8 lg red potatoes – thin sliced ( 1/4 inch ) i used my mandolin
4 Tbsp heaping, flour
3 1/2 c heavy cream
1 1/2 c milk
2 onion, sliced thin
salt & pepper
1 stick butter, cut into 8 pieces
1. Preheat oven to 400 degree F. Spray a large deep baking pan with cooking spray ( I used my turkey roaster or deep lasagna pan.) In a large bowl, mix cream, milk and flour with a whisk until flour in incorporated. Set aside Stagger 1/4 of potatoes in the bottom of pan. Liberally salt pepper and sprinkle 1/4 of onion over layer. Pour 1/4 milk mixture evenly over layer. Place 1/2 butter pats evenly over this layer and top layer. Repeat 3 more times. Cover with foil and bake until potatoes are tender. I then removed the foil and bake 20 minutes longer to brown the top. Enjoy!
2. The baking time will depend on how thick you slice your potatoes.
