Ingredients
For the Gratin
- 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
How to Make Cheesy Root Vegetable Gratin
Step 1: Preheat the Oven
Preheat your oven to 400˚F. Grease your 3-quart baking dish with softened butter to prevent sticking.
Step 2: Prepare the Vegetables
Slice the sweet potatoes, parsnips, and beets into very thin rounds. A mandoline slicer makes this step easier. Place each type of vegetable into its own bowl.
Step 3: Coat the Vegetables
Pour 4 tablespoons of cream over each bowl of sweet potatoes and parsnips. Add 2 tablespoons of cream over the beets. Top each bowl with ½ ounce of grated Parmesan and 1 teaspoon of minced thyme. Season generously with salt and pepper. Toss until all slices are well coated.
Step 4: Assemble in Baking Dish
Pour the remaining ¼ cup cream into the bottom of your greased baking dish. Sprinkle with ½ ounce of Parmesan and add minced garlic.
Step 5: Layer the Vegetables
Take a stack of sweet potato slices and line them standing up on a bias at one end of the baking dish. Follow with a row of parsnips, then a row of beets. Repeat until you’ve created six rows using all vegetables.
Step 6: Season and Bake
Season the top layer with salt, pepper, and sprinkle with remaining Parmesan. Cover with foil and bake for about 30 minutes or until vegetables are soft.
Step 7: Add Gruyere Cheese
After baking covered, uncover your gratin and top it with shredded gruyere cheese.
Step 8: Final Bake
Return the gratin to the oven uncovered. Continue to bake for an additional 18 to 20 minutes or until vegetables are fork-tender, cheese has melted beautifully, and the top is lightly browned.
Step 9: Garnish and Serve
Finish off by sprinkling fresh thyme leaves over your delicious Cheesy Root Vegetable Gratin before serving warm. Enjoy!

How to Perfect Cheesy Root Vegetable Gratin
To ensure your Cheesy Root Vegetable Gratin turns out perfectly every time, consider these helpful tips.
- Use a Mandoline: Slicing your vegetables evenly ensures they cook uniformly, resulting in a consistent texture throughout the dish.
- Layer Thoughtfully: Alternate layers of sweet potatoes, parsnips, and beets to create visual appeal and balanced flavors in each bite.
- Don’t Skip the Seasoning: Generously season each layer with salt and pepper to enhance the natural flavors of the vegetables.
- Cover During Initial Baking: Covering the gratin initially helps steam the vegetables, ensuring they become tender before browning.
- Watch for Browning: Keep an eye on the gratin during the final baking stage to prevent over-browning; you want a golden top, not burnt edges.
- Let it Rest: Allowing the gratin to rest for about 10 minutes after baking will help it set up better for easier serving.

Common Mistakes to Avoid
Avoiding common mistakes will help ensure your Cheesy Root Vegetable Gratin turns out perfectly.
- Boldly slice vegetables too thick: Thick slices will result in uneven cooking. Use a mandoline or sharp knife to create thin, even rounds for consistent texture.
- Not seasoning adequately: Under-seasoned vegetables can lead to bland flavors. Be generous with salt and pepper during preparation to enhance the dish’s overall taste.
- Ignoring the baking time: Overbaking can dry out the gratin while underbaking can leave vegetables hard. Check for doneness periodically to achieve the ideal tender texture.
- Neglecting to layer properly: Random layering may cause uneven cooking. Follow a structured layering method for better heat distribution and presentation.
- Forgetting about fresh herbs: Fresh herbs add a burst of flavor at the end. Don’t skip this step; they elevate the dish’s taste and look.
