01 - Using a sharp knife, make shallow cuts in the chicken thighs to help the marinade penetrate deeper into the meat.
02 - In a large bowl, whisk together Greek yogurt, lemon juice, vegetable oil, garlic, ginger, cumin, coriander, paprika, turmeric, garam masala, cayenne pepper, and salt until thoroughly combined.
03 - Add the scored chicken thighs to the bowl and turn to coat completely. Cover and refrigerate for at least 4 hours, preferably overnight for maximum flavor infusion.
04 - Heat grill to medium-high temperature (approximately 400°F). Lightly oil the grates to prevent the chicken from sticking during cooking.
05 - Remove chicken from marinade, allowing excess to drip off. Grill for 6–8 minutes per side until edges are nicely charred and internal temperature reaches 165°F.
06 - Transfer grilled chicken to a cutting board and let rest for 5 minutes to redistribute juices. Serve hot with lemon wedges and fresh cilantro sprinkled on top.
