Place lemon juice, lemon zest, olive oil, garlic, thyme, rosemary, salt, and pepper in a small bowl. Whisk to combine. With the tip of a sharp knife, make a shallow cut into each of the chicken 2 or 3 times, about half inch long.
Bake for 30 minutes, or until internal temperature has reached 165°. When done, remove the baking dish from the oven and discard the additional liquid.
Melt the butter and baste it on top of each piece. Allow to rest for about 5 minutes prior to serving. Garnish with fresh lemon or lime slices, if desired. Enjoy!
