Ingredients for Root Vegetable Gratin with Sweet Potatoes, Parsnips, and Beets
- 1 tablespoon of softened, unsalted butter for greasing the dish
- 1 to 2 medium sweet potatoes, peeled and thinly sliced
- 3 to 4 large parsnips, trimmed and peeled
- 3 to 5 small beets, peeled and sliced into thin rounds
- 14 tablespoons of silky, rich heavy cream (divided)
- 4 ounces of finely grated Parmesan cheese, split into portions
- 1 tablespoon of freshly chopped thyme, divided, plus extra for garnish
- 1 clove of garlic, finely minced
- 1 ounce of shredded, nutty Gruyère cheese
- A pinch of sea salt, or to taste
- Freshly ground black pepper, to taste
Step-by-Step Directions
Preheat and Prep: Set your oven to 400°F (200°C). Generously coat a 3-quart baking dish with softened butter to prevent sticking, ensuring that every forkful of gratin comes out easily.
Slice the Vegetables: Using a mandoline slicer or a sharp knife, carefully cut the sweet potatoes, parsnips, and beets into thin, even rounds. Place each type of vegetable in a separate bowl to keep the colors and flavors distinct.
Coat with Cream and Seasoning: Drizzle 4 tablespoons of cream over the sweet potatoes and parsnips in their respective bowls. Pour 2 tablespoons of cream over the beets. Add 1/2 ounce of grated Parmesan cheese and 1 teaspoon of fresh thyme to each bowl, then season with salt and freshly ground black pepper, tossing until everything is evenly coated.
Prepare the Baking Dish: Pour the remaining 1/4 cup of cream into the bottom of the buttered baking dish. Sprinkle in 1/2 ounce of Parmesan cheese and scatter the minced garlic for an extra punch of flavor.
Layer the Vegetables: Arrange the vegetable slices upright in rows, alternating between sweet potatoes, parsnips, and beets. Continue layering until the dish is filled, forming an eye-catching pattern that will impress all who see it.
Bake Until Tender: Season the top of the gratin with salt, pepper, and the remaining Parmesan cheese. Cover the dish tightly with foil and bake for 30 minutes, allowing the vegetables to soften beautifully.
Add the Final Cheese Layer: Remove the foil and generously sprinkle the shredded Gruyère over the top. Return to the oven and bake uncovered for an additional 18–20 minutes until the cheese melts and turns golden brown, creating a tantalizing crust on top.
Garnish and Serve: Once baked, remove from the oven and sprinkle with fresh thyme for a final touch of brightness. Serve warm and enjoy this hearty, cheesy masterpiece with your loved ones!
