2 Tablespoons butter 2 cups milk
2 Tablespoons flour 4-5 medium russet potatoes, peeled and sliced
1 teaspoon salt
Preheat oven to 350 degrees. Lightly grease bottom of large casserole dish with butter.
Melt the 2 tablespoons of butter in a large saucepan. Whisk in flour until thoroughly blended. Add salt. Slowly add milk while whisking constantly. Stir frequently with whisk on bottom of pan until sauce boils and thickens. Add potatoes and heat until it boils again, stirring often with spoon.
Pour potatoes into prepared casserole dish. Bake for 1 hour at 350 degrees fahrenheit. If you want the tops of the potatoes to brown bake uncovered. For white creamy potatoes bake covered.
To make Au Gratin Potatoes stir one cup of shredded cheese into the sauce just before adding the potatoes.
Scalloped potatoes are easy to make and go well with any meat.
