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 emulsified.
02 - Add chicken thighs to the bowl and turn to coat each piece completely. Cover and refrigerate for minimum 2 hours, preferably overnight for optimal flavor penetration.
03 - Preheat grill, oven to 400°F, or skillet over medium-high heat until properly heated.
04 - Take chicken from marinade, allowing excess liquid to drip off. Discard all used marinade safely.
05 - Grill or roast chicken thighs 6–7 minutes per side until internal temperature reaches 165°F and skin becomes crisp and deeply caramelized.
06 - Transfer chicken to a cutting board and let rest 5 minutes before serving to redistribute juices throughout the meat.
