Preheat the oven to 340 F. Place garlic, dried herbs and olive oil in a saucepan. Bring to a boil and cook the garlic in the oil over very low heat for about 20 minutes. This way the garlic will give all its flavor to the oil, but cloves will become fried, so you will need to throw those away when done.
Allow garlic infused oil to cool for at least 30 minutes.
Rub the turkey breast on all sides with salt and pepper. Place the turkey in a roasting pan and pour the cooled garlic oil over it.
Cover the baking dish with foil or a lid. Bake for 40 minutes, then another 20 minutes without foil. Slice and serve.
