Quick Answer
Smoking a brisket takes approximately 1–1.5 hours per pound at 225–250°F. A typical 12-pound whole packer brisket takes 12–18 hours, including the stall period. Always cook to internal temperature (200–205°F), not strictly by time.
Smoking Time by Weight (at 225–250°F)
| Brisket Weight | Estimated Time | Serves |
|---|---|---|
| 8 lbs | 8–12 hours | 6–8 |
| 10 lbs | 10–15 hours | 8–10 |
| 12 lbs | 12–18 hours | 10–12 |
| 14 lbs | 14–21 hours | 12–14 |
| 16 lbs | 16–24 hours | 14–16 |
| 18 lbs | 18–27 hours | 16–18 |
Smoking Time by Temperature
| Smoker Temp | Time Per Pound | Notes |
|---|---|---|
| 225°F | 1.25–1.5 hrs/lb | Traditional low-and-slow; most flavor |
| 250°F | 1–1.25 hrs/lb | Slightly faster, still excellent results |
| 275°F | 0.75–1 hr/lb | "Hot and fast" method; shorter stall |
| 300°F | 0.5–0.75 hrs/lb | Fastest; less smoke ring but still tender |
The Stall Explained
Around 150–170°F internal temperature, the brisket "stalls" – evaporative cooling causes the temperature to plateau for 2–6 hours. Options:
- Wait it out: Purists let it ride. Produces a crispier bark.
- Texas crutch: Wrap in butcher paper or foil at 165°F to push through the stall faster (saves 2–4 hours).
Step-by-Step Timeline
| Step | Time | Details |
|---|---|---|
| Trim and season | Night before or 1 hour ahead | Apply rub generously; refrigerate overnight for best results |
| Preheat smoker | 30 min | Stabilize at 225–250°F |
| Smoke unwrapped | 6–8 hours | Fat side up or down (debated); spritz hourly after hour 3 |
| The stall (150–170°F) | 2–6 hours | Wrap in butcher paper if desired |
| Continue cooking | 2–4 hours | Until 200–205°F internal and probe-tender |
| Rest | 1–2 hours minimum | Wrap in towels, place in cooler; allows juices to redistribute |
| Slice and serve | 15 min | Slice against the grain, ¼-inch thick |
Factors That Affect Cook Time
- Brisket grade: Choice cooks faster than Prime (less marbling).
- Wrapping: Wrapping at 165°F shortens total cook by 2–4 hours.
- Weather: Wind and cold ambient temperatures increase fuel use and cook time.
- Smoker type: Offset, pellet, and kamado smokers each have different heat retention characteristics.
- Opening the lid: Every peek adds 15–30 minutes. Minimize lid lifts.
Doneness Check
Don’t rely on time alone. The brisket is done when:
- Internal temperature reaches 200–205°F in the thickest part of the flat.
- A thermometer probe slides in with almost no resistance ("like butter").
- The meat jiggles when you shake the cutting board.
