In a saucepan, add salt, oregano, peppercorns and sage leaves, and enough filtered water to dissolve the salt. Turn the heat to medium and stir with a wooden spoon until all the salt has dissolved. You should not be able to hear any scrapings of grit at the bottom of the pan. There is no need to bring the mixture to a boil.
1 cup Kosher salt, water, 1 tablespoon oregano, 1 tablespoon peppercorns, 8 leaves sage
Take the brining mixture off the heat and let it come to room temperature. I usually transfer brining mixture to a big glass measuring container and place it in the fridge for 10 minutes.
Open the package of thawed turkey breast, remove giblets if included, and pat the turkey down with paper towels.
5 pound turkey breast
Place turkey in a big stockpot and pour cooled brining mixture over the turkey. Add enough filtered water to cover the turkey and place in the refrigerator for 8 - 24 hours. I like it to be in the brining solution for at least 18 hours.
Preheat oven to 325 F.
Slice onion into thick slices and place in the bottom of a roasting pan.
1 medium onion
Remove turkey from the brining solution and set aside. Dump the solution down the drain. Rinse turkey inside and out and pat dry with paper towels.
Lay turkey breast side up on the onions and add two sprigs of rosemary and 4 sage leaves to the pan. Rub the butter and garlic paste on the skin and sprinkle pepper on the bird. If you don't have garlic paste, sprinkle garlic powder on the bird.
1 tablespoon butter, 2 teaspoons garlic paste, 2 sprigs rosemary, 4 leaves sage, 1/4 teaspoon ground pepper
Bake - between 15 - 20 minutes per pound. My 5-pound turkey breast took 1 hour and 40 minutes. Check the temperature in the thickest part of the breast. The temperature should be between 155 - 160 F. (The temperature will rise somewhat as the turkey rests).
Let the turkey rest for 20 minutes before cutting it in slices.
