Preheat the oven to 350˚F.
In a small mixing bowl, put together softened unsalted butter, oregano, thyme, garlic powder, and onion powder. Using a fork, mix it all together until the seasoning is evenly distributed.
NOTE: For thyme and oregano, you can use either dried or fresh leaves. If you are using fresh leaves, just finely chop them before adding to the butter.
Then when the turkey breast is defrosted, rinse and pat dry the meat.
Rub salt evenly all over the turkey.
Using the back of a spoon of fingers, carefully lift the skin from the turkey breast and spread ½ of the butter mixture inside. Use the rest of the butter/herb mixture and spread it on top of the skin, the sides, and the bottom of the meat.
Place the turkey in a baking pan with skin side up.
Place the baking pan with turkey in the oven and bake for about 90-100 minutes or until the internal temperature reaches 165˚F.
NOTE: I like to rotate the pan and pour the pan juices over the turkey a few times while the turkey is cooking. That will help the meat to cook evenly and stay juicy.
