01 - Preheat oven to 425°F. Line two large baking sheets with parchment paper.
02 - Wash and optionally peel potatoes. Slice into ⅜-inch thick sticks for consistent cooking.
03 - Submerge cut potatoes in cold water for at least 30 minutes to remove excess starch. Drain and pat dry thoroughly with a clean towel.
04 - In a large bowl, combine potatoes with olive oil, sea salt, black pepper, garlic powder, and smoked paprika. Toss until fries are evenly coated.
05 - Place fries in a single layer on prepared baking sheets, ensuring pieces do not touch to maximize crispiness.
06 - Bake for 20 minutes. Flip fries using a spatula, rotate trays, then bake an additional 15 to 20 minutes until golden and crispy.
07 - Remove fries from oven and immediately sprinkle with extra sea salt. Serve while hot.
