Instant pot cubed sweet potatoes are a simple and easy way to prepare this versatile vegetable. In under 20 minutes, you will have perfectly steamed sweet potatoes. Enjoy them as a side dish, make a mash, or even add them to your muffin batter.
Whether you are looking for an easy side dish or need sweet potatoes for a holiday casserole, these instant pot sweet potatoes are ready much faster than they do when cooked on the stove. They come out very tender, creamy, and full of flavor every time.
They are similar to our air-fried sweet potato cubes, only the instant pot version is made with no oil or spices so that the potatoes can be customized and used in a variety of ways.
Check out our other 4 methods you can cook sweet potatoes.
The recipe requires only 2 ingredients. But you can use different seasonings and flavors to dress up already-cooked sweet potatoes.
- Sweet Potatoes: I used jewel sweet potatoes. Any orange flesh sweet potatoes are great for steaming. You can also use a white Hannah sweet potato. It is a dryer type but still turns out tender and creamy.
- Water: filtered or tap water for steaming.
How to cube sweet potatoes
First, wash and peel sweet potatoes. If you decide to keep the skin on, scrub them well with a brush.
Usually, I peel my sweet potatoes for this recipe.
If you decide to roast them in olive oil after steaming, it's better to keep the skin on for some extra texture and crispiness.
Now, cube them into even pieces. Since the potato is round, some pieces will look like cubes and some like chunks. I try to keep them the same size, around 1 ½ x 1 ½x1 ½ inch cubes.
You can make them smaller or bigger, it's up to you. I do not recommend making them smaller than 1 inch as they might turn out mushy.
How to steam sweet potato cubes in the instant pot
After you wash and cut the potatoes into cubes, they are ready to go into the instant pot.
This recipe is perfect if you need to steam potatoes without an actual steamer. We are going to use only the instant pot and the trivet.
Trivet works perfectly fine. The goal is to keep the potatoes above the water, so they steam and do not boil. Boiling will make them too soggy and watery.
If you use the trivet, the cubes must be at least 1 ½ inches or more, so they do not fall into the water.
Step 1. First, place the trivet in your instant pot and pour one cup of water. It does not matter how many cups of cubes of potatoes you are steaming, always add only one cup of liquid.
Step 2. Carefully (so they do not fall in a water), pile up sweet potato cubes on top of the trivet. Start with the biggest chunks.
Step 3. Close the lid and turn the steam valve in the locking position. Set your instant pot. Press the Manual or Pressure Cook button and set the time to 5 minutes on high pressure. It will take between 8-10 minutes until it builds up pressure. After it does, the timer will start the countdown.
Step 4. After the timer beeps 3 times, the potatoes are cooked. Open the pressure valve to do a quick pressure release. Open the lid and serve the potatoes.
Depending on the size of the cubes, you may need to adjust the cooking time. I recommend different times depending on how you like them - extra tender (great for mashing) or firmer cubes (keep in shape, great as a side dish). See my recommendations below:
2 ½-3 inches cubes (Large) - 6 minutes for extra tender, 5 minutes for firmer cubes.
1 ½ - 2 inches cubes (Medium) - 5 minutes for extra tender, 4 minutes for firmer cubes.
1-inch cubes (Small) - 4 minutes for extra tender, 3 minutes for firmer cubes.
Instant Pot - I used the Instant Pot duo.
Steamer or Trivet - if you do not have a steamer, use the rack (trivet) that came with your Instant pot. It is also perfect for making steamed whole white potatoes.
- keep the potatoes above the water level by using a trivet or a steamer.
- scrub the potatoes well if not peeling.
- always do a quick release after the cooking time elapsed.
- cooking time will be different depending on the size of the cubes (see cooking times recommendations above), but not on the number of potato cubes.
- refrigerate the leftovers in an air-tight container for up to 3 days.
- you can freeze cooked mashed sweet potatoes up to 3 months.
What to serve sweet potato cubes with
And of course, it can be a great Thanksgiving side dish to go with a whole roasted turkey or something as simple as air fryer turkey thighs.
