Verwarm de oven voor op 180°C.
Peel and slice the sweet potatoes into thick rounds. Boil in salted water for about 10 minutes until just tender (not mushy). Drain well.
Grease an oven dish. Layer the sweet potato slices inside.
In a bowl, mix melted butter, sugar, cinnamon, nutmeg, salt, and milk/cream. Pour over the sweet potatoes.
Bake uncovered for 30–40 minutes, until the top is golden, bubbly, and caramelised.
Serve warm as a side dish with roasts, stews, or braai meat.
