Instant Pot Garlic Parmesan Mashed Potatoes

  • Author: Sprinkles & Sea Salt


These Instant Pot Garlic Parmesan Mashed Potatoes are fast and easy to make in the Instant Pot. They are chunky, cheesy and garlicky goodness! Serve as a side dish with your favorite protein! 



2lbs red potatoes

water to cover potatoes (about 4 cups)

3 tsp salt, divided

4 tbsp butter, divided

1 shallot, chopped

6 cloves garlic, crushed

1/2 cup whole milk

1/4 cup heavy cream

1/4 cup sour cream

1 cup shredded parmesan cheese

1/2 tsp oregano

1/2 tsp garlic salt

dash of black pepper


Wash and dry potatoes

Dice potatoes into small chunks, leave skin on

Add potatoes to the pot of your Instant Pot

Cover with water and add 2 tsp salt, mix

Set Instant Pot to “Pressure Cook” high for 8 minutes

Lock top into place and switch pressure release valve to “sealing”

When the pressure cooking is done allow the pressure to natural release for 5 minutes, then switch the valve to “venting” to release any remaining pressure

When it’s safe to do so unlock and remove lid

Drain potatoes into a colander, set aside

Return pot to cooker and switch to “Sauté” mode high

Add 2 tbsp of butter, melt

Add the shallot, using a wooden spoon sauté for 2-3 minutes

Add the garlic, sauté another 1-2 minutes

Turn Instant Pot off

Add potatoes back to pot

Still working with your wooden spoon, add 2 tbsp butter, whole milk, heavy cream and sour cream

Mix vigorously, potatoes will break down and “mash”

At this point the potatoes will still have some chunks, that is what is intended for this recipe, but if you want them smooth use a hand masher or hand held mixer to whip* them smooth (optional step)

Add the parmesan cheese, 1 tsp salt, oregano, garlic salt and pepper, mix to combine

Serve immediately


*be careful not to over-whip or potatoes may turn gummy in texture
