These horseradish mashed potatoes offer a sophisticated, heart-healthy twist on a classic British side dish. By swapping traditional butter and cream for high-quality extra-virgin olive oil and a splash of the potato cooking water, you achieve a wonderfully smooth, light texture without the saturated fat. The addition of prepared horseradish provides a subtle heat and a punchy depth of flavour that cuts through the richness of any main course.

How to make Horseradish Mashed Potatoes
Cook potatoes in large saucepan of boiling salted water until tender, about 20 minutes. Drain, reserving 240ml cooking liquid. Place in large microwave-safe bowl. Add 45ml oil. Mash until potatoes are smooth, adding remaining 1 tablespoon oil, if desired, and reserved cooking liquid by 60ml fuls to moisten to desired consistency. Mix in horseradish. Season to taste with salt and pepper. DO AHEAD: Potatoes can be made up to 2 hours ahead. Let stand at room temperature. Rewarm potatoes in microwave before continuing.
Transfer potatoes to bowl and serve.
