Instructions

  1. Preheat the oven to 400 degrees.
  2. Slice each potato lengthwise into 1/4-inch ovals, then slice each ovallengthwise into matchsticks (i use a mandoline which makes this go much quicker).
  3. Coat a baking sheet with 3 sprays of the vegetable oil.
  4. Combine the egg whites and cajun spice in a bowl.
  5. Add the matchstick potatoes and mix to coat.
  6. Pour the coated potatoes onto the prepared baking sheet and spread them out into a single layer, leaving a little space between them.
  7. Place the baking sheet on the bottom shelf of the oven.
  8. Bake for 40 to 45 minutes, until the fries are crispy, turning them every 6 to 8 minutes with a spatula so that they brown evenly.
  9. Serve immediately.
