A friend suggested using frozen hash browns. I think that would work as long as you squeezed all of the water out of them like I would do after shredding potatoes ( put them in a dish towel and squeeze the liquid out). I also add some grated onion and sometimes a little dill. When my parents were alive I would always make them for Christmas dinner to go along with the prime rib. We are a big carb family so we would have yorkshire pudding too. And pierogies.
