Everyone loves a cheesy, creamy potato side dish. This is my take on the traditional potatoes au gratin, but with an Italian twist. These cacio e pepe potatoes are so good, you won’t miss the pasta at all!

8 large russet potatoes

1 stick salted butter, melted, plus 1 stick salted butter, plus more for the baking dish

2 cups sour cream

2 cups half-and-half

1 cup grated Pecorino-Romano, plus more for serving

1 white onion, sliced

Kosher salt and freshly ground black pepper

1 cup dried potato flakes

Directions

Special equipment:

a Japanese mandoline

Preheat the oven to 400 degrees F.
Scrub the potatoes, then thinly slice on a Japanese mandoline (about 1/8-inch thick). Place in a bowl of water, then rinse and drain.
To a large bowl, add the melted butter, sour cream, half-and-half, pecorino, onion, salt and 2 tablespoons pepper and mix with the potatoes. Butter a 9-by-13-inch baking dish, then place the potato mixture into the dish. Bake until the potatoes are tender and the cream mixture is bubbly, 45 minutes to 1 hour.
Meanwhile, in a saute pan over medium-low heat, melt the remaining stick of butter. Let the butter start to foam, then add the potato flakes. Season with salt and lots of black pepper. Gently cook until golden brown.
Remove the baked potatoes from the oven and top with the crunchy potato mixture. Finish with more pecorino over the top.
