01 - Whisk together olive oil, soy sauce, honey, lemon juice, minced 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 and turn to coat each piece completely. Cover and refrigerate for at least 2 hours, or preferably overnight for maximum flavor absorption.
03 - Preheat grill, oven, or skillet to medium-high heat (approximately 375°F-400°F).
04 - Remove chicken from the marinade, allowing excess liquid to drip off. Discard the used marinade safely.
05 - Cook chicken thighs for 6-7 minutes per side until the internal temperature reaches 165°F and the skin is crispy and caramelized.
06 - Let the chicken rest for 5 minutes before serving to allow juices to redistribute.
