Remove the brisket from the cooler 30 minutes before trimming to make it easier to work with. Trim the fat cap to an even 1/4 inch thickness across the entire surface, removing any hard fat or skin—this allows smoke to penetrate better and creates that coveted bark. Pat the meat completely dry with paper towels. Apply the yellow mustard as a thin, even binder across all sides of the brisket; this helps the dry rub stick to the meat and adds subtle complexity to the bark. In a small bowl, combine the salt, pepper, garlic powder, and onion powder. Generously apply the dry rub mixture to all sides of the meat, pressing gently so it adheres to the mustard layer. I like to pay special attention to the edges and crevices where the spice can concentrate for extra flavor.

Heat your smoker to 225°F using your preferred wood (oak, hickory, or mesquite all work beautifully for Texas-style brisket). Once the smoker is stabilized at temperature, place the seasoned brisket fat-side up on the grate and maintain a steady 225°F throughout. Smoke the meat undisturbed for approximately 8 hours, or until the internal temperature reaches 165°F when measured in the thickest part of the flat. This low, slow phase builds the pink smoke ring and develops that classic Texas bark. I find that maintaining consistent temperature is more important than exact timing—every smoker is different, so rely on your thermometer rather than the clock.

Once the brisket reaches 165°F internal temperature, remove it from the smoker and wrap it tightly in butcher paper or aluminum foil. This wrapping traps moisture and heat, allowing the meat to power through the stall—the plateau where the temperature rises slowly—without drying out or losing bark quality. Return the wrapped brisket to the smoker at 225°F and continue cooking until the internal temperature reaches 202°F in the thickest part of the flat, which typically takes another 5-8 hours depending on the brisket's size and your smoker's consistency. The meat should probe tender (like inserting a toothpick into butter) when fully done.

Remove the brisket from the smoker and let it rest, still wrapped, for at least 1 hour in a warm place or wrapped in towels in a cooler. This resting period allows the juices to redistribute throughout the meat, ensuring tender, juicy slices instead of dry cuts. Once rested, unwrap the brisket and slice against the grain using a sharp knife, cutting 1/4-inch thick slices. Serve immediately while still warm, and enjoy the combination of the smoky bark and tender, pink-hued interior you've worked so hard to achieve.
