Heat the oven to 425°F. Place a baking sheet in the oven to preheat. The fries should hit a hot sheet to prevent sticking. If you hear a sizzle when placing the fries, it's perfect. Return the sheet to the oven quickly.

Boil 2-3 liters of salted water. Wash the potatoes and slice them into thick wedges. Add the wedges to the boiling water and cook for exactly 3 minutes. Drain the potatoes and coat them with olive oil, salt, and pepper. You can add extra seasonings like herbs or chili flakes, but they taste great with just salt and pepper.

Arrange the potato wedges in a single layer on the hot baking sheet. Bake at 425°F for about 30 minutes, flipping the wedges halfway through. Once done, sprinkle with kosher salt and serve.
