What you’ll need

- 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
Ingredient notes & swaps
- Sweet potatoes: Can substitute with regular potatoes for a different flavor.
- Cream: Whole milk works if you’re in a pinch, though it won’t be as rich.
- Thyme: Fresh herbs like rosemary or sage can be used for an aromatic twist.
- Gruyere: Substitute with a different cheese, like sharp cheddar, for a unique flavor.
How to make it
This cheesy root vegetable gratin is simple to assemble and results in a delightful dish that is perfect for any occasion. Follow these steps for a delicious final product:
- Preheat your oven to 400°F. Grease a 3-quart baking dish with softened butter.
- Slice the sweet potatoes, parsnips, and beets into very thin rounds; a mandoline works best! Transfer each vegetable into its own bowl.
- In each bowl, pour 4 tablespoons of cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets. Top each with ½ ounce of grated Parmesan and 1 teaspoon of minced thyme. Generously season with salt and pepper, then toss until everything is well coated.
- Pour the remaining ¼ cup of cream into the bottom of the greased baking dish. Sprinkle with ½ ounce of Parmesan and the minced garlic.
- Create a stack of the sweet potatoes and line them up standing on a bias at the top of the baking dish. Follow with a row of parsnips, then beets. Repeat with the remaining vegetables, creating a total of 6 rows.
- Once layered, season the top with additional salt, pepper, and sprinkle the remaining Parmesan over the top.
- Cover the dish with foil and bake for 30 minutes or until the vegetables are tender.
- Uncover and top the gratin with shredded gruyere cheese. Place it back in the oven, uncovered, for an additional 18 to 20 minutes, or until the vegetables are fork-tender, cheese is melted, and the top is lightly browned.
- Finish with a sprinkle of fresh thyme leaves and serve warm.
Pro Tip: For a creamier texture, let the gratin sit for a few minutes after baking. This allows the flavors to meld beautifully.
You’ll know the dish is ready when you see the cheese melted and golden brown, the vegetables soft to the touch, and that heavenly aroma filling your kitchen.
Helpful cooking tips
- Use a mandoline for uniform slicing; it not only looks better but ensures even cooking.
- If you prefer a crispier top, broil the gratin in the last few minutes of cooking.
- You can add layers of sautéed onions or mushrooms for additional flavor.
Best ways to enjoy it
Cheesy root vegetable gratin is perfect for pairing with a crisp salad or some hearty roasted meats. It’s a lavish side dish that can elevate any meal. For a vegetarian option, serve with a side of sautéed greens or a light vinaigrette salad.
How to store & freeze
To store leftovers, allow the gratin to cool completely, then cover tightly with plastic wrap or aluminum foil. Refrigerate for up to three days. If you want to freeze it, portion it into airtight containers and freeze for up to 2 months. To reheat, bake in a preheated oven until bubbling hot.
How to fix common issues
If your gratin turns out too watery, consider the following tips:
- Use less cream in the layering process.
- Allow the gratin to sit uncovered for a bit longer to let excess liquid evaporate.
- If it’s overcooked, the vegetables can become mushy; keep an eye on them during the baking process.

Your questions answered
Can I make cheesy root vegetable gratin in advance?
Yes, you can prep the gratin a day ahead and refrigerate it unbaked. Just cover it with plastic wrap, and when you’re ready, bake it as directed, adding a few extra minutes to ensure it heats through.
What’s the best way to cut the vegetables?
A mandoline is ideal for slicing root vegetables into uniform thin rounds, which helps them cook evenly. If you don’t have one, a sharp knife can work too; just try to keep the slices as even as possible.
Can I use different cheeses besides parmesan and gruyere?
Absolutely! Feel free to experiment with whatever cheese you have on hand. Cheddar, gouda, or even a creamy blue cheese can add a delightful twist to the dish.
Is there a lower-calorie version of this recipe?
To lighten it up, you can substitute half of the cream with vegetable broth or milk, and use less cheese. The flavor will still be rich but with fewer calories.
How can I add more flavor to the dish?
Incorporate herbs and spices like rosemary, sage, or paprika to enhance the flavor profile. You can also add a splash of white wine to the cream for extra depth.
