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 a smooth, uniform paste forms.
02 - Using a sharp knife, make shallow cuts across the surface of each chicken piece to allow deeper flavor penetration. Submerge the chicken in the marinade, turning to coat every surface thoroughly. Cover the bowl and refrigerate for at least 4 hours, or ideally overnight for maximum flavor development.
03 - Preheat the oven to 430°F. Line a baking tray with aluminum foil and set a wire rack on top to promote even air circulation and cooking.
04 - Arrange the marinated chicken pieces on the prepared rack in a single layer. Bake for 25 to 30 minutes, flipping the pieces halfway through, until the internal temperature reaches 165°F and the exterior develops a lightly charred, smoky finish.
05 - Remove the chicken from the oven and immediately brush with melted butter if desired. Garnish generously with fresh cilantro leaves and serve alongside lemon wedges.
