I use my Instant Pot all the time to make mashed potatoes. It’s so much easier and faster than waiting for a full pot of water to boil. This recipe works for mashed potatoes or potato soup. Simply adjust the amount of milk you add.
Instant Pot Mashed Potatoes or Potato Soup Recipe:
I have an 8 quart Instant Pot, but you can make either of these recipes using a smaller size Instant Pot. Simply reduce the amount of potatoes that you use so that they don’t go above the max fill line on your IP liner.
8 Quart Instant Pot Recipe:
5-8 pounds of peeled potatoes
2 cups of water.
Place a wire trivet or mesh steamer basket inside your Instant Pot. Put all your peeled potatoes on top of the trivet or inside the basket. Add 2 cups of water. Seal the vent, set to High Pressure for 12 minutes for large potatoes, 10 minutes for medium potatoes, and 8 minutes for small potatoes. The warm setting should be off. The potatoes should be fork tender when done.

Drain the water from the Instant pot and remove the trivet or wire basket. Add your desired amounts of salt, pepper, butter, and milk and mash directly in the liner.
You just made mashed potatoes!
Instant Pot Potato Soup Recipe:
Follow the steps above but simply leave the water in the IP and add more milk or cream when you mash until your desired soupy texture is reached.
Allergy-friendly tip for those who need to add cooked milk:
If you have a milk sensitivity or allergy like my son, and you need to add cooked milk to your mashed potatoes so that they can eat it, then let me tell you about an Instant Pot tip that will make your lives so much easier. For years I’ve scaled milk on the stove to add to mashed potatoes. It’s such an inconvenient step, it takes so long, and I usually end up scrubbing burned milk off the bottom of my pan. Well, let the Instant Pot change your life on this one. Use the recipe above until the potatoes are cooked and you drain the 2 cups of water from the liner. At this point you can leave the potatoes on the trivet, and simply pour 2-4 cups of milk (I use about 4 for 8 pounds of potatoes) into your liner, put on the lid, and select the Yogurt setting. It will heat your milk to the pasteurization temperature of 160 degrees. Once your IP reads “Yogurt” your milk is heated, you can remove the trivet, and mash as normal. 😊
