Mary Berry’s version of Dauphinoise Potatoes follows the traditional French technique of layering thinly sliced potatoes in a creamy garlic-infused sauce. What sets this version apart is its simplicity, focusing on high-quality ingredients to bring out the natural flavors of the potatoes. The dish is slow-baked until the cream thickens and the potatoes become tender, with a golden, slightly crispy top. It’s a timeless side dish, perfect for special occasions or a hearty Sunday roast.
