The BEST way to eat cauliflower for Thanksgiving, Christmas and beyond is in a Cheesy Cauliflower Gratin! Topped with bacon, this side dish tastes amazing!
The holidays are coming. I keep trying to forget it but it doesn’t change the fact that Thanksgiving is next week and will be quickly followed by Christmas. During the holidays, I am totally a side dish and dessert person!

Sure, I like the turkey but the sides, like stuffing {or this one} and vegetables {green or starchy} are where I really focus. To add a little variety to our side dish menu this year, I’m going to make a Cheesy Cauliflower Gratin.
Since focusing more on the paleo way of eating, cauliflower has become a staple in our house. Of course, this cauliflower au gratin version is filled with a gooey cheese sauce so it is far from paleo. BUT, it does have a healthy vegetable tucked in there so it is all good!

I tried this cauliflower side dish with a mixture of gruyere and gouda cheese in place of the pepper jack and it was so good too. So, if you prefer to skip the little bit of heat that the pepper jack cheese gives, the blend would be a good substitute.
