Crockpot Sweet Potato Casserole is a fun twist on a classic dish. Free up your oven space and make it in the slow cooker.
Tasty pecans and marshmallows in every bite make this the perfect casserole to enjoy. We have a traditional Oven Baked Sweet Potato Casserole we love to make, but this recipe is a bit different because the potatoes are diced and not mashed.
Making it in the slow cooker is a total game changer because it saves oven space and keeps the casserole perfectly warm until serving. It’s the perfect blend of buttery mashed sweet potatoes and that golden, nutty pecan topping everyone fights over. Whether you serve it for Thanksgiving dinner or a holiday potluck, it’s guaranteed to steal the spotlight!

Recipe Notes
- If you have a lot of other things to cook, it is helpful to do the prep work in advance. By going ahead and peeling and dicing the potatoes.
- Make sure to peel the sweet potatoes entirely. The skin adds a toughness to the casserole so make sure to remove all the skin will peeling.
- Dice the sweet potatoes into even pieces. This will ensure that the sweet potatoes cook evenly. Try to get them in as even as sizes as possible.
- Leave the lid off at the end of cooking time. – I do remove the lid from the crock pot for the last 15-20 minutes so any extra moisture will cook off.
- Chopped Nuts – The pecan topping in the recipe is optional. It will also be good with any of your favorite type of nuts. Walnuts or almonds would be great too.
- Marshmallows – We used mini marshmallows but you can use regular size marshmallows as well. I think either one would be delicious.
- Mashed Sweet Potatoes – You can mash the sweet potatoes. This recipe leaves the potatoes diced. However, if you prefer you can use a potato masher and mash them.
- Add Sweetness – If you like things sweeter, add a little bit of maple syrup or honey to the sweet potatoes before cooking.
