A sweet potato casserole is a wonderful addition to any meal. Using roasted sweet potatoes this easy recipe uses simple ingredients for a great savory side dish.
I am always on the look out for sweet potato recipes that aren’t all that sweet. This is a take on my cinnamon and sage roasted sweet potatoes. Made with just a few additional ingredients they transform the sweet potatoes into a dish that will disappear very quickly. Although these made a wonderful Thanksgiving side dish I find that they are great all year round!
In this recipe
One of my favorite things about this recipe is that there really isn’t a lot in it. With just a few ingredients you can make a great side dish and on top of that if you have an immersion blender this is a great time to use it. A food processor works well also. There is a little maple syrup in this recipe but not enough to add a lot of sweetness to the dish. Like vanilla in other dishes it is really there to help enhance the other flavors.
Time to roast
By cutting them in half lengthwise you will drastically reduce the time they need to roast in the oven. Once the potatoes cook the skin will come right off. Be sure to choose sweet potatoes that are roughly the same size so they will all finish cooking at the same time. However depending on the size of the sweet potatoes (the ones in the photo were about a pound each) you might find that they will cook in a little as 15 minutes or up to 30 minutes. A great way to tell they are done is that the skin will be wrinkly and a fork on knife passes through easily.
Crispy sage butter
One of the best things about this recipe is the sage infused butter. You will get this by cooking the sage until it is nice and crispy in the butter. The good thing is that you can just add the leaves in whole. However you don’t want to cook it on high heat to keep the butter from browning and scorching too quickly. Once you add the shallots you will cook until they become translucent and soft.
Topping on sweet potato casserole?
I have always been on those that really don’t want a crunchy topping on my sweet potatoes. I don’t know why but I like them them without. However if you would like to add one by all means please do. I have a few recommendations for you that should compliment the potatoes well.
- Toasted or candied pecans.
- Breadcrumbs toasted in additional sage butter.
- Additional parmesan cheese
- Now just go with me on this one but bacon bits. Trust me you will thank me later. You will want to add these after it is done cooking so they don’t make the topping greasy.
- A combination of all of the above. If you want to keep it savory then just toast the pecans but just a little sweetness is also good.

- If using a food processor this might need to be done in batches but add the potatoes, half of the cream, and the sage mixture and blend until they have been pureed. Pour that mixture into the bowl. Add the remaining sweet potatoes, cream, thyme, salt, pepper, and maple syrup to the food processor and blend until pureed. Pour that into the mixing bowl and stir in the parmesan cheese.
