Step‑by‑Step Instructions for Cheesy Root Vegetable Gratin
Step 1: Preheat and Prepare the Dish
Begin by preheating your oven to 400°F (200°C). While the oven warms up, take a 3-quart baking dish and generously grease the bottom and sides with unsalted butter. This will help the Cheesy Root Vegetable Gratin release easily once baked and ensure a golden, delicious exterior.
Step 2: Slice the Vegetables
Using a mandoline for uniformity, slice the sweet potatoes, parsnips, and beets into thin rounds, around 1/8 inch thick. Aim for consistency so that all vegetables cook evenly. As you work, arrange the sliced vegetables in separate bowls for easy mixing later on, delighting in the vibrant colors that will grace your gratin.
Step 3: Coat the Vegetables
In each bowl containing the sliced vegetables, add the appropriate amounts of heavy cream and seasonings. For sweet potatoes and parsnips, mix in 4 tablespoons of cream, ½ ounce of grated Parmesan, and half of the minced thyme. For the beets, use 2 tablespoons of cream, sprinkling with salt and pepper. Toss gently to coat evenly, creating a creamy mixture.
Step 4: Assemble the Gratin Layers
Pour ¼ cup of heavy cream into the bottom of your greased baking dish, followed by sprinkling ½ ounce of Parmesan and the minced garlic. Start layering the sweet potatoes and parsnips, followed by the beets in standing rows, creating a visually stunning presentation. Continue layering until all the vegetables are placed securely in the dish.
Step 5: Season and Cover
Once your layers are beautifully arranged, season the top layer with a final sprinkle of salt and pepper. Next, cover the baking dish tightly with aluminum foil to trap moisture and steam the vegetables. Bake in your preheated oven for about 30 minutes until the vegetables are fork-tender and soft.
Step 6: Add the Cheese and Brown the Top
After 30 minutes, carefully remove the foil and sprinkle the shredded Gruyère cheese over the top of your gratin. Return the dish to the oven, uncovered, and bake for an additional 18–20 minutes. You’ll know it’s done when the cheese is melted, bubbling, and has developed a lovely golden-brown color.
Step 7: Garnish and Serve
Once baked to perfection, remove the Cheesy Root Vegetable Gratin from the oven and let it sit for a few moments. Finish with a sprinkle of fresh thyme leaves for a touch of elegance and herbal flavor. Serve warm at your holiday gathering, ready to impress your guests with this stunning, hearty side dish!

Cheesy Root Vegetable Gratin Recipe FAQs
What kind of vegetables should I use for the Cheesy Root Vegetable Gratin?
Absolutely! This recipe is wonderfully flexible.

Just ensure that any substitutes are cut to similar sizes so they cook evenly.
How long can I store the leftover Cheesy Root Vegetable Gratin?
