Make the Jerk Marinade
Combine all marinade ingredients in a blender or food processor. Blend until smooth, adding 1–2 tablespoons of water if needed. Taste and adjust salt and heat as desired.
Prepare the Chicken
Do not wash the chicken, as this can cause cross-contamination. Pat it dry with paper towels.
Score the chicken deeply with a knife to help the marinade penetrate.
Rub the jerk marinade generously over the chicken, including under the skin. Place it in a sealed container or ziplock bag.
Marinate for at least 12 to 24 hours. Overnight is ideal for authentic, deep flavor.
Grill Traditionally (Preferred Method)
Prepare the grill using charcoal or wood. Pimento (allspice) wood is traditional—soak the wood chips in water and add them to the coals for a rich, smoky flavor.
Use indirect heat. Grill the chicken over medium-low heat (325–350°F) to avoid burning. Place the chicken skin-side up, away from direct flames.
Mix 2 tablespoons of oil with 1–2 tablespoons of leftover marinade (boil the marinade first to kill any bacteria). Brush onto the chicken every 10–15 minutes.
Grill for 45 to 60 minutes, turning occasionally, until the internal temperature reaches 165°F (74°C).
Oven Method (If Grilling Isn’t Possible)
Preheat the oven to 375°F (190°C).
Place the chicken on a rack set over a baking sheet to allow airflow.
Bake for 40 to 50 minutes, basting with oil every 10 minutes. Finish under the broiler for 2–3 minutes to crisp the skin.
