Brisket Cook Time Calculator

Brisket Cook Time depends primarily on the weight of the meat, the cooking temperature, and the cooking method. Brisket is a tough cut from the chest of a cow that requires low and slow cooking to break down the collagen and become tender.

General Rule of Thumb:

• Smoking (225°F / 107°C): approximately 1 to 1.5 hours per pound (2.2 to 3.3 hours per kg)
• Smoking (250°F / 121°C): approximately 0.75 to 1.25 hours per pound (1.7 to 2.75 hours per kg)
• Oven braising (300°F / 149°C): approximately 0.5 to 0.75 hours per pound (1.1 to 1.7 hours per kg)
• Hot and fast (325°F / 163°C): approximately 0.4 to 0.6 hours per pound (0.9 to 1.3 hours per kg)

The Stall: Brisket experiences a temperature stall around 150 to 170°F (66 to 77°C) internal temperature. During the stall, evaporative cooling on the meat surface balances the heat input, and the internal temperature can plateau for hours. This can add 2 to 4 hours to your cook. Wrapping the brisket in butcher paper or foil (the “Texas Crutch”) helps push through the stall faster.

Target Internal Temperature: Brisket is done when it reaches an internal temperature of 195 to 205°F (90 to 96°C). At this temperature, the collagen has fully rendered into gelatin, making the meat tender and juicy. Always use a meat thermometer — time is a guide, but temperature is the truth.

Rest Time: After cooking, brisket should rest for at least 30 minutes to 1 hour. Many competition pitmasters rest briskets for 2 to 4 hours wrapped in a cooler. Resting allows the juices to redistribute throughout the meat. A 12-pound (5.4 kg) brisket smoked at 225°F might take 12 to 18 hours to cook, plus 1 to 2 hours of rest.

Weight Considerations: A full packer brisket typically weighs 12 to 18 pounds (5.4 to 8.2 kg) and includes both the flat and the point. A flat-only cut is usually 6 to 10 pounds (2.7 to 4.5 kg). Plan about half a pound (225 g) of raw brisket per person to account for shrinkage during cooking.
