In a large bowl, whisk together olive oil, apple cider vinegar, minced garlic, ground allspice, smoked paprika, cayenne pepper, ground cinnamon, ground nutmeg, dried thyme, black pepper, granulated erythritol, salt, chopped onion, minced Scotch bonnet pepper, chopped green onions, and lime juice to create the jerk marinade.
Add the chicken thighs to the marinade, ensuring each piece is thoroughly coated. Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or overnight for deeper flavor.
Preheat your oven to 375°F (190°C). Place the marinated chicken thighs skin-side up on a baking sheet lined with parchment paper.
Bake in the preheated oven for 45 minutes, or until the chicken is cooked through and the skin is crispy and caramelized.
Optional: For extra crispiness, broil the chicken thighs on high for an additional 2-3 minutes, watching carefully to prevent burning.
Remove from the oven and let the chicken rest for 5 minutes before serving.
