1 beef brisket roast, trimmed, about 3 to 3 1/2 pounds
2 tablespoons grill seasoning, mesquite flavored or similar
1 teaspoon smoked paprika, optional
1/4 teaspoon ground black pepper
1 tablespoon packed light brown sugar
1 cup barbecue sauce
1/2 cup water
Line a baking dish or roasting pan with foil. Heat oven to 325°.
Trim excess fat from the brisket. Combine the grill seasoning, chili powder, paprika, and pepper; rub all over the brisket. Place in the prepared baking dish and sprinkle the brown sugar over the top of the brisket. Cover the dish tightly with foil and bake for 2 1/2 hours. Slice the brisket thinly and return to the baking dish.
Combine the barbecue sauce and water and pour over the slices. Cover and continue baking for 1 hour
