Brisket Cook Time 225 / 250 / 275°F

Honest time ranges for planning the day — then a thermometer, not the clock, decides when it's done. Pull window: 200–205°F.

⏱️ Worked example: to serve at 6:00 pm, a 13-lb packer brisket at 250°F (16¼–22¾ hr) plus rest and a cushion means meat on around 4:15 pm the day before, smoker lit ~40 minutes earlier. The cook time planner runs this for your own serve time.

Doneness: 200–205°F

Pull when a probe slides in like warm butter, usually 200–205°F in the flat. Feel beats the number.

🌡️ Food safety: Whole-muscle beef is safe at 145°F with a 3-minute rest — but safe is not the same as tender.

Wrapping

Wrap in butcher paper (or foil for a softer bark) once the bark is set and the internal temperature stalls around 165–175°F — usually the middle third of the cook.

Rest & hold

Rest at least 60–120 minutes. Wrapped in a towel-lined dry cooler, a brisket holds above 140°F for 4+ hours — a long hold is a planning superpower, not a compromise. For food safety, hold hot meat above 140°F — a wrapped rest in a dry cooler does exactly that.

How much to buy

Quantities are the other half of the plan: portions, yield, and a group-size chart live on how much brisket per person.

Frequently asked questions

How long does brisket take to smoke at 225°F?

Plan 1.5–2 hours per pound at 225°F — a typical 13-lb packer brisket runs 19½–26 hr. That's a planning range, not a promise: shape, fat, and the stall all move the finish.

What temperature is brisket done?

Pull when a probe slides in like warm butter, usually 200–205°F in the flat. Feel beats the number. Whole-muscle beef is safe at 145°F with a 3-minute rest — but safe is not the same as tender.

Should I wrap brisket?

Wrap in butcher paper (or foil for a softer bark) once the bark is set and the internal temperature stalls around 165–175°F — usually the middle third of the cook.

How long should brisket rest?

At least 60–120 minutes. Wrapped in a towel-lined dry cooler, a brisket holds above 140°F for 4+ hours — a long hold is a planning superpower, not a compromise.
