01 - In a large mixing bowl, combine the yogurt, lemon juice, minced garlic, grated ginger, tandoori masala, ground cumin, ground coriander, chili powder, turmeric, garam masala, salt, and vegetable oil. Whisk until the mixture is completely smooth and homogeneous.
02 - Using a sharp knife, score the chicken pieces lightly in a few places to allow deeper flavor penetration. Add the chicken to the marinade and turn each piece to coat thoroughly and evenly. Cover the bowl with plastic wrap and refrigerate for at least 4 hours, though overnight yields the most flavorful results.
03 - Preheat the oven to 430°F. Line a baking tray with aluminum foil and set a wire rack on top to allow air circulation and even cooking around the chicken.
04 - Remove the chicken from the refrigerator and arrange the pieces on the prepared wire rack. Bake for 25 to 30 minutes, turning the pieces halfway through the cooking time, until the chicken is fully cooked through and develops a slightly charred, golden exterior.
05 - Brush the hot chicken with melted butter for added richness, if desired. Garnish generously with fresh cilantro leaves and serve alongside lemon wedges.
