Source: Chez Panisse Vegetables
I love the simplicity of the Chez Panisse Vegetables’s recipe, so I’ve written this one out exactly as it appears in the book and have offered some guidance on quantities/timing below:
“Rub an earthenware gratin dish with smashed peeled garlic and butter. Layer overlapping slices of potato cut 1/8-inch thick. Season with salt, pepper, and thyme leaves. Make another layer of potato slices and season again. Moisten with cream, cream and chicken stock, or milk to the top level of the top layer of potatoes. According to taste, sprinkle the top with grated Parmesan or Gruyère cheese, and distribute thin shavings of butter on top. Bake 45 minutes to 1 hour in a preheated oven at 375ºF until nicely browned.
If you need to make this ahead of time, just reheat covered with foil in a preheated 350ºF oven for about 15 to 20 minutes or until cream-stock mixture is bubbling. Uncover if necessary for 5 to 10 minutes to get the cheese bubbling.
- softened butter
- 1 clove garlic, smashed
- 3 lbs. red skinned potatoes, peeled (about 2 lbs. 10 oz. peeled)
- kosher salt
- 8 to 10 fresh thyme sprigs
- freshly grated nutmeg, optional
- 1.5 cups (or more or less) chicken stock
- 1.5 cups (or more or less) heavy cream
- 1 heaping cup (about 2 oz.) grated gruyère cheese
- 1/4 cup (less than 1 oz.) grated Parmigiano Reggiano cheese
- Preheat oven to 375ºF. Rub an earthenware gratin dish (or 9×13-inch Pyrex) with smashed peeled garlic and butter.
- Using a mandoline or knife, cut potatoes 1/8-inch thick and layer overlapping slices in the prepared pan. Season generously with salt, pepper, and thyme leaves (no need to chop — just pull and scatter). Lightly grate nutmeg over top. Make another layer of potato slices and season again in the same manner.
- Cover the potatoes with the stock and cream — you may need more to allow the liquid to get to the top level of the top layer of potatoes. Sprinkle the top with the grated cheeses. Bake 45 minutes to 1 hour, checking after 40 minutes or so to make sure the potatoes are not browning too quickly. If they are browning too quickly, cover the pan with foil and continue baking until the potatoes are tender and the top is nicely browned. You can also turn the temperature down to 350ºF if necessary.
