Carefully spread the sweet potatoes out in a single layer on the baking sheet. (Watch out, the pan is hot!) 5 Bake: Bake for a total of 15 to 25 minutes. After the first 10 minutes, remove the baking sheet from the oven and use tongs to turn over all of the sweet potato pieces.
To cook sweet potatoes in the oven, preheat your oven to 400 Â°F (204 Â°C). While your oven is preheating, pierce each sweet potato 6-12 times with a fork and then rub olive oil over them. Wrap each potato loosely in aluminum foil and place them directly on the middle rack in your oven.
