01 - Combine cold water, kosher salt, and sugar in a large mixing bowl. Stir until the salt and sugar are fully dissolved.
02 - Submerge the chicken or turkey breast in the brine, cover the bowl, and refrigerate for 4 to 8 hours.
03 - Preheat oven to 325°F.
04 - Remove the meat from the brine and pat thoroughly dry with paper towels. Combine black pepper, garlic powder, onion powder, smoked paprika, and dried thyme, then sprinkle the seasoning blend evenly over the meat and rub gently to adhere.
05 - Roll the seasoned meat tightly in parchment paper, then wrap securely in aluminum foil, twisting both ends firmly to form a compact log.
06 - Place the wrapped meat log on a wire rack set over a rimmed baking sheet.
07 - Roast for 1 hour, or until a meat thermometer inserted into the thickest part registers an internal temperature of 162°F.
08 - Remove from the oven and let cool completely, preferably refrigerated overnight. Slice thinly for sandwiches, salads, or charcuterie boards.
