  • 500g mixed root vegetables (such as potatoes, parsnips, carrots, and turnips)
  • 300ml double cream
  • Two garlic cloves, crushed
  • One bay leaf
  • A handful of fresh thyme leaves
  • Salt and freshly ground black pepper
  • 50g grated Gruyère cheese
  • 25g grated Parmesan cheese
  • Butter, for greasing


  1. Preheat the oven to 180°C (350°F). Grease a baking dish with butter, ensuring that it is well-coated to prevent sticking.
  2. Peel the root vegetables and slice them thinly using a mandoline or sharp knife. Aim for uniform thickness to ensure even cooking.
  3. In a saucepan, combine the double cream, crushed garlic cloves, bay leaf, and fresh thyme leaves. Season with salt and freshly ground black pepper to taste. Heat the mixture over medium heat until it begins to simmer, then remove from heat and let it infuse for 10 minutes to allow the flavors to meld.
  4. Arrange the sliced root vegetables in the prepared baking dish, layering them evenly to create a visually appealing pattern. Pour the infused cream mixture over the vegetables, ensuring that they are fully submerged.
  5. Sprinkle the grated Gruyère and Parmesan cheese over the top of the gratin, covering it evenly to form a golden crust as it bakes.
  6. Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 45 minutes, then remove the foil and continue baking for an additional 15-20 minutes or until the gratin is golden brown and bubbling.
  7. Once cooked, remove the gratin from the oven and let it rest for a few minutes before serving. This allows the flavors to meld and the dish to set slightly, making it easier to portion.
  8. Serve the root vegetable gratin hot, garnished with additional fresh thyme leaves if desired. Enjoy the creamy richness and comforting flavors of this decadent dish.
