In Tonga, the prized ufi (yam) is traditionally cooked low and slow until its flesh turns tender, sweet, and faintly nutty. This home-kitchen version wraps whole yams in foil and roasts them with salted coconut cream for an authentic island-style side dish. Serve it alongside grilled fish or lu pulu for a true Tongan plate.

Ingredients
For the Baked Yams
- 2 medium yams (ufi), about 1.5 lb each, scrubbed
- 1 cup thick coconut cream, divided
- 1 tsp fine sea salt, divided
- 2 green onions, thinly sliced (optional)
- 1 lime, cut into 8 wedges
Tongan yam (ufi)
Thick coconut cream
Fine sea salt
Green onions
LimeDirections
Preheat the oven to 375°F (190°C). Pat the scrubbed yams dry and pierce each one 6-8 times with a fork to let steam escape.
Set each yam on a large square of heavy-duty aluminum foil. Drizzle 2 tablespoons of the coconut cream over the tops and sprinkle with half of the sea salt.
Wrap the foil tightly around each yam, place them on a rimmed baking sheet, and bake for 1 hour 15 minutes, until a thin knife slides into the center with no resistance.
While the yams bake, warm the remaining coconut cream with the rest of the salt in a small saucepan over low heat for 4-5 minutes; do not let it boil, just keep it hot.
Carefully unwrap the yams (a burst of steam will escape) and transfer them to a warm serving platter, keeping the foil open like a boat to catch any cream.
Using a sharp knife, slice each yam open lengthwise through the skin, then gently squeeze the ends to push the flesh up and out.
Fluff the exposed flesh with a fork, then spoon the warm salted coconut cream over the top, letting it drip down into the flesh and pool in the foil.- Scatter green onions over the yams and serve right away with lime wedges for squeezing over each portion.
Cook’s Notes
- True Tongan ufi (Dioscorea) can be replaced with any standard supermarket yam or even Japanese nagaimo; just adjust bake time by 10-15 minutes for very large roots.
- Traditionally, Tongan families cook yams in an underground earth oven called an umu; this foil method recreates that trapped-steam environment in a regular oven.
- Fresh, refrigerated coconut cream gives a noticeably richer, less sweet result than canned varieties labeled 'coconut milk.'
- Cooked yams keep 3 days in the fridge; reheat wrapped in foil at 300°F for about 20 minutes to preserve moisture.
- For a more festive Tongan presentation, top with a spoonful of warmed honey and a pinch of toasted coconut flakes alongside the coconut cream.
