Use a fork to poke holes in the sweet potatoes; holes should be approximately 1 inch apart around entire potato.
Add 1 cup of water to your Instant Pot and set the metal trivet over top. Then place sweet potatoes on the trivet (they can be touching, but to ensure even cooking, don't stack or overcrowd).
Secure lid and pressure cook on high for 20-25 minutes (20 minutes for small sweet potatoes (~2 inches in diameter) and 25 minutes for medium (~2.5-3 inches in diameter)).
Once the timer goes off, allow to naturally release for 10 minutes, then release any remaining pressure. Carefully remove lid once steam has fully escaped.
Enjoy immediately with your favorite toppings, as a side, orfor adding to muffins, smoothies, and more. Best when fresh. Store cooled leftovers in the refrigerator up to 3-4 days. Enjoy cold, reheat in the oven, or slice and cook on the stovetop in a large skillet.
