Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin

Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While the oven warms up, take your softened unsalted butter and generously grease a 3-quart oval baking dish to prevent sticking. This step is crucial for creating that perfect golden crust once your Cheesy Root Vegetable Gratin is baked to perfection.

Step 2: Slice the Vegetables
Next, slice your sweet potatoes, parsnips, and beets into very thin rounds, aiming for even thickness. To keep things organized, transfer each type of vegetable into its own bowl. These vibrant colors will not only give a beautiful presentation but will also ensure each root vegetable cooks evenly in your gratin.

Step 3: Season the Vegetables
In the bowl with sweet potatoes and parsnips, pour 4 tablespoons of heavy cream. For the beets, add 2 tablespoons of cream. Then, sprinkle in ½ ounce of grated Parmesan and 1 teaspoon of fresh minced thyme for each bowl. Generously season all the vegetables with salt and pepper, then toss until everything is well coated and fragrant.

Step 4: Create the Creamy Base
Pour the remaining ¼ cup of cream into the bottom of your prepared baking dish. Spread it evenly across the surface, and then sprinkle with an additional ½ ounce of Parmesan cheese and the minced garlic. This creamy base will add richness and flavor to your Cheesy Root Vegetable Gratin as the vegetables bake.

Step 5: Arrange the Vegetables
Now it's time to assemble! Stand the layers of vegetables in the dish at a slight diagonal, starting with sweet potatoes, followed by parsnips, and finishing with beets. Continue layering until all vegetables are used up, creating a stunning visual with six vertical rows. Season the top layer with salt, pepper, and the remaining Parmesan cheese to encourage browning.

Step 6: Bake Covered
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes, allowing the vegetables to soften and combine their flavors. This step helps retain moisture, ensuring your Cheesy Root Vegetable Gratin turns out creamy and delightful.

Step 7: Bake Uncovered
After 30 minutes, carefully remove the foil to reveal your bubbling gratin. Sprinkle shredded gruyère cheese over the top and return it to the oven uncovered. Bake for an additional 18–20 minutes or until the vegetables are fork-tender, and the top is beautifully golden brown, indicating it’s ready to be savored.

Step 8: Garnish and Serve
Once baked, remove the dish from the oven and let it cool slightly. Finish your Cheesy Root Vegetable Gratin with a sprinkle of fresh thyme leaves for a burst of color and flavor. Serve warm, and enjoy this heartwarming dish with family and friends as they relish every comforting bite.

Make Ahead Options

These Cheesy Root Vegetable Gratin are perfect for busy home cooks! You can assemble the gratin up to 24 hours in advance by layering the sliced vegetables and creamy mixture in the dish, then covering it tightly with plastic wrap. To maintain quality, refrigerate the dish until you’re ready to bake. When you’re prepared to serve, simply remove the wrap and add 5–7 extra minutes to the baking time for the delicious layers to heat through. This way, you can enjoy restaurant-quality comfort food with minimal effort, allowing more time for you to spend with your family and friends!

Cheesy Root Vegetable Gratin Recipe FAQs

How do I select the best root vegetables?
Absolutely! When choosing sweet potatoes, parsnips, and beets, look for firm vegetables without any dark spots or soft areas.

How long can I store leftover gratin?
Very! You can store any leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, simply pop it back into a 350°F oven until warmed through, preserving that delicious creaminess!

Can I freeze Cheesy Root Vegetable Gratin?
Absolutely! You can freeze the gratin before cooking for up to 3 months. Just wrap it tightly in plastic wrap and foil to prevent freezer burn. When you're ready to enjoy, transfer it to the fridge to thaw overnight, and bake it as directed. If cooking from frozen, add an extra 10-15 minutes to the bubbling-good baking time.

What’s the best way to reheat the gratin?

Can this dish accommodate dietary restrictions?
