Wash your turkey and pat dry with paper towel before you take out all the innards. You can choose to discard the innards or keep them for use in your stuffing, known as giblets.
Combine the vegetable broth, seat salt, pepper, thyme, savory, rosemary, and water in a large pot and bring to a boil.
Once you're sure the salt has dissolved, remove the pot from heat and let cool to room temperature.
Place the turkey breast down in the brine using a deep dish pan so it saturates it inside and out. Let it sit refrigerated overnight to marinade (24 hours).
You may also choose to use a brine bag: place the double bag, mouth open wide and facing up, in the roasting pan. Fold back the top one-third of the double bag to help keep the bags open). Place the turkey inside the double bag and pour the room temperature brine over the bird. Now you may marinade for 24 hours.
Before you cook the turkey, drain off some of the excess brine.
Preheat your oven (the temperature depends on the weight of the turkey. If your turkey is roughly 10 pounds, preheat your oven to 325 degrees and expect to cook it for at least 3 hours).
Check your turkey every hour to avoid overcooking as brining tends to reduce cooking time.
Cook for a minimum of 3 hours, then remove and let sit for 10 minutes before carving.
