Equipment

  • Instant Pot
  • Steamer basket
  • Stackable insert pans or casserole dish

Ingredients

Potatoes:

  • 3 pounds sweet potatoes
  • 1 ½ cups granulated sugar
  • cup butter melted
  • 3 eggs
  • cup heavy cream

Topping:

  • 1 ½ cups brown sugar
  • 5 tablespoons butter melted
  • cup all-purpose flour
  • 1 ½ cups pecans chopped

Instructions

  • Place potatoes in a steamer basket over 1 cup water in the inner pot of your Instant Pot. Secure lid and set valve to sealing. Press "Manual" and set time for 22 minutes. When the cook time has finished, move the valve to venting to quick release the pressure. After the pressure has fully released remove the sweet potatoes from the Instant Pot.
    3 pounds sweet potatoes
  • Carefully remove peelings and mash in a large bowl with a potato masher (if you don't have one, you can use a fork). Add in the sugar, butter, eggs and heavy cream and mix together until smooth.
    1 ½ cups granulated sugar, ⅓ cup butter, 3 eggs, ⅓ cup heavy cream
  • In a separate bowl, mix together the topping ingredients.
    1 ½ cups brown sugar, 5 tablespoons butter, ⅔ cup all-purpose flour, 1 ½ cups pecans
  • Place potatoes in a casserole dish or pan that fits into the Instant Pot (it is okay to divide between two pans) and then cover with the topping.
  • Add 1 cup of water to the inner pot of the Instant Pot and then lower the casserole dish into the inner pot on a trivet. Cook on high pressure for 20 minutes and allow for a quick release of pressure when the cooking time has finished.

Notes

Recipe FAQs

How can I make this recipe dairy-free?
Substitute coconut oil or vegan butter for the butter, and use coconut cream or almond milk in place of the heavy cream. Ensure any dairy-free replacements have a similar consistency to maintain the texture of the filling.
 
Can I reduce the sugar in this recipe?
Yes, you can reduce the sugar in both the filling and the topping. For the filling, try reducing it to 1 cup or even ¾ cup of granulated sugar. For the topping, you can use 1 cup of brown sugar instead of 1 ½ cups. Keep in mind that this may alter the sweetness and texture slightly.
 
How do I reheat leftovers?
To reheat the casserole, cover it with foil and bake at 350°F (175°C) until heated through (about 15-20 minutes). You can also reheat individual portions in the microwave.
