Cheesy Root Vegetable Gratin

I’ve always seen my kitchen as my favorite playground. Growing up, I learned that cooking was more than a task—it was a way to gather, celebrate, and create memories. Now, with my two energetic kids, I love turning simple, fresh ingredients into meals that spark their imagination. Family dinners are never just about food—they’re full of laughter, playful taste tests, and endless questions about flavors and origins.

One of our favorites is my Cheesy Root Vegetable Gratin. Sweet potatoes, parsnips, and beets layered with creamy cheese create a bubbling, golden dish that warms the soul. Seeing Lily and Jasper’s eyes light up every time I serve it reminds me why I love experimenting in the kitchen.

This dish is both indulgent and wholesome, highlighting the beauty of seasonal root vegetables while keeping everyone happy at the table. It’s a recipe that turns simple ingredients into a family favorite.

How to Make Cheesy Root Vegetable Gratin

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

Directions

  1. Preheat your oven to 400°F (200°C). Grease a 3-quart baking dish with softened butter.
  2. Slice the sweet potatoes, parsnips, and beets into very thin rounds. A mandoline is the best tool for this, providing even slices that cook uniformly.
  3. Place each vegetable into its own bowl. Pour 4 tablespoons of cream over the sweet potatoes and parsnips, and 2 tablespoons over the beets.
  4. Top each bowl of sliced vegetables with ½ ounce of grated Parmesan and 1 teaspoon of minced thyme. Don’t forget to season each bowl generously with salt and pepper. Toss everything together until all slices are well coated.
  5. Pour the remaining ¼ cup cream into the bottom of the baking dish. Sprinkle with ½ ounce of Parmesan and the minced garlic.
  6. Stand the slices of sweet potatoes on a bias, forming the first row. Follow with parsnips and then beets. Continue layering until all veggies are used, creating six rows of colorful root vegetables.
  7. Season the top of the gratin with salt, pepper, and the remaining Parmesan.
  8. Cover the dish with foil and bake for 30 minutes or until the vegetables are tender.
  9. Uncover the dish and sprinkle with shredded gruyere. Return to the oven uncovered, and bake for an additional 18 to 20 minutes or until fork-tender, the cheese is melted, and the top is lightly browned.
  10. Finish with a sprinkle of fresh thyme leaves before serving.

How to Serve Cheesy Root Vegetable Gratin

This Cheesy Root Vegetable Gratin stands beautifully on its own as a comforting centerpiece for your meal. If you want, serve it with a simple side salad for a pop of freshness. Amelia often pairs it with roasted chicken or grilled fish for a balanced meal.

As the gratin cools slightly from the oven’s heat, slice portions straight from the dish. The layers of colorful vegetables peek through, inviting everyone to dive in! Amelia’s children especially love scooping their servings, creating little “mountains” of gratin on their plates, and mixing it with other foods, making each bite a new adventure in flavors and textures.

How to Store Cheesy Root Vegetable Gratin

Leftovers are a wonderful aspect of Cheesy Root Vegetable Gratin! If you happen to have any left (which is rare in Amelia’s home), let it cool completely before storing it.

  • Place the leftover gratin in an airtight container and refrigerate for up to three days.
  • To reheat, cover it with foil and pop it back in a 350°F (175°C) oven until warmed through, about 20-25 minutes.

The flavors meld even more overnight, making for a delightful next-day treat!

Tips to Make Cheesy Root Vegetable Gratin

  • Choose Your Vegetables: Feel free to mix in other root vegetables like carrots or turnips for variety.
  • Don’t Rush the Slicing: Taking your time will yield even slices, ensuring that everything cooks uniformly. If your kids are helping, they can use kid-safe knives for additional fun!
  • Customize the Cheese: While gruyere adds a lovely nuttiness, mixing in a bit of cheddar or gouda can also introduce new flavors.
  • Add a Crunch: For added texture, consider sprinkling some breadcrumbs mixed with Parmesan on top before the final bake for a crispy topping.

Variation

While Cheesy Root Vegetable Gratin is perfect as is, you can also add a hint of warmth by including spices like nutmeg or a dash of cayenne pepper. This playful twist can make the gratin feel global, showcasing how traditions can blend seamlessly in the kitchen.
