01 - In a large bowl, whisk together buttermilk, olive oil, garlic, salt, pepper, smoked paprika, thyme, oregano, cayenne (if using), and lemon zest until well combined.
02 - Add the chicken pieces to the marinade, ensuring each piece is well coated. Cover and refrigerate for at least 8 hours or overnight for best flavor.
03 - Preheat your oven to 425°F. Line a large baking sheet with parchment paper or foil and set a wire rack on top.
04 - Remove the chicken from the marinade, letting excess drip off. Arrange the pieces, skin-side up, on the rack. Discard the used marinade.
05 - Brush chicken lightly with olive oil and sprinkle with extra black pepper.
06 - Roast for 40–45 minutes, or until the chicken is golden brown and juices run clear (internal temperature should reach 165°F).
07 - Let rest for 5 minutes. Garnish with parsley and serve with lemon wedges.
