Instant Pot Sweet Potato Casserole
Instant Pot Sweet Potato Casserole has the perfect combination of spices and is a super easy and fast way to make sweet potato casserole! Even better, you can prep it ahead of time and just put it in the oven to warm up right before the big meal.
While you can't make every dish in the Instant Pot during Thanksgiving (unless you have five Instant Pots!) it's really an amazing tool for making dishes faster and freeing up space in the kitchen. This recipe for Instant Pot Sweet Potato Casserole can even be made ahead of time, which means you can make it the day before and then make my Instant Pot Green Bean Casserole or Instant Pot Maple Mustard Turkey Breast the day of.
This Instant Pot Sweet Potato Casserole is definitely one of the highlights of my Thanksgiving plate. It is the perfect combination of lightly sweetened potatoes with a marshmallow/pecan crumble combination topping. I couldn't choose between a marshmallow topping and a pecan topping, so I did both!

Ingredients
Sweet Potatoes - I use 3-4 large sweet potatoes for this recipe.
Brown Sugar and Maple Syrup - the sweeteners for this sweet potato casserole.
Cinnamon and Vanilla - both add warmth to the dish.
Egg and Heavy Cream - binders in the filling.
Pecans - Add a lovely crunchy topping to the casserole.
Butter - in the filling and the topping.
Marshmallows - essential for sweet potato casserole topping!
Refer to the recipe card for the complete list of ingredients.
Variations
Omit the marshmallows. If you're not a fan of marshmallows on your sweet potatoes, you can definitely omit them. The addition of the pecan topping means the sweet potato casserole will still have a crunchy sweet top!
Boil the Potatoes. No Instant Pot? You can still make this sweet potato casserole by boiling the sweet potatoes instead. Simply boil them in water for 15-20 minutes, until tender.

Make Ahead Instructions
Okay, let's wrap up by talking about how this Instant Pot Sweet Potato Casserole can be made ahead of time (just like Cream Cheese Green Bean Casserole!). Basically, you'll do all of the Instant Pot prep in advance. This includes cooking the sweet potatoes and mixing it with the butter and spices.
Then you spread it in a casserole dish, make the brown butter and pecan topping, and finish it off! Wrap it with some plastic wrap and stick it in the fridge until you're ready to bake it. So easy. So simple. And so delicious! Then you have more time for the Mayonnaise Roasted Turkey and Turtle Pecan Cheesecake!
Recipe FAQs
I have never made this using canned sweet potatoes, but I suppose you could. You just would not need the Instant Pot to cook the sweet potatoes first. Simply start from the step of mashing the sweet potatoes.
Yes. Simply omit them and you will still have the sweet pecan topping.
Sure. You can omit the brown sugar (but keeping the maple syrup) from the filling. You definitely need to keep the sugar in the topping. This Sweet Potato Casserole is meant to be sweet.
