Instant Pot Sweet Potatoes (Fool-Proof Formula!)

If you love hands-off cooking, you’ll love these Instant Pot Sweet Potatoes. I love how they get perfectly tender, without turning on your oven or heating up your kitchen!

Instant Pot Sweet Potatoes

Why cook food in a pressure cooker?

There are several reasons to cook food in a pressure cooker, rather than using the stove or oven. The first being that it makes the process totally hands-off. Just add the sweet potatoes (and water to the bottom of the pot), seal the lid, press a button, and walk away until they’re done. There’s no risk of the potatoes burning like they might in the oven.

Pressure cooking has also been shown to preserve more nutrition in food when compared to other methods of cooking. (source) This is possibly due to the fact that the pressure cooker cooks foods at a lower temperature than most other cooking methods (usually at or below 250ºF), while also being faster in many cases.

How Long to Cook Instant Pot Sweet Potatoes

Looking at the general Instant Pot time charts online, I found the proper times for cooking whole sweet potatoes to be a bit vague. A “small” or “medium” potato isn’t super-descriptive as far as weight goes, so I took to my kitchen to experiment with my Instant Pot, kitchen scale, and several sizes of potatoes.

If you’re the type who likes general guidelines, here’s what I go by:

  • Small sweet potato (8 ounces or less): 20 minutes
  • Medium sweet potato (9-14 ounces): 30 – 35 minutes
  • Large sweet potato (15 ounces and up): 40 – 50 minutes

All of these timings above are using the manual high pressure setting, and allow for 10 minutes of natural pressure release before opening the lid. So, be sure to add about 8 minutes for the pot to pressurize, and 10 minutes for the pot to de-pressurize to your overall expected time. This means a small sweet potato will take 38 minutes total, from start to finish.

A Fool-Proof Formula for Instant Pot Sweet Potatoes

Again, the timings above are very general, so your potatoes might need another minute or two if you open the lid and find they are still a bit firm in the center. If you prefer to have an exact timing formula, I’ve found that you can multiply the weight of the potato (in ounces) by 2.5 minutes to get a more exact time.

  • ( __ ) ounces  x  2.5 minutes = cooking time at high pressure

For example, an 9 ounce potato x 2.5 minutes = 22.5 minutes of cook time at high pressure. (Plus the 10 minute natural release later.) And a 16 ounce potato x 2.5 minutes = 40 minutes of cook time at high pressure.

Note: If you’re cooking multiple sweet potatoes that vary in size, always go by the cooking time for the largest potato to ensure they are fully cooked. (It’s not a big deal if you over-cook the smaller potatoes.) If the potatoes are drastically different, you can cut the extra-large potatoes in half to shorten their cooking time.

Instant Pot Sweet Potato Cubes

If you’d rather not cook whole sweet potatoes, you can cut the sweet potatoes into cubes for much faster cooking. I put the sweet potato cubes into a steamer basket with water below, then cook them for 8 minutes at high pressure with a quick release. (Meaning, you move the steam release valve to venting as soon as the Instant Pot beeps to signal that the cooking cycle is complete.)

The cubed sweet potatoes can be easily mashed for Mashed Sweet Potatoes, added to my Sweet Potato & Quinoa Mason Jar Salads, or can be saved and used later in a Sweet Potato Smoothie.

What Goes Well with Sweet Potatoes?

If you’re wondering what to serve your sweet potatoes with, I thought I’d share some of my favorite pairings. For food combining purposes, I like to serve baked sweet potatoes with a vegan salad or soup for a filling, yet easy-to-digest meal.

Here are some of my favorites:

However you serve these Instant Pot Sweet Potatoes, I hope you’ll love them! If you have leftover sweet potato, keep in mind that they freeze well, too. You can save the frozen sweet potato to add to smoothies or curry sauces in the future. sweet potato being mashed with a fork

Here's how to cook perfect INSTANT POT SWEET POTATOES. With this fool-proof formula, you can determine the perfect pressure cooking time based on the weight of your sweet potatoes.

Ingredients
  • 2 (8 ounce) sweet potatoes
Instructions
  1. Fill your Instant Pot with 1 cup of water and place the trivet that comes with your machine on the bottom, to keep the sweet potatoes above the water.

  2. Poke the sweet potatoes several times with a fork to vent, then place them on top of the trivet. Secure the lid, moving the steam release valve to Sealing. Press the Manual or Pressure Cook button and cook at high pressure for 20 minutes. (This time will vary based on the weight of your potato; see the Notes below for the formula to use.)

  3. When the cooking cycle is complete, allow the pressure to naturally release for 10 minutes. This means you don't do anything until the screen reads LO:10. When 10 minutes has passed, move the steam release valve to venting to release any remaining pressure. (It's okay if the sweet potatoes rest in the pot for longer than 10 minutes, though-- they can't burn in there.)

  4. When the floating valve in the lid drops, it's safe to remove the lid. Use oven mitts to remove the hot sweet potatoes from the pot. You can let them rest until cool enough to handle, or slice them in half immediately and serve piping hot.

  5. Leftover cooked sweet potatoes can be stored in an airtight container in the fridge for up to 5 days, or frozen for up to 3 months for future use.

Recipe Notes

How to Calculate the Cook Time:

If you know the exact weight of your sweet potatoes, you can use that to calculate the proper cook time. Multiply the weight of your potato (in ounces) by 2.5 to get the minutes you'll need to cook at high pressure. For example, an 8 ounce potato x 2.5 = 19.2 minutes. I round up to 20 minutes, since the Instant Pot only cooks in whole numbers. Always allow 10 minutes of natural release for the potato to finish cooking, before removing the lid.

Recipe Notes:

  • This timing is for sweet potatoes only. White potatoes cook faster and won’t go by this timing formula.
  • To speed the cooking time, cut the sweet potatoes in half and go by the appropriate timing for the weight of the largest half. You can also cut the sweet potatoes into cubes for even faster cooking, as noted in the post above.

Thanks for the tips!

Thank you for figuring this out! I haven’t had the best luck with cooking sweet potatoes up until now, but I just followed your formula and they came out perfectly. Will definitely be using this from now on!

heather

I love making sweet potatoes in the Instant Pot! This timing worked great for me today.

Penny

You are a genius. Tried this formula yesterday and it was the first time that ALL of my sweet potatoes were cooked all the way through!

Hannah

I love the details you include in your recipe directions. I’m still new to the Instant Pot, and this is really helpful! I’ve been watching your YouTube videos, too, and you’re making me feel more comfortable with it all. Thanks!

JD

The formula works! I used it for dinner last night with halved sweet potatoes and timed it for the largest one of the batch. No issues whatsoever and, thanks to your info on timing of pressurization and pressure release, the potatoes were ready with a few minutes to spare. Thanks for doing all the legwork on figuring this one out!
