Free up oven space by making this Instant Pot Sweet Potato Casserole instead. I’ve been experimenting with ways to put my Instant Pot to good use this Thanksgiving and I had great results with this casserole.
I’m a huge sweet potato fan and I especially love this classic casserole since it’s a dessert dish that passes as a side. Did I mention I have a serious sweet tooth?
The Instant Pot works great on potatoes and sweet potatoes, plus it locks in all those great nutrients. And, in this version of Instant Pot Sweet Potato Casserole, you’ll actually make two pans so you can keep one on warm in the Instant Pot until the first pan runs out.
What You’ll Need
The recipe for Instant Pot Sweet Potato Casserole is very similar to the oven version. For the casserole itself, you’ll need:
- Sweet potatoes
And for the topping (which, face it, is the main way we win the kids over) you’ll need:
- Brown sugar
- More butter
- Chopped pecans
- Instant Pot
- Steamer basket
- Stackable insert pans
- Large bowl
- Small bowl
- Potato masher
How to Make Instant Pot Sweet Potato Casserole
The ingredients for Instant Pot Sweet Potato Casserole are similar to traditional sweet potato casserole. It’s in how we work with these ingredients where things take a different turn.
It’s not hard, we’re just going to let the Instant Pot play a starring role.
Step 1: Cook the potatoes
We need to soften up those sweet potatoes before we can mash them. So, first, we need to place them on a steamer rack and put them in the Instant Pot (don’t forget to add water to the bottom of the pot).
Pressure cook them on manual high pressure for 22 minutes. Quick release the pressure when the timer beeps.
Once the pressure has fully released, carefully remove the cover and lift out the sweet potatoes.
Step 2: Prepare casserole
Carefully remove the peels from the sweet potatoes (they should peel off easily). Then, place them in a large bowl and use your potato masher to break them up.
Also add sugar, butter, and heavy cream. Then, use the masher to combine the ingredients.
When you’re done mashing, your sweet potato mixture should look like this:
Pour the sweet potato mixture into a stackable pan. If you follow the recipe card below, you’ll actually need to use both pans.
Step 3: Prepare topping
Now it’s time to make that deliciously sweet, crumbly topping. In a small bowl, combine brown sugar, melted butter, flour, and chopped pecans.
Spread the topping evenly over the stackable pan(s).
Step 4: Pressure cook
Before lowering your casserole dish into the Instant Pot, add a cup of water to the inner liner. Then, insert the pans.
Secure the lid, making sure the valve is set to sealing. Press “Manual” and set the time for 20 minutes. When time is up, do a quick release of the pressure.
Remove the pans from the Instant Pot and transfer to a serving dish. Top with additional chopped pecans, if you prefer.
If you expect your Thanksgiving feast to last a while, leave one pan in the Instant Pot on warm and retrieve it when the first batch is almost gone.

Like exact measurements? Me too! Here are the details for this Instant Pot Sweet Potato Casserole.
Instant Pot Sweet Potato Casserole
- 3 pounds sweet potatoes
- 1 ½ cups granulated sugar
- 1/3 cup butter melted
- 3 eggs
- 1/3 cup heavy cream
- 1 ½ cups brown sugar
- 5 tablespoons butter melted
- 2/3 cup all-purpose flour
- 1 ½ cups pecans chopped
- 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.
- 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.
- In a separate bowl, mix together the topping ingredients.
- 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.
