Crock Pot Sweet Potato Casserole Tips:

  • 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.

Variation Ideas:

  • 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.
