Determining “how long to cook brisket” is critical for achieving a tender and flavorful result. Brisket, a cut of beef from the breast or lower chest, requires a low and slow cooking method to break down its tough connective tissues.
The optimal cooking time varies depending on the size and thickness of the brisket, as well as the desired level of tenderness. Generally, a 3- to 4-pound brisket will require 8 to 12 hours of cooking at a temperature of 225 to 250 degrees Fahrenheit (107 to 121 degrees Celsius).
