  • To smoke 1.5 lb brisket, cook it for two or more hours. When 90 minutes of cooking are passed, you must test if the brisket isn’t overcooked by estimating the inner temperature.
  • The recommended time for smoking 2.5 lb brisket is approximately 4 hours.
  • 3 lb brisket, you can add more than 1 to 1.5 hours.

You can increase the smoker’s temperature up to 300 degrees or more, but this will compromise the tenderness of brisket, which you can only obtain by low and slow heating methods.

However, to skip this method, you can try the hot and fast method, where the smoker is preheated at 350 degrees to keep the meat in it. After reaching 170 degrees, you can wrap the brisket in a foil and allow more smoking till the inner temperature reaches 203 degrees. Your brisket will be juicy, tender, and flavorful at this temperature.
