The holidays aren’t the only time I think about sweet potato casserole…in truth, it’s one of my favorite side dishes and we make it regularly! Of course I had a come up with a way to cook this in the slow cooker!

One of the added benefits of making this crockpot sweet potato casserole is that it takes one of the bigger items out of the oven during the holidays. We have a wall oven and it’s a little on the smaller side. When it’s time to cook a bunch of things at once it can be tricky to time everything properly and get everything done!

The slow cooker can handle much more than just sides, of course, but this crockpot sweet potato casserole comes out so great that it just makes sense to cook it this way.

Here’s what you’ll need to make sweet potato casserole in the slow cooker:

This recipe calls for canned sweet potatoes, butter, brown sugar, and marshmallows. You can also spice this up a bit by adding some walnuts, nutmeg, cinnamon, or even a little pepper if you like to balance out the sweetness.

If you want to use fresh sweet potatoes you can do that but you’ll need to extend the cooking time. I would say double it at the very least and go from there. You can check them and see when they’re tender and then go onto the next steps!

How to make crockpot sweet potato casserole:

Spray the inside of a slow cooker with cooking spray. You can also use crockpot liners if you want to have even less cleanup!

Place sweet potatoes in a slow cooker and arrange butter on top of sweet potatoes. 

Sprinkle the brown sugar over sweet potatoes.

Cook on High, 3 to 3 1/2 hours.

Add marshmallows and cook until soft and somewhat puffy, about 15 minutes.

Be careful not to overcook the marshmallows or they will go from puffy and tasty to liquid in a hurry! If your crockpot runs hot be sure to keep an eye on them when you add them just before serving!

Is this a healthy side dish?

This is not what I’d consider a healthy side dish. It has quite a bit of sugar. That being said, sweet potatoes themselves are pretty healthy so you could easily cut back on the sugar or use natural alternatives like swerve brown sugar blends and take away the marshmallows.

When it comes to the holidays I don’t worry too much with making everything super healthy. We try to eat in moderation and just enjoy these treats once in a while!

Can I cut back on the marshmallows?

You can see that we really went for it with the marshmallows…they’re pretty much the best part in my opinion BUT you can definitely cut back the amount if you don’t want so much sugar, or so much gooey goodness on top.

This is not something we eat all the time so when I do make Crockpot sweet potato casserole I just go for it, you don’t have to do the same 🙂

Can I double this recipe?

Absolutely. Feel free to double or even triple the recipe. For this size crockpot you could double everything but the marshmallows and be set.

You’ll end up with a thicker layer of potatoes on the bottom and the marshmallows won’t cook up so far that they bubble over!

If you decide to double or triple the full recipe you’ll have to keep an eye on the marshmallows. When they start to puff up it might end up making a mess on the lid for you!
