Essential Ingredients for Cheesy Root Vegetable Gratin
Root Vegetables (Potatoes, Carrots, Parsnips): These form the heart of your Cheesy Root Vegetable Gratin, providing texture and subtle sweetness. I like using a mix for variety—potatoes for creaminess, carrots for color, and parsnips for a nutty depth. Slice them thinly to ensure even cooking, and don’t worry if they’re not perfect; the cheese sauce ties it all together beautifully.
Cheddar and Parmesan Cheese: Sharp cheddar melts into a luxurious sauce, while parmesan adds a salty crunch on top. In this gratin, they create that irresistible pull-apart quality we all love. I’ve found grating your own cheese makes a world of difference for smoothness.
Cream and Milk for the Sauce: This duo builds a velvety béchamel base that’s essential for the Cheesy Root Vegetable Gratin’s creaminess. Use full-fat for richness, but whole milk works if you’re lightening it up. Stir in garlic and thyme for extra aroma that infuses every bite.
How to Make Cheesy Root Vegetable Gratin
Prep the Vegetables
Start by washing and peeling your root vegetables, then slice them thinly—about 1/8-inch thick—using a mandoline if you have one for even layers in your Cheesy Root Vegetable Gratin. Toss the slices with a bit of salt and olive oil to enhance their flavors as they bake. In my experience, this step takes about 15 minutes but sets up the dish for success; you’ll notice how the thin slices prevent sogginess. Arrange a layer in your buttered baking dish, and you’re off to a great start.
Make the Cheesy Sauce
While the veggies rest, melt butter in a saucepan over medium heat, whisk in flour to form a roux, then slowly add milk and cream until it thickens into a smooth sauce. Stir in shredded cheddar until it melts into gooey perfection, seasoning with nutmeg, salt, and pepper for that classic gratin taste. The aroma here is heavenly—creamy and inviting, with bubbles forming gently. This should take around 10 minutes, and it’s worth the arm workout for the Cheesy Root Vegetable Gratin payoff.
Layer and Bake
Pour a third of the sauce over the first layer of veggies, then repeat with more slices and sauce until your dish is full, topping with parmesan for a crispy crown. Bake at 375°F for 60-70 minutes until the top is golden and bubbly, and a knife slides easily through the tender roots. I’ve learned to tent with foil halfway if it browns too fast, ensuring even cooking in this Cheesy Root Vegetable Gratin. Let it rest 10 minutes post-oven to set, and dig in to that comforting warmth.

How to Store Cheesy Root Vegetable Gratin

Customizing Your Cheesy Root Vegetable Gratin
Swap in sweet potatoes for extra sweetness or add turnips for earthiness in your Cheesy Root Vegetable Gratin—experiment freely.

Recipe Details
Ingredients
- 01 1 tablespoon unsalted butter (softened)
- 02 1-2 long sweet potatoes (about 2 inches thick, peeled)
- 03 3-4 large parsnips (ends trimmed and peeled)
- 04 3-5 small beets (peeled)
- 05 14 tablespoons heavy cream (divided (whole milk is fine, but mixture won't thicken as much or be as creamy))
- 06 4 ounces grated Parmesan (divided)
- 07 1 tablespoon fresh minced thyme (divided (plus more for garnish))
- 08 1 garlic clove (minced)
- 09 1 ounce shredded gruyere
- 10 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.

Frequently Asked Questions About Cheesy Root Vegetable Gratin
Can I make Cheesy Root Vegetable Gratin ahead of time?
Yes, assemble it up to 24 hours in advance, cover, and refrigerate; bake when ready, adding 10 extra minutes. This is great for holidays. Just don’t bake and reheat multiple times to keep it fresh.
How long does Cheesy Root Vegetable Gratin last in the fridge?
It stays good for 3-4 days when stored properly in the fridge. Beyond that, freeze it. Always reheat to 165°F for safety.
Is Cheesy Root Vegetable Gratin gluten-free?
The base isn’t, due to the flour roux, but substitute with cornstarch for a gluten-free version. It works just as well. Check labels on cheeses too.
What if I don’t have parsnips for the recipe?
No problem—use more carrots or add rutabaga to your Cheesy Root Vegetable Gratin; it maintains the balance. I often improvise with what’s in season. The flavors adapt nicely.
Can I use pre-shredded cheese?
It’s okay in a pinch, but fresh-grated melts better without anti-caking agents. For the best Cheesy Root Vegetable Gratin, grate your own. The difference in texture is noticeable.

Replace dairy with coconut milk and vegan cheese shreds in this Cheesy Root Vegetable Gratin; it bakes up creamy. Add nutritional yeast for cheesiness. It’s a crowd-pleaser for plant-based eaters.
Why is my gratin watery?
Thicker slices or excess moisture from veggies cause that—pat them dry and slice thin. Next time, it should be perfect. Patience in baking helps too.

Absolutely, it’s mild and cheesy, like mac and cheese with veggies. Hide the roots if picky! It’s a sneaky way to add nutrition.
