Three Most Common Mashed Potato Mistakes
Like I mentioned before, surprisingly mashed potatoes can be a difficult thing to get just right. But as long as you watch out for these commonly made mistakes there is no need to stress.
Over Cooking
More than once I have boiled my potatoes for too long and had them turn into a watery potato mush after mashing, and sadly there really is no way to come back from that. Or in fear of cooking too long, I’ve on occasion under cooked my potatoes. In which case when it comes time to mash them not only do I get a massive arm work out, but I also end up with lumpy potatoes (and not the good kind of lumps, I am talking raw chunks). And ain’t no body got time for that. But with the Instant Pot there is no need to worry. As long as you follow the instructions you have perfectly cooked potatoes every single time!
Under Seasoned
We’ve all had them before … bland flavorless mashed potatoes. And while they aren’t the worse dish in the world well flavored potatoes are so much better. This recipe guarantees perfect flavor every time! Perfect balance of creamy, buttery with a hint of garlic. Flavor truly fit for any meal accompaniment.
Keeping It Hot
Another issue with mashed potatoes I was unable to master until I began using the Instant Pot was by the time I put them out on the table my potatoes were always lukewarm. It seemed impossible to get them to the table piping hot. As delicious as potatoes are there is nothing quite like hot, steamy mashed potatoes. With a few simple tips though it is easy to keep these bad boys nice and hot till ready to serve!
After your potatoes are cooked and you drain them be sure NOT to rinse the pot before returning the potatoes to it. Next you will want to be sure you place the inner pot back into the pressure cooker. This helps keep the pot insulated which is how we ensure hot potatoes when serving. Mash your potatoes and season them right there in the Instant Pot inner pot. These steps will help the potatoes to stay piping hot until ready to serve.

Pro Chef – Mom Hack
Before cooking in the Instant Pot be sure to rinse the sliced potatoes and drain off any excess water. This simple step helps to remove excess starch buildup that will happen while boiling. Trust me, this may not seem essential but if you don’t do it you will open your pressure cooker to find a frothy grey ring around the waterline. Save yourself the trouble and give your sliced potatoes a quick rinse before adding salt and water to cook.

Whipped or Mashed – That is the Question
As you will see in the video I prefer to use a handheld mixer which technically means that my potatoes are whipped potatoes versus a more traditional mashed potato. If looking for a true mashed potato you can use a potato masher, ricer or fork. Any of these methods work great, it just comes down to your preference and the desired texture you want!
