Instant Pot Sweet Potatoes, Cubed

The most important thing to know about steamed Instant Pot sweet potato cubes is that the size of the cubes (or chunks) determines the cooking time.

For 1x1x1 inch cubes or 1/2-inch thick rounds, 5 minutes will give you a soft texture that is easily pierced with a fork but the pieces still hold their shape. 

If you want a firmer texture, try 3 minutes. If you want a very soft texture, try 8 minutes.

Remember, it's best to error on the side of undercooking the sweet potatoes, because you can always secure the lid again and cook the potatoes for a few more minutes. 


Units Scale
  • 4 to 8 sweet potatoes (about 2 to 4 pounds), cut into 1-inch cubes* (peeled or unpeeled)
  • 1 cup water

*Slightly smaller or larger cubes are okay, such as ¾-inch cubes or 1 ½-inch cubes. You don’t have to cut precise cubes. The most important thing is that all of the chunks are about the same size. See the blog post above for links to videos that show how to cut sweet potato cubes. 



  1. Add the water to the Instant Pot insert.
  2. Place a steamer basket over the water.
  3. Secure the lid.
  4. Press Manual to program the Instant Pot to cook for 5 minutes on high pressure.
  5. Quick release the pressure by manually moving the steam release valve to Venting (use caution -  hot steam!)


This recipe was tested in a 6-quart Instant Pot. 

Instead of cubes or chunks, you can also cook rounds of sweet potato that are 1/2-inch thick using this cooking time and method. 

If the sweet potato is not as soft as you'd like, then either set the lid back on the pot and let the potatoes steam longer in the residual heat or secure the lid and cook the potatoes for 1 to 3 more minutes. 

These potatoes are soft enough to mash with a fork, but if you want really soft sweet potato cubes then increase the cooking time to 8 minutes. 

Using a steamer basket yields the best results because it keeps the potatoes from getting waterlogged and soggy.
