wash and peel the potato, then cut it into thin wedges

Soak the potato wedges in cold water for 30 minutes, that will release the starch and help it become crunchy

after 30 minutes drain and dry the potatoes, then add the oil and make sure they are evenly coated

heat the oven to 350°F

Get a baking sheet and leave it in the heated oven so that it gets nice and hot

When the baking sheet is hot take it out and then distribute the wedges with about 2 cm between each, make sure they are spaced or they will steam and won't become crunchy

Let it bake for 20 minutes (or more depends on your oven) and flip them on the other side half way through

After it becomes nice golden brown take it out and season with salt to taste

Put some ketchup or mayo on the side and enjoy!
