Sweet potatoes can either be boiled or steamed.

It all depends on personal preference, but the sweet potato taste will be different in these two ways, the flavor will be more sweet when steamed. If you boil them in water, the sweet potatoes will be more moist, but the sweetness will be a little worse than the steamed ones.
