4-6 potatoes, baked in foil and chilled overnight, then peeled and grated
2-4 tablespoons, scallions or green onions, chopped
1-2 cups cheddar cheese, grated
1-2 cups sour cream
lots of salt and pepper
Combine everything and put into a greased casserole dish. Bake at 350° for 30 minutes.
That's it! It was very good. I think we'll stick with our regular recipe, though, because it adds butter and cream of mushroom soup, which is just more deliciousness, and cuts down on the tang of the sour cream. Also, I've always boiled my potatoes before grating them; it was nice to learn that this casserole works just fine with baked potatoes as well.
