Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin
Step 1: Preheat and Grease
Begin by preheating your oven to 400°F (200°C). While the oven warms up, generously grease a 3-quart oval baking dish with softened unsalted butter, ensuring every inch is coated to prevent sticking. This initial step sets the foundation for your Cheesy Root Vegetable Gratin, which will bake to perfection.
Step 2: Slice the Vegetables
Carefully slice the sweet potatoes, parsnips, and beets into very thin rounds, around ⅛ inch thick. Transfer each variety of sliced vegetable into its own separate bowl to maintain their unique colors and flavors, creating an organized workspace. This will make it easier to layer them later in your gratin.
Step 3: Flavor the Veggies
To enhance the flavors of your vegetables, pour 4 tablespoons of heavy cream over the bowls of sweet potatoes and parsnips, while drizzling 2 tablespoons over the beets. Add ½ ounce of grated Parmesan and 1 teaspoon of fresh minced thyme to each bowl. Season with salt and pepper, then gently toss the vegetables to ensure they are well-coated in the creamy mixture.
Step 4: Prepare the Baking Dish
Pour the remaining ¼ cup of cream into the bottom of your prepared baking dish. Sprinkle ½ ounce of grated Parmesan over the cream, then add the minced garlic, distributing it evenly. This mixture will create a rich base for your Cheesy Root Vegetable Gratin, ensuring every layer absorbs the delightful flavors as it bakes.
Step 5: Layer the Vegetables
Start layering your vegetables in the baking dish. Begin with a layer of sweet potatoes, followed by parsnips, and then a layer of beets. Repeat this arrangement until all the vegetables are packed in, forming six vertical rows. Once finished, season the top layer with salt, pepper, and the remaining Parmesan, adding a finishing touch to your gratin.
Step 6: Cover and Bake
Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for about 30 minutes, or until the vegetables are tender when pierced with a fork. This covered baking phase helps steam the layers, ensuring they cook thoroughly while maintaining moisture—a crucial step for your Cheesy Root Vegetable Gratin.
Step 7: Add Gruyère and Finish Baking
After 30 minutes, carefully remove the foil and sprinkle the top with shredded gruyère cheese. Return the dish to the oven and bake uncovered for an additional 18-20 minutes. Look for a golden-brown top and fork-tender vegetables, signaling that your gratin is ready to shine at the dinner table.
Step 8: Garnish and Serve
Once out of the oven, garnish your Cheesy Root Vegetable Gratin with fresh thyme leaves for an added pop of color and flavor. Serve the gratin warm, allowing your guests to marvel at the vibrant layers while indulging in the comforting tastes.
