bark is set and dark, typically around 160–175°F.
- Start probing around 195°F. Done is when the probe slides into the flat like soft butter in several places.
- Rest wrapped, then slice the flat across the grain about pencil-thick.
Which wood for brisket?
Post oak. It is mild, clean and dense enough to hold a steady fire for a 12-plus-hour cook, so the beef stays the headline and the smoke plays support. Pecan is the best alternative; a little cherry adds color.
Best wood for smoking brisket →Questions recruits ask
How long does a 12 lb brisket take to smoke?
At 250°F, plan roughly 12–15 hours of cook time, plus at least an hour of rest. At 225°F it can run 15–18 hours. Leave a buffer — briskets vary.
Is it better to smoke brisket at 225 or 250?
Both work. 250°F shortens the cook with little downside for most backyard cooks; 225°F gives more margin for error on fire management. Consistency matters more than the exact number.
Can you rest a brisket too long?
Not if it stays hot. Hold it wrapped above 140°F (most cooks hold around 150–170°F). Below 140°F for long periods is a food-safety problem.
