What Are Dauphinoise Potatoes?

Potatoes don’t get any more luscious than in this classic French style of serving potatoes. 

But, what’s to love most, is that this elegant potato dish is easy to assemble ahead, bake just before serving or bake a day in advance.

Also, using a biscuit cutter, to press out individual portions in advance, makes for elegant serving, for a more special occasion plate.

Holiday Cheesy Potatoes Dauphinoise

Who makes a huge serving of mashed potatoes for Thanksgiving, Christmas or any other holiday meal?

Then you know the importance of serving a fabulous potato dish that doesn’t require so much extra work, those last moments before serving.

Mashed potatoes do require last minute work while these elegant potatoes do not!

Why stand there and mash potatoes, mash and mash while other things on the stove, and in the oven need your attention?

Dauphinoise Potatoes

Potatoes au Gratin, or Dauphinoise potatoes, are the perfect solution for a busy cook because they can be assembled a day in advance and baked to a crispy edge, creamy inside, perfection.

The only thing to do once baked, is slice or scoop and serve. 

These beautifully constructed, layered potatoes look elegant when pressed with a biscuit cutter for individual servings.

Do your holiday mashed potatoes start to dry out the longer they sit on your lovely holiday spread?

These creamy cheesy potatoes won’t!

Cheesy potatoes au gratin can be done in a pie dish, or a large baking pan and baked a day ahead.

The baked crispy cheese edges warm beautifully the next day or several days later. Make these in small individual serving baking dishes or for a large crowd, either way the portions are easy to arrange or rearrange.

Potatoes Numerous Ways

Don’t get me wrong, when I serve Dauphinoise potatoes, they often steal the show away from the protein options on the plate.

However, these beauties are easily challenged by a variety of other favorite potato dishes.

After all, who doesn’t love the humble potato!

Servings: 6 servings


  • Large baking dish
  • Mandolin to thinly slice potatoes


  • 3 Large russet potatoes thinly sliced
  • 1 tbsp Coarse salt for soaking
  • 6 oz Gruyere cheese grated
  • 2 cups Heavy Cream or whole milk
  • Sea Salt to taste

  • 3 Garlic cloves crushed
  • 1 tsp Dried thyme
  • Fresh thyme several sprigs
  • 1 tbsp Unsalted Butter
  • pinch Nutmeg


  • Preheat oven to 350
  • With a mandolin, slice the potatoes very thin. Unpeeled for a rustic dish, peeled for a more refined dish.
  • Place the potatoes in a large bowl of salted water to remove some of the starch, while preparing the remaining ingredients.
  • Rub the butter all around the bottom and sides of the baking dish.
  • Place the milk or cream, garlic and dried thyme in a pot and bring to a simmer.
  • Drain the potatoes and pat dry.
    Place one layer of potatoes on the bottom of the pan. Salt and pepper to taste and sprinkle a little cheese.
    Continue doing the same, layer after layer, until you have stacked the baking dish with many layers of potatoes and cheese.
  • Take the warmed cream mixture and gently pour across all the layers of potatoes, allowing to seep into each layer.
  • Make one last sprinkle of cheese on top with a generous pinch of nutmeg.
  • Bake 1 hour or until golden on top.



  • Can be served straight from the pan, or use a biscuit cutter, when potatoes have cooled, to create individual servings. Place on a parchment paper lined sheet pan and rewarm at 325 for 10 minutes.
