  • 2 ½ pounds (1025g) sweet potatoes , roughly cut into 2” chunks
  • 3 tablespoons (40g) ginger slices (use old ginger & adjust amount accordingly)
  • 4 cups (1L) cold water
  • A pinch salt
  • 1 piece (93g) brown sugar in piece (Chinese: 片糖)


  • Pressure Cook Chinese Sweet Potato Soup: Add 1 (93g) brown sugar in pieces (片糖), a pinch of salt, and ginger slices in Instant Pot Pressure Cooker. Add in 2 ½ lbs (1025g) sweet potato chunks, then pour in 4 cups (1L) cold water. Ensure the sweet potato chunks are submerged in the water. Close lid and turn Venting Knob to Sealing position. Pressure Cook at High Pressure for 1 minute, then 5 minutes Quick Release. After 5 minutes, release the remaining pressure by turning the Venting Knob to the Venting position.

  • Thicken Chinese Sweet Potato Soup: The Sweet Potato Soup will look quite watery. It's important to bring the sweet potato soup back to a simmer by pressing the "Cancel" button, then "Saute" button. Let it simmer. Break down the sweet potatoes slightly with a wooden spoon, then mix the soup to give it more body. This will take a few minutes. Taste and adjust the sweetness by adding more brown sugar in pieces if necessary.
  • Serve Instant Pot Chinese Sweet Potato Soup: Discard the ginger slices. Serve this Chinese Sweet Potato Soup hot or cold. If you are serving it cold, add a bit more sugar. Enjoy~


  1. Brown Sugar in Pieces (Chinese: 片糖): Try to find them in your local Asian markets as they'll be much cheaper! :)
  2. Ginger: Use old ginger for a stronger & more aromatic taste. If you enjoy a more gingery spicy Sweet Potato Soup, feel free to add more ginger slices according to your preferences.
