Potato kugel gratin is a traditional Jewish dish that combines the flavors of a classic potato kugel and a creamy gratin. It is made by layering thinly sliced potatoes with a mixture of eggs, cream, and cheese, then baking it until golden and bubbly. The result is a rich and comforting side dish that pairs well with roasted meats or can be enjoyed on its own. The crispy top layer and tender, creamy interior make this potato kugel gratin a crowd-pleasing favorite.
