Preheat oven to 450F
Line a baking sheet with parchment paper.
In a mixing bowl, combine the oil & spices.
If you are leaving the skin on, scrub your sweet potatoes really well. If not, peel your potatoes.
Cut sweet potatoes into 1/4" x 1/4" strips.
Toss the fries in the olive oil/spice mixture to coat.
Spread the fries out on a prepared baking sheet. Do not crowd them - use 2 baking sheets if you need to!
Bake for 30 minutes, turning occasionally or until fries are browned.
