When people talk about Michelin stars, they mostly talk about the staff-to-guest ratio, flawless presentation, and hard-to-find ingredients used in the most innovative ways. However, one of the most legendary chefs of French cooking, Joël Robuchon, earned his very first star thanks to one simple dish—mashed potatoes, or pommes purée.
I've dreamt about Joël Robuchon’s mashed potatoes ever since I tasted them at one of his L’Atelier establishments in New York, so here’s my interpretation of his signature dish. And if you’re planning on cooking this holiday staple this Thanksgiving, read on for the instructions.
How to make perfect mashed potatoes
Pro Tip: If you love smooth mashed potatoes, the best way to achieve that texture is with a potato ricer. By passing the cooked potatoes through a ricer, you break down even the smallest of lumps that would be left by a traditional potato masher.
A ricer also works faster and is gentler on the potatoes so you avoid the gluey texture that can result from over-mashing.
Tools you need
- A large pot or a Dutch oven
- A vegetable peeler
- A saucepan
- A potato ricer
- Optional: a sieve
Ingredients you need
- Six yukon gold potatoes
- 2 sticks of cold butter, cut into cubes (we recommend European butter like Beurre D'Isigny or Kerrygold, which have higher fat content)
- 1¼ cups milk
- Optional: 1/4 cup heavy cream or crème fraîche
- Kosher salt, to taste
Time Needed

Step-by-Step:
Step 1: Prepare and cook the potatoes
Scrub the potatoes but do not peel them. Place the potatoes in a heavy-bottomed stock pot or Dutch oven filled with enough water to submerge the potatoes. Add a pinch of salt. Bring to a boil with the lid on and cook the potatoes until tender—you can test by sticking the potatoes with a paring knife. If the knife cuts through easily, then they’re ready. The potatoes will take 20 to 25 minutes to cook.
Step 2: Let cool and peel the potatoes
Drain the potatoes and let cool slightly before peeling. When all the potatoes are cooled and peeled, put them through a potato ricer directly into the pot. Turn the heat to medium-low to remove any residual liquid. To dry more efficiently and avoid burning, stir the potatoes gently but frequently with a wooden spoon or rubber spatula.
Step 3: Add the butter
Use a spatula to achieve the right texture with your potatoes. We used a glass bowl for demonstration purposes, but you'll want to do this in a saucepan over low heat.
Turn the heat to low and gradually add the cold butter cubes. Stir the potatoes gently, using the back of your spoon to incorporate the cold butter until the mixture becomes smooth.
Step 4: Heat the milk and cream mixture
Combine the milk and cream or crème fraîche in a small saucepan. Slowly heat the mixture until little bubbles start to form on the edges, paying close attention that the mixture doesn't boil. Pour the hot milk mixture into the Dutch oven and stir to combine. If you want your mashed potatoes to be extra fine, run the mash through a sieve.
Step 5: Adjust seasoning and serve
Turn off the heat and add salt and black pepper to taste. Let cool slightly before serving. Enjoy!
