Description
Crispy Parmesan and Gruyere Potato Gratin is a rich, golden-baked side dish layered with tender Yukon Gold potatoes, infused garlic cream, nutty Gruyere, and sharp Parmesan. Perfect for holidays or a cozy dinner, this gratin is both indulgent and irresistibly crispy.
Ingredients
2 ½ pounds Yukon Gold potatoes, thinly sliced
2 cups heavy cream
1 ½ cups shredded Gruyere cheese
1 cup freshly grated Parmesan cheese
2 cloves garlic, minced (plus 1 clove for rubbing the dish)
4 sprigs fresh thyme (plus more for garnish)
1 teaspoon salt
½ teaspoon freshly ground black pepper
2 tablespoons unsalted butter, cubed
Instructions
1. Preheat oven to 375°F (190°C). Rub a baking dish or cast iron skillet with a cut clove of garlic or brush with melted butter.
2. Peel the Yukon Gold potatoes and slice them into very thin rounds (about 1/8-inch thick) using a mandoline slicer for uniformity.
3. In a saucepan, combine heavy cream, minced garlic, thyme sprigs, salt, and pepper. Simmer over medium heat until warmed and fragrant. Remove from heat and discard thyme sprigs.
4. Begin layering the potatoes in the prepared dish, overlapping slices. After each layer, pour a bit of the cream mixture and sprinkle with Gruyere and Parmesan. Repeat until all ingredients are used, finishing with a layer of Parmesan on top.
5. Dot the surface with cubed butter.
6. Bake uncovered for 50–60 minutes or until the top is bubbly and deeply golden, and potatoes are tender when pierced.
7. Let it rest for 10–15 minutes before serving. Garnish with extra thyme if desired.
Notes
For best slicing results, use a mandoline to ensure uniform potato thickness which promotes even cooking.
Let the gratin rest before slicing to help the layers set and hold together.
Reheat leftovers in the oven uncovered to restore the crisp cheese top.
