This vegetarian side dish elevates the humble spud into a sophisticated centrepiece. Luxe French potatoes combine the silky texture of traditional pomme purée with a rich, stretchy blend of Gruyère and mozzarella cheese. Infused with aromatic garlic and a hint of nutmeg, the base is incredibly indulgent, while the piped rosettes on top provide a beautiful, golden finish that is sure to impress guests at any dinner party.
Ideal for a Sunday roast or a festive celebration, these potatoes offer a more refined alternative to a standard gratin or mash.

How to make Luxe French Potatoes
Back to contentsPlace rack in middle of oven and preheat to 177°C. Place potatoes in a large wide heavy pot. Add 1 1/2 teaspoons salt and enough cold water to cover by 2". Bring to a boil over high heat, then reduce heat to medium-low and simmer until potatoes break apart when pierced with the tip of a knife, 35–40 minutes.
Meanwhile, cook garlic, cream, and butter in a medium saucepan over medium heat, whisking occasionally, until butter is melted. Whisk in nutmeg, pepper, and 1 tablespoon plus 1 teaspoon salt. Remove from heat.
Drain potatoes and immediately pass through potato ricer into a large bowl. Stir in cream mixture until smooth.
Return half of potato mixture to wide pot; reserve remaining potato mixture in bowl. Add Gruyère and mozzarella and cook over low heat, stirring constantly with a wooden spoon, until cheese is melted and mixture can be stretched with the spoon (like warm mozzarella), about 10 minutes. Transfer to gratin dish; smooth top.
Working in batches if needed, spoon reserved potato mixture in bowl into pastry bag fitted with star tip. Pipe very tight rows of 1/2x1/2" rosettes on potato-cheese mixture in gratin dish. Bake until top is golden brown, about 45 minutes. Let stand 10 minutes before serving.
