Duchess Baked Potatoes

These Duchess baked potatoes offer a sophisticated twist on classic mashed potatoes, bringing an air of elegance to your dinner table. By combining buttery Yukon Gold potatoes with a rich blend of double cream, soured cream and egg yolks, you create a texture that is impossibly silky. The garlic and crushed peppercorns provide a subtle, savoury depth, while the decorative peaks on the surface crisp up beautifully in the oven to provide a golden, textural contrast.

As a versatile vegetarian side dish, this bake is perfect for a festive roast or a special Sunday lunch. The recipe is wonderfully practical for entertaining, as it can be assembled a day in advance and kept in the fridge. Simply slide the dish into the oven whenever you are ready to serve a crowd-pleasing accompaniment that looks just as good as it tastes.

Ingredients for Duchess Baked Potatoes

  • 12 medium Yukon Gold potatoes (3 1/2–1.8kg )

  • Kosher salt

  • 5 large egg yolks

  • 2 garlic cloves, finely grated

  • 300ml double cream

  • 180ml soured cream

  • 10 tablespoons unsalted butter, melted

  • 1 teaspoon pink or black peppercorns, finely ground

Place potatoes in a large pot and pour in water to cover by 2"; season with salt. Bring to a boil over medium-high. Reduce heat and simmer until a paring knife very easily slides through potatoes, 25–35 minutes. Drain and let cool slightly.

Preheat oven to 218°C. Whisk egg yolks, garlic, cream, soured cream, butter, and peppercorns in a large bowl; season generously with salt. Peel potatoes and pass flesh through a ricer or a food mill (or mash them by hand if you don’t mind a few lumps) directly into bowl with egg mixture. Fold in gently (be careful not to overmix). Transfer to a 3-quart baking dish and decoratively shingle or swirl surface. Bake, rotating once, until golden brown and slightly puffed, 30–40 minutes.

Dish can be assembled 1 day ahead. Cover and chill. Increase bake time by 5–10 minutes.
