Cut lengthways into fries. Place fries in a pot of cold water for a minimum of 30 minutes. Rinse fries and dry them off. Put the fries back into a dry bowl, and toss with 1 tbsp canola oil, until coated. Toss with salt if desired.
Prepare a baking sheet with parchment paper and lay the fries out so they are not touching.
Bake in a preheated oven at 400 ℉ for 30-40 minutes until golden. Turn the fries 2-3 times during the cook. Toss with parsley if desired.
