Why do we all love holiday slow cooker side dishes so much?  Because we can set it, forget it and just walk away and focus on all the other craziness that holiday cooking brings. 

That’s the beauty of this sweet potato casserole, you simply stir your ingredients together and move on to other things like spending time with your family … or trying to hide from your family … whichever works for your particular situation.  No judging..

This casserole tastes like you slaved away all day in your kitchen but it only takes about 10 minutes to pull this together.  Shhhh … it will be our secret!

Nothing in your house (including most of your invited family) will help you more. I feel like the other appliances in my kitchen aren’t even trying at this point.

PRO TIPS FOR PERFECT SWEET POTATO CASSEROLE

  • Don’t want to serve this with both a marshmallow and a pecan topping?  Leave out whichever you don’t prefer and your sweet potato casserole will still be delicious.
  • This sweet potato casserole filling can be made the night before and then added into your slow cooker the day of.  
  • Don’t skip the orange juice – it gives the sweet potatoes a little bit of “zing”! 

SWEET POTATO CASSEROLE WITH PECANS OR MARSHMALLOWS?

Whether to make sweet potato casserole with marshmallows or sweet potato casserole with pecans, that’s dealers choice. 

I, personally, prefer sweet potato casserole with pecans whereas my hubby likes marshmallows. 

The addition of BOTH pecans and marshmallows really add a crunchy, sweet topping to your casserole that pairs perfectly with the mashed sweet potatoes.

For this Slow Cooker Sweet Potato Casserole, I combined the best of both worlds to avoid any awkward holiday fighting but feel free to customize this recipe to however your family likes it.

CANNED YAMS VS FRESH SWEET POTATOES

Sweet potatoes vs. yams is a sweet potato casserole discussion that usually results in heated arguments and hurt feelings. Haha.. just kidding. 

You most certainly can use fresh sweet potato to make your sweet potato casserole dish.  Simply peel, chop and boil four large sweet potatoes until they are soft enough to mash. Then follow on with the rest of the instructions.

For this Slow Cooker Sweet Potato Casserole recipe, I used the canned sweet potatoes to make this slow cooker side dish recipe as easy and flavorful as possible. I’ve tried making this side dish with both and I personally prefer using the canned sweet potatoes over fresh potatoes.

  1. I’m confused because in the casserole ingredients list you have the allspice and the cinnamon and in the toppings list it does not say anything about cinnamon or allspice however in the instructions you say to after I have smoothed out the casserole add in the topping ingredients and mix together and in that topping ingredients list you have cinnamon and spices so does the cinnamon go in the casserole or does it go in the topping mixture what is it going both
