01 - Whisk together olive oil, soy sauce, honey, lemon juice, garlic, smoked paprika, cumin, oregano, red pepper flakes if using, salt, and black pepper in a large bowl until thoroughly combined.
02 - Add chicken thighs to the bowl, turning to coat each piece completely. Cover and refrigerate for at least 2 hours, preferably overnight for optimal flavor penetration.
03 - Preheat grill, oven, or skillet to medium-high heat (approximately 375-400°F).
04 - Lift chicken from marinade, allowing excess liquid to drip off. Discard all used marinade.
05 - Grill, roast, or pan-sear chicken thighs for 6-7 minutes per side until internal temperature reaches 165°F and skin is crisp and caramelized.
06 - Let chicken rest for 5 minutes to allow juices to redistribute before serving.
