Mashed Potatoes in the Instant Pot for one or a crowd (Up to 5 pounds at once!)

One of my favorite things about the Instant Pot is the fact that time doesn’t change when cooking larger quantities. So you can follow this ‘recipe’ as a guideline for 1 potato or an entire 5 lb bag of potatoes!

Sometimes I just get a hankering for a big ol’ bowl of mashed potatoes and gravy. If you haven’t made some sort of protein to go along with your mashed potatoes, you can actually easily make your own chicken gravy from scratch without drippings.

Use either a potato masher or an electric hand mixer to mash the potatoes until they are no longer lumpy.

Be careful to insure you do not over mash/mix the potatoes. Over mashed potatoes will turn gluey. Only mash or mix just until it is no longer lumpy.

Reheating Mashed Potatoes in the Instant Pot

Reheating mashed potatoes in the Instant Pot is such an easy thing to do. Place your mashed potatoes in the liner of your Instant Pot a few hours before you want to serve them. Turn your Instant Pot onto the highest slow cook setting. Let your mashed potatoes sit and warm up, giving them a stir every 30 minutes or so until the mashed potatoes have heated through. Mashed potatoes do tend to dry out while reheating, so you may need to add a splash of milk to fluff them back up.

Instant Pot Mashed Potato Recipe Variations

  • Buttermilk and garlic
  • cream cheese and chives,
  • bbq sauce and bacon (with lots of cheese, of course)
  • and you just can’t go wrong with the classic butter, cream, salt and pepper.

The trick to good mashed potatoes is cooking. your potatoes thoroughly, adding butter first, mashing by hand and then slowly adding in a little liquid of your choice at a time, mixing until the liquid is just mixed in. Do not over mix and you should be golden!

  1. I cook mine in chicken broth with a few cloves of garlic!
    Sometimes after they are cooked I will add some cream cheese with the milk or heavy cream

  2. Hi Nicole! Yes, you can definitely make them ahead of time. I would just reheat in either your Instant Pot (on sauté low and then keep warm) or in your crock pot on high, stirring every 30 minutes or so.

  3. Hi. About how long does it take for 5lbs of potatoes to come to pressure? Cooking for a crowd for Christmas. Thank you.

  4. 5 stars
    Very excited to try this recipe! However, I only have a 3qt IP since it’s just me. My best friends bday is coming up and mashed potatoes are her favorite, but, I was wondering if everything stays the same (time) if I use less than 5lbs of potatoes? Thanks!
