Preheat your smoker to 225°F using oak or hickory wood for an authentic Texas flavor profile.
Trim the beef brisket of excess hard fat, leaving a thin layer for moisture, and pat the surface completely dry.
In a small bowl, combine the sea salt, cracked black pepper, and garlic powder to create a simple dry rub.
Apply the rub generously to all sides of the brisket, pressing it into the meat to ensure a thick crust forms.
Place the brisket in the smoker and cook until the internal temperature reaches 165°F, then wrap tightly in butcher paper.
Continue smoking until the internal temperature reaches 203°F and the meat feels tender when probed.
While the meat rests, toss cubed sweet potatoes with olive oil and roast at 400°F for 20 minutes until caramelized.
Steam the green beans for 5-7 minutes until bright green and crisp-tender, then toss with apple cider vinegar.
Allow the brisket to rest for at least 30 minutes before slicing thinly against the grain to serve.
