A savory sweet potato side dish is perfect for holidays or anytime!
I am not gonna lie — I am all about a sweet potato casserole with marshmallows on top. It’s the perfect holiday side dish to balance out all the savory, salty dishes.

But there are definitely better uses of sweet potatoes, and I sometimes feel like people don’t eat them at any other time than the holidays. Which is a shame because they’re healthy and delicious.
So I spend a lot of time during the last few months making different holiday dishes, from cookies to pies, to cocktails, and even some vegetarian mains so that everyone can enjoy a holiday meal.

I also feel like you need some dishes that are at least somewhat healthy. You can’t overdo it — no one is going to load up on salad when there’s mashed potatoes and stuffing. But you certainly can make sides that are healthy and tasty, yet still somewhat indulgent.
This savory sweet potato side dish is a good example of that. It’s got lots of good things in it, but a crunchy, cheesy top that fits right into your holiday table. Or any table. I sometimes make this and eat it for dinner on its own.
The key to getting tender, melt in your mouth potatoes is slicing them really thin, while keeping them the same thickness. You can do this with a really sharp knife, but if you have a mandolin slicer (this is my favorite one, and I’ve used a lot of them!), that will make it much easier. If your knife skills aren’t up to par, definitely use a mandolin. Uneven slices lead to mushiness in some parts and raw potatoes in others.
You can use spinach or any other green vegetable in place of the kale. I like kale this time of year because it’s hearty, wintery, and I love kale in general. But use what you like.
