Potatoes au Gratin
The humble potato gets the red carpet treatment in this easy yet luxurious recipe for potatoes au gratin. Sliced Yukon Gold or russet potatoes (you can use either, but don't use a combination as they cook at different rates) are layered with half-and-half or heavy cream, topped with butter and grated cheese, then baked until golden and bubbly. Feel free to play around: Add leeks, onions, garlic or more cheese between the layers. Experiment with fresh or dried herbs. It's incredibly adaptable and practically foolproof. Just don't forget to season with salt and pepper as you go. Like all potato dishes, it needs plenty of seasoning.
Yield: 4 to 6 servings
3 to 4 pounds potatoes, peeled and cut into ¼-inch slices
Kosher salt and black pepper
2 tablespoons unsalted butter
2 to 3 cups half-and-half or heavy cream
¼ cup grated Parmesan or Gruyère
Pinch of nutmeg (optional)
Heat oven to 400 degrees. Seasoning each layer with salt and pepper as you go, layer the potatoes in a 10- or 12-inch ovenproof skillet.
Dot the top with 2 tablespoons butter. Pour in half-and-half. (It should come about ¾ of the way to the top.)
Bring to a boil over medium-high heat. Reduce to low and cook for 10 minutes, uncovered, until the half-and-half has reduced by about half.
Transfer to the oven and bake until the top is golden brown, about 10 minutes. Reduce heat to 300 degrees and cook until the potatoes are fork tender and the top is nicely browned, about 8 minutes more. Top with grated cheese and return to the oven until the cheese is melty and golden brown, about 3 to 5 minutes. Sprinkle with a pinch of nutmeg, if using, and serve.
TIP: Typical Mark Bittman recipe - the base is simple and great as is but it is also endlessly customizable. I had whipping cream and no cheese, so I did a 3 parts cream, one part veg broth that I poured over the potatoes and butter. I tossed in some crushed garlic and added salt and pepper. I followed the cooking directions as written. My husband called these potatoes the lobster of vegetables. Thanks Mark! This recipe is a keeper.
I simply place unpeeled yukon sliced potatoes in a bowl with cream, wipe a casserole with halved garlic then arrange the sliced potatoes in layers, sprinkling each with salt, pepper and perhaps sauteed leeks. Then I pour the cream on, top with cheese and bake at 375 for an hour. For make ahead, I bake for 40 min. and then before serving bake for the additional 20-25 min. Otherwise just bake for about an hour.
Made this in my cast iron skillet and it was a hit for thanksgiving. I used Parmesan and a black truffle gruyere and added parsley, shallots, and garlic. I used cheese and the diced shallots/garlic in between every layer - absolutely divine. You’ll want to give it lots of time on the stove to reduce (30 minutes) before going in the oven. I also gave extra time after changing oven temp to 300 and finished in the broiler at the very end to get good color on top.
