Notes from Bonnie:
When I make the recipe, I make a few changes. I don't use the cracker crumbs and I use 2 cups of cheese instead of one. I use the OreIda Southern Style Potatoes brand of hash browns. I also melt my butter down instead of just softening it. The trick is making sure that the potatoes are not crunchy but nice and soft. I try to get the potatoes out of the freezer ahead of time for at least an hour. If they still need to thaw before I use them in the recipe, I just pop them in the microwave for a few minutes. And if I have time, I like to let the casserole cook for a full hour.
