It’s insanely hot in these parts right now, but I’m choosing to ignore it.  It is fall after all — I have pumpkin baking and comfort food on my mind!

I can’t let silly things like weather stand in my way, especially during my favorite season. 

Speaking of comfort food, mashed potatoes are my family’s all time favorite side dish.  That’s probably why I have so many recipes for them! My yukon gold mashed potatoes have been a tried and true favorite for years, and my slow cooker mashed potatoes have tangy buttermilk flavor and are a more hands off way to prepare them.

I decided to give our favorite side dish a colorful autumn upgrade with these Instant Pot Mashed Sweet Potatoes!  

I’m all about the orange food right now. 🙂

How to make this recipe

Instant Pot mashed sweet potatoes are extremely easy to make, and they come out perfectly creamy and velvety every single time.

  • Peel the sweet potatoes and cut into 2″ chunks.
  • Place the sweet potatoes into the Instant Pot along with 1 teaspoon of salt.  Add 1 cup of water and secure the lid.
  • Press the Pressure Cook button and set to cook at High Pressure for 8 minutes.
  • It will take the Instant Pot about 15 minutes to come to pressure, then cook the potatoes for 8 minutes.  When they’re finished cooking, quick release the pressure and remove the lid when it’s safe to do so.
  • Drain the sweet potatoes well in a colander, then add back to the Instant Pot. Add the half and half and butter, and mash well with a potato masher.
  • Stir in the orange zest, rosemary, and season with salt and pepper to taste.   Serve warm and enjoy!

Recipe notes

  • Be sure to drain the sweet potatoes very well to avoid watery sweet potato mash!
  • Substitute the half and half with whole milk, heavy cream, buttermilk, skim milk, or any combination of them!  Make these mashed sweet potatoes dairy free by using coconut milk or your favorite non-dairy milk and omit the butter.
  • Customize these mashed sweet potatoes to your liking!  Sub the rosemary with your favorite chopped herbs, or add roasted garlic for extra savory mashed sweet potatoes.  Add maple syrup and cinnamon, and top with pecans for a healthier sweet potato casserole inspired side.
  • Make these mashed sweet potatoes ahead and select the Keep Warm button on the Instant Pot.  Secure the lid and stir from time to time until ready to serve.
