2 tsp olive or canola oil
1/4 tsp salt (optional)
1/8 tsp cayenne pepper
Preheat oven to 450 degrees.
Line a baking sheet that has sides with parchment paper.
Cut potato into french fry strips and place in a bowl. Add the oil, salt (if using), and cayenne pepper. Toss potatoes to coat well. Lay out in a single layer on the prepared baking sheet.
Bake at 450 degrees until tender, about 20 minutes for average size fries.
