Please STOP Boiling Potatoes in Water! My Grandma’s Secret Changed Everything About Mashed Potatoes

We all grew up watching our parents or grandparents toss peeled potatoes into a pot of boiling water before mashing them. It’s the classic way, right? But when my grandma saw me doing exactly that, she didn’t just correct me—she laughed.

And then she dropped a secret that changed everything I thought I knew about mashed potatoes.

 The Truth About Boiling in Water
Yes, boiling potatoes in water is the standard technique. But here’s what nobody tells you: you’re losing flavor. As the potatoes boil, their natural starch and subtle earthy taste seep out into the water—which you then pour down the drain. No wonder you need to add a ton of butter and salt afterward!

But my grandma? She had a better way.

 Grandma’s Secret: Boil Potatoes in MILK and BUTTER
Yes, milk and butter. Not only do the potatoes cook beautifully, but they also absorb all that creamy richness while boiling. The result? Potatoes that are already infused with flavor before you even start mashing.

 The Method (Grandma Style)
Here’s how she did it, and how I do it now too:

Ingredients:

2 lbs of russet or Yukon gold potatoes, peeled and cubed

4 cups of whole milk (or enough to cover the potatoes)

1 stick (½ cup) of unsalted butter

Salt to taste

Optional: garlic cloves, rosemary, or a bay leaf for extra flavor

Instructions:

Place cubed potatoes in a large pot.

Pour in milk until the potatoes are just covered.

Add the butter, a generous pinch of salt, and any optional herbs or garlic.

Bring the mixture to a gentle simmer (not a hard boil—milk can scald!).

Cook until potatoes are fork-tender, about 20–25 minutes.

Remove herbs (if used), and do not drain the liquid.

Mash the potatoes right in the pot, using the milk and butter they cooked in for extra creaminess.

Adjust seasoning and texture to taste. Add a little cream or more butter if needed.

 The Results?
Fluffy. Silky. Buttery. Rich. Mashed potatoes so flavorful you won’t need to drown them in gravy (unless you want to). My family now begs for them at every gathering—and I give all the credit to Grandma’s clever tip.

 Bonus Grandma Tip
If you want next-level flavor, try adding a spoonful of cream cheese or sour cream while mashing. And if you’re feeling adventurous, roast a head of garlic and blend it in. Heavenly!

Final Thoughts
Grandma always said, “Why cook flavor out, when you can cook it in?” Boiling potatoes in milk and butter might sound unconventional, but once you try it, you’ll never go back to plain water again.

So the next time you’re making mashed potatoes—ditch the water, channel your inner grandma, and let the creaminess speak for itself.
