Step 1: Wash and scrub the potatoes under running water to clean. Slice the potatoes into ½ inch (1.2cm) rounds so that they cook evenly.
Step 2: Add the sliced potatoes and water to your Instant Pot, push the potatoes down so that the water completely covers them. Cover and pressure cook for 10 minutes on high pressure.
Step 3: Release the pressure valve on top of your Instant Pot and wait for the pin to drop down. Then remove and drain the potatoes. Return the empty Instant Pot inner pot to the Instant Pot, rinsed out with water or wiped clean with paper towel.
Optional: Press Saute on your Instant Pot and add the butter. Once the butter has melted, add the garlic cloves and herbs and mix to allow the flavors to infuse the butter for 5 minutes.
Step 4: Remove the large garlic pieces and herbs. Return the potatoes to the pot. Add the milk and salt and pepper. Mash the potatoes until completely smooth and creamy.
Hint: Make sure you completely mash the potatoes as any lumps will make the mash less fluffy and creamy. Mash for a few minutes and you can mash any stubborn potatoes pieces with a fork if necessary.
Step 5: Taste the mash and adjust the seasonings if needed, you can also add more milk or cream to the mash to adjust the consistency.
Step 6: Serve the mashed potatoes with pats of butter and fresh herbs to garnish.
👨🏻🍳 Questions & Answers
Nope! No need to peel your potatoes for Instant Pot mash. The high pressure softens the potatoes and their skins so when they are mashed together, the skins almost disappear into the mash. Saves you time and is healthier too!
Equally sized pieces of potatoes will cook faster in the Instant Pot. 10 - 15 minutes of pressure cooking is usually enough to soften potatoes completely.
Yes, you can make dairy-free mashed potatoes. You can substitute the milk with vegan unsweetened milk. Cashew milk or soy milk are thicker and would work for this recipe. Substitute the butter with vegan butter and this recipe is then dairy-free and vegan-friendly!
There is no need to let potatoes cool before mashing them. The heat can make them easier to mash than if they cooled slightly. This recipe leaves the potatoes to cool slightly while the garlic butter is made but it doesn't affect this recipe.
There are a few substitutions that can be made in order to make this recipe suit certain diets.

If you want to spice up your regular mashed potatoes, why not give these variations a try?
- Spicy - add chili pepper flakes to the butter while infusing it with the garlic and herbs for a spicier mashed potato
- Extra creamy - for extra creamy mashed potatoes, add some cream along with the milk or substitute the milk for half and half. Also make sure to mash the potatoes really well to get them super creamy and soft
- Bacon and Cheese Version - Fry up some crispy bacon bits and sprinkle them over the mash along with some shredded cheddar cheese. You'll add a tonne of flavor to the mash along with some crunch too!
🥔 Best Potatoes for Mash
Choosing the right potato for your mash actually makes a huge difference to the texture and taste of your mashed potatoes. Usually. Russet potatoes and Yukon Gold potatoes are used for mashing.
Russet potatoes are considered the best potatoes for making mash, as they have high starch contents which make the fluffiest mash.
Yukon Gold potatoes make for a more classic and dense mashed potatoes as they have a slightly lower starch content. They will also make your mash more creamy as they have a delicate creamy taste to them. You will most likely have Yukon Golds lying around as they are a good all-purpose potato for all dishes.
Making instant pot mashed potatoes with skin
We leave the skin on the potatoes as it makes almost no difference to the taste and texture of the dish but it shaves off (pun definitely intended!) all that peeling of potatoes that I never have time for!
As long as the potatoes are cooked for long enough the skins will be super soft and almost disappear into the mash when you are mashing it up.
Potato skins are also a great source of some vitamins, fibre and Iron! All the more reason to keep them in your meal.
This recipe has been developed and tested using an 6 quart (5.5 L) Instant Pot. I would recommend using an Instant Pot as they make the cooking of the potatoes such a breeze.
You can also use any pressure cooker for this recipe, the mashed potatoes will turn out just as creamy and delicious!
If you want to make this recipe on the stove top, then follow these steps:
- add 1 - 2 cups of water as needed while cooking the potatoes until fork tender
- drain the potatoes as normal and make the optional garlic butter on the stove top
- you then make the mash in the same pot the potatoes were cooked in!
Store any leftover mash in the refrigerator for up to 3 days in an airtight container.
This recipe does not stand up well to freezing. It is best served immediately or for up to three days if stored correctly.
To reheat the mashed potatoes, heat on the stove top or use a microwave and heat for a few minutes at a time, stirring after each heating cycle. You might need to add more milk as the mash heats up to help smooth it out.
Making the optional garlic herb butter for this mashed potatoes recipe is really worth that tiny extra step. You just have to infuse the butter with the garlic and fresh herbs for a few minutes to add a delicious dose of flavor to your mash!
