01 - Combine chili peppers, garlic, red bell pepper, smoked paprika, oregano, cumin, salt, black pepper, olive oil, red wine vinegar, lemon juice, and zest in a blender. Blend until completely smooth to create a vibrant red marinade.
02 - Set aside 3 tablespoons of the blended marinade in a separate small bowl. This reserved portion will be used for basting during cooking and as an extra serving sauce.
03 - Rub the remaining marinade thoroughly over the chicken, ensuring all surfaces are evenly coated. Place the chicken in a large dish or resealable bag, cover tightly, and refrigerate for a minimum of 2 hours. For optimal flavor penetration, marinate overnight.
04 - Preheat your grill or oven to 400°F. If using a grill, lightly oil the grates to prevent sticking and ensure easy removal.
05 - Arrange chicken skin-side up on the grill grates or in a roasting pan. Cook for 35 to 40 minutes, turning once midway through cooking. Baste generously with the reserved marinade during the last 10 minutes. Continue until chicken reaches an internal temperature of 165°F and the skin is nicely charred and crispy.
06 - Remove chicken from heat and let rest for 5 minutes to allow juices to redistribute. Cut into serving pieces and arrange on a platter. Garnish with fresh parsley and serve with lemon wedges on the side.
