This simple recipe for hash brown potatoes is made from shredded potatoes that are cooked in hot butter and oil until crispy, and then salted and peppered to taste. They can be prepared on a griddle or a skillet and enjoyed not just for breakfast but with any meal. Russet potatoes, also known as idaho potatoes, are used here because they have a low-moisture and high-starch content, making them ideal for frying. The trick is to boil the potatoes until they are still a little al dente otherwise, when you grate them, they will turn to mush.
