Preheat the oven to 350 degrees F.

Bring a large pot of water to a boil over high heat. Add 1 teaspoon of salt and the potatoes. Cook the potatoes until tender, then drain and cool to room temperature. Add the potatoes and the remaining ingredients to a blender and puree.

Pour into a greased 9 by 13-inch casserole pan and bake in the oven for 1 hour or until set and lightly browned. Remove from the oven and serve hot.
