Use the Right Potatoes

I recommend using Russet Potatoes for this or any mashed potato recipe.

Russet potatoes are the classic rugged brown-skinned potatoes that become fluffy and creamy when cooked and mashed.

It’s best to peel these potatoes before cooking for mashed potatoes.

For baked potatoes, leave the heavy skin on; it’s edible and nutritious. Of course, they should be scrubbed clean before cooking.

Ingredients

SHOT OF 4 RUSSET POTATOES WITH INGREDIENTS TO MAKE MASHED POTATOES LISTED ON ONE OF THEM
  • Russet Potatoes
  • Butter
  • Whipped Cream Cheese – Substitute sour cream if desired
  • Salt and Pepper
  • Water
  • Fresh Chopped Parsley for Garnish if desired

Let’s Make Instant Pot Mashed Potatoes

  1. Wash, peel, and slice potatoes.
  2. Place the potato slices into the bottom of the instant pot bowl.
  3. Add enough water to cover the potatoes.
  4. Add 1 teaspoon of salt.
  5. Place the lid on the instant pot to seal it closed.
  6. Cook on manual high pressure for 8 minutes.
  7. When the timer goes off, let the pressure release naturally, on its own, for 3 minutes.
  8. Drain the potatoes and return them to the instant pot.
  9. Add the remaining salt, pepper, whipped cream cheese, and butter.
  10. Mash until smooth. If the potatoes are too stiff, add 1/4 – 1/3 cup of warm milk (20-30 seconds in the microwave).

Krazy Kitchen Mom Tips for Making the Best Mashed Potatoes

  • Don’t cut the potatoes too small. Tiny sliced potatoes absorb too much water and make the potatoes mushy and gummy.
  • Start with cold water in the instant pot bowl
  • Potatoes need a lot of salt; be sure to add it before and after cooking.
  • If adding milk to potatoes, do not use cold milk. Heat it in the microwave for 20-30 seconds.
  • Do not over-mash the potatoes. Overworking the potatoes will cause them to be gummy.
  • I use a hand-held potato masher for mashing. But if you have a potato ricer, use it because it makes the smoothest potatoes.
