For Thanksgiving this year,

one of the dishes my youngest kiddo requested as a must-have…

was sweet potato casserole.

My kids love sweet potatoes with butter, cinnamon, and marshmallows.

Who can blame them?!

And when we did serve our famous sweet potato casserole at Thanksgiving this year,

my sister-in-law commented on how perfect the flavors are.

Not too sweet. Not too fancy of a production.

Just a simple sweet potato casserole where you can still taste the sweet potatoes,

in all their magnificent glory. 

This has definitely become a holiday staple for the extended family.

Kids love it. Adults love it. And leftovers are a must!

Did I mention nobody knows it’s dairy-free? Food allergy win!

But don’t just wait for a holiday!

This is a fantastic side dish for Sunday dinner or anytime.

When we have to feed a big crowd, like on Thanksgiving, we often make these sweet potatoes in a slow cooker.

The day before, we cook the potatoes and mix them with the butter and cinnamon.

Then we spread them in the bottom of the crockpot and refrigerate covered.

Next morning, we pull them out and let them get to room temp for an hour.

Then we get them going in the slow cooker on the high setting for a 2-3 hours.

We have to transport them to Grandmas, so we unplug and plug back in at Grandma’s house, topping with the marshmallows 30 minutes before serving.

If anything goes awry, we can throw some in a bowl and heat in the microwave quickly.

Not that I know from experience. 

Hope your family loves this dairy-free sweet potato casserole as much as we do!
