How long do you cook a 8lb brisket?

The cooking time for an 8lb brisket can vary depending on the cooking method and the desired doneness. Here are a few general guidelines:

Smoking: Smoking an 8lb brisket typically takes between 8 to 12 hours. The brisket is cooked at a low temperature (around 225°F) until it reaches an internal temperature of 200°F to 205°F for sliced brisket, or 195°F for pulled brisket.

Braising: Braising an 8lb brisket in liquid (such as beef broth or water) usually takes 3 to 4 hours. The brisket is cooked at a simmer until it becomes fork-tender and reaches an internal temperature of 200°F to 205°F.

Roasting: Roasting an 8lb brisket in the oven can take anywhere from 4 to 6 hours. The brisket is cooked at a moderate temperature (around 325°F) until it reaches an internal temperature of 200°F to 205°F.

It's important to note that these are approximate cooking times and the actual time may vary depending on the specific cooking conditions, such as the type of smoker or oven used, as well as the desired level of doneness. To ensure the brisket is cooked properly and safely, it's recommended to use a meat thermometer to monitor the internal temperature.
