Ingredients
  

2 medium potatoes, thinly sliced

2 medium carrots, thinly sliced

1 medium parsnip, thinly sliced

1 medium sweet potato, thinly sliced

1 onion, finely chopped

3 cloves garlic, minced

2 cups heavy cream

1 cup shredded Gruyère cheese

1 cup shredded sharp cheddar cheese

1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)

Salt and pepper to taste

2 tablespoons olive oil

¼ cup grated Parmesan cheese for topping

Instructions
 

Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish with cooking spray or a bit of olive oil.

    In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until translucent, about 3-4 minutes.

      Add the minced garlic and cook for another 1-2 minutes until fragrant. Remove from heat and set aside.

        In a large mixing bowl, combine the sliced potatoes, carrots, parsnip, and sweet potato. Add the sautéed onion and garlic mixture. Season with salt, pepper, and thyme, tossing everything to ensure even distribution.

          In a separate bowl, whisk together the heavy cream, half of the Gruyère, and cheddar cheese. Pour this mixture over the root vegetables, ensuring they are evenly coated.

            Transfer the mixture into the prepared baking dish, spreading it evenly. Top with the remaining Gruyère and cheddar cheese, and finally sprinkle the grated Parmesan on top.

              Cover the dish with aluminum foil and bake in the preheated oven for 40 minutes. Then, remove the foil and bake for an additional 15-20 minutes, or until the top is golden and bubbly, and the vegetables are tender.

                Let the gratin cool for about 10 minutes before serving, allowing the layers to set slightly.

                    - Presentation Tips: Serve the gratin hot from the oven, garnished with fresh thyme leaves for a pop of color and aroma. For an elegant touch, you can serve it in individual ramekins.
