1 package Simply Potatoes
3 tablespoons butter
3 tablespoons flour
1 teaspoon salt
½ teaspoon black pepper
2¼ cups milk
¼ cup chopped onions sauteed
2 cups cheddar cheese shredded
¼ cup sour cream
4 slices bacon fried crisp and crumbled
This is what the potatoes look like:
In a small, heavy bottomed sauce pan, melt 3 tablespoons butter and add 3 tablespoons flour and simmer for about a minute; stir in the sauteed onions and crumbled bacon. Whisk in the milk (whisk quickly, at first, so you don't get lumps) and cook until the mixture thickens. When it comes to a boil, remove from heat and stir in the cheese, potatoes and sour cream. Pour into a greased 2 quart baking dish and bake at 350 for 35-45 minutes or until bubbly and potatoes are tender.
I don't see why you couldn't use frozen hash browns (as long as you thaw them first).
