Preheat oven to 425 degrees F.
Add hash browns to large, rimmed sheet tray; the tray needs to be large enough so the hashbrowns are in a single layer with some space in between each piece of potato. Toss with oil. Add salt and pepper to taste and toss again. Spread across pan.
Place in oven for about 15 minutes until bottoms are golden brown, stirring if the outside edges are getting to brown as needed. Place back in oven for about 15 more minutes or until hash browns are mostly golden brown all over.
