6 cups peeled and diced potatoes, cooked until barely tender
1/2 cup milk
2 tbsp dried onion flakes
Preheat oven to 350 degrees. Put half of the potatoes in a 2-quart casserole dish. Pour 1/2 the sour cream and milk over the potatoes. Sprinkle with salt and pepper. Add half the onion flakes. Repeat the process. Garnish with some dried parsley flakes or fresh chives, if desired for color. Bake 25 to 30 minutes at 350 degrees.
