1. How to Cook Sweet Potatoes in Instant Pot (Yield: 4 Servings)
Ingredients
- 4 sweet potatoes
Instructions
Wash the sweet potatoes thoroughly under cool running water, scrubbing the skins to remove any dirt. Since the potatoes cook whole, there’s no need to peel them. Pat them dry with a clean kitchen towel or paper towels.
Pour 1 cup of water into the bottom of a 6-quart or larger Instant Pot.
Place the metal trivet inside the Instant Pot. Arrange the sweet potatoes on top of the trivet in a single layer whenever possible. Keeping the potatoes elevated above the water allows them to steam evenly under pressure.
Lock the lid into place and turn the pressure release valve to the Sealing position.
Select Pressure Cook (Manual) on High Pressure and set the cooking time according to the size of your sweet potatoes:
- Small (under 2 inches thick): 15 minutes
- Medium (2 to 3 inches thick): 30 minutes
- Large (3 to 4 inches thick): 60 minutes
The Instant Pot will take several minutes to come to pressure before the cooking timer begins counting down.
When the cooking time is complete, allow the pressure to release naturally for 10 minutes. After 10 minutes, carefully turn the pressure release valve to Venting to release any remaining pressure.
Open the lid carefully, lifting it away from you to avoid the hot steam.
Use kitchen tongs to carefully transfer the sweet potatoes to a plate or cutting board. They will be very hot.
Check for doneness by inserting a knife or fork into the center of the largest potato. It should slide in easily with little resistance. If the potato is still firm, return it to the Instant Pot and cook on High Pressure for an additional 3 to 5 minutes.
Allow the sweet potatoes to cool for a few minutes before handling. Slice them open, fluff the inside with a fork, and serve as desired.
2. Tips for Perfect Instant Pot Sweet Potatoes
Measure the thickness of the sweet potatoes instead of judging by weight. Thickness has a much greater impact on cooking time than overall weight.
Choose sweet potatoes that are similar in size so they finish cooking at the same time. Mixing very small and very large potatoes often leads to uneven results.
Always place the potatoes on the trivet instead of directly in the water. This allows the potatoes to steam properly and prevents them from becoming waterlogged.
Use a natural pressure release for at least 10 minutes. Releasing the pressure too quickly can cause the centers to finish cooking less evenly.
Test the largest potato first. If the biggest one is tender, the smaller potatoes will almost always be fully cooked as well.
3. Frequently Asked Questions
Do I need to poke holes in sweet potatoes before pressure cooking?
No. Unlike microwaving, there is no need to pierce the sweet potatoes before cooking them in the Instant Pot. The moist pressure-cooking environment allows them to cook safely without vent holes.
Can I stack the sweet potatoes in the Instant Pot?
Yes. If they don’t all fit in a single layer, you can stack them on the trivet. Just try to use potatoes that are close in size so they cook evenly.
Can I cook peeled sweet potatoes in the Instant Pot?
Yes. Peeled sweet potatoes cook much faster than whole ones. If cutting them into large chunks, they generally need about 8 to 10 minutes on High Pressure.
How do I store cooked sweet potatoes?
Let the sweet potatoes cool completely before placing them in an airtight container. Refrigerate for up to 5 days.
Can I freeze cooked sweet potatoes?
Absolutely. Once cooled, wrap each sweet potato individually or store the flesh in freezer-safe containers. Freeze for up to 3 months and thaw overnight in the refrigerator before using.
