First, remove the turkey breast from the fridge and leave it out for about 30 minutes before cooking. Adjust the oven rack to the lower middle position, and preheat oven to 400°F.
In a small bowl, add butter, salt, black pepper, garlic, thyme, parsley and rosemary. Mix all together. Set aside.
Use an upside spoon to help loosen the skin from the turkey flesh, if necessary.
Using your hands, add some butter mixture under the skin, then add some on the top of the breast. Spread butter mixture as evenly as possible. Then, sprinkle some more salt and pepper over the turkey breast.
Turn turkey upside down and spread more butter mixture on it. Then, if you have any butter mixture leftover, add on the baking pan.
Place turkey in baking pan, skin side up. Place turkey in the oven and turn the temperature down to 350F.
Roast for 1 hr 30 minutes (the time will depend on the size of your turkey breast) and don’t forget to bast all over the turkey breast every 30 minutes. When the turkey is done the internal temperature should be 165F.
If your turkey gets brown so quickly, cover it with foil to avoid burning outside.
Rest for 15 minutes before cutting and serving. Use the melted butter mixture as gravy. So yummy!
