After peeling, cut them into thick slices. There is no need to dice them. The thick cut slices will cook easily in the instant pot. 

How many potatoes do you use per person for mashed potatoes?

It’s hard to determine how many potatoes to cook and mash. But a good rule of thumb is to prepare 1/2 pound of potatoes per person. Since the average potato in a bag of potatoes weighs about 6 ounces, you’d prepare 1 1/2 medium-sized potatoes per person. If you have large potatoes, you can prepare one potato per person.

Step 3 Pressure Cook the Potatoes

Why do mashed potatoes get gummy?

It’s all about the starch, that’s why mashed potatoes get gummy. When you mash the potatoes, the more you work with them, the gummier they will get. To keep your potatoes light and fluffy, don’t overwork them. 

Make sure your potatoes are fully cooked, and you have added enough milk and butter with them. Then mash as little as possible.

Just like overworked dough, potatoes can be overworked too.
