Creamy sweet potatoes with a surprising kick of horseradish. It is the perfect balance of sweet and spicy for a unique side dish that pairs beautifully with roasted meats.
Place the sweet potatoes on a baking sheet and bake until easily pierced with a fork, about 1 hour.
Peel the potatoes when they are cool enough to handle and place the flesh in a stand mixer with the melted butter, horseradish sauce, and salt. Mix until smooth. Serve with additional melted butter, if desired.
