Brisket Cook Time Calculator
Smoking a brisket is an all-day project, and the hardest part is timing it to land when you want to serve. This calculator multiplies your brisket weight by the cook hours per pound from your method, adds an optional buffer for the stall, and adds your planned rest, returning a total time from smoker-on to slicing. Because smoker temperature, wrapping and the stall all vary, hours per pound is a user-editable input. The brisket is finished by probe tenderness, not the clock, and food safety follows FSIS handling guidance for whole beef.
Brisket time formula
cook time (h) = weight (lb) * hours per pound + stall buffer
cook time (min) = cook time (h) * 60
total time (h) = cook time + rest
total time (min) = total time (h) * 60
Start early and let the probe decide doneness. The buffer absorbs the unpredictable stall so you are not late.
Brisket cook notes
- Low and slow runs roughly 1 to 1.5 hours per pound at 225 to 250 deg F.
- FSIS safe whole-beef temperature is 145 deg F with a 3 minute rest; tenderness comes much higher.
- Pitmasters often pull brisket near 200 to 205 deg F for probe tenderness.
- The stall around 150 to 170 deg F can add hours; wrapping speeds it.
- Hold wrapped and rested for 1 to 4 hours before slicing.
Brisket cook time: frequently asked questions
How long does brisket take to smoke?
A common low-and-slow estimate is about 1 to 1.5 hours per pound at 225 to 250 deg F, so a 12 pound brisket can run 12 to 18 hours. Because the stall, smoker temperature, wrapping and the cut all vary, hours per pound is a user-editable input. The brisket is done by probe tenderness and internal temperature, not by the clock.
What internal temperature is brisket done at?
Food safety is reached well before tenderness. USDA FSIS lists 145 deg F with a 3 minute rest as safe for whole beef. Pitmasters typically pull brisket much higher, around 200 to 205 deg F, because the collagen needs prolonged heat to render and probe tender. Safety and tenderness are different targets.
Why add a resting time?
Brisket benefits from a long rest, often held wrapped in a cooler for 1 to 4 hours. Resting relaxes the muscle, reabsorbs juices and makes slicing cleaner. This calculator adds your chosen rest to the cook estimate so you can back-time from when you want to serve.
What is the stall?
The stall is a period where the internal temperature plateaus for hours, around 150 to 170 deg F, as surface moisture evaporates and cools the meat. Wrapping in foil or butcher paper (the Texas crutch) pushes through it faster. Because the stall length is unpredictable, build in buffer time and rely on the probe.
How do I plan a finish-by time?
Enter the cook hours per pound, weight, and rest, then start early. This tool gives total time from smoker-on to serving so you can count backward from your meal time. Experienced cooks add a one to two hour buffer because the stall can extend the cook unexpectedly.
