Line bottom of oven with foil to catch drips from the sweet potatoes as they bake. They can get pretty sticky.

Preheat oven to 400 degrees F.

Wash sweet potatoes and remove any bad spots that you see.

Prick each sweet potato with a fork a few times around the potato.

Wrap each sweet potato separately in a square of foil.

Place each sweet potato in heated oven and bake for 40-50 minutes until done. You can tell it's done if the sweet potato is easily squeezed and gives when gentle pressure is applied, or when a fork can easily pierce the potato.

Remove from oven, unwrap, and serve.
