01 - Combine chicken thighs with lemon juice, 2 tablespoons vegetable oil, salt, black pepper, ground ginger, and minced garlic in a large bowl. Toss thoroughly to coat each piece. Cover and let marinate for at least 15 minutes, or refrigerate overnight for enhanced flavor penetration.
02 - Heat 2 tablespoons vegetable oil in a Dutch oven or large heavy pot over medium-high heat. Add marinated chicken pieces and brown on all sides, approximately 3-4 minutes per side. Transfer browned chicken to a plate and set aside.
03 - Add sliced onions to the same pot and sauté until softened and golden brown, about 5 minutes. Add red and green bell peppers and continue cooking for an additional 3 minutes until vegetables begin to caramelize.
04 - Stir in chopped tomatoes and tomato paste, cooking for 2 minutes until tomatoes break down. Add dried thyme, paprika, bay leaf, and whole scotch bonnet pepper. The scotch bonnet imparts aromatic flavor without excessive heat unless pierced.
05 - Return chicken to the pot and pour in chicken broth. Bring mixture to a gentle simmer, then reduce heat to low. Cover and cook for 30-35 minutes until chicken is tender and sauce thickens nicely. Stir occasionally to prevent sticking.
06 - Taste and adjust seasoning with additional salt and pepper if needed. Remove scotch bonnet pepper and bay leaf before serving. Ladle over steamed white rice or couscous. Garnish with chopped fresh parsley if desired.
