Frequently Asked Questions (Mashed Potatoes with Broth)
Can I use any type of broth?
Yes. Chicken, vegetable, beef, or mushroom broth all work. Choose one that complements your main dish.
Do I need to add salt if using broth?
Broth contains salt, but you will likely still need some salt. Taste and adjust at the end.
Can I use this method for sweet potatoes?
Absolutely. Sweet potatoes simmered in vegetable broth are incredible. Use a little brown sugar or maple syrup to balance the savory notes.
How much broth do I need?
Enough to cover the potatoes by about ½ inch. For 3 lbs of potatoes, about 4 cups of broth.
Can I use milk instead of broth?
Yes, but watch carefully. Milk scorches easily. Simmer on low and stir occasionally. The result is ultra‑creamy.
Why are my mashed potatoes sticky?
Overmixing is the most common cause. Also, using waxy potatoes (red, new) will yield a sticky texture. Use Russets or Yukons.
Can I make mashed potatoes dairy‑free?
Yes. Use plant‑based butter and unsweetened oat milk or cashew cream. Simmer in vegetable broth. The result is still creamy.
How many calories are in a serving?
Using broth and moderate butter, a serving has about 250‑350 calories. Rich, satisfying, but not excessive.
Why Your Grandma Was Right (And Now You Will Be Too)
Grandma did not need a food blog to know that boiling potatoes in water is wasteful. She learned from her grandmother, who learned from hers. Cooking potatoes in broth or milk is an old‑world technique that adds flavor at every stage. It is simple, it is economical (you are not pouring flavor down the drain), and it produces mashed potatoes that need very little help to be delicious.
The next time you make mashed potatoes, do not reach for the salt shaker first. Reach for a box of broth. Your potatoes will absorb all that savory goodness, and you will need less butter and less salt. The result is healthier, more flavorful, and infinitely more satisfying.

The Bottom Line: Ditch the Water, Embrace the Broth
Boiling potatoes in water is not wrong – it is just not optimal. If you want mashed potatoes that are flavorful on their own, that do not rely on a pound of butter to taste good, that have a silky, rich texture and a savory depth that makes people say, “What is your secret?” – then you need to stop boiling in water and start simmering in broth.
Your grandma knew it. Now you know it. And once you try this method, you will never go back.
So the next time you make mashed potatoes, grab a carton of broth. Simmer, don’t boil. Save the liquid. Taste the difference. And when your family asks what you did, just smile and say, “It’s a family secret.”
