Ingredients
  

3 medium potatoes, thinly sliced

2 medium carrots, thinly sliced

1 medium parsnip, thinly sliced

1 small onion, finely chopped

2 cloves garlic, minced

1 cup heavy cream

1 cup shredded Gruyère cheese

1/2 cup grated Parmesan cheese

2 tablespoons fresh thyme leaves (or 1 tablespoon dried thyme)

Salt and pepper to taste

2 tablespoons olive oil

1 tablespoon butter (for greasing the baking dish)

Instructions
 

Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish with the butter and set aside.

    In a large skillet, heat the olive oil over medium heat. Add the chopped onion and minced garlic, sautéing until the onion is translucent (about 3-4 minutes).

      In a mixing bowl, combine the heavy cream, half of the Gruyère cheese, thyme, salt, and pepper. Stir until well combined.

        Layer the sliced potatoes, carrots, and parsnips in the greased baking dish. Begin with a layer of potatoes, followed by carrots and parsnips. Repeat these layers until all vegetables are used.

          Pour the cream mixture evenly over the layered vegetables, making sure to cover them well.

            Sprinkle the remaining Gruyère cheese and the grated Parmesan on top of the gratin.

              Cover the baking dish with aluminum foil and bake in the preheated oven for 35 minutes.

                After 35 minutes, remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown and bubbly.

                  Once cooked, let the gratin sit for about 10 minutes before serving to allow it to set.

                      - Presentation Tips: Serve the gratin hot, garnished with a sprinkle of fresh thyme leaves on top for an elegant touch. Consider serving it alongside a fresh green salad for a complete meal.
