Place the steel steamer rack inside the instant pot, and add one cup of water.

Rinse the sweet potatoes* and arrange them on top of the rack in a single layer, as many as you would like, and can fit.

Lock the lid and set the manual pressure: 15 minutes for small-medium sweet potatoes, and 19 minutes for large sweet potatoes.

At the end of cooking, let the pressure release naturally for at least 10 minutes, or until the button drops.
