01 - In a large bowl, whisk together olive oil, lemon juice, smoked paprika, garlic powder, onion powder, thyme, oregano, cayenne, black pepper, salt, and white pepper until fully combined.
02 - Add chicken thighs to the bowl, turning to coat thoroughly with the marinade. Cover and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavor penetration.
03 - Preheat grill to medium-high heat, approximately 400°F. Lightly oil the grates to prevent sticking.
04 - Remove chicken from marinade, allowing excess to drip off. Grill thighs 6–8 minutes per side until nicely charred and internal temperature reaches 165°F.
05 - Transfer to a plate, tent loosely with foil, and let rest 5 minutes before serving to allow juices to redistribute.
