Just-baked potato gratin.

My sister, the doctor, lover of pies and Peeps, is hosting Thanksgiving this year. She has it all under control, sleeping arrangements organized, color-coded cooking timeline mapped out, and the menu finalized, promising her 12 guests a turkey, a spanakopita, cranberry sauce (not this one) and pie.

To help lighten her load, I’ve signed up to bring punch, stuffing, bread, and this potato gratin, a dish my mother has served at nearly every big holiday gathering for as long as I can remember, one that often steals the show no matter what it’s beside, turkey or otherwise.

It comes from Chez Panisse Vegetables, which offers a number of enticing combinations — potato with turnips or celery root or leeks or sweet potato — but we almost always use potatoes exclusively and keep the seasonings simple too: salt, pepper, thyme and just a dash of freshly grated nutmeg. Submerged in a mixture of equal parts heavy cream and chicken stock, topped with a mixture of Gruyère and parmesan cheeses, these potatoes emerge irresistibly crispy on top and creamy underneath.

This gratin couldn’t be easier to throw together, and you can’t mess it up. I promise. Hope all of your Thanksgiving preparations are going well.

My mother swears by red potatoes. I’ve learned not to question.

Description

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.

Notes:

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.


Ingredients

  • softened butter
  • 1 clove garlic, smashed
  • 3 lbs. red skinned potatoes, peeled (about 2 lbs. 10 oz. peeled)
  • kosher salt
  • pepper
  • 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 grated Gruyère cheese
  • 1/4 cup grated Parmigiano Reggiano cheese

Instructions

  1. Preheat oven to 375ºF. Rub an earthenware gratin dish (or 9×13-inch Pyrex) with smashed peeled garlic and butter.
  2. 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.
  3. 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.
