Thaw frozen hash browns or pre-cook potatoes and chop into 3/8 cubes.
Mix all but the parmesan with the potatoes.
Transfer this mix to a presprayed 9X13 inch baking dish.
Sprinkle the parmesan over the top.
Bake at 350F for 60-90 minutes.
This is moist, and very flavorful. Make the whole recipe, divide it into two pans and freeze one before cooking for a quick side later. Or, double or triple it for a pot luck or office size serving. Everyone will want the recipe, and more.
