Instant Pot Sweet Potato Mash

Mashed Sweet Potatoes Instant Pot

Are you team sweet potatoes or team white potatoes? In the Milner kitchen we are 2 in favour of sweet, to 3 in favour of white potatoes, with our Boxer happy to lick the plates of either!

Its my little boy Jorge (he is about to turn 7) and myself that are obsessed with sweet potatoes and if both are in front of us, we would both choose sweet potatoes. In fact, put normal white potatoes in front of Jorge and he will play with them for a while and not really eat them.

Whilst we were on holiday in Crete they made the best sweet potato puree at the Italian buffet, and it reminded me that when sweet potatoes are back in season, that we must make some instant pot sweet potato mash!

Can You Make Instant Pot Sweet Potato Mash?

Yes, you can. Sweet potato mash in the instant pot works in a similar way as it does in a pan, just its much quicker.

You can either boil your sweet potatoes in the instant pot like you would in a pan or steam them to retain the flavour and nutrients of the sweet potatoes.

You can also use the instant pot to mash the sweet potatoes once the instant pot has beeped, just make sure you use a silicone that wont scratch your instant pot if you do this.

Boiling Sweet Potatoes In Instant Pot

If you wish to boil sweet potatoes in instant pot, like you would on a stovetop in a pan, then you can do that and of course the biggest benefit is that you can mash the sweet potatoes in the instant pot, serve them from the instant pot, or even transport them from the instant pot, for a family gathering you’re at. Just think of Thanksgiving.

To boil sweet potatoes in the instant pot, is exactly how we are showing you to make sweet potato mash in the instant pot today, and works very similar to the pan, its just going to pressure is added to the steps.

Can You Make Steamed Sweet Potatoes?

Yes, you can also use the instant pot to steam sweet potatoes, and they are just as delicious, even not better.

But this only works if you are doing a smaller portion, because a catering size of sweet potatoes for Thanksgiving just doesn’t have the space.

That is because to do steamed sweet potatoes in the instant pot, you have a small quantity of water in the bottom of the instant pot to bring it to pressure, then the sweet potatoes sit in a steamer basket above, meaning the portion size/space is much smaller. 

Can I Make Mashed Sweet Potatoes Ahead Of Time?

Yes, you sure can make mashed sweet potatoes ahead of time and I highly recommend doing so.

You can then reheat sweet mashed potatoes just before serving in the microwave, or use the slow cooker setting of the instant pot, to keep them warm before you are serving them.

How Do You Fix Watery Mashed Sweet Potatoes?

The easiest way to fix watery mashed sweet potatoes, is to give them an extra draining. Place the mashed sweet potatoes into a sieve and place the sieve over a large bowl. Then let the water drip out of them into the bowl below. This will get rid of a lot of the liquid, then you can give it a mix and you have perfect creamy sweet potatoes again.

Should You Peel Sweet Potatoes Before Boiling?

Yes, we recommend peeling your sweet potatoes before boiling. Its so much easier than trying to peel them once they have been boiled, and doesn’t take long at all.

Mashed Sweet Potatoes Instant Pot Ingredients

Mashed Sweet Potatoes Instant Pot Ingredients

Sweet Potatoes – We recommend a big batch of sweet potatoes, because once you mash them the portion really does reduce. We also recommend making instant pot mashed sweet potatoes with large sweet potatoes, as the small out of season ones would require a lot of peeling to make a batch with.

Butter – We all know that everything tastes better with butter and pressure cooker sweet potatoes makes an excellent pairing. We recommend salted butter though for flavour.

Stock – You can add water to the instant pot, but sweet potato mash is much more flavoursome if you add some veggie stock. We made instant pot veggie stock from peelings then freeze for later and then add to the instant pot with the sweet potatoes.

Seasonings – Then we finished off with some delicious seasonings such as salt, pepper, bouquet garni, (can sub for any mixed herbs/Italian seasonings).

Can You Recommend An Instant Pot?

I often get asked which electric pressure cookers we recommend and which one we use. In 95% of our instant pot recipes, we use either this instant pot duo (we have both the 6qt and 8qt) or the Ninja Foodi air fryer and pressure cooker in 1. You can click on the links above and read up on them.

Plus, we recommend you head over to our instant pot recipes category as we have many electric pressure cooker recipes and have been using instant pots for 5 years.

How To Cook Sweet Potato Mash In Instant Pot?

instant-pot-sweet-potato-mash-step-by-step
  • Load. Pour 2.5 cups (600ml) of veggie stock into your instant pot inner pot. Then peel your sweet potatoes and add them to the liquid. Give it a quick stir.
  • Season. Next add chunks of butter over the sweet potatoes so that it will melt into the sweet potato as it cooks. Plus, season generously with salt, pepper, and bouquet garni.
  • Cook. Then place the lid on your instant pot, set the valve to sealing and pressure cook sweet potatoes for 10 minutes followed by a quick pressure release (QPR).
  • Drain. When the instant pot is done, give the sweet potatoes a good draining of excess liquid with a sieve as it stops your sweet potatoes from being overly watery.
  • Mash. Next using a bowl or your instant pot inner pot, mash with some extra butter and if needed extra salt and pepper, until you have creamy mashed potatoes.

You now have creamy instant pot mashed sweet potatoes.

How Long To Cook Sweet Potatoes In Instant Pot?

The sweet potato instant pot time is JUST 10 minutes. This is fantastic for fast mashed sweet potatoes.

Of course, if we were just making cubed sweet potatoes, we wouldn’t need to do them as long, but mashed potatoes are easier when the potatoes are very soft.

Sweet Potato Puree Instant Pot

If you would like to make sweet potato puree, then I recommend following the same instant pot cook time and then once done, make sure you drain the sweet potatoes for longer and then instead of adding extra butter, to add cream instead and then you have perfect sweet potato puree.
