Gruyere Sweet Potato Gratin

this is a new family favorite holiday side dish that i am so excited to share with you!


so, i’m slowly turning my family around to my ever-changing food experiments.


they are my willing guinea pigs and give honest feedback about what they like and don’t like. especially during the holidays.


i’m allowed to bring one “crazy” side dish that crashes the party of traditional family holiday foods.


this is the dish i brought to thanksgiving last year.



and they liked it so much that my parents made it with christmas dinner!







so i’ve patiently waited to share it with you at a seasonally appropriate time!



the crowd pleasing and unexpected combination of


  • the fresh thyme
  • with the nuttiness of the gruyere,
  • and the earthiness of the roasted garlic and sweet potato


all come together for a subtly complex side dish that perfectly pairs with pork, chicken or turkey and all the fixin’s.



i replaced the heavy cream from the original recipe with greek yogurt because of family dietary needs. try it both ways and let me know which you like better.




  • what’s your favorite holiday dish from childhood and/or now?



  • do you have a relative with out of the family-box cooking tendencies?
    • if so, have you shared this blog with them? please?
    • if not, does that make you that person? i’m asking for a friend.
