01 - Using a sharp knife, lightly score the chicken thighs with shallow cuts to allow the marinade to penetrate deeply into the meat.
02 - In a large bowl, whisk together the Greek yogurt, lemon juice, vegetable oil, minced garlic, grated ginger, ground cumin, coriander, paprika, turmeric, garam masala, cayenne pepper, and salt until thoroughly combined.
03 - Add the scored chicken thighs to the marinade, turning to coat completely. Cover the bowl and refrigerate for at least 4 hours, preferably overnight for maximum flavor penetration.
04 - Preheat grill to medium-high heat (approximately 400°F). Lightly oil the grates to prevent sticking during cooking.
05 - Remove chicken from marinade, allowing excess to drip off. Place on the preheated grill and cook for 6–8 minutes per side, or 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 allow juices to redistribute. Serve hot, garnished with fresh lemon wedges and chopped cilantro.
