Instant Pot Mashed Sweet Potatoes
See my guide on how to use an Instant Pot.
These Instant Pot Mashed Sweet Potatoes are so creamy and easy to make! They are the perfect side dish for the holidays or a weeknight dinner.
Sweet potatoes are one of my favorite vegetables. They are a delicious, versatile ingredient that you can enjoy in both sweet and savory dishes. From simple baked sweet potato to crispy baked sweet potato fries and sweet potato casserole, there are so many tasty ways to prepare sweet potatoes.
I’ve already shared my Instant Pot Sweet Potatoes recipe, which is how I cook whole baked sweet potatoes in the pressure cooker. My Instant Pot Mashed Potatoes are proof that pressure cooker mashed potatoes are the best ever, with a fluffy, creamy texture that can’t be beat. So I was pretty excited to try making mashed sweet potatoes in the Instant Pot. And now that I have, I’m hooked!
These Instant Pot Mashed Sweet Potatoes are lightly sweetened and flavored simply with butter, salt and pepper. Below I’m sharing ideas for variations on this recipe, as well as my tips for how to get the smoothest, creamiest mashed sweet potatoes.
How to Make Instant Pot Mashed Sweet Potatoes
This recipe has just a few simple steps:
- Peel and cut the sweet potatoes.
- Pressure cook the sweet potatoes.
- Mash and then stir in butter, pure maple syrup, salt, pepper and milk.
When you cut the sweet potatoes, chop them into large 2-inch pieces. Depending on the size of your sweet potatoes, you may need to cut each potato into halves, thirds, fourths or sixths. The 15 minutes of pressure cooking will cook 2-inch chunks of sweet potatoes to tender.
You’ll cook the sweet potatoes in a steamer basket in your Instant Pot. If you don’t have a steamer basket, you can set the potato pieces on the metal trivet that comes with most Instant Pot models. Be sure to add 1 1/2 cups of water to the bottom of the pot before you put the sweet potatoes in. The water is needed for the pot to pressurize.
When the cook time ends, quick release the pressure. Then carefully open the Instant Pot lid by turning the steam release valve to the venting position. Transfer the sweet potatoes to a plate or bowl so that you can rinse out the Instant Pot inner pot. Dry the pot and then return it to the Instant Pot base. Put the cooked sweet potatoes back in the pot to mash.
The Best Way to Mash Sweet Potatoes
I’ve tested out different ways to mash sweet potatoes. You can mash them by hand using a potato masher. You can also mash them with a hand mixer, right in the Instant Pot. If you don’t mind dirtying another bowl, you can use a stand mixer to mash the potatoes.
But if you want your mashed sweet potatoes to be really smooth and creamy, you should use an immersion blender:
- First, mash the sweet potatoes with a potato masher or hand mixer. You can do this right in the Instant Pot.
- Stir in the butter, seasonings and milk.
- Use an immersion blender to mash the sweet potatoes a second time, until they are extra smooth and creamy. You can do this right in the Instant Pot.
Once you’ve mashed your sweet potatoes, you can stir in more milk as needed to reach your desired texture. I find that the amount of milk needed depends on the sweet potatoes – some are more “thirsty” and will absorb more milk than others. Sometimes 1/4 cup of milk is enough, and sometimes you need to add a few extra tablespoons of milk.
You can leave your sweet potatoes in the Instant Pot on the keep warm setting for up to 1 to 2 hours while serving your meal. If they start to dry out, stir in more warmed milk.
Instant Pot Mashed Sweet Potatoes Recipe Variations
- Try adding cinnamon, nutmeg, and/or vanilla extract to this recipe for sweeter, spiced mashed sweet potatoes. Start with 1/2 teaspoon of vanilla, 1/2 teaspoon of ground cinnamon and just a pinch of nutmeg and then adjust to your tastes.
- Top your mashed sweet potatoes with toasted nuts. Try pecans, walnuts or sliced almonds.
- Make savory mashed sweet potatoes. Instead of pure maple syrup, flavor the sweet potatoes with butter and herbs, to taste. Fresh herbs are best, and I recommend starting with 2 to 3 teaspoons of chopped fresh herbs total. Try thyme, rosemary, sage, or a combination of these.

Instant Pot Mashed Sweet Potatoes
- 3 ½ pounds sweet potatoes
- 1 ½ cups water
- 2 tablespoons unsalted butter, cut into 4 pieces
- 1 tablespoon pure maple syrup, or honey or brown sugar
- ½ teaspoon salt, or to taste
- black pepper, to taste
- ¼ cup warm milk, plus more as needed, whole or 2% is best
- Peel the sweet potatoes and cut them into large (2-inch) pieces. Add the 1 ½ cups water to the bottom of the Instant Pot inner pot. Place a steamer basket in the pot. Put the sweet potatoes in the steamer basket. (If you do not have a steamer basket you can set the sweet potatoes on top of the metal trivet that comes with most Instant Pot models.)
- Close the Instant Pot lid and turn the steam release valve to the sealing position. Set the cook time to 15 minutes at high pressure using the Pressure Cook or Manual function.
- The Instant Pot will take about 15 minutes to reach pressure and then the cook time will begin counting down. When the cook time ends, quick release the pressure by carefully turning the steam release valve to the venting position (I do this with the handle of a long spoon). Once all of the steam has escaped and the pin drops down, carefully open the Instant Pot lid.
- Use a spoon to transfer the potatoes to a bowl. Wash and dry the Instant Pot.
- Add sweet potatoes back to the empty Instant Pot. Mash the sweet potatoes using a potato masher, hand mixer or immersion blender. Then stir in the butter, maple syrup, salt and pepper. Finally, stir in the warm milk, adding more milk as needed to reach your desired texture. For the creamiest, smoothest mashed sweet potatoes, I like to first mash them with a potato masher or hand mixer. Then, after mixing in the other ingredients, I use an immersion blender to get them really smooth and creamy.
- Taste and adjust the seasonings as needed. Serve.
- Recipe can be doubled to serve more people. Double all of the ingredients (except for the water) but keep the cook time the same. A double recipe will fit in an 8 quart pot, but if you have a 6 quart pot you may need to limit the amount to 1.5 times the recipe.
I would like to try the steam setting to cook this recipe. Would I use the same 15 minute cooking time?
The steam setting cooks at low pressure vs. high pressure so you would need to increase the cook time. I have not tested this recipe using low pressure so I can’t advise on exactly how long the sweet potatoes would need to cook on the steam setting. I recommend following the recipe as written for best results. 🙂
