01 - Pat the chicken thighs completely dry using paper towels to ensure proper seasoning adherence.
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 lemon juice until thoroughly combined.
03 - Add chicken thighs to the bowl and toss vigorously to coat evenly with the spice mixture. Cover and refrigerate for minimum 30 minutes, up to 2 hours for enhanced flavor penetration.
04 - Heat grill to medium-high temperature of 400°F. Lightly oil the grates to prevent chicken from sticking during cooking.
05 - Place chicken on the preheated grill and cook for 6 to 8 minutes per side until distinct char marks appear and internal temperature reaches 165°F.
06 - Transfer chicken to a clean platter and allow to rest for 5 minutes before serving to let juices redistribute throughout the meat.
07 - Sprinkle fresh chopped parsley over the chicken and arrange lemon wedges alongside for serving.
