French Mashed Potato (Pomme Purée)

This is the classic French mashed potato you will find in many high-quality French restaurants, often called pomme purée. It is smooth, buttery, and very indulgent, with a texture that feels refined and luxurious.

Despite using only three ingredients, the result is elegant and makes the perfect side dish for meats, poultry, or fish. You can also adjust the consistency to your liking, making it as thin or as thick as you prefer by varying the amount of milk.

Ingredient Notes

Potatoes: Use a waxy type of potato like Yukon Gold or Maris Piper. These will give you a creamy mash with good texture. You can also use Ratte du Touquet, which are the classic French potatoes used in high-end French restaurants.

Butter: Adds richness and depth of flavor. Cube the butter so it melts evenly when mixed with the hot potatoes.

Milk: Used to thin the mash to your preferred consistency. You can omit it for a denser, mashed potato, or add more for a thinner pomme purée style.

Salt: Season the potatoes properly. Add it to the cooking water so the potatoes absorb flavor as they cook, then adjust again at the end to taste.

Chef Tips

Keep Ingredients Hot: Place the butter and milk into the warm pot before ricing the potatoes. After ricing, work quickly to fold everything together while the potatoes are still hot. If the mixture cools down, it won’t combine smoothly and can turn lumpy.

Mix Gently: Once the potatoes are combined with the butter and milk, fold carefully rather than stirring vigorously. Gentle mixing prevents excess starch from being released, which keeps the mashed potatoes silky instead of gluey.

How to Adjust the Consistency: To thin the mash, stir in a little more warm milk until it reaches your desired creaminess. To thicken, return the potatoes to the stove and cook gently over medium-low heat, stirring regularly until the texture firms up.

Use a Potato Ricer (and Fine Sieve for Extra Smoothness): A potato ricer breaks the potatoes down into a fine texture that gives a smooth mash. However, for an even silkier result, pass the riced potatoes through a fine sieve a second time, pressing gently with the back of a ladle or spatula. This will give you ultra-smooth, restaurant-style mashed potatoes.

Step by Step Instructions

1) Fill a large pot with water. Peel the potatoes, placing them in the water as you go to prevent browning. Once all the potatoes are peeled, drain the water and chop the potatoes into even pieces.

2) Refill the pot with generously salted water and add the chopped potatoes. Bring to a boil, then reduce to a simmer and cook for 20–25 minutes, until softened. Drain well.

3) Place the cubed butter and milk into the hot empty pot. Using a potato ricer, press the drained potatoes back into the pot over the butter and milk.

4) Gently mix until smooth and creamy. Season to taste with salt.

Storage and Leftovers

Refrigerator: Store the mashed potatoes in an airtight container for up to 3 days.

Freezer: The mashed potatoes can be frozen, although the butter in the mash will separate once frozen and thawed. If you freeze it, I recommend reheating in a saucepan over medium-low heat, mixing as it warms so the butter reincorporates back into the potatoes.

Reheating

Saucepan method: Place the mashed potato in a saucepan over medium-low heat. Stir regularly as it warms so the texture becomes smooth and creamy again. If you want a looser consistency, add a small splash of milk. If it feels too thin, continue cooking gently until it thickens.

Microwave method: Transfer the mashed potatoes to a microwave-safe dish and cover it. Heat in short intervals, stirring between each one until hot.
