Insert shredding disc; peel potatoes and shred; you should have 4 cups.
Transfer potatoes to a bowl and cover with water to prevent discoloration.
Change to metal blade.

With motor running, pour hot milk mixture slowly through the feed tube.
Drain potatoes well by pouring into a colander and pressing out the liquid.
Combine potatoes, onion, and egg mixture.
Rub the remaining 1 tablespoon butter over the sides and bottom of an 8-inch square baking pan.
Spoon potato mixture into pan and sprinkle with paprika.
Bake, uncovered, in a 375° oven until set in center and edges are browned and crusty (about 50 minutes).
Cut in squares to serve.
