Description
This Crispy Parmesan and Gruyere Potato Gratin is a golden, cheesy side dish that layers thinly sliced Yukon Gold potatoes with a rich cream mixture, garlic, thyme, and a blend of nutty Gruyere and sharp Parmesan cheeses. It’s elegant enough for holidays and comforting enough for weeknight dinners. Baked until bubbly and golden, every bite is creamy and packed with flavor.
Ingredients
2 pounds Yukon Gold potatoes
1 1/2 cups heavy cream
1 cup shredded Gruyere cheese
1/2 cup freshly grated Parmesan cheese
1 clove garlic, minced
1 teaspoon fresh thyme leaves
1 teaspoon salt
1/2 teaspoon black pepper
2 tablespoons unsalted butter, cut into small pats
Instructions
1. Preheat oven to 375°F (190°C). Rub the inside of a baking dish with the cut side of a garlic clove and lightly butter it.
2. Slice the Yukon Gold potatoes into 1/8-inch thick rounds using a mandoline or sharp knife.
3. Layer half the sliced potatoes in the baking dish, slightly overlapping. Season with half the salt, pepper, thyme, and garlic.
4. Sprinkle half of the Gruyere and Parmesan over the potatoes.
5. Repeat the layering with remaining potatoes, seasonings, and cheeses.
6. Pour the heavy cream evenly over the layers.
7. Dot the top with pats of butter and sprinkle extra Parmesan for crispiness.
8. Cover with foil and bake for 30 minutes.
9. Remove foil and continue baking for 20–25 more minutes until golden and bubbly.
10. Let rest 10–15 minutes before serving to allow the layers to set.
Notes
For best texture, slice potatoes evenly and thin—aim for 1/8-inch slices.
Let the gratin rest before serving so the creamy layers hold together.
Use high-quality cheese for maximum flavor and melt—aged Gruyere and real Parmesan make a difference.
