Oil grill grates and pre-heat it to 375°F.
In a bowl, mix the marinade ingredients - soy sauce, ginger, garlic, brown sugar, sesame oil, lime juice, black pepper, and sea salt. Stir well to create a flavorful marinade.
Next, place the chicken thighs in a resealable plastic bag or shallow dish. Pour the marinade over the chicken.
Make sure to set aside a small portion of marinade for basting later.
Ensure the chicken is well-coated. Gently massage the marinade onto the chicken for even distribution.
Seal the bag or cover the dish and refrigerate.
Let the chicken marinate for at least 1 hour, or ideally, overnight. This enhances flavor and tenderness as the marinade seeps into the meat.
Remove chicken from marinade, allowing excess to drip.
Grill chicken for 6-8 minutes per side, flipping once for caramelized exterior.
Use a meat thermometer to check if the chicken is cooked. Chicken is safe at 165°F (75°C) internal temperature.
