Place raw cut “fries” into a colander and rinse under cold water (to remove the starchy exterior of the potato). Then, pat “fries” dry with a towel to remove as much moisture as possible.
Place “fries” on to a sheet tray, drizzle with the oil and salt, and toss to coat.
Bake for 20 minutes, then toss and bake for an additional 10 minutes (for a total of 30 minutes).
