How to Make Cheesy Root Veggie Gratin Recipe

Step 1: Preheat Your Oven

Start by setting your oven to 375°F (190°C). This temperature lets the vegetables cook evenly while allowing the cheese to melt into a gorgeous golden topping without burning.

Step 2: Prepare the Baking Dish

Grease a large baking dish with butter to prevent sticking. This little step ensures your gratin slides out beautifully and the edges get that lovely buttery crisp.

Step 3: Make the Cream Sauce

In a medium saucepan, gently warm the heavy cream, milk, minced garlic, and fresh thyme. Season with salt and pepper, and keep the mixture just warm—avoid boiling to maintain a silky texture and prevent the cream from curdling.

Step 4: Layer the Root Vegetables

Place half of your sliced potatoes, carrots, and parsnips evenly in the baking dish. These vibrant layers provide a wonderful textural contrast that makes every bite interesting and satisfying.

Step 5: Add Cream Mixture and Cheese

Pour half of the warm cream sauce over the veggies, ensuring each slice feels coated in that rich bath of flavor. Then sprinkle half of the cheddar cheese evenly on top, letting it melt into the roots for that irresistible gooeyness.

Step 6: Repeat the Layers

Layer your remaining potatoes, carrots, and parsnips, followed by the rest of the cream mixture and cheddar cheese. This layering technique is key to building deep, luscious flavor and getting perfectly cooked vegetables throughout.

Step 7: Top with Parmesan and Bake

Sprinkle the Parmesan cheese over the top, then cover the dish with foil. Bake for 30 minutes to let the veggies soften and meld with the creamy sauce.

Step 8: Finish Baking Uncovered

Remove the foil and bake for another 25-30 minutes. This last step lets the top become golden brown and satisfyingly crispy, making that gorgeous crust that sets a gratin apart.

Step 9: Rest and Garnish

Let your gratin rest for about 10 minutes after taking it out of the oven. This pause helps everything set nicely so it slices cleanly. Sprinkle fresh parsley on top for that bright, fresh pop that balances the richness.

How to Serve Cheesy Root Veggie Gratin Recipe

Garnishes

A sprinkle of fresh parsley is a simple but effective garnish that adds color and a touch of freshness to the rich, cheesy gratin. You can also try finely chopped chives or a little cracked black pepper for an extra layer of aroma and visual appeal.

Side Dishes

This gratin pairs beautifully with crisp green salads or lightly steamed greens like broccoli or green beans to balance its richness. For a heartier meal, roasted meats or grilled chicken complement the creamy cheesy veggies perfectly.

Creative Ways to Present

For a charming presentation, serve the gratin in individual ramekins—perfect for dinner parties or cozy nights in. You can also prepare it in a cast iron skillet for rustic appeal and a crispier edge that everyone will love.

Make Ahead and Storage

Storing Leftovers

Wrap any leftover gratin tightly and refrigerate. It will keep well for up to 3 days, making for delicious next-day comfort food that’s easy to reheat in the oven or microwave.

Freezing

This Cheesy Root Veggie Gratin Recipe freezes surprisingly well. Just transfer portions into freezer-safe containers or wrap the whole dish tightly. It can be frozen for up to 2 months, though the texture might soften slightly upon thawing.

Reheating

The best way to reheat your gratin is in the oven at 350°F (175°C) until warmed through and the top crisps up again. This keeps the creamy texture intact without turning soggy, bringing back that fresh-from-the-oven magic.

FAQs

Can I use other root vegetables in this gratin?

Absolutely! While potatoes, carrots, and parsnips are classic here, you can also add sweet potatoes, turnips, or even rutabaga for a twist. Just make sure to slice them thin for even cooking.

How do I make the dish less rich?

Use half-and-half instead of heavy cream, or reduce the cheese slightly. Adding a bit more milk can also lighten the sauce while keeping the gratin delicious.

Yes! Assemble the gratin, cover it, and keep it in the fridge for up to a day before baking. This makes it a great option for meal planning or entertaining without stress.

What’s the best cheese to use for a perfect gratin?
