Cheesy Root Vegetable Gratin
- Total Time: 65 mins
- Yield: 8 1x
Description
This beautiful Cheesy Root Vegetable Gratin is as beautiful as it is tasty. Sweet Potatoes, beets, and parsnips with cream and garlic baked to perfection. We love this side dish for special occasions like Thanksgiving.
Ingredients
- 1 tablespoon unsalted butter (softened)
- 1–2 long sweet potatoes (about 2 inches thick), peeled
- 3–4 large parsnips, ends trimmed and peeled
- 3–5 small beets, peeled
- 14 tablespoons heavy cream, divided ((whole milk is fine, but mixture won't thicken as much or be as creamy))
- 4 ounces grated Parmesan, divided
- 1 tablespoon fresh minced thyme, divided (plus more for garnish)
- 1 garlic clove, minced
- 1 ounce shredded gruyere
- salt and pepper to taste
Instructions
- Preheat oven to 400˚F. Grease a 3 quart baking dish with butter.
- Slice sweet potato, parsnips and beets into very thin rounds (using a mandoline is easiest) and transfer each vegetable to its own bowl.
- Pour 4 tablespoons cream over each sweet potatoes and parsnips, and 2 tablespoons cream over beets. Top each bowl of sliced vegetables with ½ ounce grated Parmesan and 1 teaspoon minced thyme. Season each bowl generously with salt and pepper and toss together until all vegetable slices are well coated.
- Pour remaining 1/4 cup cream into the bottom of a 3 quart (oval) baking dish and sprinkle with ½ ounce of Parmesan and minced garlic.
- Grab a stack of sweet potatoes and line them standing up on a bias, at the top of the baking dish. Follow the sweet potato with a row of parsnips, followed by a row of beets. Repeat with the remaining sweet potatoes, parsnips and beets, creating 6 rows of root vegetables.
- Season top of gratin with salt, pepper and sprinkle of remaining Parmesan.
- Cover with foil and bake for 30 minutes or until vegetables are soft.
- Uncover gratin and top with shredded gruyere.
- Place gratin back into oven, uncovered, and continue to bake for an additional 18 to 20 minutes or until vegetables are fork tender, cheese has melted and the top has lightly browned.
- Finish with a sprinkle of fresh thyme leaves. Serve.
Notes
Use a mandoline for even vegetable slices. Whole milk can substitute for heavy cream but results will be less creamy. The gratin is done when vegetables are fork tender and top is lightly browned. Store leftovers covered in refrigerator for up to 3 days.

How to Prepare This Dish
Steps and time-saving tips
First, preheat your oven to 375°F and generously grease your baking dish. Meanwhile, grab your mandoline slicer to uniformly slice all your root vegetables; this crucial step ensures everything cooks evenly and saves you significant prep time. Next, whisk together your cream, garlic, and all your seasonings in a large bowl. Then, toss your vegetable slices in this creamy mixture until they are fully coated. Now, begin layering the vegetables in your prepared dish, slightly overlapping them in neat rows. After that, pour any remaining cream mixture over the top and tightly cover your dish with foil. Bake the gratin covered for about 40 minutes. Subsequently, remove the foil, sprinkle on a generous amount of cheese, and continue baking for another 20 to 25 minutes until the top is golden and bubbly. Finally, let the dish rest for 10 minutes before serving; this allows the sauce to thicken perfectly. For a golden-brown finish, briefly broil the Cheesy Root Vegetable Gratin | Spoon Fork Bacon at the very end.
I have absolutely learned the hard way that uneven slicing is the enemy of a perfect gratin. Initially, I would hand-cut my vegetables, which resulted in some pieces being mushy while others were still crunchy. Investing in a simple mandoline slicer changed everything for me, ensuring every slice bakes at the same rate. Another classic mistake I made was skipping the rest time after baking; I’d serve it immediately, only to have a soupy, loose sauce on my plate. Now, I always let my Cheesy Root Vegetable Gratin | Spoon Fork Bacon rest, which gives the sauce time to set beautifully.

Cultural Connection and Variations
Where this recipe comes from
The story of the gratin is a humble one, born from the necessity of European farmhouse kitchens to create something luxurious from simple, earthy ingredients. Traditionally, this dish was a way for families to use their root cellar’s bounty during the long winter months. Cooks would thinly slice potatoes or other hardy vegetables, layer them with cream and cheese, and bake them until golden and bubbly. This method transformed basic staples into a comforting, shareable centerpiece.
