How To Make Mashed Potatoes In The Instant Pot
- Russet or gold potatoes — Peeled and quartered.
- Seasonings — Add sea salt and pepper to taste, but feel free to play around with other dried herbs or spices if desired.
- Butter — I generally use unsalted butter, but salted can be substituted in a pinch (be sure to go easy on the added salt when seasoning).
- Heavy cream — Half and half also works beautifully. You can also add some cream cheese or sour cream if you prefer.
- Fresh parsley — This garnish adds gorgeous color and fresh flavor to potatoes.
Prepare the potatoes:
- Peel and quarter potatoes.
- Place pieces in the instant pot or electric pressure cooker, cover with water or chicken broth and add a teaspoon of salt. Make sure you add enough liquid to cover the potatoes.

- Secure lid atop the instant pot and double check that the pressure valve is in the sealing position.
- Select the “Manual” or “Pressure Cook” button on the display panel (newer models won’t have a “Manual” button). Using the plus+/minus- buttons, add 8 minutes to the timer.
- Once potatoes have cooked for 8 minutes in high pressure, turn your instant pot off and carefully switch the pressure valve to the venting position for quick-release.
- Remove lid, drain water from potatoes and return them to the instant pot.
Season and mash:
- Add salt, ground black pepper, butter and heavy creamy to the Instant Pot. Mash using a immersion blender, potato masher or a potato ricer until potatoes are velvety smooth, uniform and lump free texture. The creamy consistency is very important to make the best Instant Pot mashed potatoes.

- In my opinion, the best potato to make Instant Pot Mashed Potatoes recipe are russet potatoes or Yukon gold potatoes.
- When quartering potatoes, try to cut chunks similar in size. This will help them to cook evenly.
- Feel free to add other dried or fresh herbs or spices to your potatoes. Try paprika, rosemary, chives, thyme, oregano, garlic powder, onion powder or Italian seasonings. You can also add a bay leaf to your instant pot while potatoes cook, just be sure to remove it before mashing.
- If you don’t have any unsalted butter, you can use salted. Just be careful not to add too much additional salt when seasoning your mash.
- It takes 10-15 minutes for an Instant Pot to build pressure. If you set the timer to 8 minutes and the pot doesn’t start cooking right away, don’t be alarmed. This is normal and the timer will begin ticking down after the pot has come up to pressure.
- If you prefer thinner potatoes, mash in an additional splash of cream. However, don’t overwork the potatoes or they may become gluey.
How To Store Leftover Instant Pot Mashed Potatoes
- Allow leftover potatoes to cool completely and transfer them to an airtight container. Store in the refrigerator for 3-4 days or freeze for up to 12 months.
- To reheat from frozen, start by using the defrost setting on your microwave. Once potatoes are softened, microwave on high until warmed through.
