Preheat the oven to 425° F.
Line a baking sheet with foil. Alternatively, you can use a cast iron skillet, which does not need to be lined.
Thinly slice the lemon. Mix together the spices, salt, and pepper in a small bowl. Set the lemon slices and spice mixture aside.
Pat the chicken dry on all sides with a paper towel, then place it on the baking sheet or in the cast iron skillet with the skins facing up. Give each piece of chicken plenty of space so that the skins can brown.
Coat the chicken with olive oil and then rub the spice mixture on all sides. Brush butter on the top of each piece.
Place one lemon slice underneath each piece of chicken. Then place the rest of the lemon slices on top of the chicken pieces or in any nook or cranny you can find.
Bake the chicken for 30 to 35 minutes or until the internal temperature reaches 165° F, turning the pan halfway through for even browning.
