AfricanRoasted snackNigerian-American

Boli is roasted ripe plantain, usually over charcoal, served with a side of groundnut (peanut) and sometimes pepper sauce. It is street food in its purest form — no batter, no frying oil, just plantain and flame.

Where this dish comes from

Boli vendors line Lagos streets, especially in the evenings, roasting plantain over open charcoal fires. The plantain must be fully ripe — black-skinned is fine — because the sugars need to caramelize against the char.

The classic accompaniment is groundnut (roasted peanuts in their skin, often ground coarsely) and a small portion of pepper sauce. Some vendors serve boli with grilled fish — that is a full meal, not a snack.

In the diaspora, an oven broiler or outdoor grill approximates the charcoal char. It will not taste identical to Third Mainland Bridge at dusk, but the spirit transfers.

Ingredients

  • 4 large very ripe plantains (about 2 lbs / 900 g), skins on
  • 1 tsp (5 g) salt, for sprinkling
  • 1 cup (150 g) roasted peanuts (groundnut), for serving
  • Pepper sauce, for serving (optional — see gizdodo pepper sauce or any Nigerian pepper stew)

The method

  1. Step 1: Leave plantain skins on. Cut a shallow slit lengthwise along each plantain — this prevents bursting and helps heat penetrate.

  2. Step 2: If using a grill: set plantains over medium-high charcoal or gas flame. Turn every 5 minutes for 20–25 minutes until the skin is blackened and the flesh inside is soft and caramelized.

  3. Step 3: If using an oven: preheat broiler to high. Place plantains on a foil-lined tray and broil 6 inches from heat, turning every 5 minutes, for 20–25 minutes until charred outside and tender inside.

  4. Step 4: The plantain is done when you can press the skin and feel no firm resistance — the flesh should be soft like mashed banana.

  5. Step 5: Peel away the charred skin (some char adds flavor; scrape excess). Split open lengthwise and sprinkle with salt.

  6. Step 6: Serve with roasted peanuts and pepper sauce on the side. Eat with your hands.

Family notes ✎

  • Boli is strongly associated with Lagos and the southwest; other regions have roasted plantain traditions with different names and accompaniments.
  • Very ripe plantain (nearly black skin) produces the sweetest boli — do not use yellow-firm plantain.
  • Nigerian-American block parties with charcoal grills often produce excellent diaspora boli — the technique travels better than many dishes.

Substitutions

  • Preferred: Charcoal grill for authentic smoke and char.
  • Emergency: Oven broiler — works well, lacks smoke.
  • Do Not Substitute: Pan-fried plantain and calling it boli — boli requires dry heat and char, not oil.
