Instant Pot Sweet Potato Filling

Things You'll Need

  • 6 medium sweet potatoes, peeled and sliced

  • 1 cup water

  • 2 eggs

  • 1/4 cup milk (dairy or plant-based)

  • 1/2 cup brown or white sugar

  • 1/4 cup unsalted butter

  • 1 teaspoon cinnamon

  • 1/2 teaspoon salt

  • 1 teaspoon vanilla extract

Step 1

To the Instant Pot, add the sweet potatoes and water. Seal the lid and press the "Manual" or "Pressure Cook" button. (The exact button will depend on the model of your Instant Pot. "Manual" means pressure cooking.) Set the timer to 8 minutes on "High." The Instant Pot will take about 10 minutes to reach the appropriate pressure and then it will begin the countdown.

After 8 minutes, the Instant Pot will beep. Do a "Quick Release" by pressing the steam-release button or moving the valve. Keep your hands and face away from the top of the Instant Pot, as it will release a rapid stream of pressure.

Step 2

Carefully drain the sweet potatoes. Use caution when handling the pot, as it will be very hot. Mash the potatoes with a vegetable masher until smooth.

Tip

Keep the sweet potatoes in the pot to minimize dirty dishes. You can also transfer the potatoes to a large bowl if you'd like.

Step 3

Slice and add the butter, which should melt as you stir. You can also melt the butter separately before mixing it in.

Tip

If you'd like a finer crumble topping, chop the pecans very well. You can also grind them in a food processor. If you don't have pecans, use almonds or walnuts instead.
