01 - Using a sharp knife, make shallow cuts in the chicken pieces to allow the marinade to penetrate deeply into the meat.
02 - In a large bowl, whisk together the Greek yogurt, lemon juice, vegetable oil, garlic paste, ginger paste, coriander, cumin, garam masala, chili powder, turmeric, salt, and black pepper until completely smooth and well combined.
03 - Add the scored chicken pieces to the marinade, turning to coat each piece thoroughly. Cover the bowl and refrigerate for at least 6 hours, preferably overnight, for maximum flavor development.
04 - Preheat your oven to 450°F. Line a baking sheet with aluminum foil and place a wire rack on top to allow air circulation around the chicken.
05 - Remove chicken from the marinade, shaking off excess. Arrange pieces on the wire rack in a single layer. Bake for 25-30 minutes, turning once halfway through, until cooked through and edges are slightly charred.
06 - For authentic tandoori flavor, broil on high for 2-3 minutes at the end of cooking time, or grill over hot coals for a few minutes per side until lightly charred.
07 - Let the chicken rest for 5 minutes to allow juices to redistribute. Garnish with thinly sliced red onion, lemon wedges, and fresh cilantro leaves. Serve immediately with naan, basmati rice, or cucumber raita.
