This 31-Michelin-Star Chef’s Mashed Potatoes Are So Good, They’re World-Famous

When autumn arrives, few dishes bring comfort quite like creamy mashed potatoes, a side that warms both body and soul.

But achieving restaurant-level perfection at home takes more than just boiling and mashing.
French chef Joël Robuchon, who held an astonishing 31 Michelin stars, revealed the secret that made his mashed potatoes world-famous.

Here’s how to recreate it in your own kitchen.

The Golden Rule of Perfection

Robuchon’s secret lies in the ratios. The butter and milk should each equal half the weight of the potatoes.
For 1 kilogram of potatoes, you’ll need 250 g of cold unsalted butter and 250 ml of hot milk.
It sounds indulgent, but that’s exactly what makes the texture irresistibly smooth and rich.

The Power of Technique

Robuchon’s method includes two key techniques:
– Boil the potatoes with their skins on to preserve flavor and starch.
– Press through a fine sieve or ricer for a silky, lump-free finish.
Together, these create that signature velvety texture.

The World-Famous Recipe

Ingredients:
– 1 kg Le Ratte potatoes (or Yukon Gold, Maris Piper, Russet)
– 250 g cold unsalted butter, cubed
– 250 ml hot milk
– Sea salt to taste
Le Ratte potatoes are ideal thanks to their creamy, dense flesh that yields perfectly smooth mash.

Step One: Boil to Perfection

Place the unpeeled potatoes in a pot of cold, salted water.
Bring to a simmer and cook for about 30 minutes, until tender when pierced with a knife.
Drain, then let them cool slightly. They should remain warm when peeled.

Step Two: Peel While Warm

Cut a shallow slit along each potato and gently remove the peel while holding it with a paper towel.
Peeling warm potatoes preserves their natural starch and keeps them from absorbing excess water.

Step Three: Mash by Hand

Use a potato ricer or fine sieve to mash the potatoes directly into a warm pan over low heat.
Avoid using a blender or food processor, overworking the starch will make the mash gluey, not silky.

Step Four: Add the Butter Slowly

With the pan on low heat, gradually fold in the cold butter cubes, stirring constantly until fully absorbed.
The cold butter helps emulsify the texture, making the mash glossy and smooth.

Step Five: Blend in the Hot Milk

Next, slowly whisk in the hot milk, beating briskly to keep the texture airy and light.
Warm milk ensures a creamy consistency without separating the fats.

Step Six: Season to Perfection

Add sea salt to taste and adjust for balance.
For a twist, try infusing the milk with garlic or herbs before mixing for a subtle, aromatic depth.

Finishing Touches

“Honestly, this is the best mashed potato I’ve ever eaten,” says Chef Fenix, who recreated Robuchon’s recipe on TikTok.
“The texture is like velvet – impossibly rich and elegant.”

Tips for Success

✨ Don’t overcook – waterlogged potatoes make soggy mash.
✨ Use high-starch potatoes for fluffiness.
✨ For a lighter version, reduce butter to 150 g per kilo but keep the milk ratio.
✨ Add Parmesan, roasted garlic, or herbs to make it your own.
