Step-by-step preparation of Sheet-Pan Root Vegetable Gratin
Making a delicious sheet-pan root vegetable gratin is simpler than you might think. Follow these steps, and in no time, you'll have a stunning dish that’s both comforting and nutritious!
Preheat and prepare the baking sheet
Start by adjusting your oven rack to the middle position and preheating your oven to 450°F (230°C). While it's heating up, grab a 17 ½-by-12 ½-inch rimmed baking sheet. Coat the bottom and sides with 1 tablespoon of softened unsalted butter, ensuring a nice non-stick surface for the gratin.
Sauté the aromatics
In a large skillet, melt the remaining 2 tablespoons of butter over medium heat. Add the thinly sliced yellow onion and ½ teaspoon of kosher salt. Sauté for about 10 minutes, stirring occasionally, until the onion is softened and starts to turn golden brown. Add in 4 large cloves of minced garlic and stir for about a minute until fragrant. Then, deglaze the skillet with ¼ cup of dry sherry (feel free to substitute with vegetable broth if you prefer!), cooking until evaporated, around 1 minute. Reduce the heat to low and add 2 cups of heavy cream, along with thyme, sage, pepper, nutmeg, and the remaining salt. Bring this mixture to a simmer and promptly remove it from the heat.
Prepare the cream mixture
The cream mixture is a key component of your sheet-pan root vegetable gratin, as it brings all the flavors together beautifully. Let it sit while you proceed with the next steps.
Slice the root vegetables
Now, it's time to get your hands on those root vegetables! Use a mandoline or a sharp knife to thinly slice 3 medium parsnips, 2 large sweet potatoes, and 2 large golden beets into ⅛-inch-thick rounds. Precision is key here, so take your time to ensure even slices for consistent cooking.
Assemble the gratin
It’s assembly time! Layer half of the vegetable slices on the prepared baking sheet, shingling them tightly to avoid any gaps. Sprinkle with 1 teaspoon of kosher salt and ⅔ cup of grated Parmigiano-Reggiano. Top this with the remaining vegetable slices and another 1 teaspoon of salt. Finally, grab that luscious cream mixture and pour it evenly over the entire arrangement.
Bake covered
Cover the baking sheet tightly with aluminum foil and bake in your preheated oven. This will help steam the vegetables, allowing them to cook evenly. Bake for 20 to 30 minutes, until the slices are tender when pierced with a fork.
Add the cheese and bake uncovered
Once your vegetables are soft, carefully remove the foil. Now is the time to sprinkle the top with 6 ounces of shredded Gruyère cheese and the remaining Parmesan. This combination will create an irresistibly cheesy crust. Return the uncovered baking sheet to the oven for another 20 minutes, rotating it halfway through for even browning.
Let it cool and garnish
Once golden brown and bubbly, remove the gratin from the oven and let it sit for 5 minutes. This cooling time is crucial as it allows the flavors to meld beautifully. Just before serving, sprinkle it with fresh thyme leaves, sage leaves, and a dash of black pepper for an extra flavor boost.
And there you have it! This sheet-pan root vegetable gratin is not only delicious but also a stunning addition to any meal. Enjoy it as a side dish or a hearty main course—your taste buds will thank you!
