Preheat oven to 375F. Place sliced potatoes on the bottom of a roasting pan. Place the lemon slices on top of the potatoes.
Whisk together the olive oil, lemon zest, broth, herbs and spices.
Pour half of the marinade over the potatoes and mix well to combine. Place the chicken on top of the potatoes and pour the remaining marinade. Sprinkle the chicken with a little freshly ground black pepper if desired.
Cover and bake for 45 minutes. Uncover and change the oven temp to 425F.
Baste the chicken and roast for an additional 40 minutes or until golden. Broil at the end if desired. Garnish with fresh parsley.
