  • 5 pounds russet potatoes peeled and cut into chunks
  • 1 1/2 cups water
  • 1 teaspoon salt
  • 1 teaspoon black ground pepper
  • 1/2 cup cream or milk
  • 1/4 cup unsalted butter
  • 1 teaspoon garlic powder optional
  • Salt and Pepper to taste
  • Optional:
  • 1/2 cup Ranch salad dressing / or sour cream / or cream cheese


  • Add water to the pot, make sure you use at least the minimum amount required for your pot size.
  • Place peeled and chopped potatoes in the Instant Pot and season with a bit of salt and some pepper.
  • Put the lid on, close it and set the valve to “Sealing” position.
  • Press the Manual button and using the +/- buttons set the cooking time to 12 minutes.
  • It may take a while for the pot to come to pressure, because of the high volume of potatoes. That is ok, make sure the valve is sealed.
  • Once the Instant Pot is done cooking and it beeps, do a Quick Pressure Release by turning the valve to Venting position.
  • Once the pressure has vented, open the lid, carefully remove the pot and drain the water, save about 1 cup.
  • Add back the pot to the cooker, and while the potatoes are still hot, add the butter and stir.
  • Heat the cream or milk in the microwave for 30 seconds and add it to the pot as well.
  • Use a potato masher to mash the potatoes right into the pot, add salt and pepper to taste. Add garlic powder if you are using it.
  • To make the potatoes fluffier, you can use a hand mixer to fluff them up.
  • If you want the potatoes thinner in texture, you can add a little of the reserved water or more milk or cream.
  • At this point, stir in the Ranch salad dressing if you want to make Ranch mashed potatoes.
  • Enjoy!
