Boli (Nigerian Roasted Plantain) with Groundnut & Ube Dip

How to Make It

1. 1

   Select & Prepare Your Plantains

   Choose plantains that are yellow with only a few small black spots — firm enough to hold their shape on heat but sweet enough to caramelise beautifully. Do not peel them. Rinse the outer skin under cold water and pat dry. Using a sharp knife, make a shallow lengthwise slit along the top of each plantain without cutting all the way through — this allows even heat penetration and that signature char.

   Tip: Avoid fully black plantains for this recipe — they are too soft and will fall apart during roasting, and their very high sugar content spikes blood glucose more sharply.

   Roast the Plantains

   Place plantains directly on a dry cast iron grill pan over medium-high heat, a gas burner grate, or an outdoor charcoal grill. Roast for 10–12 minutes per side, turning with tongs every 4–5 minutes, until the skin is deeply charred and blackened all over and the flesh feels soft when gently pressed. The total roasting time is approximately 25–30 minutes. Brush the exposed flesh lightly with a few drops of olive or groundnut oil halfway through cooking to enhance caramelisation.

   Tip: For oven roasting: place plantains on a baking tray at 220°C (200°C fan) for 25–30 minutes, turning once. You will sacrifice some smokiness but retain all nutritional benefits.
3. 3

   Roast the Garden Eggs

   While the plantains roast, place the whole garden eggs directly on the same grill or burner flame. Roast for 10–15 minutes, turning occasionally, until the skin is blistered and the flesh is completely tender. Remove from heat, allow to cool for 5 minutes, then peel off and discard the charred skin. Mash the soft flesh roughly with a fork — a slightly chunky texture is desirable.

   Tip: Garden egg is rich in nasunin, a powerful antioxidant, and has a very low glycaemic index — making it an ideal companion for plantain in a diabetes-conscious meal.

   Prepare the Groundnut & Garden Egg Dip

   Dry-roast the raw groundnuts in a pan over medium heat for 6–8 minutes, stirring constantly, until golden and fragrant. Allow to cool slightly, then pulse in a blender or food processor to a coarse, crumbly paste — do not over-blend into smooth butter. In the same blender, briefly blend the tomato, tatashe, scotch bonnet, and red onion into a rough salsa. Combine the groundnut paste with the mashed garden egg and the tomato salsa in a bowl. Stir in the ground crayfish (if using), ground ehuru, uda pepper, lemon juice, and a tiny pinch of sea salt. Mix well.

   Tip: The lemon juice is not just for flavour — studies show that acidic foods eaten alongside carbohydrates help slow gastric emptying and blunt the post-meal blood glucose rise. Do not skip it.

   Peel & Plate the Boli

   Once the plantains are roasted, allow them to rest for 2 minutes — the retained steam finishes the cooking. Peel back the charred skin to reveal the golden, caramelised flesh. Slice each plantain diagonally into 4–5 thick pieces or serve whole. Arrange on a plate and spoon a generous portion of the groundnut-garden egg dip alongside or over the top.

   Tip: Serving the boli sliced rather than whole makes portioning easier and helps with mindful eating — a practical tool for weight management and portion control.

   Serve & Enjoy Mindfully

   Serve immediately while warm. This dish is best enjoyed as a mid-morning snack, light lunch, or pre-workout fuel. For a more complete meal, pair with a portion of grilled fish or boiled egg to increase protein content and further stabilise blood glucose. A chilled cup of zobo (hibiscus) drink with no added sugar makes an excellent, antioxidant-rich Nigerian accompaniment.

   Tip: Eating boli with a protein source and fibre-rich dip rather than alone significantly reduces the glycaemic impact — a simple strategy that transforms this classic street food into a clinically intelligent meal.
