Nigerian Boli na Obe — Baked Spiced Plantain with Groundnut Dipping Sauce

How to Make It

1. 1

   Preheat and Prepare Your Baking Tray

   Preheat your oven to 200°C (180°C fan / 400°F). Line a baking tray with parchment paper or lightly grease it. This high heat will caramelise the plantain's natural sugars without deep-frying, creating the characteristic golden crust of boli.

   Tip: If you have a grill rack, place it over the baking tray so air circulates underneath the plantain for an even char reminiscent of roadside boli.
2. 2

   Make the Spice Marinade

   In a large mixing bowl, combine the grated ginger, minced garlic, ground cameroon pepper, ground cloves, turmeric, and sea salt. Add the coconut or groundnut oil and mix everything into a paste. The turmeric adds powerful anti-inflammatory curcumin, while ginger and cloves support digestive health and blood glucose regulation.

   Tip: Allow the spice paste to sit for 2 minutes before adding the plantain so the aromatics bloom and intensify.
3. 3

   Coat the Plantain

   Add the plantain rounds and shredded uziza leaves to the spice paste bowl. Toss thoroughly until every piece is evenly coated. The uziza leaves contribute a distinctive peppery aroma that is deeply Nigerian and also provide dietary fibre and antioxidants.

   Tip: Use your hands (with gloves if preferred) rather than a spoon to ensure every plantain surface is fully covered with the spice mixture.
4. 4

   Bake Until Golden and Caramelised

   Arrange the coated plantain rounds in a single layer on the prepared baking tray, ensuring no pieces overlap. Bake for 20–25 minutes, flipping each piece at the 12-minute mark, until both sides are deep golden-brown and caramelised at the edges. The natural sugars will concentrate beautifully without added fats.

   Tip: For the last 3 minutes, switch to grill/broil mode for a slightly charred finish that mimics authentic coal-roasted boli.

   Prepare the Groundnut Dipping Sauce

   While the plantain bakes, dry-roast the groundnuts in a dry pan over medium heat for 4–5 minutes, stirring constantly, until lightly golden. Allow to cool for 2 minutes, then blend with the plum tomato, scotch bonnet, onion, ground crayfish (if using), and water until smooth. Pour into the pan and cook over low heat for 5–6 minutes, stirring, until the sauce thickens slightly and the raw tomato smell disappears. Taste and adjust seasoning.

   Tip: Do not add salt to the sauce if this recipe is being prepared for a hypertension or kidney-health meal plan. The crayfish alone provides sufficient umami.

   Plate and Serve Nigerian Style

   Arrange the hot baked plantain on a flat plate or in a small woven basket lined with banana leaf for authentic presentation. Serve the groundnut dipping sauce in a small bowl on the side. This dish is best eaten immediately while the plantain is warm and the edges are still slightly crisp.

   Tip: For a more complete snack that further lowers the glycaemic response, pair with a small handful of garden eggs (African eggplant) or a wedge of avocado pear — both are traditional Nigerian accompaniments to boli.
