2 sweet potatoes
1/4 cup olive or other vegetable oil
1-2 Tbsp sugar
1 Tbsp salt
1-2 Tbsp spice or spice combination of your choice: chipotle powder, smoked paprika, Chinese five-spice, pumpkin pie spice, garam masala, Cajun seasoning, etc. ( I used Chili powder, Cajun Seasoning and smoked paprika)
1 Preheat oven to 450°F. (For more crispiness, preheat your oven to 500°F.)
2 Peel the sweet potatoes and cut off the ends. Cut the potatoes in half lengthwise and then, if they are very long, in half crosswise. Cut each piece into wedges. Alternately, you can slice the peeled sweet potato into disks either with a mandoline or a sharp knife.
the oil they are coated with should keep them from sticking to the pan. If you are trying to cut fat, reduce the oil to 2 Tbsp and use a non-stick coating on the baking sheet.
5 Bake for a total of 25 to 30 minutes. After the first 15 minutes, remove the baking sheet from the oven and turn over all of the sweet potato pieces. Return to the oven and bake for another 10-15 minutes, or until they are well browned. Let cool for 5 minutes before serving.
