Bougna (Kanak Earth-Oven Parcel)
The Kanak feast dish of New Caledonia: root vegetables and chicken packed with thick coconut milk into banana leaves and buried for two hours over hot stones. Passing the leaves through a flame so they fold without splitting, and sealing the parcel completely, is the whole technique — a leaking parcel simply dries out.

Steps
- ⏲ 10 min
Pass the banana leaves over a gas flame or a hot dry pan for a few seconds each side, until they darken and turn glossy. Skip this and they split as you fold them, and every drop of the coconut milk escapes.
- ⏲ 20 min
Peel the taro, yam, sweet potato and cassava and cut them into 4–5cm chunks, all roughly the same size so they finish together. Peel the taro thickly — a thin peel leaves the throat-catching sap behind.
- ⏲ 8 min
Cut the chicken into large pieces on the bone and salt it. Small pieces will have fallen apart completely after two hours.
- ⏲ 15 min
If using fresh coconuts, grate the flesh, add a splash of warm water and squeeze; the first thick pressing is your cooking liquid. If using tins, do not dilute them.
- ⏲ 5 min
Layer three or more banana leaves in alternating directions and spread the root vegetables over the base. They hold the meat off the bottom so nothing catches.
- ⏲ 4 min
Set the chicken on the vegetables, tuck the plantains into the gaps and pour in the coconut milk — two-thirds of the way up is plenty, since the vegetables drink it as they cook.
- ⏲ 10 min
Fold the leaves up from every side, seal with no gaps, and tie firmly in a cross with string. For an oven, wrap the whole parcel again in foil. How well you seal it decides the dish.
- ⏲ 120 min
Earth oven: burn wood in a pit to heat stones, rake out the embers, set the parcel on the hot stones, cover with leaves and then earth, and leave it buried for 2 hours.
- ⏲ 120 min
In an oven, bake at 180°C for 2 hours. In a steamer, fill the water generously and steam for 2 hours. Neither gives you the earth-oven smoke, but the texture and flavour are close.
- ⏲ 15 min
Rest the parcel 15 minutes, then open the leaves at the table. It is not transferred to a serving dish — people help themselves straight from the leaf, with the chillies alongside.
Tips & Variations
Variations
- Coastal fish bougna: whole white fish instead of chicken. It cooks far faster, so give the vegetables a 30-minute head start before adding it.
- Lobster bougna: freshwater prawns or lobster for big occasions — the most lavish version, and the one coconut milk suits best.
- Vegetarian bougna: root vegetables and coconut milk alone stand up perfectly well. A few pieces of green papaya add a layer of sweetness.
- Oven bougna: city kitchens in New Caledonia use the oven now. Double-wrapped in foil the liquid stays trapped and the result is close to the pit.
- Steamed bougna: with no oven, a large steamer is arguably better — nothing dries out and the leaf perfume comes through.
- Swap the roots freely: taro, yam, sweet potato, cassava — whatever you can get. Just use two or three different ones so the texture is not monotonous.
Tips
- Always flame the banana leaves. It takes seconds. Raw leaves crack as you fold them, and a cracked parcel leaks until the food is dry.
- Never dilute the coconut milk. The roots absorb liquid for two hours, so if you start thin there is no flavour left at the end.
- Seal the parcel completely. This is effectively a pressure cooker built out of leaves; any leak and two hours of cooking still gives you dry food.
- Cut the chicken large. Two hours of gentle heat leaves nothing of small pieces.
- Peel taro thickly. A thin peel leaves the irritant sap in; wear gloves if your hands are sensitive.
- Serve it in the leaf. At a Kanak gathering, opening the parcel is part of the dish. Plating it up scatters the juices and the aroma.
- Bougna is what is cooked to receive guests at a Kanak coutume, so in New Caledonia the word carries the occasion as much as the recipe.
