Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin

Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While it heats up, take a moment to butter your 3-quart baking dish generously with unsalted butter, ensuring that the sides are well-coated to prevent any sticking. This step not only adds flavor but also sets the stage for your beautiful Cheesy Root Vegetable Gratin.

Step 2: Prepare the Vegetables
Wash and peel your sweet potatoes, parsnips, and beets, then slice them into thin rounds for even cooking. Keep each vegetable in a separate bowl to maintain their distinct colors and flavors. Aim for slices about 1/8 inch thick for the best results, enabling those earthy flavors to meld beautifully while baking.

Step 3: Mix the Veggies with Cream and Cheese
In a mixing bowl, toss the sweet potatoes and parsnips separately with 4 tablespoons of heavy cream each. In a separate bowl, coat the beet rounds with 2 tablespoons of cream. Sprinkle in half of the grated Parmesan cheese and minced fresh thyme, followed by a dash of salt and pepper. This mixture will deepen the flavor of your Cheesy Root Vegetable Gratin.

Step 4: Layer the Base Ingredients
Pour the remaining heavy cream into the bottom of your greased baking dish, creating a lovely base for your gratin. Next, evenly sprinkle the minced garlic and the remaining Parmesan cheese over the cream. This forms a savory foundation that will soak into the vegetables as they bake, adding to the deliciousness of the Cheesy Root Vegetable Gratin.

Step 5: Arrange the Vegetables
With precision, layer the sliced sweet potatoes, parsnips, and beets in rows, standing them upright to create a visually stunning display. Alternate the colors to enhance the presentation of the Cheesy Root Vegetable Gratin. The layering not only makes it eye-catching but also ensures even cooking, allowing each vegetable to shine in flavor.

Step 6: Bake Covered
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for about 30 minutes or until the vegetables are soft to the touch. This initial step allows the flavors to meld beautifully while keeping the veggies tender—a perfect start to your amazing Cheesy Root Vegetable Gratin.

Step 7: Add the Gruyère Topping
After 30 minutes, carefully remove the foil and check the vegetables for tenderness. Top the gratin with the shredded Gruyère cheese, evenly distributing it across the top. Return the dish to the oven for an additional 18-20 minutes, baking until the cheese is golden and bubbly—this is where the magic happens in your Cheesy Root Vegetable Gratin!

Step 8: Garnish and Serve
Once your Cheesy Root Vegetable Gratin is beautifully golden, take it out of the oven. Let it sit for a few minutes to set before serving. Just before plating, sprinkle fresh thyme over the top to add a burst of color and freshness. Serve it warm, and watch as it becomes the centerpiece of your festive gathering!
