Instructions
Gather and prepare all ingredients.
Peel the potatoes and cut them into large cubes.
Place them in the Instant Pot, cover them with 6 cups of water, and sprinkle in 2 teaspoons of salt.
Seal the valve on the Instant Pot and turn it on pressure cook.
Set the timer for 12 minutes. It will take about 30 minutes to come to pressure, then cook the potatoes for 12 minutes.
After the timer goes off, turn off the Instant Pot and, using a wooden spoon or other utensil, carefully release the valve. Make sure not to burn yourself. Keep releasing until the steam has subsided.
Open the lid and, using oven mitts, grab the container and drain the potatoes in a colander.
Return the potatoes to the container and add the remaining salt, pepper, butter, and slowly add the milk.***
Using a potato masher, gently mash the potatoes until they reach your desired consistency. Do not over-mash, or they will get gummy.
*My store only had small russet potatoes, so it took 11 potatoes to make 4 pounds. If you find larger potatoes, it'll take less.**I used milk for the price and because I always have it on hand. You can use other dairy options if you already have them, such as heavy cream, half-and-half, or unsweetened non-dairy alternatives. Use dairy-free milk and butter to make this recipe vegan.***I add the warmed milk slowly at the end until the potatoes are soft and creamy, which is my preferred texture. You can adjust the amount to your liking. If the mashed potatoes sit for a bit and stiffen up, just stir in another splash of milk before serving.
