How to Make Cheesy Root Vegetable Gratin
Step 1: Preheat Your Oven
Start by preheating your oven to 400˚F. This ensures that your gratin bakes evenly throughout. While it’s warming up, grease a 3-quart baking dish with softened butter; this will help prevent sticking and add a lovely richness.
Step 2: Slice Your Vegetables
Next, slice your sweet potatoes, parsnips, and beets into very thin rounds. Using a mandoline makes this step quick and easy! Transfer each vegetable into its own bowl so we can individually coat them with cream and cheese later.
Step 3: Coat the Vegetables
Pour 4 tablespoons of heavy cream over each bowl of sweet potatoes and parsnips, while adding 2 tablespoons over the beets. Then sprinkle each bowl with ½ ounce of grated Parmesan cheese and 1 teaspoon of minced thyme. Season generously with salt and pepper before tossing everything together until well coated—this will ensure every bite is flavorful!
Step 4: Assemble in Baking Dish
Pour the remaining quarter cup of cream into the bottom of your greased baking dish. Sprinkle with another ½ ounce of Parmesan cheese along with minced garlic for an aromatic base. Now it’s time to layer! Start stacking sweet potatoes at one end, followed by parsnips, then beets. Keep repeating until you’ve created beautiful rows—aim for about six layers!
Step 5: Bake Covered
Once assembled, season the top layer generously with salt, pepper, and sprinkle on any remaining Parmesan cheese. Cover your baking dish tightly with foil and bake for about 30 minutes until those lovely vegetables are soft.
Step 6: Add Gruyere Cheese & Bake Again
After half an hour has passed, carefully uncover the gratin and top it off with shredded gruyere cheese. Pop it back into the oven uncovered for another 18 to 20 minutes until everything is tender and beautifully golden brown on top.
Step 7: Garnish & Serve
Finally, sprinkle some fresh thyme leaves on top before serving! This adds not only color but also an extra layer of flavor that will make your guests swoon.
And there you have it—a delicious Cheesy Root Vegetable Gratin that’s sure to become a favorite at your table! Enjoy every cheesy bite!

- Layer Wisely: Alternate the layers of sweet potatoes, parsnips, and beets. This not only creates a beautiful presentation but also allows the flavors to meld together beautifully as they bake.
- Don’t Skimp on Seasoning: Generously season each layer of vegetables with salt and pepper. This enhances the natural sweetness of the root vegetables and infuses them with flavor.
