Follow these steps to create your delicious Jamaican Brown Stew Chicken:

1. Marinate the Chicken: In a large bowl, combine the chicken pieces with allspice, thyme, black pepper, and salt. Let it marinate for at least 30 minutes.
2. Heat the Oil: In a large pot, heat the vegetable oil over medium heat.
3. Brown the Chicken: Add the marinated chicken to the pot and brown it on all sides for about 5-7 minutes. Remove the chicken and set aside.
4. Sauté the Vegetables: In the same pot, add the sliced onion, bell pepper, garlic, and ginger. Sauté until the onion is translucent.
5. Add Carrots: Stir in the sliced carrots and cook for another 2-3 minutes.
6. Return the Chicken: Place the browned chicken back into the pot.
7. Add Liquids: Pour in the chicken broth, soy sauce, and brown sugar. Stir to combine.
8. Simmer: Bring the mixture to a boil, then reduce the heat to low. Cover and let it simmer for 30-40 minutes, or until the chicken is cooked through and tender.
9. Add Green Onions and Scotch Bonnet: In the last 10 minutes of cooking, add chopped green onions and the whole Scotch bonnet pepper (if using) for added flavor.
10. Adjust Seasoning: Taste and adjust seasoning as needed, adding more salt or sugar if necessary.
11. Garnish and Serve: Once cooked, garnish with fresh parsley before serving.
