Cooking Instructions

  1. 1

    Prepare the potatoes

    Preheat your oven to 375°F (190°C). Peel the russet potatoes and slice them thinly (about 1/8 inch thick).

  2. 2

    Make the horseradish cream mixture

    In a mixing bowl, combine the heavy cream, prepared horseradish, minced garlic, salt, and black pepper. Mix well.

  3. 3

    Layer the potatoes

    Grease a 9x13-inch baking dish with butter. Layer half of the sliced potatoes in the bottom of the dish. Pour half of the horseradish cream mixture over the potatoes. Sprinkle half of the cheddar and half of the Parmesan cheese on top.

  4. 4

    Finish layering

    Repeat the layers with the remaining potatoes, cream mixture, cheddar, and Parmesan cheese.

  5. 5

    Bake

    Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender.

  6. 6

    Garnish and serve

    Remove from the oven, let it sit for a few minutes, then garnish with chopped chives before serving.
