Start by mixing the brine ingredients: kosher salt, brown sugar, cold water, and cold chicken broth. Stir until the salt and sugar dissolve completely.

Next, place the turkey breast into a large ziplock bag and pour the brine over it. Seal the bag and set it in a bowl to keep it upright. Let the turkey soak in the brine for 4 to 12 hours for the best flavor.

When you're ready to cook, preheat your oven to 425°F.

Take the turkey out of the brine, rinse it under cold water, and pat it dry with paper towels. Place it in a 9x13-inch baking dish. To help support the turkey, make four balls of foil—put two on either side, one under the tip, and one nestled near the rib cage.

Carefully separate the skin from the turkey breast and spread the softened butter underneath. Drizzle olive oil on top and season with the remaining salt and black pepper.

Roast the turkey in the oven for 30 minutes. Then, reduce the temperature to 325°F and continue roasting until it reaches an internal temperature of 160-165°F, which should take about 45 minutes to an hour longer.

Once done, let the turkey rest for at least 15 minutes before slicing. Enjoy this juicy turkey that's perfect for any occasion!
