How to Make Cheesy Root Vegetable Gratin
Preheat the oven to 400°F (200°C) and grease a 3-quart baking dish with unsalted butter. The butter will help achieve a beautiful golden crust, so be generous!
Slice sweet potatoes, parsnips, and beets into very thin rounds using a mandoline for the best results. Place each type of vegetable in its own bowl, ensuring they re ready for layering.
Drizzle 4 tablespoons of cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets. Sprinkle each with grated Parmesan and fresh thyme, then season with salt and pepper, tossing until evenly coated.
Pour ¼ cup of cream into the bottom of the greased baking dish, followed by a layer of Parmesan and minced garlic. This layer will begin to infuse flavor into the bottom of the gratin.
Arrange the vegetables in layers, standing them up in bias rows until all are beautifully used. Season the top with remaining salt, pepper, and Parmesan for that lovely cheesy crust.
Cover the dish with foil and bake for 30 minutes until the vegetables are tender. Remove the foil, top with shredded Gruyère, and bake uncovered for an additional 18-20 minutes until golden brown and fork-tender.
Garnish with fresh thyme leaves before serving to add a pop of color and an aromatic touch.
Optional: Serve with a sprinkle of freshly grated nutmeg for a warm, cozy flavor.
