Making a side of homemade mashed potatoes just got so much easier. Just let the pressure cooker do all of the work for you! Also, when you make mashed potatoes in the Instant Pot instead of on your stove-top, it reduces your time in the kitchen by about 10 to 15 minutes.
When the potatoes are pressure cooked to perfection in the Instant Pot, the consistency is oh so soft and smooth. Mashing them doesn’t require sore arms afterwards because they’re incredibly tender.
Also, when you prepare this recipe in the Instant Pot, the garlic flavor really gets sealed in so much better than it would on your stove-top.
When it comes to comfort foods, I always prefer potatoes over pasta, and this potato side dish sits at the tip top of my list of favorites. I love serving it with hearty entrees like Prime Rib with Au Jus, especially during the colder winter months when I need something filling, flavorful, and wholly satisfying on my plate.
Tips For Making Mashed Potatoes In Instant Pot
- Do NOT replace the broth with water! Both chicken and vegetable broth lend so much flavor to the potatoes.
- Plan on serving these mashed potatoes with a beef entrée or gravy? Feel free to use Beef Stock instead of vegetable or chicken.
- Be very careful when you’re draining the water and mashing the potatoes as they will be quite hot.
- Want to save a little time? You can use quick release on the pressure cooker instead of natural release. Natural release normally takes an additional 10-15 minutes. As always, be careful because the steam is hot.
How To Make Instant Pot Mashed Potatoes
Prepare the potatoes: Peel and quarter the potatoes. You can also choose to leave the skins on if you prefer, just note that your final product will have an added texture to it.
If you choose to leave the skin on, be sure to rinse and scrub the potatoes well and make sure there’s no residue on them.
Add the ingredients to the pressure cooker: Place the prepared potatoes, pressed garlic, salt, and pepper in the Instant Pot (1). Pour in enough broth to cover the potatoes (2).
Pressure cook the potatoes: Close the lid and make sure it’s latched. Turn the valve to “seal” and set the Instant Pot to cook on high pressure cook mode for 15 minutes.
Carefully do a quick release. Make sure to press cancel first, then open the lid after all of the pressure has been released (3). Drain off the water, but be sure to save some for the mashed potatoes.
Add the final ingredients and mash: add the butter, about 1/4 cup of cooking broth, and about 1/4 cup of milk (4) to the potatoes. Mash the potatoes well and taste to see if you need more salt or black pepper. Add more milk if necessary until the desired consistency is achieved. Mash potatoes using a potato masher until smooth and fluffy (5).
Ingredient Tips and Substitutions
Potatoes – Russet potatoes are always the best choice for mashed potatoes because they are soft and fluffy and fall apart easy. Gold potatoes would be our second choice because they are medium starch. They are soft but still stay together a little more.
Whole milk – whole milk will give you creamier, richer sauce than low far options. If you need a lactose free options, you can use lactose free whole milk. For dairy free option, use almond milk or soy milk. (Note that oat milk is an option but it does tend to me sweet.)
Storing and Reheating Instructions
You can store your leftovers in an airtight container in the refrigerator. Stored properly, your mashed potatoes should stay fresh for up to 3-5 days. Note that some milks affect the shelf life and could be closer to 3 days.
To reheat mashed potatoes, you can reheat all of them at the same time in the oven or individual portions in the microwave. To reheat them all in the oven, spread the cold mashed potatoes in a baking dish in an even layer and drizzle 2-3 tablespoons of whole milk over the top.
Cover with a sheet of aluminum foil loosely and reheat at 350, about 15 minutes, just until hot in the center. Mix well and you can even add a couple of slices of butter on top to melt.
Do The Potatoes Need To Be Peeled?
No, you don’t have to peel them but you DO have to wash them well! If you want to keep your side dish rustic, you can keep the potato skin on and simply cut the potatoes and add them to the pot.
Make sure to wash and scrub the potatoes first though since they are usually covered in dirt.
Leaving potato skin on also preserves the nutrients that are in the potato skin.
