Add potatoes to the instant pot, and add enough water to just cover the potatoes. Close the lid onto the instant pot, and seal the pressure valve. On manual setting, set on high for 8 minutes. Once the time is up, use an oven mitt to quick release the pressure valve. (Water will come out the valve, so use an oven mitt or towel to protect your hand!).
Once the pressure is released, open the lid and drain the potatoes. Return them back to the pot and add butter, spices, and half & half. Use a hand mixer to mash the potatoes. Sprinkle some extra parsley on top and serve.
