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 fully combined.
02 - Add chicken thighs to the marinade, turning to coat each piece thoroughly. Cover and refrigerate for at least 2 hours, preferably overnight for maximum flavor penetration.
03 - Preheat grill, oven, or skillet to medium-high heat.
04 - Lift chicken from marinade, allowing excess to drip off. Discard used marinade.
05 - Grill or roast 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 before serving to allow juices to redistribute.
