How Long to Smoke a Brisket (Per Pound, and Why Time Lies)

The single most common brisket question is also the most misleading one. People want a number, and there is a useful planning number, but if you cook brisket by the clock you will eventually serve a tough, underdone disappointment to a backyard full of people. Here is the realistic version.

The planning estimate

At a steady pit temperature of 250°F, plan on roughly 75 to 90 minutes per pound of raw, trimmed brisket. At a lower 225°F pit you can push toward 90+ minutes per pound. Some rough examples at 250°F:

• 10 lb brisket: about 12-15 hours
• 13 lb brisket: about 12-16 hours
• 16 lb brisket: about 15-20 hours

That is a wide range on purpose. Two briskets of identical weight can finish hours apart depending on fat content, your cooker, the weather, how often you open the lid, and whether you wrap. Use our Smoke Time Calculator to turn your weight and pit temp into a start time, then treat the result as a planning window, not a promise.

Why you cook to temperature, not time

Brisket is a tough cut full of collagen and connective tissue. It does not become tender at a safe temperature; it becomes tender when that collagen melts into gelatin, which happens slowly in the 195-205°F range. The USDA safe minimum for beef is 145°F with a 3-minute rest, but a brisket pulled at 145°F would be inedibly tough. You are cooking far past safe, for texture.

The real doneness test is feel. When a temperature probe or skewer slides into the thickest part of the flat with almost no resistance, it is done, usually somewhere around 203°F, but that exact number varies. See our doneness temperature chart for safe minimums versus BBQ targets across every cut.

Plan for the stall

Somewhere around 150-170°F internal, your brisket's temperature will stall and may not move for two, three, even four hours. This is normal evaporative cooling, not a broken cooker. The stall is the number-one reason briskets blow past their estimated finish time. You can ride it out or beat it by wrapping (the "Texas crutch"). We cover this in depth in The Brisket Stall.

Always finish early, then rest

Because timing is unpredictable, experienced cooks aim to have brisket done early and then hold it. A finished brisket holds beautifully wrapped in towels inside a dry cooler for 1-4 hours, and many pitmasters insist the long rest improves it. The mistake is the opposite: a brisket that is not ready when dinner is. Start early. A brisket that finishes two hours ahead is a non-problem; one that finishes two hours late is a ruined dinner.

A simple game plan

1. Weigh the trimmed brisket and estimate time with the calculator.
2. Add a 2-hour rest buffer and work backward from serving time.
3. Smoke at 225-275°F; insert a leave-in probe to watch the curve.
4. Push through or wrap during the stall.
5. Start checking for probe-tender feel around 198°F.
6. Rest wrapped in a cooler until serving.

Log the whole thing, your weight, pit temp, wrap time, finish temp, and rest, in your cook log. The second brisket is always easier than the first when you can read back exactly what happened.
