Peel sweet potato and cut into julienne strips, using a Julienne Peeler.
Add sticks to a mixing bowl. Add coconut oil and salt. Toss to coat. Spread sticks evenly over a large parchment-lined or non-stick baking sheet. Stir every 10 minutes and continue to bake until crispy, approximately 30 minutes.
Watch sticks closely to make sure they don't burn. Allow to cool completely before adding to an airtight ziplock bag.
