If baking in an oven, preheat the oven to 425 degrees F. If you have a convection function, use that setting as well.
Fill a large stock pot with water and generously season the water with 2-3 tbsp of kosher salt. Bring the water to a boil.
Pour the yuca into the boiling water and cook until fork tender, about 5 minutes. NOTE: You do not want these to be too soft. You want the fork to stick in and not easily slide out.
Remove the yuca from the boiling water and drain into a collander. Spray with cold water from the faucet for 1-2 minutes to neutralize the temperature.
Toss the boiled yuca fries in olive oil, making sure to fully coat each one. Season generously with salt.
Bake at 425 degrees for 20-30 minutes (or until lightly golden brown,) flipping halfway through. Or, air fry for 20 minutes at 400 degrees, until lightly golden brown. NOTE: You don't want to over bake or air fry them until they are medium to dark golden brown because they will become tough to chew and too crunchy without a starchy inside.
