Combine all marinade ingredients—chopped thyme, scotch bonnet peppers, allspice, garlic, ginger, brown sugar, soy sauce, vegetable oil, and lime juice—in a blender or food processor. Blend until smooth and fragrant, with a vibrant fiery sheen.
Pat the chicken dry with paper towels to help the marinade adhere better. Place the chicken in a large bowl and pour the marinade over, making sure every piece is thoroughly coated. Cover and refrigerate for at least 4 hours, preferably overnight, to allow the flavors to deepen.
Preheat your grill or cast-iron skillet to medium-high heat until it’s hot and shimmering, about 200°C (390°F). This will help develop a good char and crispy exterior.
Remove the chicken from the marinade, letting any excess drip off. Place the pieces skin-side down on the hot grill or skillet. Cook for 6-8 minutes until the skin is charred and crispy, listening for a sizzle and watching for grill marks.
Carefully flip the chicken using tongs, and cook for another 10-12 minutes, turning occasionally, until the juices run clear and the internal temperature reaches 75°C (165°F). The marinade should caramelize into a sticky, fiery crust.
Transfer the cooked chicken to a plate and let it rest for 5 minutes. This helps the juices redistribute, ensuring tender, juicy meat with a smoky, spicy crust.
Serve the jerk chicken hot, with lime wedges or a side of coconut rice for a complete Caribbean feast. Enjoy the smoky, spicy flavors with crispy, charred bits that burst with flavor in every bite.
