Baking Sweet Potatoes. 1  Preheat oven to 400Â°F. 2  With a fork, pierce sweet potato skin 5-6 times. 3  Place on baking sheet lined with foil. 4  Bake until tender, 45 minutes to 1 hour.
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. Return to the oven and bake for another 5-15 minutes, or until they are well browned. Cooking time depends on the temperature of the oven (500F will need less cooking time than 450F) and the size and thinness of the sweet potato wedges.
