01 - Using a sharp knife, make shallow diagonal cuts on both sides of each chicken thigh. This helps the marinade penetrate deeper into the meat for maximum flavor absorption.
02 - In a large mixing bowl, combine Greek yogurt, lemon juice, vegetable oil, minced garlic, grated ginger, ground cumin, coriander, paprika, turmeric, garam masala, cayenne pepper, and salt. Whisk thoroughly until fully incorporated and smooth.
03 - Add the scored chicken thighs to the bowl with the marinade. Turn each piece several times to ensure complete coating. Cover tightly with plastic wrap and refrigerate for at least 4 hours, preferably overnight for optimal flavor development.
04 - Prepare your grill to medium-high heat, approximately 400°F. Clean the grates thoroughly and brush with oil to prevent the chicken from sticking during cooking.
05 - Remove chicken from the marinade, allowing excess to drip off. Place thighs on the hot grill and cook for 6 to 8 minutes per side. The chicken is done when edges are nicely charred and internal temperature reaches 165°F.
06 - Transfer grilled chicken to a clean platter and let rest for 5 minutes. This allows juices to redistribute throughout the meat for optimal tenderness.
07 - Arrange chicken on serving plates and garnish with fresh lemon wedges and chopped cilantro. Serve immediately while hot.
