In a medium bowl, toss sweet potatoes with olive oil, salt, garlic powder and chipotle chile powder.
Spread potatoes on a baking sheet. Avoid crowding so potatoes get crisp. Bake 15 minutes. Turn and bake an additional 10-15 minutes. Ovens may vary so keep an eye on them and be sure to cut all the potatoes the same size to ensure even cooking.
Notes
These fries are best served immediately for maximum crispiness.
