Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin
Step 1: Preheat and Prepare the Dish
Preheat your oven to 400°F (200°C) and grab a 3-quart oval baking dish. Grease the dish with 1 tablespoon of softened unsalted butter, ensuring every corner is covered. This will create a non-stick surface and add a touch of flavor to your Cheesy Root Vegetable Gratin!
Step 2: Slice the Vegetables
Using a sharp knife or a mandoline, slice the sweet potatoes, parsnips, and beets into very thin rounds, aiming for uniform thickness. This not only ensures even cooking but also looks stunning in the dish. Transfer each type of vegetable into its own bowl for easy mixing and layering later on.
Step 3: Coat the Vegetables
In the respective bowls, pour 4 tablespoons of heavy cream over the sweet potatoes and parsnips, and drizzle 2 tablespoons over the beets. Add ½ ounce of grated Parmesan and 1 teaspoon of minced thyme to each bowl. Season with salt and pepper, then toss gently until the vegetables are well coated in the creamy mixture.
Step 4: Set the Base
Pour the remaining ¼ cup of heavy cream into the bottom of your prepared baking dish, creating a creamy base for the Cheesy Root Vegetable Gratin. Sprinkle with ½ ounce of Parmesan and the minced garlic. This base will enhance the flavors and keep the bottom layer moist during baking.
Step 5: Layer the Vegetables
Begin layering the vegetables in the baking dish, starting with the sweet potatoes first. Follow with a layer of parsnips, then beets, repeating the process until all vegetables are used up and you’ve formed six vertical rows. Finish the top layer with a sprinkle of salt, pepper, and the rest of the grated Parmesan for a beautiful finish.
Step 6: Bake Covered
Cover the baking dish tightly with aluminum foil, which will trap steam and help the vegetables cook evenly. Bake in the preheated oven for 30 minutes, or until the vegetables look tender when pierced with a fork. This will set the foundation for the creamy layers of the gratin.
Step 7: Add the Gruyère and Finish Baking
After 30 minutes, carefully remove the foil and sprinkle 1 ounce of shredded gruyère evenly over the top of the vegetables. Return the dish to the oven and bake uncovered for an additional 18-20 minutes. You’ll know it’s done when the top is lightly browned and the vegetables are fork-tender, creating that irresistible cheesy crust.
Step 8: Garnish and Serve
Once baked, remove the Cheesy Root Vegetable Gratin from the oven and let it sit for a few minutes. Finish with a sprinkle of fresh thyme leaves to bring a burst of flavor. Serve warm, and marvel at how this comforting dish transforms simple root vegetables into an elegant centerpiece for your table!
