Of all the things I make in my Instant Pot, there’s nothing more convenient (or versatile!) than a batch of sweet potatoes. Topped with a pat of butter and flaky salt, Instant Pot sweet potatoes are a quick side to partner with whatever I’m cooking.

They’re also incredibly versatile. Loaded with beans and greens, they make a wholesome vegetarian dinner. Filled with yogurt or nut butter, and fruit, I have a nutritious breakfast.

Instant Pot sweet potatoes cook up with irresistibly tender, creamy centers, and pressure cooking them takes half as much time as baking them in the oven. Here’s everything you need to know about making them.

3 Tips for Making the Best Instant Pot Sweet Potatoes

1. Start with similarly-sized potatoes. To guarantee that the potatoes are all evenly cooked, it’s essential to start with sweet potatoes that are all about the same size.

2. Add a trivet and water to the Instant Pot. You’ll start by adding one cup of water to the bottom of the Instant Pot, which is what creates the steam (and therefore the pressure) that cooks the potatoes. Just as important is a trivet or steamer basket, which keeps the potatoes elevated above the water.

3. Use potato size to determine cook time. You can cook any and all sizes of sweet potatoes in your Instant Pot. To get the tender, creamy potatoes you crave, plan on a shorter cook time for small spuds and a longer one for the larger ones (more on this below!).

How Long to Pressure Cook Sweet Potatoes

The size of your potatoes is your guide for how long they should cook in the Instant Pot. Regardless of potato size, when the cook time is up, let the pressure naturally release for 10 minutes, then quick release any remaining pressure. 

  • Small sweet potatoes (6 to 8 ounces): 12 minutes under high pressure
  • Medium sweet potatoes (8 to 12 ounces): 18 minutes under high pressure
  • Large sweet potatoes (12 to 16 ounces): 25 minutes under high pressure

  1. Pierce the potatoes with a fork. Wash and scrub 4 similar-sized sweet potatoes, then pierce each one all over with a fork.

  2. Prepare the steamer insert and add water. Set a heatproof trivet or steamer basket in an 6-quart Instant Pot or electric pressure cooker. Add 1 cup water and place the sweet potatoes on the trivet.

  3. Cook under high pressure for 12 to 25 minutes. Lock the lid on and check that the valve is set to seal. Set to cook for 12 minutes under HIGH pressure for small potatoes (6 to 8 ounces each), 18 minutes under HIGH pressure for medium potatoes (8 to 12 ounces each), and 25 minutes under HIGH pressure for large potatoes (12 to 16 ounces each). It will take 7 to 10 minutes to come up to pressure.

  4. Naturally release the pressure. When the cook time is up, let the pressure naturally release for 10 minutes. Quick release any remaining pressure. Open the pressure cooker and remove the sweet potatoes.
