01 - Make shallow slashes in the chicken pieces with a sharp knife to help the marinade penetrate deeply into the meat.
02 - Whisk together the yogurt, lemon juice, ginger-garlic paste, oil, salt, cumin, coriander, garam masala, smoked paprika, chili powder, turmeric, and cayenne pepper in a large bowl until thoroughly combined.
03 - Add the chicken pieces to the marinade, ensuring they are completely coated. Cover and refrigerate for at least 6 hours, preferably overnight for maximum flavor development.
04 - Preheat your oven to 425°F or heat a grill to medium-high temperature.
05 - Place the marinated chicken pieces on a wire rack set over a baking sheet, or directly on the grill grates if using outdoor cooking method.
06 - Roast or grill for 25-30 minutes, turning once halfway through cooking, until the chicken is cooked through with an internal temperature of 165°F and develops a slight char on the exterior.
07 - Remove from heat and let the chicken rest for 5 minutes. Garnish generously with fresh cilantro and serve accompanied by lemon wedges and sliced onions.
