One: Peel and dice the sweet potatoes into 1-inch thick cubes. Season with cinnamon and thyme, and stir to coat the potato chunks evenly.
Two: Add a cup of water to the bottom of the Instant Pot, insert a trivet or steamer basket, and then add the sweet potatoes. The potato cubes won't be completely covered with water, but this is fine. Seal the lid, and select the PRESSURE COOK or MANUAL setting. Cook the potatoes on HIGH pressure for 10 minutes. When the timer is up, manually release the pressure by carefully performing a quick release.
Three: Drain the potatoes to remove any excess water. Use a potato masher to mash the potatoes, and add butter. At this point you can add any other ingredients that you like such as extra seasoning or milk to taste. See the Variations section below for more ideas.
- Dice the potatoes into similar sizes to allow them to cook evenly.
- You can omit the seasoning, or replace it with your favorites.
- Adding milk to the mash can make it more fluffy. Using butter makes it more creamy. You can choose whichever one you prefer.
- Be careful when you release the pressure, as the steam will be very hot. I like to turn or push the venting valve with a wooden spoon to keep a safe distance.
Instant Pot sweet potato mash is best served as a side dish. It's incredibly versatile, and you can pair it with any entree that you like.
You can also use this mash in place of mashed potatoes in dishes like pies and casseroles. For example, try it in Sausage and Mash Pie.
With milk: Replace the butter with milk, or add extra milk to taste. This will make the mashed potatoes a fluffy texture. Use any milk that you like, for example skim milk or oat milk.
Without butter: Omit the butter, or replace it with milk or olive oil. The butter makes the mash rich, dense and smooth. Leaving it out will make the mashed sweet potatoes lighter.
