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.

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.

Add eggs.

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.
