Crockpot Sweet Potato Casserole is everything it sounds like and the perfect set it forget version of a traditional Sweet Potato Casserole! The potatoes do not need to be boiled first, all of the cooking happens right in the slow cooker!

Serve alongside all of the classic Thanksgiving sides. Like the best mashed potatoes, a cheesy green bean casserole, and of course the classic Thanksgiving stuffing. It’s a perfect addition!

Prepping Sweet Potatoes for Casserole

It’s important to remove the tough skin from the sweet potatoes.

  1. Rinse sweet potatoes and peel them entirely.
  2. Cut into uniform cubes so they cook evenly, in this case, 1” cubes.

And, that’s it. Just toss them in the crockpot and get ready for a delicious side dish!

How Long to Cook Sweet Potato Casserole in a CrockPot

Depending on how quickly you want them finished you can either cook them on high or low.

  • Low: Cook them overnight or while at work on low for 8 hours.
  • High: If you are in a bit of a hurry, cook them on high for about 4 hours.

Either method will yield perfectly cooked, creamy sweet potatoes! Don’t forget to add the pecan topping at the end!

To Mash Sweet Potatoes

You can serve these as smashed (with little chunks) or mashed sweet potatoes (nice and smooth). Use a potato masher for a smashed texture, if you’d like the really smooth, use a hand mixer or an immersion blender.

I use a buttery brown sugar pecan topping. If you’d like to add marshmallows, simply add to the slow cooker and close the lid for 5 minutes or so. They will melt/soften.

A streusel topping is great on this too, combine

How to Store Leftovers

Refrigerator: Store leftovers in the fridge for up to 5 days!

Freezer: Sweet Potato Casserole can easily be frozen. Scoop it into a zippered bag or a freezer container and be sure to label it with the date.

Reheat: When you are ready to reheat, simply give it a stir, maybe give it an extra dash of pumpkin pie spice and pop it in the microwave!
