Mashed potatoes are one of those dishes that are so simple to make that many tend to just wing it. Often people just add a bit of butter…then some milk…then a little more milk…than more butter. And the results are usually passable, but far from mashed potato nirvana — hot, fluffy, and creamy. Sometimes, the dish devolves into an inedible mess, bland and flavorless, or thin and watery, or worst, an elastic ball of gluey potato dough.
Avoiding the Dreaded Glue Ball
The reason why the glue ball appears is usually because of overmixing. A lot of recipes suggest using hand mixer to get a smooth consistency. Don’t do this! If you beat the potatoes, you might open the starch granules in the potatoes, and that’s what makes them gluey and sticky. To be on the safe side, don’t use any electric mixing equipment to make your potatoes. You’re more likely to run into this problem with high to medium starch potatoes.
Another tip that I follow is to make sure that the butter is melted and the milk warm before adding them to the potatoes. Add the butter to the potatoes first. The butter coats the starch and makes it less likely to gum up. Heating the milk helps keep the potatoes warm for longer. Since mashed potatoes tend to lose their nice consistency when they cool, keeping them warm goes a long way to preserving your potatoes.
Avoiding Lumpy Potatoes
To get a smooth consistency, just use a potato ricer or a food mill. These handy tools will break down the potatoes enough so that a quick stir with butter and milk will create a smooth dish.
Personally, I think chunky mashed potatoes have a lot of personality. If you prefer them chunky, just use a potato masher to mash the potatoes.
Avoiding Watery Potatoes
This one is pretty simple, but it’s easy to do when you’re busy on Thanksgiving day. Don’t overcook the potatoes. Keep a timer on them and test them every couple of minutes when they’re close to done. You should be able to slide a fork into them with very little resistance. Drain them promptly, and finish making the dish promptly while the potatoes are still hot.
Butter & Milk
For really nice creamy mashed potatoes, you’re probably going to use a lot more butter and milk than you think. I like about 1 stick of butter and 1 cup of liquid (milk or half-and-half) to 2 pounds of potatoes. The richness of whole milk or half-and-half really adds to the dish. Yes, it will clog your arteries, but that’s why you only go all-out a couple of times a year.
So I guess the lesson here is if you want great mashed potatoes, give them a little respect. Just because a dish isn’t complicated to make, doesn’t mean you should shortcut it to mediocrity.








Hi Howie - Another thing I do to keep the mashed potatoes warm and most is to place the bowl or pot of mashed potatoes in another pot with a warm/hot water - in essense a water bath, and cover. It’ll keep the potatoes evenly warm and moist.

That’s a great tip, Kirk! Figuring out the best way to keep dishes while the turkey finishes is one of the great challenges of big holiday meals.
