Bring 1 quart of water to a simmer and season with 3 tablespoons of salt. Using a basket or a colander, place the potatoes over the boiling water, cover, and steam them for about 10-12 minutes, or until a knife inserted comes out clean. Do not overcook to avoid a mushy texture.

Transfer the potatoes to a bowl and drizzle with olive oil. Toss carefully to ensure each fry is coated in oil.

Arrange the potatoes on a nonstick baking sheet in a single, even layer. Bake in a 450°F oven for 10 minutes, rotate the pan, and bake for an additional 5-10 minutes until they are golden brown and crisp, watching carefully to avoid burning.
