These oven fries are just as crunchy as if they had been deep-fried.
Preheat oven to 450 degrees, with racks in top third and middle. Arrange potatoes in a single layer on two rimmed baking sheets and toss each with 2 tablespoons oil. Season with salt and pepper.
Bake until golden brown, crisp, and cooked through, 40 minutes, rotating sheets and flipping potatoes halfway through.
