How to Cook Sweet Potatoes After Peeling

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.

Step 4

Preheat your oven to 400 F and bake the sweet potatoes for 15 to 20 minutes.

Step 5

Turn the slices with a spatula and continue baking the sweet potatoes for another 15 to 20 minutes, until they are fork tender.

Step 2

Things You'll Need

  • Baking dish

  • Vegetable oil spray

  • Basting brush

  • Olive oil

  • 1/8 to 1/4 tsp. black pepper

  • Spatula

  • Fork

  • Saucepan or vegetable steamer

  • Steamer basket


To prepare sweet potatoes for cooking, scrub each potato with a vegetable brush under cold running water. Peeling will be easier – and less dangerous – if you use a vegetable peeler, rather than a paring knife to peel the potatoes. Slice the sweet potatoes into 1/2-inch thick slices or cut them into french fry size strips.
