Julia Child’s Dauphinoise Potatoes
Julia Child is credited for bringing the best of French cooking to the United States. Thank goodness she did, because otherwise we all might have missed out on this truly wonderful potato dish! Julia Child's Dauphinoise Potatoes are like potatoes au gratin taken to the next level: the tender potatoes, the creamy, buttery, rich sauce, the smoky, melty cheese—all of it is as hearty, nurturing, savory, and delicious as you can imagine. When Julia Child's Dauphinoise Potatoes are on the table, mashed potatoes pale in comparison. Your weekly dinner should take a tasty visit to the French countryside!
