Sweet potato casserole with marshmallows in crock pot

Slow Cooker Sweet Potato Casserole: Flavorful sweet potatoes topped with candied nuts and gooey marshmallows. The slow cooker makes this dish nearly effortless!

I love this decadent slow cooker sweet potato casserole. It basically cooks itself while you worry about your turkey, and other fixings!

The sweet potatoes are boiled, and the casserole is made right in your crockpot! However, if  you want it NOW (and I don’t blameyou),you can also make it in the oven. (See directions below.)

I like to pop my crockpot sweet potato casserole under the broiler to toast the marshmallows at the end, but you certainly don’t have to. You could just add the marshmallows into the crockpot instead. They’re still get ooey gooey, just not browned.
