How to make Mashed Potatoes in the Instant Pot
Instant Pot Mashed Potatoes are so quick and easy to make! Here is what you will need to do to prepare these creamy mashed potatoes.
Step 1: Prepare the potatoes
Start off by cleaning, peeling and slicing your potatoes. I like to slice mine into 1/2 inch thick rounds.
Step 2: Cook in Instant Pot
Add the potatoes, water and salt to the Instant Pot. Secure the lid and turn the pot to high pressure/manual. Next, set the timer for 10 minutes. It will take the pressure cooker about 7 to 10 minutes to come to full pressure before the 10 minutes starts counting down, hence the 20-minute total cook time. When the 10 minutes is up and the pot beeps, do a manual release of the pressure.
Step 3: Mash the Potatoes
Add the butter and milk to the potatoes. Then, blend or mash the potatoes right in the Instant Pot until they are smooth and creamy. Season with salt and pepper, serve and enjoy!
Tips for Mashed Potatoes:
- A great way to add flavor to these potatoes is to add ¼ cup of sour cream when mixing in the milk.
- Do not be afraid to mash these potatoes instead of whipping them. That is totally your preference!
- If you wish, you can swap the russet potatoes for yukon golds or even red potatoes. Just be sure to have about 3 lbs of them.
- No need to drain these potatoes like you would for a stove method. Just another reason why they’re so quick!
