01 - Set oven temperature to 425°F and line two large baking sheets with parchment paper.
02 - Peel potatoes if desired, then slice into uniform sticks about ⅜ inch thick.
03 - Place cut potatoes in a large bowl, cover with cold water, add 1 tsp sea salt, and soak for 30 minutes to remove excess starch.
04 - Drain and rinse soaked potatoes, then pat completely dry with a clean kitchen towel to ensure crispiness.
05 - Toss the dried potatoes with olive oil, black pepper, garlic powder, and smoked paprika until evenly coated.
06 - Spread fries in a single layer on the prepared sheets, avoiding overlap for even baking.
07 - Bake for 20 minutes, flip fries carefully using a spatula, rotate trays if using two, then continue baking for an additional 12-15 minutes until golden and crisp.
08 - Immediately season with extra salt if desired, then serve hot.
