Cover 2 large sheet pans with foil, and spray the foil with cooking spray. Preheat oven to 375 degrees.

Cut the ends off the sweet potato, and cut the potato in half crosswise. Remove skin with a knife or vegetable peeler.

Use a vegetable spiralizer to cut each half of the sweet potato into shoestring-size spirals.

Place the sweet potato spirals in a large bowl with olive oil and seasoning, and toss with your hands until the oil and spices are evenly distributed.

Spread the sweet potato spirals out as evenly as possible on the 2 foil-covered baking sheets.

Bake for 10 minutes, then stir the sweet potato spirals and spread them out again.

Bake 10-15 minutes more, watching the sweet potatoes so they don't burn.
