Michelin-Star Mashed Potatoes
Ingredients
- 2 lbs potatoes Russett, gold, and red potatoes all work great (the number of potatoes varies based on the type, so weigh them)
- 2 cups unsalted butter 4 sticks, cold and cut into small cubes (yes, this is half the weight of the potatoes)
- ½ cup whole milk warmed to about 110°F
- Salt to taste
- Pinch white pepper
Instructions
Cook the Potatoes
- Peel and cut the potatoes into even chunks.2 lbs potatoes
- Place them in a pot with cold, salted water. Bring to a gentle boil and cook until completely tender, about 20–25 minutes.
- Drain and return to the hot pot for 1–2 minutes to evaporate any moisture.
Purée Until Silky
- Pass the potatoes through a potato ricer twice back into the same pot. The double pass gives them a truly smooth texture—no lumps.
Mount with Butter
- Place the pot on low heat, using a hand mixer, whip the cold butter in slowly, a little at a time. Keep whipping until fully incorporated before adding more. This emulsifies the butter into the potato starch, making it silky and thick.2 cups unsalted butter
Add Warm Milk
- Once all the butter is incorporated, slowly whisk in the warm milk. The mixture should be smooth, glossy, and hold its shape on a spoon. If the mixture is too thick for your liking, add ¼ cup more warm milk until it reaches your desired consistency.½ cup whole milk
Season and Serve
- Taste and add salt (and optional white pepper). Serve immediately for the best texture.Salt to taste, Pinch white pepper
Notes
- Don’t skimp on the butter—this recipe is all about that ultra-luxurious texture.
- Using a fine mesh tamis instead of a ricer will take the smoothness to another level.
- For extra decadence, some chefs finish with a drizzle of cream or a touch of truffle oil.
What do you think of this recipe?Keep scrolling for the full recipe post. Please consider Leaving a Review!If you’ve ever wondered what would happen if mashed potatoes put on a tuxedo and walked into a fine dining restaurant, this is it. These ultra-rich, silky puréed potatoes are inspired by Joël Robuchon—yes, that Robuchon—and they live up to the hype. We’re talking equal parts potato and butter (you read that right), with a texture so smooth it could moonlight as skincare.
This isn’t your weeknight mash-and-dash situation. This is a “we’re going to savor every luxurious bite” kind of recipe. But don’t worry—it’s still totally doable at home with just a few ingredients and some deliberate technique. You’ll learn how to get that Michelin-starred silkiness, when to add your butter (spoiler: cold is key), and why your potato masher just won’t cut it this time.
What Makes These Potatoes So Special?
This recipe leans heavily into technique. The two big moves:
- Double-ricing: Passing the cooked potatoes through a ricer twice gives you that next-level smoothness. You can use a tamis if you’re fancy, but a ricer does a beautiful job.
- Cold butter, added slowly: It’s not a gimmick. Cold butter emulsifies into the warm potatoes much better than melted or softened butter, creating that rich, cohesive texture instead of an oily mess.
Can I Use Russets or Another Potato?
Yes. I have used Russets, Yukon Golds, and red potatoes (the red potatoes give you the perfect Sam’s mashed potato from Capital Grille). Any potato mixed with this much better will be transformed into a masterpiece.
Do I Really Need That Much Butter?
I mean, do you want the best mashed potatoes of your life, or just a reasonable side dish? Robuchon used nearly a 2:1 potato-to-butter ratio. We’re already being slightly conservative here. And trust me: the butter is what transforms them into something restaurant-worthy.
Still, if you want to scale it back, you can—just know the texture will change.
How to Serve Robuchon-Style Mashed Potatoes
These deserve to be the star of the plate. Serve them with:
- A perfectly grilled ribeye
- A rich, slow-braised pot roast
- Or honestly? Just a spoon.
If you’re making them for a dinner party, they hold well in a warm spot (like a covered bowl over a pot of hot water) for about 30 minutes. Just give them a good stir before serving. I love pairing these mashed potatoes with some soft and fluffy dinner rolls.
Leftovers & Reheating
If you somehow have leftovers:
- Store in an airtight container in the fridge for up to 3 days.
- Reheat gently on the stove with a splash of milk and a knob of butter to bring back the silky texture.
Rich, indulgent, and unapologetically buttery, these puréed potatoes are more than a side dish—they’re a flex. Go ahead, channel your inner Robuchon. Your dinner guests (or just your Tuesday night self) will thank you.
