Baked sweet potatoes are always welcome at my table, but some nights call for something faster, easier, and more hands-off. These Instant Pot mashed sweet potatoes are a simple, creamy side dish that works just as well for a weeknight dinner as it does for Thanksgiving, Christmas, or any holiday meal.
This recipe turns tender sweet potatoes into a smooth, buttery mash with a little maple syrup for natural sweetness and a touch of chili powder for gentle warmth. The flavor is balanced, cozy, and not overly sweet. It is also completely dairy free and vegan when made with non-dairy milk and vegan butter, so it is a great option for serving a variety of guests.
One of the best things about making mashed sweet potatoes in the Instant Pot is how convenient it is. The pressure cooker softens the potatoes quickly, and once they are mashed, you can leave them on the Keep Warm setting until dinner is ready. That makes this recipe especially helpful when oven space is limited or you are preparing several dishes at once.
If you need a reliable sweet potato side dish that is creamy, flavorful, and easy to prepare ahead of time, this Instant Pot mashed sweet potatoes recipe is a great choice.
Ingredient Notes
You only need a short list of everyday ingredients to make these creamy mashed sweet potatoes. Each ingredient adds something important to the final texture and flavor.
- Sweet Potatoes – Orange sweet potatoes create the classic color and naturally sweet flavor. Peel them and cut them into large, even chunks so they cook evenly in the Instant Pot. White or purple sweet potatoes can also be used, although the flavor and color will be slightly different.
- Water – The water creates steam inside the pressure cooker, helping the sweet potatoes become tender.
- Salt – Salt balances the natural sweetness of the potatoes and keeps the finished mash from tasting flat.
- Non-Dairy Milk – Unsweetened carton coconut milk gives the potatoes a creamy texture without adding dairy. You can use any plain, unsweetened non-dairy milk you enjoy. If you are not dairy free, whole milk or half and half may be used in the same amount.
- Vegan Butter – Vegan butter adds rich, buttery flavor and helps make the mash smooth. Regular unsalted butter may be used if you do not need the recipe to be dairy free.
- Maple Syrup & Chili Powder – Maple syrup enhances the natural sweetness, while chili powder adds a mild savory note. Neither flavor is overpowering; together they make the sweet potatoes taste fuller and more balanced.

Substitutions & Variations
- Not Dairy Free – Use regular butter and dairy milk in the same measurements.
- Savory Herb Mash – Stir in rosemary, thyme, or sage for a more savory holiday-style side dish. Fresh herbs are lovely, but dried herbs also work well.
- Garlic Infusion – Mix in roasted garlic cloves for a mellow garlic flavor that pairs beautifully with sweet potatoes.
- Nutty Topping – Add toasted chopped pecans or walnuts before serving for crunch and extra richness.
- Citrus Zest – Add a little orange or lemon zest for a brighter, fresher flavor.
- Spicy Kick – Add a pinch of cayenne pepper or red pepper flakes if you prefer a little more heat.
- Cheesy Version – Stir in a small amount of vegan cheese or regular cheese, such as cheddar, goat cheese, or parmesan, for added creaminess and depth.
- No Maple Syrup – Brown sugar can be used as a substitute.
- Sweet Potato Casserole Style – Replace the maple syrup and chili powder with brown sugar, ground cinnamon, and marshmallows for a sweeter side dish inspired by classic sweet potato casserole.
How to Make Instant Pot Mashed Sweet Potatoes
To make this recipe, you will need an Instant Pot pressure cooker and either a potato masher, handheld mixer, or immersion blender. A masher gives the potatoes a more rustic texture, while a mixer makes them lighter and smoother.
STEP 1: Add the peeled and cut sweet potatoes, water, and 1 teaspoon of salt to the Instant Pot. Secure the lid, turn the valve to sealing, and cook on high pressure.
STEP 2: When the cooking time is finished, carefully quick release the pressure. The sweet potatoes should be fork tender. Drain the water, then mash the potatoes directly in the pot.
STEP 3: Add the remaining salt, warmed non-dairy milk, vegan butter, chili powder, and maple syrup to the mashed sweet potatoes.
STEP 4: Stir until the butter melts and everything is fully combined. Taste and add more salt if needed. Serve right away or keep warm until ready to eat.
Expert Tip
If you do not have a potato masher, use a handheld mixer or immersion blender to whip the cooked sweet potatoes. For the smoothest texture, warm the milk before adding it so the potatoes stay hot and creamy.
Storage
Store leftover Instant Pot mashed sweet potatoes in an airtight container in the refrigerator for 3 to 4 days. Reheat individual servings in the microwave for about 2 minutes, or until heated through and the internal temperature reaches 165°F. If the potatoes seem too thick after chilling, stir in a small splash of milk while reheating.
