This luxurious potato and cheese purée is a sophisticated take on classic mashed potatoes, inspired by the traditional French aligot. By combining buttery Yukon Gold potatoes with the nutty depth of Gruyère or Cantal cheese, you create a texture that is famously smooth and elastic. The addition of a lightly whipped horseradish cream topping provides a sharp, fresh contrast to the rich, savoury base, making it an exceptional vegetarian side dish for any special occasion.
Ideal for autumn gatherings or as a comforting accompaniment to a Sunday roast, this recipe relies on a potato ricer to achieve its signature velvet-like consistency. The gratin-style finish under the grill adds a beautiful golden colour and a gentle heat from the horseradish. Serve this indulgent mash alongside roasted root vegetables or a crisp green salad for a balanced and satisfying homemade meal.

Ingredients for Potato-and-Cheese Purée
900g Yukon Gold potatoes (6 medium)
4 garlic cloves
1 1/4 teaspoons salt
3 tablespoons unsalted butter, softened
180ml whole milk
350g Cantal or Gruyère cheese, coarsely grated on large holes of a box grater (750g )
1/2 teaspoons black pepper
160ml chilled double cream
2 tablespoons drained bottled horseradish
a potato ricer or a food mill fitted with medium disk
1 (2-quart) ceramic or metal shallow baking dish or 6 (1-cup) shallow gratin dishes
How to make Potato-and-Cheese Purée
Cover potatoes with salted water > by 2 inches in a 4- to 5-quart heavy pot and simmer until very tender, about 40 minutes. Drain in a colander.
Mince garlic and mash to a paste with 1 teaspoon salt using side of a large heavy knife.
When potatoes are cool enough to handle when held in a kitchen towel, peel and force through ricer into cleaned saucepan. Add butter, garlic paste, and milk and cook over moderately low heat, stirring vigorously with a wooden spoon, until fluffy and heated through, about 2 minutes. Add cheese and pepper and cook, stirring vigorously with a heatproof rubber spatula or wooden spoon, until cheese is melted, smooth, and almost taffylike, about 10 minutes.
Preheat grill. Butter baking dish. (If using 6 individual gratin dishes, butter and put on a baking sheet.)
Transfer potato mixture to baking dish, smoothing top.
Beat cream in a bowl with an electric mixer until it holds soft peaks, then beat in horseradish and remaining 1/4 teaspoons salt. Spread horseradish cream over potato mixture and grill 4 to 5 inches from heat, rotating gratin if it isn't browning evenly, until golden, 1 to 2 minutes.
