01 - In a large mixing bowl, whisk together the lime juice, olive oil, chopped cilantro, minced garlic, cumin, chili powder, smoked paprika, kosher salt, and black pepper until well blended.
02 - Add the chicken thighs to the marinade, ensuring each piece is thoroughly coated. Cover and refrigerate for at least 30 minutes and up to 4 hours for best flavor infusion.
03 - Heat a grill or grill pan to medium-high heat, approximately 400°F.
04 - Remove chicken thighs from the marinade, allowing excess liquid to drip off. Discard any remaining marinade.
05 - Place chicken thighs on the preheated grill and cook for 6 to 8 minutes per side, or until they are well charred and reach an internal temperature of 165°F.
06 - Transfer grilled chicken to a serving platter, tent loosely with foil, and let rest for 5 minutes before serving. Garnish with extra chopped cilantro and lime wedges if desired.
