01 - In a large bowl, whisk together buttermilk, olive oil, garlic, salt, pepper, smoked paprika, thyme, oregano, cayenne pepper, and lemon zest until fully combined.
02 - Add the chicken pieces to the marinade, turning to coat each piece thoroughly. Cover the bowl and refrigerate for at least 8 hours or overnight for maximum flavor penetration.
03 - Preheat oven to 425°F. Line a large baking sheet with parchment paper or foil and place a wire rack on top.
04 - Remove chicken from the marinade, allowing excess to drip off. Arrange pieces skin-side up on the wire rack. Discard the used marinade.
05 - Brush the chicken lightly with olive oil and sprinkle with additional freshly ground black pepper.
06 - Roast for 40–45 minutes until chicken is golden brown and juices run clear. Internal temperature should reach 165°F when tested with a meat thermometer.
07 - Let the chicken rest for 5 minutes before serving. Garnish with chopped fresh parsley and serve with lemon wedges on the side.
