Optional Toppings

Method

Preparation

  1. 1

    Prepare the Potatoes

    Peel the potatoes and cut them into thin slices (about 2-3 mm thick). Place the slices in a bowl of cold water to prevent browning.

  2. 2

    Preheat the Oven

    Preheat your oven to 180°C (350°F).

  3. 3

    Prepare the Cream Mixture

    In a saucepan, combine the heavy cream, milk, minced garlic cloves, salt, black pepper, and fresh thyme. Heat over medium heat until just simmering, then remove from heat.

Assembling the Gratin

  1. 4

    Layer the Potatoes

    In a greased baking dish, layer half of the potato slices evenly across the bottom.

  2. 5

    Add Cream Mixture

    Pour half of the cream mixture over the first layer of potatoes. Sprinkle half of the cheddar and parmesan cheese over the top.

  3. 6

    Repeat Layers

    Repeat with the remaining potatoes, cream mixture, and cheeses, finishing with a layer of cheese on top.

Baking

  1. 7

    Bake the Gratin

    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 minutes or until the top is golden brown and bubbly.

  2. 8

    Optional Topping

    If using, sprinkle breadcrumbs and extra cheese on top for the last 10 minutes of baking for a crispy topping.

Serving

  1. 9

    Cool and Serve

    Allow the gratin to cool for 10 minutes before serving. Garnish with additional fresh thyme if desired.
