How to cook it
- Heat the oven hot, around 220°C / 425°F.
- To roast whole: prick the skin and roast until a knife slides through with no resistance, 45 to 60 minutes.
- To roast in pieces: cube, toss with a little oil, and roast until tender and caramelized at the edges, about 30 minutes.
- No peeling needed. The skin is edible and holds together.
In the kitchen
Cubed and roasted they crisp at the edges and go tender inside, ready for a bowl, a curry, a hash, or a taco. Boiled and mashed they thicken a soup or take over half the work in a pancake or a baked good. The one thing to avoid is a low, slow simmer that leaves them waterlogged; they want dry heat, or a quick one.
They lean sweet, so they take a savory counterweight well: cumin, smoked paprika, chili, a squeeze of lime, and salt with a heavier hand than you’d expect. Unlike the dried goods on the rest of these shelves, sweet potatoes keep a clock. This is the pantry item you buy for the week, not the year.
Health
A sweet potato is a whole-food carbohydrate with the fiber and slow digestion the refined versions lose. Its orange flesh is dense in beta-carotene, the pigment the body converts to vitamin A. Roasting it in its skin keeps most of it.
It sits in the vegetable and tuber groups every framework on this page counts, and it does that as a filling staple rather than a token vegetable. That is what earns a starchy root a place beside the beans and grains. The frameworks and research below show where it lands.
