Ingredients
  

For the mashed sweet potatoes
  • 3 lbs sweet potatoes peeled and cut into 1.5 inch chunks
  • 1 cup water for a 6-quart pot; see notes for pot size adjustments
  • 4 tbsp unsalted butter or 3 tbsp butter + 1 tbsp cream for richer mash
  • 1/3 cup heavy cream or milk start with 1/3 cup and add more to taste
  • 1/2 tsp salt plus more to taste
  • 1/4 tsp black pepper
  • 1/4 tsp cinnamon or my Moroccan Seasoning optional but recommended
  • 1 tsp maple syrup or brown sugar optional; enhances natural sweetness
Optional flavor add-ins
  • 1 tsp vanilla extract for a holiday flavor
  • 1 tbsp bourbon for a deeper caramel note
  • 2 tbsp sour cream for tangy ultra-creamy texture
Savory variation
  • add 1 large grated garlic clove
  • add 1 tsp chopped fresh rosemary or thyme or 1/4 tsp dried
  • omit cinnamon and maple
Dairy-free variation
  • replace butter with 3 tbsp vegan butter
  • replace cream with 1/4 to 1/3 cup canned coconut milk

Equipment

  • Instant pot or electric pressure cooker: for quick, even cooking
  • Vegetable peeler: to peel sweet potatoes
  • Chef’s knife and cutting board: to cut potatoes into even chunks
  • Colander to drain excess water
  • Potato masher: gives fluffy texture without overworking
  • Liquid measuring cup: to measure cream or milk accurately

Method
 

  1. Add the sweet potato chunks and 1 cup water to the instant pot. Do not use a trivet. The potatoes steam directly in the water for better texture.
  2. Seal the lid. Set to manual or high pressure for 10 minutes.
  3. Natural release for 5 minutes, then quick release the rest. Potatoes should be very soft and easily pierced with a fork. If not, cook for 2 to 3 more minutes.
  4. Drain the potatoes thoroughly using a colander. Excess water will make the mash loose or gummy. Return the drained potatoes to the warm pot. The residual heat helps evaporate any extra moisture.
  5. Add butter, 1/3 cup cream or milk, salt, pepper, cinnamon (if using), and maple syrup (if using). Mash with a potato masher until smooth and fluffy. Taste and adjust seasoning.
  6. Turn on Keep Warm mode and hold for up to 1 hour, stirring occasionally to maintain texture.

Notes

  • Even cuts matter: cut potatoes into uniform 1.5 inch chunks for even cooking and consistent texture.
  • Water ratio by pot size: 6-quart pot = 1 cup water. 8-quart pot = 1.25 cups water.
  • Scaling tips: for 4 lb potatoes, increase water to 1.25 cups and pressure cook 11 minutes.
  • Avoid gummy texture: do not use an immersion blender. Sweet potatoes overwork easily and become sticky.
  • Savory mashed sweet potatoes: add garlic and herbs with the butter and cream, and omit maple and cinnamon for a dinner-friendly variation.
  • Dairy-free option: coconut milk and vegan butter make an exceptionally creamy mash with natural sweetness that pairs well with sweet potatoes.
  • Moroccan seasoning option: My Moroccan Seasoning includes cinnamon and aromatic spices that naturally complement sweet potatoes. Start with 1/2 tsp for lightly spiced mash or 1 tsp for a deeper, warm flavor. It works in both sweet and savory versions.
  • Make ahead: store in the fridge for up to 4 days. Reheat in a pot over low heat, adding a splash of milk or cream as needed.
  • Freezer friendly: freeze cooled mashed sweet potatoes in portions for up to 2 months. Thaw overnight and reheat gently.
