Sweet potatoes add good taste, a splash of color and a slew of important nutrients to your dinner table. Each 3.5 oz. serving supplies twice your daily requirement of vitamin A, 42 percent of your daily vitamin C requirement, 8 percent of your daily thiamine requirement and calcium, iron and fiber. When you cook sweet potatoes after peeling, prevent the loss of essential nutrients, especially the water soluble vitamins C and thiamine, by cooking them quickly, using little to no additional liquid.
Spray a baking dish with vegetable oil spray.
Arrange peeled sweet potato slices in a single layer in the baking dish.
Baste the tops of the sweet potato slices with olive oil and season them with a sprinkling of black pepper.
Preheat your oven to 400 F and bake the sweet potatoes for 15 to 20 minutes.
Turn the slices with a spatula and continue baking the sweet potatoes for another 15 to 20 minutes, until they are fork tender.
Add 1 to 2 inches of water to a saucepan or vegetable steamer and bring the water to a full boil on your stove.
Add sweet potato slices or strips to a steamer insert or basket.
