The Mistake Everyone Makes with Mashed Potatoes — And How to Fix It

Mashed potatoes: creamy, fluffy, buttery perfection. They're a comfort food classic, a holiday table must-have, and the ultimate side dish. But for all their simplicity, there’s one mistake almost everyone makes when cooking them—and it could be ruining your mash without you even realizing it.

So what is it?

They boil their potatoes the wrong way.

It might sound minor, but the way you boil your potatoes can make or break your mashed potatoes. Let’s dive into why this mistake matters—and how to make your mash restaurant-worthy every time.

🥔 The Most Common Mistake: Starting with Boiling Water

Most people peel and chop their potatoes, then drop them into already-boiling water. It seems logical, right? After all, that’s how we cook pasta.

But here’s the problem:

❌ Dropping cold potatoes into hot water causes uneven cooking.

• The outside cooks too fast, becoming waterlogged and mushy.

• The inside stays firm, leading to lumps and inconsistent texture.

• The result? Mash that’s either gummy, watery, or oddly chunky—not the creamy dream you were hoping for.

✅ The Right Way: Start in Cold, Salted Water

To get evenly cooked, perfectly textured mashed potatoes, follow this golden rule:

Always start your potatoes in cold, salted water.

Here’s why:

• The potatoes heat gradually and evenly from the outside in.

• The salt flavors the potatoes from within, not just on the surface.

• You’ll get a smooth, fluffy mash with no lumps and no watery patches.

🍽️ Bonus Tips for Better Mashed Potatoes

Now that you’re boiling them right, take your mash to the next level with these pro tips:

1. Use the Right Potato

• Yukon Golds = creamy, buttery, slightly sweet

• Russets = fluffy and light, classic texture

• Avoid waxy potatoes (like red or fingerling) — they turn gluey when mashed.

2. Dry Them Out

Once drained, return the potatoes to the hot pot for a minute or two to evaporate excess moisture. This gives you a drier base that soaks up butter and cream better.

3. Warm Your Dairy

Cold milk or cream can cause your mash to seize up. Warm it before mixing in for ultra-smooth results.

4. Don’t Overmix

Using a blender or food processor can turn potatoes into a gummy mess. Stick to a hand masher or ricer for the best texture.

5. Add Butter First

Fat coats the starch and helps create a silky mouthfeel. Add butter before cream or milk for a luxurious finish.
