Blot chopped potatoes dry with a paper towel. This step can be skipped but creates crispier potatoes
Place potatoes and oil in ziploc bag, close bag and gently rotate to coat potatoes in oil.
Cover rimmed baking sheet with foil and pour potatoes in an even layer. Sprinkle with salt and bake for 20 minutes. After 20 minutes, turn potatoes, reduce heat to 400 and bake for 15 minutes longer or until crispy golden brown.
