Preheat oven to 350 degrees Fahrenheit. Prepare a nine- x13-inch pan.

Place meat into prepared pan. Set aside.

Using a food processor fitted with the thin shredder blade or kugel blade, shred potato and onion. Add eggs. Add salt and pepper; pour mixture over the meat.

Bake for one and a half hours; then reduce oven temperature to 200 degrees Fahrenheit. Pour water over kugel, cover tightly with foil, and bake for 12 to 16 hours, or until ready to serve.
