01 - Whisk together buttermilk, olive oil, minced garlic, kosher salt, black pepper, smoked paprika, dried thyme, dried oregano, cayenne pepper, and lemon zest in a large bowl until fully combined.
02 - Submerge chicken pieces in the marinade, turning to coat thoroughly. Cover and refrigerate for 8 hours or overnight to tenderize and infuse flavors.
03 - Preheat oven to 425°F. Line a large baking sheet with parchment paper or foil and position a wire rack on top.

05 - Brush chicken lightly with olive oil and sprinkle with additional black pepper.
06 - Roast for 40–45 minutes until skin is golden brown and juices run clear, reaching an internal temperature of 165°F.
07 - Let chicken rest for 5 minutes before serving. Garnish with chopped fresh parsley and accompany with lemon wedges.
