The easiest way to cook sweet potatoes is definitely in your Instant Pot! (Recipe is for a 6qt Instant Pot Duo)
Ingredients
3-4medium sweet potatoessee Notes for size recommendations
1cupwater
Instructions
Add 1 cup water to the bottom of your 6qt Instant Pot Duo.
Place trivet inside.
Wash potatoes thoroughly and place inside.
Close lid.
Ensure Instant Pot is set to Seal.
Cook on High Pressure and manually set for 18-23 minutes (18 minutes for potatoes closer to 6 inches in circumference and 23 minutes for potatoes closer to 8 inches in circumference).
Allow Instant Pot to naturally release for 10 minutes and then manually release remaining pressure according to manufacturer's instructions.
Notes
I am defining a medium sweet potato as being approximately 6-8 inches in circumference.
If you are potatoes thicker than 8 inches in circumference you will need to increase cooking time OR you can simply cut them in half and then I would recommend cooking for 18 minutes.
I don't recommend using huge sweet potatoes. It might result in an over-done outside layer and a not-done center. The sweet potatoes I used were approximately 8-10 ounces or 6-8 inches around. If you are using very large sweet potatoes I would recommend cutting them in half and then reducing the cook time by several minutes.
