01 - Pat the chicken thighs completely dry using paper towels to ensure proper seasoning adherence and grill marks.
02 - In a large mixing bowl, whisk together olive oil, smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, black pepper, kosher salt, white pepper, and fresh lemon juice until thoroughly combined.
03 - Add chicken thighs to the bowl and toss vigorously to coat every piece evenly. Cover and refrigerate for at least 30 minutes, or up to 2 hours for maximum flavor penetration.
04 - Heat grill to medium-high temperature (400°F). Lightly oil the grates to prevent sticking and ensure easy release.
05 - Place chicken on the preheated grill and cook for 6 to 8 minutes per side. Develop a nice char and cook until internal temperature reaches 165°F for safe consumption.
06 - Remove chicken from grill and let rest for 5 minutes before serving to allow juices to redistribute throughout the meat.
07 - Transfer to serving platter, sprinkle with fresh chopped parsley, and accompany with lemon wedges for squeezing over the chicken.
