- Slice potatoes really thin, like a chip.
- Casserole dish 2” deep.
- Dice onions thin
- Vermont light sharp Cheddar cheese mixed with mild white cheddar.
- Butter (I am a serious butter-aholic. So I use 1-2 sticks of butter. I frequently make big casseroles so it depends on the amount I am making.)
Layer potatoes, salt, pepper, butter, onions, and cheese. Add another layer. You will get about 3 layers of potatoes.
Pour whole milk over it till casserole dish full.
Bake in oven at 300 for about 2 hrs.
