Why Yukon Golds? Their high starch content and thin skin create the creamiest texture. Russets work, but Yukon Golds are the gold standard.


The Method: Simple Steps, Perfect Results

Step 1: Prep the Potatoes

Peel the potatoes and cut them into even 1½-inch chunks. Uniform size ensures even cooking.

Step 2: Boil

Place potatoes in a large pot and cover with cold water by about 1 inch. Add 1 tablespoon salt. (Yes, the water should taste well-salted—this seasons the potatoes from within.)

Bring to a boil over high heat, then reduce to a simmer. Cook for 15-20 minutes, until potatoes are fork-tender (a knife should slide in with no resistance).

Step 3: Drain and Dry

Drain potatoes thoroughly. Return them to the pot over low heat for 1-2 minutes, shaking gently, to evaporate any excess moisture. This step is crucial for creamy (not watery) potatoes.

Step 4: Rice or Mash

For the absolute smoothest texture, pass potatoes through a ricer or food mill into a large bowl. (If you don't have one, a masher works—just be gentle and don't overwork.)

Step 5: Add Butter

Add the cubed butter to the hot potatoes. Stir gently until melted and incorporated.

Step 6: Add Cream

Slowly pour in the warm cream, stirring gently until absorbed. The potatoes will look almost soupy at this point—don't worry, they'll thicken.

Step 7: Season

Add white pepper and additional salt to taste. Stir gently to combine.

Step 8: Adjust Consistency

If needed, add warm milk a little at a time until you reach your desired consistency.

Step 9: Serve

Transfer to a warmed serving bowl, create a slight well in the center, and add a pat of butter if desired. Serve immediately.


Pro-Tips for Mashed Potato Perfection

1. Don't Overwork the Potatoes
Over-mixing releases too much starch and turns them gluey. Stir gently, just until combined.

2. Warm Your Dairy
Cold cream or milk will cool down your potatoes. Warm them gently before adding.

3. Salt the Water
This is your only chance to season the potatoes from within. Don't skip it.

4. Dry the Potatoes
That extra minute over low heat after draining removes excess water that would otherwise make your potatoes watery.

5. Use a Ricer
If you want truly velvety, lump-free potatoes, invest in a ricer. It's a game-changer.

6. Keep Them Warm
Mashed potatoes cool quickly. Transfer to a warmed bowl, cover with foil, and place over a pot of simmering water to keep warm.

Your Mashed Potato Questions, Answered

Can I use russet potatoes instead?
Yes! Russets make fluffy, light mashed potatoes. They're slightly less creamy than Yukon Golds but still excellent.

My potatoes are gluey. What went wrong?
Either overworked or over-processed (like in a food processor). Next time, use a ricer and stir gently.

Can I peel the potatoes ahead of time?
Yes, but submerge them in cold water to prevent browning. Drain and dry before cooking.

Can I freeze mashed potatoes?
Yes! Portion into freezer-safe containers, cool completely, and freeze for up to 3 months. Thaw in refrigerator and reheat gently with a splash of warm milk.

What's the best way to keep them warm for a crowd?
Transfer to a slow cooker on WARM. Stir occasionally and add warm milk if they thicken.

Can I make these dairy-free?
Yes! Use plant-based butter and unsweetened oat milk or almond milk. Add a little extra fat for richness.
