Once the brisket is trimmed, this includes trimming the fat cap to about 1/4 inch thick, season the brisket with the Head Country seasoning and brown sugar on all sides. It's best to use a sheet pan that has sides to hold it in.
Place this on the sheet pan and let the brisket rest in the fridge for 24 hours.
Warm up the pellet grill to 250°F.
Place the brisket fat side down directly on the grill grates and cook until the internal temperature reaches 170°F, this can take anywhere from 6-8 hours depending on the size of the brisket.
After it has reached 170°F, carefully remove and wrap the brisket in aluminum foil or butcher paper. Place back on the pellet grill for an additional 3-4 hours until the internal temperature reaches near 205°F.
This process will take about 10-12 hours for a 10-pound brisket.
Once fully cooked, remove and let the brisket rest for at least 1 full hour.
Slice or Chop and Serve with barbecue sauce.
Notes
Add barbecue sauce during cooking time if you prefer.Be sure to follow the instructions of your specific smoker when it comes to setup and adding the wood chips etc.The cooking time will also vary depending on outdoor temperature as well as the size of the brisket, so be sure to use a meat thermometer to be sure that it's fully cooked internally. It is typically based on 1-1 1/2 hours per 1 pound of meat.
