01 - Using a sharp knife, make shallow cuts across the chicken thighs to help the marinade penetrate deeply into the meat.
02 - Whisk together Greek yogurt, lemon juice, vegetable oil, minced garlic, grated ginger, cumin, coriander, paprika, turmeric, garam masala, cayenne pepper, and salt until thoroughly combined.
03 - Add chicken thighs to the bowl with the marinade, turning to coat completely. Cover and refrigerate for at least 4 hours or overnight for maximum flavor penetration.
04 - Heat grill to medium-high temperature (400°F). Clean grates and lightly oil to prevent 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 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.
