Step 1

In a large saucepan over medium heat, bring the potatoes and milk to a gentle simmer. Continue simmering the potatoes for 15 minutes, until they just start to turn tender.

Preheat the oven to 350°F.

Drain the milk from the pan and add the heavy cream, crème fraiche, salt, pepper, and nutmeg to the hot potatoes. Heat the cream-crème fraiche to just under a simmer (a few bubbles are fine) for 10 to 15 minutes, until the potatoes are very tender, but not falling apart.

Butter a large baking dish and spread the potato-cream mixture into the dish. Sprinkle the Gruyere cheese over the potatoes and bake for 20 to 25 minutes, until the potatoes are golden brown on top.

Cook's note: This is a great make-ahead side dish. Simply refrigerate it for up to 1 day before the final baking stage.
