Clean the turkey by rinsing it and removing the neck and giblets. Pat the turkey dry.

Combine the vegetable stock and sea salt in a large stock pot over medium heat.

Bring the stock and sea salt to a boil and continue stirring.

Add in the poultry seasoning, sage, thyme, and rosemary.

Bring everything to a boil and stir occasionally.

Once the salt has dissolved, take the stock pot off the burner and let the mixture cool to room temperature.

Once the brining liquid has cooled to room temperature, add the liquid to the gallon of ice water in a large bucket or ziplock bag.

Submerge the turkey and seal up the bag or bucket. Place the brining turkey in the fridge or other cold place. Allow the turkey to brine for 24–48 hours.

Preheat the grill for 10–15 minutes on high heat to 500–550 degrees Fahrenheit.

While you are preheating the grill, rinse the brine and pat the turkey dry. Lightly brush the turkey with vegetable oil.

Place the turkey in a foil or roast pan, and turn down the grill to medium heat and keep the temperature around 400 degrees. The turkey will take 2–3 hours to cook. It is roughly 11–13 minutes per pound.

Baste the turkey every 20–25 minutes until the internal thigh temperature is 170 degrees. The breast should be 165 degrees. Take the turkey off the grill and set aside covered in foil. The internal temperature of the turkey should be around 180 degrees in the thigh.
