Prep & Rice Rinse — Rinse the rice in cold water until runoff is mostly clear; drain and let sit 10 minutes. Preheat the oven to 400°F (200°C) if roasting chicken.
Marinate Chicken — In a bowl, combine chicken, oil, lemon juice, smoked paprika, garlic powder, onion powder, thyme, salt and pepper. Toss well and let rest 15–30 minutes (or refrigerate up to 4 hours).
Blend Tomato Base — In a blender or food processor combine red bell pepper, crushed tomatoes (or fresh tomatoes), and 2 tablespoons water; purée until smooth. Set aside.
Roast: Place chicken skin-side up on a roasting tray. Roast at 400°F (200°C) for 30–40 minutes until golden and internal temperature reaches 165°F (74°C).
Or Pan-sear: Heat 2 tablespoons oil in a skillet over medium-high heat. Sear chicken skin-side down 6–8 minutes until golden, flip and cook 6–10 minutes until done. Finish in oven if needed.
Make the Jollof Stew — Heat 1/2 cup oil in a heavy, wide pot over medium heat. Add chopped onion and a pinch of salt; sauté 7–10 minutes until soft and translucent. Add minced garlic and ginger; cook 30–45 seconds. Stir in the tomato paste and cook 2–3 minutes until it darkens slightly. Add the blended tomato-pepper purée and whole Scotch bonnet (if using whole) and simmer uncovered 12–20 minutes, stirring occasionally, until the mixture reduces and concentrates. Add smoked paprika, thyme, bay leaves and bouillon; season to taste.
Add Rice & Stock — Stir the drained rice into the reduced tomato stew to coat grains. Pour in 3 cups hot chicken stock (use up to 3 1/2 cups if needed for your rice). Stir once, bring to a boil, then reduce heat to low, cover tightly and simmer 15–22 minutes. Do not lift the lid frequently.
Finish Rice — After rice is tender and most liquid absorbed, stir in butter (if using) and fold in frozen vegetables. Remove whole Scotch bonnet if used. Turn off heat and let rice rest, covered, 5–10 minutes to steam finish.
Plate & Serve — Fluff rice gently with a fork. Arrange roasted or seared chicken over or beside the rice. Spoon any chicken juices onto the dish. Garnish with chopped parsley or scallions and serve with fried plantains or a crisp salad if desired.