While the French Dauphi
noise is famously rich with potatoes and cream, and the Swiss Rösti offers a crisper, pancake-like take, the spirit remains the same. It is about warmth, community, and nourishment. Our version, the Cheesy Root Vegetable Gratin | Spoon Fork Bacon, honors that tradition by celebrating a medley of roots like parsnips, sweet potatoes, and turnips. This approach creates a more complex flavor profile and a beautiful mosaic of color in every slice. The heart of the Cheesy Root Vegetable Gratin | Spoon Fork Bacon is this beautiful fusion of old-world technique and a modern, vibrant mix of produce.How it fits in today’s cooking
This classic casserole has secured its place in contemporary cooking because it is incredibly versatile. It shines as a make-ahead holiday side dish that feeds a crowd, but it’s also hearty enough to be a simple weeknight vegetarian main with a green salad. Modern home cooks are constantly reimagining the gratin, often by experimenting with different vegetable combinations based on what’s fresh and local.
You can easily adapt the recipe to fit various dietary needs, perhaps by using a gluten-free flour for the roux or a plant-based cream alternative. For a lighter take, some forgo the flour-thickened sauce altogether, opting instead to simply layer the vegetables with broth, herbs, and a modest amount of cheese. If you’re looking for another vegetable-forward side dish that’s perfect for any gathering, our Roasted Brussels Sprouts with Balsamic is a fantastic option. And when you need the perfect protein to pair with your gratin, this Herb Crusted Pork Tenderloin creates a truly unforgettable meal.
Taste and Texture
What makes it delicious
This Cheesy Root Vegetable Gratin | Spoon Fork Bacon delivers a deeply satisfying and complex experience. You first encounter a crisp, golden-brown crust that shatters delicately under your fork, revealing the tender, creamy layers beneath. Each bite is a rich and savory symphony because the nutty, sharp Gruyère cheese melts into a velvety sauce that clings to every slice of earthy sweet potato and parsnip. The aroma is utterly intoxicating as fragrant thyme and a hint of garlic waft from the oven, promising the comfort within. Although the vegetables become meltingly soft, they still retain a slight bite so the texture never becomes mushy. The overall sensation is one of hearty indulgence where the creamy elements perfectly balance the crisp top and the tender vegetable foundation. This Cheesy Root Vegetable Gratin | Spoon Fork Bacon is a masterclass in comfort food, offering a warm and savory flavor profile that is both elegant and completely crave-worthy.
Boosting the flavor
You can easily boost the flavor of this incredible gratin with a few simple tweaks. Try swapping the Gruyère for an extra-sharp white cheddar to add a more pronounced tang, or stir a tablespoon of whole grain mustard into the cream sauce for a subtle, aromatic kick. For a delightful textural contrast, sprinkle buttery panko breadcrumbs mixed with Parmesan over the top before baking for an even crisper, more golden finish. A drizzle of high-quality truffle oil right before serving introduces an elegant, earthy depth that complements the root vegetables beautifully. If you love experimenting with herbs, consider our guide to creating your own custom DIY spice blends to find a perfect match. Finally, serve each portion with a simple side salad to cut through the richness; our favorite easy lemon vinaigrette provides a bright, acidic counterpoint that makes every cheesy bite taste even better.
Tips for Success
Best practices for results
For the best consistency and even cooking, always slice your vegetables to a uniform thickness, because this ensures they all become tender at the same time. Use a mandoline slicer for the most precise results, although a sharp knife and a steady hand will also work perfectly. Generously grease your baking dish with butter before assembling, so your Cheesy Root Vegetable Gratin | Spoon Fork Bacon releases easily and develops a beautifully golden, crisp crust on the bottom and sides. Finally, allow the gratin to rest for about 10 minutes after baking, as this helps the creamy sauce set for cleaner slices.
Mistakes to avoid
A common error is using cheese that is too oily or does not melt well, which can cause your sauce to break and become greasy instead of luxuriously creamy. To prevent this, stick with the recommended cheeses that melt smoothly, such as Gruyère or a sharp white cheddar. Another frequent mistake is not seasoning the vegetable layers adequately as you build the gratin, even though the sauce is flavorful, because this can lead to bland bites. For a foolproof guide on building flavor in every layer, review our essential guide to how to make a perfect gratin. Furthermore, do not rush the baking time by increasing the oven temperature, as the vegetables need a longer, gentler cook to become perfectly tender without burning the top; if your top is browning too quickly, tent it with foil.
