How to Bake Your Sweet Potatoes

Updated April 17, 2017

Baked sweet potatoes are healthy vegetables that need little or no additives when baked. A single cup of baked sweet potato has 769 per cent of the daily recommended amount of vitamin A, as well as good levels of vitamin C, manganese and vitamin B6. A highly anti-inflammatory food, sweet potatoes also have a low glycemic level. Sweet potatoes can be baked a day ahead of time and refrigerated for reheating without altering the flavours of the potato.

Wash the outside of the skin of a long and small to medium-wide sweet potato using a vegetable scrub brush.

Wrap the sweet potato with a single layer of aluminium foil so the entire potato is covered; wrapping the potato prevents the skins from expanding and busting, as the syrup of the sweet potato is released during baking.

Place the sweet potato on a baking pan to prevent the sweet potato juices from leaking during the baking process. Position the baking pan in the centre of the oven.

Bake the sweet potato at 204 degrees Celsius for 60 to 75 minutes. Remove the foil and squeeze the wrapped potato gently; if the potato is baked it will be soft; otherwise return it to the oven and continue baking in 15-minute intervals until the potato is done.

Serve the baked potato by removing the outer skin. Season the sweet potato with butter or cinnamon and brown sugar, if desired, or plain.

Wash and peel a sweet potato using a potato peeling tool or knife.

Slice the potato lengthwise in half. Cut the halves of the potato lengthwise again so you have four equal pieces; you can cut the pieces in half again, if desired for thinner slices.

Arrange the potato slices in a single layer on a baking pan.

Drizzle olive oil over the potato slices and flip them over. Add olive oil to this side of the potatoes. Sprinkle coarse salt and ground black pepper over the potatoes to taste.

Bake the potato slices at 204 degrees Celsius for 20 to 30 minutes or until they brown on the edges. Flip the potato slices over halfway through the baking process.
