Recipe ingredients

Mashed sweet potato recipe ingredients
  • Sweet potatoes: 3 lbs., peeled and cut into 2″ chunks. Any variety will work, though textures vary slightly by type.
  • Half and half: 1/3 cup. Substitute whole milk, heavy cream, or a non-dairy milk. Heavy cream yields richer mashed potatoes; coconut milk or almond milk make a dairy-free version.
  • Unsalted butter: 4 tablespoons, softened. Use vegan butter or olive oil to keep the recipe dairy-free.
  • Orange zest: 1 tablespoon for bright citrus flavor. Omit if you prefer a purely savory mash.
  • Fresh rosemary: 2 tablespoons, finely chopped. You can substitute parsley, chives, or 1 teaspoon dried herbs if fresh is unavailable.
  • Salt and pepper: To taste.

How to make this mashed sweet potato recipe

You can prepare these mashed sweet potatoes two ways: in the Instant Pot or on the stove top. The techniques are similar; Instant Pot cooking requires less water and is more hands-off, while stove top cooking follows a traditional simmer-and-drain method.

Pro tip: Avoid overcooking the sweet potatoes so they don’t become watery. Drain them well in a colander before mashing to keep the texture thick and creamy.

Instant Pot mashed sweet potatoes instructions

The Instant Pot makes perfectly tender sweet potatoes with minimal effort, and they mash up smooth every time.

  1. Place the sweet potato chunks into the Instant Pot and add 1 cup of water. Secure the lid and set to Pressure Cook (High) for 8 minutes.
  2. When the cook time ends, perform a quick pressure release and open the lid when it is safe to do so.
  3. Drain the sweet potatoes thoroughly in a colander to remove excess water.
  4. Return the drained sweet potatoes to the Instant Pot or a large bowl and mash them with a potato masher until mostly smooth.
  5. Stir in the half and half, butter, orange zest, and chopped rosemary. Season with salt and pepper to taste and mix until well combined.
  6. Adjust consistency with extra milk or cream if desired, then serve warm.

Stove top mashed sweet potato recipe instructions

If you prefer a traditional method, cook the sweet potatoes on the stove top in a large pot of boiling water.

  1. Place sweet potato chunks in a large pot and add enough cold water to cover by about 1 inch. Cover and bring to a boil over high heat.
  2. Once boiling, remove the lid, reduce heat to medium, and simmer until the sweet potatoes are tender when poked with a fork, about 10–15 minutes.
  3. Drain completely in a colander and return the drained potatoes to the pot.
  4. Mash with a potato masher, then stir in the half and half, butter, orange zest, chopped rosemary, and salt and pepper to taste.
  5. Serve warm and adjust seasoning as needed.

Tips for success

  • Cut the potatoes into uniform pieces so they cook evenly.
  • Drain well after cooking to prevent a watery mash.
  • Avoid overcooking, which can produce a mealy or mushy texture.
  • For the smoothest consistency, purée with an immersion blender or food processor, but be careful not to overwork them or they can become gluey.
  • To make ahead: keep the mash warm in the Instant Pot on Keep Warm, or place the covered pot in a larger pan with a couple inches of simmering water until ready to serve, stirring occasionally.

Mashed Sweet Potatoes (Instant Pot, Stove Top)

Servings: 6   |   Prep Time: 10 mins   |   Cook Time: 8 mins (Instant Pot)   |   Total Time: 28 mins

These mashed sweet potatoes are creamy, lightly sweet, and infused with orange zest and rosemary. The recipe includes both Instant Pot and stove top methods.

Equipment

  • 6–8 quart pot or Instant Pot (6 quart works well)
  • Potato masher or immersion blender

Ingredients

  • 3 lbs. sweet potatoes, peeled and cut into 2″ chunks
  • 1/3 cup half and half (room temperature)
  • 4 tablespoons unsalted butter, softened
  • 1 tablespoon orange zest
  • 2 tablespoons freshly chopped rosemary (or 1 tsp dried)
  • Salt and pepper, to taste

Stove top instructions

  1. Place sweet potatoes in a large pot and add enough water to cover by 1″. Cover and bring to a boil. Remove lid and reduce heat to medium; simmer 10–15 minutes until tender. Drain completely.
  2. Return potatoes to the pot and mash with a potato masher until you reach the desired consistency. Stir in half and half, butter, orange zest, rosemary, salt and pepper. Adjust seasoning and serve.

Instant Pot instructions

  1. Place sweet potato chunks in the Instant Pot and add 1 cup of water. Secure the lid and set to High Pressure for 8 minutes (the pot will take additional time to come to pressure).
  2. Quick release the pressure when the cook time ends. Drain the sweet potatoes very well in a colander, then return to the Instant Pot or a bowl and mash.
  3. Stir in half and half, butter, orange zest, rosemary, salt and pepper. Taste and adjust seasoning as needed; serve warm.

Notes

  • Don’t overcook—overdone sweet potatoes can become watery. Drain well before mashing.
  • Substitute half and half with whole milk, cream, buttermilk, or non-dairy milk to change richness or make the dish dairy-free.
  • Customize by adding roasted garlic for savory depth, or a touch of maple syrup and cinnamon with toasted pecans for a sweeter side.
  • To keep warm, use the Instant Pot Keep Warm setting or place the covered pot in a water bath over low heat, stirring occasionally.
