Prepare the chicken: Clean the chicken and pat it dry. If using chicken breasts cut them in half. Using a knife, cut deep slits into the chicken.
Apply wet rub: In a small bowl, mix all the wet rub ingredients together to form a paste. Smear the rub in between the slits and if there is any left over, rub it over the entire chicken breasts.
Prepare marinade: In a medium size bowl, whisk together all the marinade ingredients. Place the chicken in the bowl with marinade and mix well, making sure each chicken breasts is fully coated.
Marinate chicken: Cover the bowl with plastic wrap and refrigerate for a couple hours.
Preheat oven and baking sheet: Preheat your oven to 400 F degrees. Line a baking sheet with aluminum foil and over it, place a grill rack.
Place the chicken breasts over the grill rack leaving a bit of space in between each piece.
Bake: Bake the chicken for 30 minutes. 15 minutes in, brush some butter over each piece. After the first 30 minutes, turn the chicken pieces over, brush with more butter and bake for another 15 minutes.
Garnish with lemon slices, parsley and serve.
