Ingredients
Vegetables
- 3 medium Yukon Gold potatoes, thinly sliced
- 2 carrots, thinly sliced
- 2 parsnips, thinly sliced
- 1 sweet potato, thinly sliced
Dairy & Cheese
- 1 cup heavy cream
- 2 cups shredded cheddar cheese
- 1 cup shredded Gruyère cheese
- Butter for greasing dish
Seasonings
- 2 cloves garlic, minced
- 1/2 tsp ground nutmeg
- 1 tsp thyme leaves
- Salt and pepper to taste
Instructions
- Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C) and generously butter a baking dish to prevent sticking and add flavor.
- Layer Vegetables: Arrange the thinly sliced root vegetables in the baking dish, alternating types to create a visually appealing pattern and even cooking.
- Prepare Cream Mixture: In a saucepan, gently warm the heavy cream along with minced garlic, ground nutmeg, thyme leaves, salt, and pepper. Heat until warm but do not allow it to boil to preserve the cream’s texture and flavors.
- Pour Cream Over Vegetables: Evenly pour the warm cream mixture over the layered root vegetables, ensuring full coverage to achieve a creamy consistency throughout the gratin.
- Add Cheese Topping: Sprinkle the shredded cheddar and Gruyère cheeses evenly over the cream-soaked vegetables to form a golden, cheesy crust.
- Bake Covered: Cover the dish with aluminum foil and bake for 40 minutes, allowing the vegetables to cook through and the flavors to meld.
- Bake Uncovered: Remove the foil and continue baking uncovered for an additional 15 to 20 minutes until the top is golden brown and bubbly, indicating the cheese has melted beautifully.
- Cool Slightly and Serve: Allow the gratin to cool for a few minutes before serving to set and make slicing easier.
Notes
- Use a mandoline slicer to achieve uniformly thin slices for even cooking and an attractive presentation.
- For a vegan alternative, substitute dairy cheese with plant-based cheese and replace heavy cream with oat milk or another dairy-free cream.
- This gratin can be prepared a day in advance and baked before serving to save time during busy gatherings.
