Ingredients

Method

Directions

  1. 1

    Prepare the Potatoes

    Preheat the oven to 375°F (190°C). Peel the russet potatoes and slice them thinly using a mandoline or sharp knife.

  2. 2

    Make the Cream Mixture

    In a medium saucepan, combine the heavy cream, horseradish, minced garlic, salt, and black pepper. Heat over medium heat until warm but not boiling.

  3. 3

    Layer the Potatoes

    In a greased baking dish, layer half of the sliced potatoes. Pour half of the cream mixture over the potatoes, then sprinkle half of the cheddar and parmesan cheese. Repeat with the remaining potatoes, cream mixture, and cheese.

  4. 4

    Bake the Gratin

    Dot the top with butter, cover with 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 bubbly.

  5. 5

    Garnish and Serve

    Remove from the oven and let cool for a few minutes. Garnish with chopped chives before serving.
