Recipe Ingredients
Hash browns – Stacking hash brown patties works well, or choose between shredded, diced or country-style potatoes.
Heavy whipping cream – The high fat content in cream will help attain a delicious cassserole but simply decrease the amount of butter used in the recipe by half and/or replace whipping cream with milk to slim the recipe down.
Seasoning salt – Lawry’s seasoned salt is my go to seasoning for these potatoes but use any blend that is on hand, especially if you want to lower the sodium intake.

FAQ About Hash Browns
You want to use a starchy potato for making hash browns and avoid red potatoes that have a higher moisture content, so they won’t crisp up like other potatoes.
There are a couple of things to do to help hash browns to stick together. When you slice your own potatoes, you can soak the potatoes to remove some of the excess starch. Whether you soak them or not, don’t skip removing the excess water from the potatoes by taking some paper towels to dry them. A binding agent, like an egg can also help to keep the potatoes to fry together.
Due to the amount of butter used in the recipe as well as the heavy whipping cream, it is not considered a “healthy” recipe. However, you can slim down the recipe quite a bit by decreasing the amount of butter used by half and/or replace whipping cream with skim milk.
Because this recipe contains dairy in the form of heavy whipping cream, I do not recommend you freeze it unbaked. Prepare the dish, then allow it to cool completely before freezing. Wrap pan in plastic wrap and/or foil to keep the air out. When you are ready to serve your dish, allow the baking dish to come to room temperature, then bake as directed.
When you cut your own potatoes, soaking hash browns in water helps to remove the excess starch and keep them from turning an unappetizing color.
