01 - Using a sharp knife, make shallow cuts in 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 in a large bowl until fully incorporated.
03 - Add chicken thighs to 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 thoroughly and brush with oil to prevent sticking during cooking.
05 - Remove chicken from marinade, allowing excess to drip off. Grill for 6–8 minutes per side until edges are lightly charred and internal temperature reaches 165°F.
06 - Transfer chicken to a platter and let rest for 5 minutes to redistribute juices. Serve hot with fresh lemon wedges and chopped cilantro sprinkled on top.
