For perfectly consistently cooked Sweet Potatoes, I like to slice my them up before cooking.
(you can totally throw them in whole after poking some holes in them if you want, just add 3-5 minutes cook time depending on size)
pour 1 cup of water into the insert of your Instant Pot. Then put the trivet in.
Now either place sweet potatoes right on top of the trivet OR use a steam basket (makes it easier to take out)
place lid and check that lever is switched to seal. press Pressure Cook (or Manual) and adjust the time to 8 minutes.
Naturally Release Pressure for 5 minutes or more. Then Release remainder of pressure.
remove from the Instant Pot
Season to your liking and enjoy!
~ My favorite is simply, butter, pink salt, and a little mozzarella cheese.
