Yapchick (alternatively spelled Yaptzik) is a popular Jewish Passover dish of unknown origin. It’s delicious at any time of year and often served on Shabbat! The slow-baked overnight potato kugel is improved only by the delicious meat hiding on the bottom.
Preheat oven to 350 degrees Fahrenheit. Prepare a nine- x13-inch pan.
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.
