Yes, that’s potato gratins in the plural – not singular. I made these last weekend. Not only are they very cute in their individual ramekins, they are also elegantly and cleverly portioned. This ensures that you will be less likely to find yourself gobbling up half a baking dish of gratinéed potatoes or wrestling your child for the last crunchy cheesy corner stuck to the rim. Just saying. It happens.
A mandoline works best for thinly slicing the potatoes. Keep the skins on for extra nutrients and texture to balance out all of the cheesy goodness. Makes 8.
2 cups full-fat sour cream
2 garlic cloves, minced
Freshly ground black pepper
1 1/2 pounds small white, Yellow Finn or Yukon Gold potatoes, washed, very thinly sliced – no more than 1/8 inch thick
8 ounces grated Gruyère cheese
Preheat oven to 350 F. Butter 8 3/4-cup ramekins. Whisk sour cream, garlic, 1 teaspoon salt and 1 teaspoon freshly ground black pepper together in a bowl. Arrange 2 layers of potatoes overlapping in ramekins. Top with a heaping teaspoon of sour cream, spreading to cover the potatoes. Sprinkle with cheese. Repeat layering process, occasionally sprinkling with additional salt and pepper, until ramekins are full, gently pressing down on each layer. Finish with a layer of sour cream and grated cheeese. Arrange ramekins on a baking tray. Bake until potatoes are tender and top is brown and bubbling, about 1 hour. (If top browns before potatoes are fully cooked, lightly cover with foil to prevent burning.) Serve hot.
