How to Make Cheesy Root Vegetable Gratin
-
Preheat your oven to 400°F (200°C). Grease a 3-quart baking dish with unsalted butter, ensuring every corner is covered to enhance flavor and prevent sticking.
-
Slice sweet potatoes, parsnips, and beets into very thin rounds, ideally using a mandoline for uniform thickness. Transfer each vegetable into separate bowls for easy mixing.
-
Pour 4 tablespoons of heavy cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets. Add half an ounce of grated Parmesan and 1 teaspoon of minced thyme to each bowl. Season generously with salt and pepper, and toss until evenly coated.
-
Spread 1/4 cup of cream at the bottom of the greased baking dish. Sprinkle with half an ounce of Parmesan and add the minced garlic, enhancing the sauce’s flavor.
-
Layer the vegetables in the dish: start with the sweet potatoes, followed by the parsnips, and finally the beets to create six colorful rows.
-
Season the top layer with salt, pepper, and the remaining Parmesan. Cover the dish with foil and bake it for 30 minutes, or until the vegetables are soft and tender.

Uncover the dish, and top with shredded Gruyère cheese. Bake for an additional 18-20 minutes until the cheese is deliciously melted and golden brown.

Expert Tips for Cheesy Root Vegetable Gratin
-
Prep Ahead: Spend a little time preparing the dish a day early. Wrap it tightly in foil to meld flavors and save time on the day of serving.
-
Slicing Technique: Use a mandoline for perfectly even slices. Uneven cuts can lead to some vegetables overcooking while others may remain too firm.
-
Layering Magic: Properly layer the vegetables to ensure even cooking and flavor distribution. Begin with sweet potatoes and build up with parsnips and beets for a vibrant presentation.
-
Creamy Consistency: Don’t drown the beets in cream! A light coating prevents color bleed while keeping them from overpowering the dish’s overall flavor.
-
Cheese Variations: Feel free to experiment with different cheeses. Feta or goat cheese can add a unique twist to your Cheesy Root Vegetable Gratin if you’re looking for something different.
Each of these tips will help you create the best version of your Cheesy Root Vegetable Gratin, impressing everyone at your next gathering!

Cheesy Root Vegetable Gratin Recipe FAQs
What is the best way to choose root vegetables for the Cheesy Root Vegetable Gratin?
Absolutely! When selecting root vegetables, look for those that are firm, with no dark spots or blemishes. Choose sweet potatoes that are smooth and even in shape. The parsnips should be firm and creamy white or pale yellow, and the beets should be small with a deep, rich color. Size matters, as larger root vegetables can be tougher and may not cook as evenly.
How should I store leftovers of the Cheesy Root Vegetable Gratin?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply preheat your oven to 350°F (175°C) and cover the gratin with foil to keep it moist. Bake for about 25 minutes or until heated through, and feel free to add a splash of cream or a sprinkle of cheese to revive that delicious creaminess!
Can I freeze Cheesy Root Vegetable Gratin?
Yes, freezing is a great option! To freeze, prepare the dish up to the baking stage, then wrap it securely in foil or plastic wrap. It’ll keep well in the freezer for up to 2 months. Thaw overnight in the refrigerator before baking. To bake, preheat your oven to 400°F (200°C) and bake for about 50–60 minutes, or until bubbly and golden on top.
What should I do if my gratin is watery?
Very! If you find your gratin is watery after baking, it might be due to excess moisture in the vegetables. To fix this, next time, try to pat the sliced vegetables dry with a paper towel before mixing them with cream. Additionally, cooking the gratin longer while uncovered can help evaporate some of the excess liquid, resulting in a creamier texture.
Is this recipe suitable for someone with dairy allergies?
While this Cheesy Root Vegetable Gratin contains dairy, there are alternatives! Use dairy-free cream in place of heavy cream and substitute vegan cheeses or nutritional yeast for the cheese. This way, you can still enjoy a delicious gratin that aligns with dietary restrictions. Always double-check your ingredients if cooking for someone with allergies!
Can I prepare the Cheesy Root Vegetable Gratin in advance?
Absolutely! In fact, making this dish one day ahead can enhance its flavor. Just prepare, cover tightly with foil, and refrigerate. On the day you plan to serve it, simply pop it into the oven after letting it sit at room temperature for about 30 minutes. This process allows the flavors to meld beautifully, making your holiday feast even more delightful!
