Preparation: Start by preparing the rub. In a mixing bowl, combine brown sugar, kosher salt, black pepper, paprika, garlic powder, onion powder, dried thyme, cayenne pepper, cumin, and chili powder. Mix them thoroughly to create your flavorful rub.
Applying the Rub: Place your beef brisket on a clean surface and generously apply the rub all over the meat. Ensure every inch is well-seasoned. Use your hands to massage the rub into the meat, so it forms a delicious crust.
Resting Time: Wrap the brisket in plastic wrap and refrigerate it for at least 4 hours or overnight. This allows the flavors to meld into the meat.
Smoking Time: Preheat your smoker or grill to 225-250°F. Add wood chips or chunks for that smoky goodness. Place the brisket on the grate, and insert a meat thermometer into the thickest part. Smoke it for about 60 minutes per pound or until the internal temperature reaches 195-205°F.
Resting Again: Once done, remove the brisket and wrap it in aluminum foil. Let it rest for at least 30 minutes; this allows the juices to redistribute.
