Sweet potato casserole. A low-key guilty pleasure of mine during the holidays.

No wait, it’s really the slightly burnt, crispy mini marshmallows and the crunchy, buttery, sweet pecan streusel on top with just the tiniest bit of mashed sweet potato in the mix. Yup, that’s what we’re looking for here.

And with the help of the pressure cooker, your sweet potatoes will be ready to be mashed in just 8 minutes (no pre-boiling, no nothing), leaving your valuable oven and stovetop real estate free and empty as you prep for the rest of your holiday dishes.

tips and tricks for success

  • Sweet potatoes are not yams. Sweet potatoes and yams are used interchangeably but the two are different vegetables. Sweet potatoes are indeed sweeter than yams.
  • Use cold water. Start with cold water in the Instant Pot. The starch in the potatoes will react to hot water immediately, resulting in uneven cooking and mealy potatoes.
  • Drain the sweet potatoes. Nobody likes a watery sweet potato casserole. Drain the potatoes very well prior to mashing.
  • Make ahead of time. Sweet potato casserole is another one of those holiday side dishes you can make ahead of time. Prep and cook the sweet potatoes in the Instant Pot the night before, assembling in the baking dish, and place in the fridge. Allow the sweet potato mixture to come to room temperature for about 15-30 minutes prior to baking.

Instant Pot Sweet Potato Casserole: Frequently Asked Questions

Can I skip the eggs?

The eggs in the recipe work as a binder, but they can be omitted as needed, resulting in a little bit of a “looser” texture.

What other nuts can I use?

Walnuts would work very well here.

Can I make sweet potato casserole ahead of time?

Yes! The sweet potatoes can be prepped and made in the Instant Pot the night before and placed in the fridge overnight.

Can I freeze sweet potato casserole?

Absolutely! Sweet potato casserole freezes very well without the topping. Once the sweet potatoes have been cooked in the Instant Pot, assembled in the baking dish and cooled completely, cover the casserole tightly with plastic wrap, then aluminum foil, freezing up to 3 months. To bake, thaw overnight in the fridge, adding the pecan mixture and baking as directed.
