What goes in Instant Pot mashed potato

Potatoes: Choose a floury, all-purpose type of potato for fluffy mashed potato. Russet potatoes, Maris piper, Sebago, red potatoes, or Yukon Gold potatoes are all ideal.

Water: you need enough to cover the potatoes, around 3 cups.

Salt to cook the potatoes: This helps to season them while they are cooking and speeds up the cooking process.

Butter and milk (or heavy cream): You need a little of something creamy to offset the starch of the potatoes and stop them from being dry.

Salt to season the potatoes: Season the mashed potatoes to taste once the potatoes and other ingredients are mashed together.

Other flavors you can add to mashed potato

  • Garlic: add one of two cloves of minced garlic, or ¼ teaspoon of garlic powder.
  • Cream cheese or sour cream to add a more tangy flavor. Goes really well with a sprinkling of chives or sliced green onions.
  • Make cheesy mash by adding ½ cup of shredded cheddar. Try adding some bacon bits and ground black pepper for and extra tasty version!

How to make the BEST Instant Pot mashed potato!

It’s a very simple recipe but there are a few specific steps and tips:

  2. Instant Pot mashed potato will keep warm for a while in the Instant Pot. Put the lid back on, but leave it switched off.

How to serve mashed potato

So my favorite way to serve this mashed potato is as a side to just about anything, and completely slathered in this amazing gravy (made from stock).

But, one of the great things about mashed potato as a side dish is that you can get creative by adding new ingredients to make it your own. Here are some fun ideas to try:

  • Top with butter and sprinkle with fresh chives
  • Add ¼ cup of grated Parmesan cheese and stir through
  • Stir through some goat cheese

Serve it alongside your favorite air fryer steak, slow cooker pulled pork, or roast chicken.

Reheating in the microwave for around 2-3 minutes on high until piping hot. Stir it and microwave for an extra minute or two if needed.
