You could add the following:

  • Chives

  • Garlic salt

Did you know the type of potato you use makes a huge difference in how your mashed potatoes come out? It is true.

Have you ever had really glue-y mashed potatoes before? You probably used the wrong potatoes. Red potatoes, for example, are great for baking, or roasting, but not so good for mashed potatoes.

The best option for light, fluffy, and flavorful mashed potatoes are russet.

How you cook your potatoes matter too. Instant Pot is my new favorite way, but Slow Cooker Mashed Potatoes are pretty amazing as well.

The thing with the Instant Pot is I am always pretty busy, and running behind. This means I don’t always think ahead when it comes to dinner, and the Instant Pot makes it quick and easy.

It literally takes longer to peel the potatoes and cut into chunks than to cook them in the Instant Pot. Amazing right? So if you are at all like me, and forget to get things started before you head out for the day, utilize the pressure cooker and enjoy!

Instant Pot Mashed Potatoes

Simple Instant Pot Mashed Potatoes, are the easiest, fastest, fluffiest mashed potatoes you will ever make.

Did you make this recipe?


  • 5 pounds russet potatoes, peeled and chunked
  • Water, approximately 1 1/2 cups, you need an inch in the bottom of your pressure cooker, so amount may vary depending on the size of pressure cooker you use.
  • 1 tsp salt
  • 1/2 cup milk
  • 1/4 cup butter
  • Salt and Pepper to taste



  1. Fill Instant Pot pot with 1 inch of water in the bottom.
  2. Peel and chop the russet potatoes.
  3. Place potatoes in an Instant Pot.
  4. Add the teaspoon of salt.
  5. Put the lid on top of the Instant Pot, and turn to close the lid.
  6. Set the valve to “sealing”.
  7. Press the MANUAL button. Press the +/- button to set to 12 minutes.
  8. Let the IP do it’s job. It will take a little while for the Instant Pot to come to pressure. At which time it will start counting down.
  9. When it counts to zero, it should beep. At this time, place a cloth over the valve/vent, and turn to venting. The cloth will protect you from any water that might spit out the top.
  10. Once the pressure cooker has vented, open it, and add the milk and butter, as well as salt and pepper to taste.
  11. Use a potato masher to mash the potatoes right in the pot.
