Instant Pot mashed potatoes taste exactly the same as regular mashed potatoes, there is no difference in taste whatsoever.  Follow my mashed potatoes secrets to create the most amazing mashed potatoes ever!

Perfect Mashed Potatoes

Before I got myself an Instant Pot, I discovered crockpot mashed potatoes.  Making potatoes in the slow cooker is also hassle-free and you don’t need to drain them!  However, it takes hours for potatoes to cook in the crockpot, and only 10 minutes in the Instant Pot!

Instant Pot Cooking Potatoes

So here’s the evolution of my mashed potato cooking methods: I originally learned how to make them traditionally in a pot of boiling water on the stove, then discovered how to make them in a crockpot and switched to the crockpot method.  When I got an Instant Pot and tried making mashed potatoes in it, I never looked back!  Now if I want mashed potatoes, I make them in the Instant Pot 100% of the time!

How To Make Mashed Potatoes In The Instant Pot

Making mashed potatoes in the Instant Pot is really easy! Just peel the potatoes and cut them into quarters.  Put the potatoes in the Instant Pot and pour 1 cup of chicken or vegetable stock in the pot (or water).  Chicken stock makes the mashed potatoes more flavorful!

Press the “Manual” or “Pressure Cook” button on the Instant Pot and set the time for 10 minutes.  After it finishes cooking, do the Quick Release of the steam.

How To Make Mashed Potatoes In The Instant Pot

Mash the cooked potatoes directly in the pot with a potato masher.  Add butter, milk, salt and pepper and other desired flavorings to taste.  You can add minced garlic too for garlic mashed potatoes – yum!  I also like to garnish mine with chopped green onions!

If your potatoes are small potatoes with a thin skin, you don’t even have to peel them!  Just cook them and mash them with the skin and all! How’s that for a lazy recipe?
