Start with potatoes and an onion
I grate all this with my Cuisinart food processor
Ready for the oven
Ready to serve
1/4 cup butter
1/4 cup flour
4 cups milk
2 tsp salt
pepper, to taste
1 large onion, finely chopped
7 large potatoes (about 6 cups grated)
Melt butter and stir in flour over low heat. Slowly begin stirring in the milk, blending well. Bring to a boil and cook one minute, stirring constantly. Season with salt & pepper.
Mix the onions and grated potatoes in a large bowl and pour the white sauce over. Turn to mix. Then pour into a greased jelly roll pan and bake @ 300°F for about 2 1/2 to 3 hours.
1. The original recipe suggested this as a side for ham, but it is also great with bbq chicken, grilled salmon, etc. It also is a good potato dish for breakfast.
2. I grate the potatoes lengthwise in my processor, so there are long shreds.
