    Not only is this recipe amazingly delicious but it is also very easy and quick to make. It has only a handful of main ingredients and takes approximately 30 minutes to cook. I am definitely making it for Thanksgiving this year! This sweet potato and kale gratin recipe has become a favorite Thanksgiving side dish but it also goes wonderfully as a side dish with other meats. I like to serve it with roasted chicken or ham.

    Tips for Making Sweet Potato and Kale Gratin

    • Use a [easyazon_link identifier=”B013JL2SVU” locale=”US” tag=”delimeethea05-20″]mandoline slicer[/easyazon_link] to slice the sweet potatoes into even slices. That guarantees that the sweet potato slices will cook evenly.
    • Prep the veggies ahead and keep them wrapped in ziplock bags, they will be good refrigerated for several days.
    • If you are serving a larger crowd, I would recommend to double the recipe and use a larger baking dish or to make two gratins. This recipe serves about 6 people.

    This gratin looks amazing! I love how easy it is to make.

    I’ve been on a sweet potato kick lately but I’ve never tried using it in a gratin. It sounds so delicious and looks creamy!


    Can I substitute 2% milk for the whole milk? And if that milk fat is needed what else should I use?


    5 stars
    This was very good!! I did add about a tablespoon of both parm and Greek yogurt cream cheese because I couldn’t resist. Will make this again!


    Could you replace the Kale with Spinach?


    Could I replace the milk with either coconut milk, or goat yogurt? We are out of milk..!

      Yes, you should be able top replace it with coconut milk. I haven’t tried to replace it with goat yogurt but it might work as far as texture goes if you thin it out a little bit, not sure how it will taste though.
