Which Potatoes Are Best Mashed

Okay, let me set the scene. Last Thanksgiving, I was elbow-deep in a mountain of Russet potatoes, peeling like a man possessed. My grandma, a tiny woman with eyes that miss nothing, watched me from the kitchen stool and took a long sip of her tea.

“You’re using those for mashed potatoes?” she asked, with the same tone you’d use if I’d tried to mop the floor with a steak knife. I nodded, proud of my choice. She just sighed the sigh of a million disappointed ancestors.

That moment was a turning point. It took me years, several gluey batches, and one horrifically waxy disaster to understand what she meant. The truth is, not all potatoes are born equal when it comes to mashing. Some are destined for fries, some for salads, and only a few are worthy of that glorious, buttery throne.

The King of Mash: The Russet (Yes, Really)

Let’s start with the potato I was arrogantly peeling that day. The Russet Burbank, that big, starchy brown giant, is the shredded wheat of the potato world. It’s all rough, absorbent fluff inside.

This high starch content is its superpower. When you mash a Russet, the cells break apart easily and gobble up butter and cream like a sponge. The result is a light, fluffy cloud of a mash.

But—and this is a big, tragic, “I-swear-I-won’t-do-it-again” but—they are also the most vulnerable. Overwork them by even ten seconds with a mixer, and you get wallpaper paste. Treat them with the gentleness of a bomb disposal expert, and you are a god among cooks.

The Velvet Contender: Yukon Gold

If Russets are the fluffy cloud, Yukon Golds are the silken robe. These are my personal ride-or-die spuds. They have a medium starch content and a thin, delicate skin (which you can totally leave on if you’re feeling rebellious).

What makes them special? They are naturally buttery in flavor and color. You mash them with a little warm milk and a fat knob of butter, and you get something that looks like it’s already been stirred with gold.

The texture is dense and creamy, not airy like a Russet. It’s the kind of mash that holds a pool of gravy without breaking a sweat. You won’t get glue here, even if you get a little aggressive with the masher. They are the forgiving, sophisticated friend every dinner party needs.

The Waxy Imposters: Red & Fingerlings

I have to warn you about something. Look at a bag of Red Bliss or a pile of pretty Fingerling potatoes. They look perfect. They are liars.

These are waxy potatoes. They have a low starch content and hold their shape when boiled. This is fantastic for potato salad or roasting, but a disaster for mashing.

If you try to mash them, you will not get cream or fluff. You will get a bowl of sad, slick, dense lumps that resemble cold Play-Doh. The texture is gummy and never absorbs fat properly. Step away from the red potatoes. They are not for this job.

The Dark Horse: Purple Potatoes

Okay, so you want your mash to look like a unicorn vomited on a cloud? Use purple potatoes. They have a texture similar to Yukon Golds—creamy and satisfying.

The flavor is slightly earthier and almost nutty. The color will freak out your kids and impress your Instagram followers. But be warned: they turn a weird, dishwater gray if you add too much milk or acid.

They are a fun experiment for a Tuesday night, but for a holiday meal? Stick to the classics. Your guests will thank you for the familiar, golden comfort.

How to Save a Bad Mash (In Case of Emergency)

Let’s say you ignored me. You used waxies and now you have sadness in a bowl. What do you do?

First, don’t panic. You can add a ton of hot cream and melted butter to loosen the glue. Then, whip it hard with a whisk to break up the gummy network.

If that fails, fold in a handful of cream cheese. The fat and acidity will mask the texture a bit. You’ll have a “rustic, chunky” mash, which is just a diplomatic way of saying “I messed up.”

The Final Verdict

So, which one is best? It depends on your soul. Do you crave the light, ethereal fluff of a Russet? Be prepared for a careful, gentle process.

Or do you want the forgiving, buttery luxury of a Yukon Gold? That’s my vote. Every time. They are the Goldilocks of the mash world—not too starchy, not too waxy, just right.

My grandma? She uses a mix. Half Russet for fluff, half Yukon Gold for body. She said it “gives the mouth something to be happy about.” And she’s never, ever wrong. Now go forth and mash wisely.
