For an extra layer of flavor, consider adding a sprinkle of shredded cheddar cheese or a dash of hot sauce to the filling. Feel free to substitute your favorite breakfast meats, such as sausage or ham, for the bacon. If you're short on time, pre-shredded cheese and pre-cooked bacon can be used. To prevent the bottom of the pastry from becoming soggy, ensure the hash browns are well-drained and not overly greasy. These pastries can be assembled ahead of time and refrigerated until ready to bake. Add a few minutes to the baking time if baking from cold.
