Free up space in your oven this holiday season by making this recipe for Crock-Pot Sweet Potato Casserole! Featuring melty marshmallows on top!

Slow Cooker Sweet Potato Casserole
One of my favorite ways to make the holiday season just a little bit simpler is to use my slow cooker whenever possible when cooking for the big holiday meals like Thanksgiving and Christmas.
In fact, I recently was a guest on the Little House Living podcast talking about Simplifying Your Holidays With Your Crock Pot. Head on over and listen if you are looking for some great tips!
Cooking this lovely and simple sweet potato casserole in your slow cooker takes some of the pressure off you in the timing of the holiday feast side dishes and playing the oven rotation game.
Instead of rushing to get the side dishes prepped and cooking in the oven and timed just right for everything to be ready in time for dinner you can cut up the sweet potatoes, toss them in the butter/sugar/spice mixture and set them aside to cook in the slow cooker for hours.
Then right before serving toss on some mini marshmallows and let them melt on top of the sweet potatoes for just a few minutes.
Smart Tip: Short On Counter Space?
If your kitchen is small or you are running out of counter space on Thanksgiving or Christmas. Grab your slow cooker and plug it in another room.
For instance, last Thanksgiving I cleaned everything off my desk counter in the home office and set up 5 different slow cookers to cook away out of the kitchen and out of my way. Because it was such an awesome idea, I plan on doing the same this year!

Frequently Asked Questions
You can peel and cut the sweet potatoes up to 4 days ahead of time. Wash the sweet potatoes, peel them with a vegetable peeler, cut them into 1 inch chunks and place the chunks into a gallon sized zippered food storage bag or airtight container. Place the cut sweet potatoes in the refrigerator for up to 4 days.
This sweet potato casserole can be made up to three days ahead of time except for the marshmallow topping. To make ahead of time prepare the sweet potatoes and cook them in the slow cooker. Let the cooked sweet potatoes cool for about 30 minutes, then wrap the ceramic insert with foil or plastic wrap and pop into the refrigerator for up to 3 days.
On the day you are ready to serve the sweet potatoes, take the slow cooker insert out of the refrigerator and unwrap it. Place the insert into the base of the slow cooker and turn the slow cooker to the LOW heat setting (do not use the HIGH setting as the quick change in temperature can crack the slow cooker insert) and heat for 1 to 2 hours or until the potatoes are hot. Top with the miniature marshmallows and allow them to melt for 5 to 10 minutes.
If you prefer the marshmallows on top of your sweet potato casserole to be lightly browned and toasted you can pop the ceramic slow cooker insert (not the cooking base) under the broiler in your oven for 2 to 3 minutes until the marshmallows are toasted to your liking. Additionally, you could also use a small kitchen torch to toast the marshmallows.
