Preheat oven to 425 degrees. Wash, and cut potatoes into quarters. Place potatoes in a large bowl and coat with vegetable oil. Stir potatoes to coat them with oil.
When transferring the potatoes to a sheet pan or baking sheet, place potatoes in a single layer. Sprinkle salt and pepper. if desired.
Bake for 30 to 40 minutes or until the potatoes are browned and crisp, they should be a nice golden brown color. You may want to flip the potatoes once during cooking so all sides brown evenly. If desired just before serving you can add fresh parsley.
