Instant Pot Sweet Potato Casserole 

Sweet potato casserole in Instant pot saves so much time. Granted I did pop this in the oven to toast the marshmallows, but that is totally optional! I was shocked at how fast the potatoes got tenderized in the pressure cooker.

Do You Peel Sweet Potatoes For Sweet Potato Casserole

I did not peel my potatoes for this recipe. If you want to take the extra step and peel go right ahead. But since sweet potatoes have a pretty soft skin they will break down well in the Instant Pot. 

I wanted a creamy sweet potato casserole and you can see that is what I got! So feel free to do whatever you need. 

How Many Sweet Potatoes Equals 6 Cups 

I used 2 larger sweet potatoes to make my 6 cups of sweet potatoes mark. Now if you used smaller sweet potatoes you will want to use more than just 2. 

Then just cube up the sweet potatoes trying to cut in similar size so they all cook up about the same.

How Long To Cook Instant Pot Sweet Potato Casserole 

4 minutes is all it takes on manual high pressure! Now, take into account you need to allow your Instant Pot to come to pressure. If you don’t then you will be upset you didn’t factor that time in. Normally your Instant Pot will come to pressure within 5-12 minutes. Mine was around 7 minutes for this. 

How Do You Toast Marshmallows In Sweet Potato Casserole 

I tossed in the oven under the broiler for 2-4 minutes. I just watched it close to give it that golden brown color you know and love with toasted marshmallows. 

Can You Freeze Sweet Potato Casserole 

Of course, you can freeze this casserole for later. If you are going to do that, what I would recommend is pouring the sweet potato mixture into the casserole and then covering and storing in the freezer. Then when you remove to bake in the oven, top with marshmallows and nuts and then warm it up in the oven covered, and once warm, remove the aluminum foil, then turn to broil to toast marshmallows. 

This will freeze for up to three months. 

Can I Make Instant Pot Sweet Potato Casserole Ahead Of Time 

Yes, just like freezing assemble the sweet potato mixture in the pan, then top with marshmallows and nuts and cover. Store in the fridge for up to 24 hours. Then warm in the oven covered in aluminum foil. Once warm remove aluminum foil and broil until marshmallows are browned, this will take a minute or two.

How Long Can Sweet Potato Casserole Store In The Fridge 

You can store your casserole in the fridge for 3-5 days when it is covered properly. You can warm it up in the microwave or heat in the oven to reheat it.
