Mashed Potatoes in the Instant Pot (No Drain)

Need a Hand
Prep Time15 mins
Cook Time15 mins


  • Instant Pot


  • 1.5 pounds golden potatoes
  • ½ Cup water
  • 1 clove garlic or 1 tsp better than bouillon roasted garlic base
  • 2 TBSP butter
  • ¼ Cup whole milk
  • ½ tsp kosher salt
  • tsp fresh ground pepper


To start:

  • This recipe works best in a 3 quart Instant Pot. If using a larger instant pot, please double the recipe or more to avoid the burn notice.
  • Rinse the potatoes thoroughly.
  • If you dislike skins in the mashed potatoes, and/or have time to peel, go ahead and peel the potatoes.
  • Then cut the potatoes into 1.5 inch chunks.
  • Don’t worry if not all pieces are 1.5 inches. This is common.
  • There will be a lot of starch (white moisture) on the potatoes, don’t re-rinse the potatoes.

Place in instant pot:

Put the lid on the instant pot:

  • Put the lid on and lock it.
  • Set the valve to sealing if you have a sealing setting.
  • Press “pressure cook” or “manual” or similar and then the +/- buttons until you get to 0010 for a 10 minutes cook time.
  • Once the pot reaches pressure, the timer will begin and then a beep will be sounded.
  • Set a timer for 15 minutes since the 10 minutes of cooking needs to happen, then 5 minutes of sitting.
  • Next, do a pressure release.
  • Do this either by turning the valve to venting or press the venting button, depending on your model.


  • Once the steam has been released, carefully remove the lid, and place it in the lid holder.
  • Carefully remove the instant pot liner and place on a hot pad or potholder.
  • Add the butter, milk, salt, and pepper to the liner.
  • Using a potato masher, mash the potatoes and mix with the butter and milk until smooth and well combined.
