Whipped Potatoes with Horseradish

This indulgent vegetarian side dish reimagines classic mashed potatoes with a sophisticated twist. By whipping the potatoes with an electric mixer, you achieve a remarkably light and airy texture that feels far more special than your everyday mash. The addition of tangy cream cheese and a hint of fiery horseradish provides a wonderful depth of flavour, while the spring onions offer a fresh, savoury crunch in every mouthful.

Perfect for a festive gathering or a comforting Sunday roast, these whipped potatoes can be prepared a day in advance to save you time in the kitchen. The final flourish of melted butter and paprika creates a beautiful golden crust in the oven. Serve alongside a rich nut roast or slow-cooked beef to soak up all the delicious juices.

Ingredients for Whipped Potatoes with Horseradish

  • 2 tablespoons unsalted butter, melted, divided, plus 120ml (1 stick), cut into 1" cubes, room temperature

  • 1.1kg russet potatoes, peeled, cut into 2" pieces

  • Kosher salt

  • 110g cream cheese, cut into 1" cubes, room temperature

  • 2 tablespoons prepared horseradish

  • 160ml whole milk, warmed

  • Freshly ground black pepper

  • 1 bunch spring onions, white and pale-green parts only, minced (about 100g loosely packed)

  • Hungarian sweet paprika

Brush an 8x8x2" or other 6-cup baking dish with 1 tablespoon melted butter. Place potatoes in a large pot and add cold water to cover by 1". Add a large pinch of salt; bring to a boil, then reduce heat to medium-low. Cover with lid slightly ajar and gently simmer until potatoes are tender, about 20 minutes.

Drain potatoes; return to same pot. Shake and stir with a wooden spoon over very low heat until dry. Then, using a potato masher, mash coarsely. Using a hand mixer, beat 110g butter into potatoes, a few pieces at a time, until blended. Beat in cream cheese, adding a few pieces at a time, then horseradish. With motor running, gradually add milk, beating until potatoes are light and fluffy, 4-5 minutes. Season well with salt and pepper.

Stir in spring onions. Scrape potatoes into prepared dish.3 Use a spatula to create peaks across the surface. Drizzle potatoes with remaining 1 tablespoon melted butter and sprinkle with paprika. DO AHEAD: Potatoes can be made 1 day ahead. Let stand at room temperature to cool. Cover and chill.

Preheat oven to 177°C. Bake potatoes, uncovered, until they are heated through and top is golden, about 40 minutes (if chilled, add 10 minutes).
