Scalloped Potato Gratin

Updated: Nov 10, 2020

Since days of the week are kind of a moot point at the moment, I was actually grateful that this spectacular Scalloped Potato Gratin gave me real Sunday feels. The good kind, not the scary kind! The kind where everyone gathers around the table for a leisurely and delicious lunch and lingers afterwards. Even if it is “only” us, not that that doesn’t feel like quite a handful sometimes. 😆 So thank you Melissa Clark and NYT Cooking for saving our Sunday! This gratin was such a showstoppping centerpiece that it didn’t need much on the side, so we simply served it with crispy grilled sausages and wilted garlic-y spinach.

There were a few things I changed with this recipe. It called for 5 eggs, but that felt very indulgent, know what I mean? Right now, that last grocery haul has to last us a while, so three eggs was quite sufficient. Same with the three cups of cream, substituted two cups of cream and one of milk. I also mixed Gruyère and cheddar in equal parts instead of only Gruyère and subbed fresh rosemary for the sage because it was what I had on hand.

Changes notwithstanding, this is an amazing dish that you should definitely try! xoxo Donata


¼ cup unsalted butter (1/2 stick, 55 g), plus more for greasing the aluminum foil, at room temperature

3 cups (720 ml) heavy cream (alternative: 2 cups (480 ml) cream, 1 cup (240 ml) milk)

¼ cup (5 g) chopped fresh sage leaves (alternative: 1 sprig rosemary)

4 fat garlic cloves, finely grated or minced

¼ teaspoon freshly grated nutmeg

1 ½ teaspoons fine sea salt, plus more as needed

5 large eggs (I used 3 eggs and it turned out great!)

4 pounds (2 kilos) russet potatoes (about 6 large or 8 medium)

Freshly ground black pepper

2 ¼ cups (8 1/2 ounces, 280 g) grated Gruyère (I used a 50/50 mix of Gruyère and cheddar)


  1. Heat oven to 350 degrees F (180 C), and brush 1/4 cup butter on a rimmed 17-by-13-inch baking sheet. Brush one or two pieces of foil (enough to cover the top of the pan) with more butter. Set the foil aside.

  2. In a medium pot, bring the cream, sage, garlic, nutmeg, and a pinch of salt to a simmer. Simmer until reduced by a quarter, about 15 minutes.

  3. In a large heatproof bowl, lightly beat the eggs. Beating constantly, gradually add a little of the hot cream to the eggs, then slowly pour in the rest of the hot cream, whisking to prevent the eggs from curdling. Set aside.

  4. Using a mandoline or a sharp knife, slice the potatoes into 1/8-inch-thick rounds.

  5. Arrange one layer of potatoes on the buttered baking sheet, slightly overlapping the slices. Sprinkle with 3/4 teaspoon of the salt, add pepper to taste, then pour half the egg mixture over the potatoes. Top with 1/2 cup cheese. Repeat the layers of potato, seasoning and egg mixture. Top with the remaining 1 3/4 cups cheese. Cover the baking sheet with the foil (buttered-side down) and bake for 20 minutes. Remove the foil and bake until the potatoes and cheese are browned and bubbling, 25 to 30 minutes. Let cool slightly, then serve.
