Ingredients You’ll Need

The magic of this gratin lies in its simplicity—each ingredient is carefully chosen to contribute to the layers of flavor, texture, and color that make this dish truly unique. Don’t be daunted by the list; these familiar ingredients come together in such an effortless way, promising a stunning outcome.

• 1 tablespoon unsalted butter: Perfect for greasing the dish and adding richness without overpowering.
• 1-2 long sweet potatoes (about 2 inches thick), peeled: Their natural sweetness balances the savory cheese beautifully.
• 3-4 large parsnips, ends trimmed and peeled: Adds a subtle earthiness and a creamy texture when baked.
• 3-5 small beets, peeled: Brings vibrant color and an earthy depth with a touch of sweetness.
• 14 tablespoons heavy cream, divided: The key to the gratin’s luscious creaminess and perfectly tender vegetables.
• 4 ounces grated Parmesan, divided: Adds a salty, nutty flavor that enhances every layer.
• 1 tablespoon fresh minced thyme, divided, plus more for garnish: Thyme’s herbaceous aroma complements the root vegetables superbly.
• 1 garlic clove, minced: Offers a subtle pungency that rounds out the flavors.
• 1 ounce shredded Gruyere: Melts beautifully to create a bubbly, golden crust.
• Salt and pepper to taste: Essential for seasoning and bringing out the natural flavors.

How to Make Irresistible Cheesy Root Vegetable Gratin with 3 Layers

Step 1: Prepare and Preheat

Start by preheating your oven to 400˚F and greasing a 3-quart baking dish with the softened butter. This simple step ensures your gratin won’t stick and sets the stage for beautifully cooked layers.

Step 2: Slice the Vegetables

Next, slice the sweet potatoes, parsnips, and beets into very thin rounds. Keeping them thin helps the vegetables cook evenly and allows for that tender, melt-in-your-mouth texture that defines a great gratin. To keep flavors distinct and vibrant, transfer each vegetable to its own bowl.

Step 3: Toss Vegetables with Cream, Cheese, and Herbs

Divide the cream between the vegetables—4 tablespoons over sweet potatoes and parsnips, and 2 tablespoons over beets. Then sprinkle each bowl with Parmesan and thyme, season generously with salt and pepper, and gently toss to coat every slice. This step infuses each vegetable layer with flavor while ensuring they’re luxuriously creamy.

Step 4: Prepare the Baking Dish

Pour the remaining 1/4 cup of cream into the bottom of the greased baking dish. Sprinkle with half an ounce of Parmesan and the minced garlic, which will create a fragrant, flavorful foundation for the gratin’s layers.

Step 5: Assemble the 3 Layers

Here’s where your gratin starts to come alive. Arrange the vegetables standing on a bias: begin with a stack of sweet potatoes at the top of the dish, followed by a row of parsnips, then a row of beets. Repeat this sequence to create six rows of these beautiful root vegetables. This stacking method not only looks impressive but also ensures you get a bit of each veggie in every bite.

Step 6: Season and Cover

Once assembled, season the top layer with salt, pepper, and the remaining Parmesan. Cover the dish tightly with foil and bake for 30 minutes, allowing the vegetables to soften and the flavors to meld perfectly under gentle heat.

Step 7: Add the Gruyere and Finish Baking

Remove the foil and sprinkle shredded Gruyere over the top. Bake uncovered for an additional 18-20 minutes until the vegetables are fork-tender, the cheese fully melted, and the top boasts a gorgeous golden-brown crust that’s just irresistible.

Step 8: Garnish and Serve

Finish with a sprinkle of fresh thyme leaves for an herby burst of color and aroma. This final touch elevates your Irresistible Cheesy Root Vegetable Gratin with 3 Layers from delicious to simply unforgettable.

How to Serve Irresistible Cheesy Root Vegetable Gratin with 3 Layers

Garnishes

A handful of fresh thyme leaves scattered over the top adds a lovely bright note, but you can also try a light drizzle of good-quality olive oil or a sprinkle of crushed toasted walnuts for a crunchy contrast that pairs beautifully with the creamy layers.

Side Dishes

This gratin is hearty enough to shine on its own, but if you want to create a well-rounded meal, consider serving it alongside a crisp green salad or roasted protein like herb-roasted chicken or grilled salmon. The fresh or smoky elements will balance the dish’s richness wonderfully.

Creative Ways to Present

If you’re aiming to impress guests, try serving this gratin in individual mini baking dishes or ramekins. Layer the vegetables in the same order to showcase those stunning colors, and you’ll have a captivating presentation that feels extra special and personalized.

Make Ahead and Storage

Storing Leftovers

After enjoying your Irresistible Cheesy Root Vegetable Gratin with 3 Layers, store any leftovers in an airtight container in the refrigerator. It will keep beautifully for up to 3 days while maintaining its flavor and texture.

Freezing

You can also freeze this gratin for future enjoyment. Wrap it tightly in foil or use a freezer-safe container and freeze for up to 2 months. Thaw in the refrigerator overnight before reheating to preserve its delicious layers.

Reheating

To reheat, place the gratin in a preheated oven at 350˚F for about 20-25 minutes until warmed through and the cheese on top bubbles once again. Avoid the microwave if possible, to keep that delicate texture and melt-in-your-mouth experience intact.

FAQs

Can I substitute other cheeses for Gruyere?

Absolutely! While Gruyere offers a lovely nutty melt, you can also use Fontina, Mozzarella, or even a sharp Cheddar depending on your taste preferences and what you have on hand.

Do I need to peel the root vegetables?

Peeling is recommended for this recipe to ensure even cooking and a smoother texture, especially for beets. However, if you prefer a more rustic gratin, you can leave the skins on after thoroughly washing and scrubbing the vegetables.

Can I prepare the gratin completely in advance?

You can assemble the layers a few hours before baking and keep the dish covered in the fridge. Just bake it fresh when ready, which helps preserve all the flavors and textures at their best.

What if I don’t have fresh thyme?

Dried thyme can be used in a pinch; just use a bit less since dried herbs are more concentrated. Alternatively, fresh rosemary or sage would also complement the root vegetables nicely.

Is there an alternative to heavy cream?

For a lighter option, you might try half-and-half or whole milk, but keep in mind the gratin’s signature richness and creaminess come from the heavy cream, so substitutes may slightly alter the texture and flavor.
