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 the oven warms up, generously grease a 3-quart baking dish with unsalted butter, ensuring it’s well coated to prevent sticking. The buttery aroma will set a warm tone for the delightful Cheesy Root Vegetable Gratin that’s about to unfold.
Step 2: Prepare the Vegetables
Thinly slice your sweet potatoes, parsnips, and beets, aiming for uniform thickness—using a mandoline gives the best results. Transfer each type of vegetable into separate bowls to keep their flavors distinct. Their vibrant colors will shine, promising a beautiful gratin ahead, ready for seasoning.
Step 3: Season the Vegetables
To infuse flavor, coat each bowl of sliced vegetables with heavy cream, grated Parmesan, minced thyme, salt, and pepper. Stir gently until each slice is well coated. The cream will enhance the richness of your Cheesy Root Vegetable Gratin, while the herbs will add a fragrant touch to each layer.
Step 4: Layer with Cream and Garlic
Pour 1/4 cup of heavy cream into the bottom of your greased baking dish. Sprinkle this layer with minced garlic and a bit more grated Parmesan, ensuring every bite will be flavorful. This creamy foundation will help create a luscious base for your delightful layers of root vegetables.
Step 5: Arrange the Vegetables
Carefully arrange the coated vegetables in the baking dish, alternating between sweet potatoes, parsnips, and beets. Create about 6 rows with a slight bias for visual appeal, packing them snugly together. The cheerful colors will create a picturesque landscape that promises deliciousness in your Cheesy Root Vegetable Gratin.
Step 6: Bake Covered
Cover the baking dish tightly with foil and bake in the preheated oven for approximately 30 minutes. This step allows your vegetables to steam and soften, ensuring they become tender and flavorful. Keep an eye on them; they should be fork-tender but retain structure for layering.
Step 7: Uncover and Add Cheese
After 30 minutes, carefully remove the foil and sprinkle the top liberally with shredded Gruyère cheese. Return the dish to the oven uncovered for an additional 18-20 minutes. Enjoy the heavenly aroma as the cheese melts and browns, creating a golden crust that looks irresistible on your Cheesy Root Vegetable Gratin.
Step 8: Garnish and Serve
Once the top is bubbling and beautifully golden, remove the gratin from the oven. Finish with a sprinkle of fresh thyme leaves for a burst of freshness. Allow the dish to sit for a few minutes before serving, letting the layers settle, ensuring every scoop is as delightful as it looks.
