Preheat your oven to 425°F. Take your turkey breast and pat it dry using a paper towel. Place in a roasting pan.
Zest the lemon, and set aside. Mince up 2 sprigs of rosemary and 2 sprigs of thyme.
Mix softened butter, lemon zest, garlic, and minced rosemary and thyme.
Run your fingers under the skin of the turkey breast to loosen it up slightly. Rub half of the butter mixture under the skin of the turkey breast.
Take the remaining butter mixture and rub it on the outside of the turkey breast. You can also season the turkey with additional salt and pepper if you wish.
Pour chicken stock in the bottom of the roasting pan, and squeeze the lemon juice from the leftover lemon into the pan. Add remaining herbs.
Roast the turkey breast at 425°F for 30 minutes until golden brown.
After 30 mins, turn the oven temperature down to 325°F and roast for about 1-1.5 hrs or until turkey breast reaches 165°F.
Once turkey is done, let rest for 15-20 minutes, then slice and serve!
