Ingredients You’ll Need
These simple ingredients transform into the creamiest sweet potato mash.
Sweet potatoes
- You’ll need 3 pounds of peeled sweet potatoes cut into 1.5 inch chunks.
- Uniform size gives you even texture and prevents overcooked edges.
Butter, cream, and seasonings
- A combination of butter and cream gives the mash its silky body.
- Salt and pepper balance the natural sweetness, and cinnamon adds warmth if you choose to use it.
Optional add-ins for flavor
- Maple syrup enhances natural sweetness.
- Vanilla or bourbon creates a deep holiday note.
- Sour cream adds tang and extra creaminess.
- Garlic and herbs transform the dish into a savory variation.
If you want a deeper, warm spice profile without making the mash taste like dessert, my Moroccan Seasoning is incredible with sweet potatoes. It includes cinnamon and aromatic spices that enhance natural sweetness while still keeping the dish savory.
How To Make Instant Pot Mashed Sweet Potatoes
Follow these simple steps for consistent results every time.
Load the Instant Pot
Add the sweet potato chunks and 1 cup water to the Instant Pot. Skip the trivet. Cooking the potatoes directly in the water ensures even steaming and a fluffier mash.
Pressure cook the sweet potatoes
Seal the lid. Set to manual or high pressure for 10 minutes. Allow a natural release for 5 minutes, then quick release the remaining pressure.
Your potatoes should be very soft and easily pierced with a fork. If they’re not fully tender, pressure cook 2 to 3 minutes more.
Drain well
Drain the potatoes thoroughly in a colander. Any excess water will make the mash loose or gluey. Return the potatoes to the warm pot so the residual heat can evaporate any remaining moisture.
Mash and season
Add butter, cream or milk, salt, pepper, cinnamon, and maple syrup if using. Mash gently with a potato masher until smooth and fluffy. Taste and adjust. Add more cream for richer mash, more salt for balance, more cinnamon for warmth, or a bit more maple for a deeper sweetness.
For a more complex warmth, add 1/2 tsp of my Moroccan Seasoning. It gives the mash a cozy, spiced depth that’s not overly sweet.
Keep warm until serving
Turn on Keep Warm mode and hold for up to 1 hour. Stir occasionally to maintain a smooth texture.
Flavor Variations
Classic lightly sweet mash
Butter, cream, a small amount of maple syrup, and cinnamon create the perfect weeknight or holiday flavor.
Savory garlic and herb mash
Add grated garlic and rosemary or thyme, and omit maple and cinnamon. This version pairs well with roasted meats, chicken, and pork chops.
Add 1/2 to 1 tsp Moroccan Seasoning to create a gently spiced flavor that pairs well with chicken, salmon, or roasted vegetables. It gives the mash a gourmet feel with zero extra effort.
Holiday vanilla maple mash
Add a splash of vanilla and a touch more maple for a cozy flavor that complements turkey or ham.
Dairy-free coconut mash
Use coconut milk and vegan butter for a naturally sweet, ultra-creamy mash. Coconut pairs beautifully with sweet potatoes.
Expert Tips for the Best Instant Pot Mashed Sweet Potatoes
- Cut the potatoes into consistent 1.5 inch chunks to ensure even cooking.
- Do not use an immersion blender. Sweet potatoes become gummy when overworked.
- Adjust water based on pot size. Use 1 cup for a 6-quart Instant Pot and 1.25 cups for an 8-quart.
- If the mash is too thick, add a splash of cream. If it’s too thin, heat it on sauté mode for 1 to 2 minutes to evaporate excess moisture.
- You can scale up to 4 pounds of potatoes by increasing the water to 1.25 cups and cooking for 11 minutes.
Make Ahead, Storage, and Reheating
- You can make these instant pot mashed sweet potatoes up to 24 hours ahead for busy holidays.
- Store in an airtight container in the fridge for up to 4 days.
- Reheat on the stove with a splash of milk or cream to restore creaminess. You can also reheat in the microwave, stirring every 30 seconds.
- Sweet potatoes freeze surprisingly well. Freeze in portions for up to 2 months and thaw in the refrigerator before reheating.
What To Serve With Mashed Sweet Potatoes
- These pair well with roasted chicken, pork tenderloin, baked salmon, meatloaf, or any comforting weeknight dinner.
- They also hold their own on a holiday table next to turkey, ham, brisket, or stuffing.
