01 - In a large bowl, whisk together olive oil, soy sauce, honey, lemon juice, garlic, smoked paprika, cumin, oregano, red pepper flakes if using, salt, and black pepper until thoroughly combined and smooth.
02 - Add chicken thighs to the bowl, turning each piece to coat completely with marinade. Cover tightly and refrigerate for minimum 2 hours, optimally overnight for deepest flavor penetration.
03 - Prepare grill, oven, or skillet to medium-high heat, approximately 375°F to 400°F.
04 - Remove chicken from marinade, allowing excess liquid to drip off. Discard all used marinade—do not reuse.
05 - Cook chicken thighs for 6 to 7 minutes per side until internal temperature reaches 165°F and skin renders crispy with caramelized spots.
06 - Let chicken rest for 5 minutes before serving to allow juices to redistribute throughout the meat.
