Nigerian Boli (Roasted Plantain) with Spiced Groundnut Sauce

How to Make It

1. 1

   Select and Prepare the Plantains

   Choose plantains that are yellow with black spots — ripe but still firm to touch. Peel and slice each plantain lengthwise into halves or leave whole for traditional Boli presentation. Pat dry with a clean cloth to remove surface moisture, which helps achieve a better roast.

   Tip: Avoid fully blackened overripe plantains — they have a higher glycemic index and will burn quickly during roasting.
2. 2

   Dry-Roast the Groundnuts

   Place raw groundnuts in a dry skillet or pan over medium heat. Stir continuously for 8–10 minutes until golden brown and aromatic. Remove from heat, allow to cool for 3 minutes, then rub off the skins using a clean kitchen towel. Transfer to a blender or mortar and grind into a coarse, textured paste — do not over-blend into a smooth butter.

   Tip: Grinding coarsely preserves fiber content and slows fat absorption, making the sauce more diabetes-friendly.

   Prepare the Spiced Groundnut Sauce

   Blend the ata rodo, fresh tomatoes, half the red onion, garlic, and ginger into a smooth paste. Heat oil in a small saucepan over medium heat and sauté the blended paste for 5–7 minutes, stirring frequently, until the raw smell disappears and the oil begins to separate. Stir in the ground groundnut paste, turmeric, black pepper, crayfish (if using), and just a pinch of salt. Add low-sodium stock or water and stir well to a thick, pourable consistency. Cook for a further 3–4 minutes on low heat, then fold in the chopped uziza or scent leaves at the very end.

   Tip: Adding greens at the end preserves their volatile oils, chlorophyll, and heat-sensitive vitamins — especially important for anti-inflammatory benefit.

   Roast the Plantains

   Preheat a grill pan, outdoor grill, or oven grill to high heat (200°C / 390°F). Place the plantain halves directly on the grill grate or grill pan with no oil. Roast for 5–7 minutes on each side, turning once, until dark grill marks appear and the flesh is soft and caramelized through. The natural sugars will char slightly at the edges — this is correct and desirable.

   Tip: No oil is needed for roasting; the plantain's natural sugars caramelize beautifully on their own, keeping calorie and fat content low.

   Plate and Serve

   Arrange the roasted plantain on a plate and spoon the warm spiced groundnut sauce generously alongside or over the top. Garnish with the remaining thinly sliced raw red onion for freshness, crunch, and added prebiotic benefit. Serve immediately while plantain is hot.

   Tip: For a more balanced meal and added protein, serve alongside a boiled egg, grilled fish (like titus/mackerel), or a side of garden egg stew.
