Preheat your Traeger grill to 225°F, using a blend of hardwood pellets for maximum flavor.
Place the seasoned brisket directly on the grill grates, fat side up. Close the lid and let the smoking commence.
Maintain a consistent Traeger brisket temperature of 225°F throughout the cooking process, which can take anywhere from 8 to 12 hours, depending on the size of the brisket.
Regularly check the internal temperature of the brisket, aiming for a perfect doneness of 203°F.
Once the Traeger brisket cooking time is complete, remove the brisket from the grill and let it rest for at least 30 minutes before slicing.
