Using a spiralizer, process potatoes into long spirals. Toss spiraled potatoes with olive oil. Arrange in a single layer on a baking sheet (hint: line your baking sheet with foil for easier clean up). Sprinkle with salt and pepper. Bake at 400 for 25 min. Turn broiler on and broil 2-5 min or until browned and crispy. See notes about alternatives to a spiralizer.
Notes
If you don’t have a spiralizer, you might want to get one just so you can make these amazing shoestring sweet potatoes! Fret not, though. If you don't have a spiralizer you can shred the potatoes with a cheese grater or a food processor.
