Wintertime is comfort food season. I love making big bowls of pasta, pots of chili, soups and stews. Boston winters are pretty cold, so anything that warms me up from the inside out is my ideal winter food. And this Gluten-Free Baked Cauliflower Gratin is basically a warm, cheesy baked cauliflower dish and its the ULTIMATE wintertime comfort food.
Creamy sauce for the gratin 
The assembled cauliflower gratin ready for the oven
Cauliflower is one of my favorite vegetables to keep on hand. Its delicious roasted, sautéd, grilled, pureed, and riced. You name it, cauliflower can do it. It also stays fresh in the refrigerator for well over a week, which means I really can always have it on hand without worrying about it going bad.
What is Gratin
And now we can definitively add gratin to the list of cooking techniques that cauliflower is amazing for because this Baked Cauliflower Gratin is INCREDIBLE. The term gratin technically only refers to the browned bread crumb crust of this dish. But, when I think of gratin I also think of a creamy cheesy sauce in addition to a brown breadcrumb crust. So this dish is really like a cheesy baked cauliflower.
Making a Cashew Cream Sauce For Baked Cauliflower Gratin
The creamy sauce for this Gluten-Free Baked Cauliflower Gratin a cashew cream sauce. To achieve a creamy cashew sauce, its imperative to first soak the cashews. Soaking helps soften the cashews so the blender can blend them into a completely smooth sauce. I like to turn my tea kettle on and pour boiling water over the cashews and allow them to soak for 30 minutes to an hour.
Once the cashews are soaked, combine all the sauce ingredients in a blender and blend until the sauce is smooth. It creates and incredibly creamy and cheesy sauce for the Gluten-Free Baked Cauliflower Gratin. Which makes this dish like a cheesy baked cauliflower.
I have a high speed blender, which I realize not everyone has. This recipe will also work in a magic bullet style blender, but it may not blend completely smooth in a regular large blender. In my experience, the smaller, single serving magic bullet blenders do a much better job that the standard large blenders.
Finding Gluten-Free Panko
I used gluten-free panko bread crumbs as the topping for this Baked Cauliflower Gratin. Panko bread crumbs are a Japanese variety of bread crumbs that are lighter texture and larger in size than standard bread crumbs. While they are not traditionally gluten-free, there are a wide variety of gluten free panko bread crumbs on the market. My favorite are Ian’s Original Panko Bread Crumbs, and Kikkoman Gluten-Free Panko. But, there are many brands to choose from so use what is accessible. OR if you don’t need to avoid gluten, go with the traditional panko!
This Gluten-Free Creamy Baked Cauliflower Gratin is incredibly creamy, warm and comforting. Its the perfect special side dish to any winter meal.
