How to Make Instant Pot Mashed Sweet Potatoes Recipe
Step 1: Prepare and Place Ingredients in the Instant Pot
Start by peeling and cubing your sweet potatoes into uniform 1-inch pieces; this helps them cook evenly. Then place the sweet potatoes, 1 cup of water, and ½ teaspoon kosher salt into your Instant Pot. This combination sets the stage for perfectly steamed potatoes with just the right amount of seasoning.
Step 2: Pressure Cook the Sweet Potatoes
Secure the lid on your Instant Pot, making sure the valve is set to the “sealing” position. Select the Pressure Cook or Manual function and set the timer for 12 minutes. This quick cook time harnesses the power of steam to soften the potatoes quickly while locking in their natural sweetness.
Step 3: Carefully Release the Pressure
Once the cooking cycle ends, carefully switch the valve to the “venting” position to manually release the pressure. Be cautious as steam and any splatter could escape rapidly. This step gets your Instant Pot ready to safely open and proceed to the next stage.
Step 4: Drain and Return to Pot
Drain any leftover water from the cooked sweet potatoes and transfer them back into the Instant Pot’s inner pot. This helps keep them warm and ready for combining with creamy ingredients.
Step 5: Add Half and Half and Butter
Add ¼ cup half and half and 4 tablespoons of unsalted butter directly to the potatoes. These ingredients are the magic behind the luxurious, rich texture of the mash.
Step 6: Mash or Blend to Desired Consistency
Using a potato masher or immersion blender, process the sweet potatoes until smooth or slightly chunky—depending on what you prefer. This step is where you decide how creamy and rustic your mashed sweet potatoes will be.
Step 7: Mix in Your Favorite Add-ins
Now is the time to personalize your dish. Stir in any add-ins like cinnamon for warmth, nutmeg for spice, a drizzle of maple syrup for sweetness, or even a bit of smoked paprika for a hint of smoky complexity. Mix well to evenly distribute flavors.
Step 8: Serve Warm and Enjoy
Serve your beautifully mashed sweet potatoes immediately while warm. If not serving right away, the Instant Pot’s “keep warm” mode will keep them cozy for up to an hour—just remember to give them a good stir now and then, and thin with more half and half if they start to thicken.

Side Dishes
Instant Pot Mashed Sweet Potatoes Recipe pairs beautifully with roast poultry like turkey or chicken, falls right in step with pork chops or seared steak, and even shines alongside a hearty vegetable main course. Its sweet, creamy profile is a versatile companion for many meals.

Make Ahead and Storage
Storing Leftovers
Keep any leftover mashed sweet potatoes in an airtight container in the refrigerator for up to 4 days. Before sealing, ensure the mash has cooled to room temperature to maintain freshness and prevent condensation inside the container.
Freezing
You can freeze the mashed sweet potatoes if you want to prep ahead. Portion into freezer-safe bags or containers, removing as much air as possible. Freeze for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator.
Reheating
Reheat your leftovers gently in a microwave or on the stovetop with a splash of half and half to bring back that creamy texture. Stir frequently to ensure even heating and to prevent drying out. Using the Instant Pot’s sauté function also makes reheating a breeze.
FAQs
Can I use regular potatoes instead of sweet potatoes?
Yes, but keep in mind that regular potatoes have a different flavor and texture. This recipe is designed to highlight the unique sweetness and creaminess of sweet potatoes, which regular potatoes won’t replicate exactly.
Is it possible to make this recipe dairy-free?
Absolutely! Swap out the half and half and butter for coconut milk and dairy-free margarine or oil. The sweet potatoes will still be rich and creamy with these substitutions.
What add-ins work best with Instant Pot Mashed Sweet Potatoes Recipe?
Cinnamon, nutmeg, maple syrup, and even a pinch of cayenne or smoked paprika are popular add-ins. They enhance the natural sweetness or add a subtle kick, making the mash more exciting.
Can this recipe be doubled or halved?
Yes! The Instant Pot adapts well to changes in quantity, but cooking time may need slight adjustment if doubling. Just make sure not to overcrowd the pot so the steam can circulate properly.
How do I prevent the mash from becoming gluey?
To maintain fluffy mashed sweet potatoes, avoid overblending. Use a potato masher or pulse briefly with a blender to preserve texture without turning it gluey.
