Equipment

Ingredients

  • 2 pounds Yukon gold potatoes Peeled or leave the skin on if you wish. See notes.
  • 3 cups broth Chicken or vegetable. Use enough to completely cover the potatoes. Water can be substituted.
  • 2 tablespoons butter
  • 1/4 cup plain Greek yogurt or sour cream
  • 1/2 cup buttermilk
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • salt and pepper to taste

Instructions

Instructions

  • Cut the potatoes into chunks about an inch thick.

Stovetop Boil

  • Add the potatoes to a large pot along with cold water or broth. Use enough to completely cover 1 inch above the potatoes.
  • Place the pot on the stove on high and allow the liquid to come to a boil. When the liquid reaches boiling, reduce to medium-high. Cook the potatoes for 10-15 minutes until the potatoes are tender. Pierce with a fork to check.
  • Drain the excess liquid from the pot.

Instant Pot Potatoes

  • Place the potatoes in the Instant Pot with enough broth or water to completely cover the potatoes. (No need to go an inch above).
  • Cook on Manual High Pressure for 10 minutes.
  • When the Instant Pot beeps that it is complete, quick release the steam.
  • Open the lid and drain the excess liquid from the pot.

Assembling the Mashed Potatoes

  • Mash the potatoes with a potato masher.
  • Add in the buttermilk, Greek yogurt or sour cream, butter, and spices.
  • Stir until creamy.

Notes

You can use whatever type of potatoes you wish.
Other spices I love to add from time to time are smoked paprika, Cajun Seasoning, or Creole seasoning for extra flavor and a twist.
When you boil the potatoes for too long it will result in potatoes that are overcooked and absorb a lot of liquid. When you go to mash them, they will be soupy. Instead of having fluffy mashed potatoes, you will have a watery blob. If you are cooking your potatoes on the stovetop, keep a watchful eye.
You can use milk, heavy cream, or half and half instead of buttermilk if you wish.
