You’ll get all the flavor of traditional Thanksgiving stuffing in this Roasted Cauliflower Mushroom Stuffing but it is grain free, gluten free, vegan and Whole30 compliant! Roasted cauliflower, mushrooms and walnuts form the base of this delicious holiday side dish.
I love Thanksgiving. It’s an opportunity to celebrate food, friends and family! It warms my heart to remember spending hours in the kitchen with my mother preparing the feast. We loved talking and laughing together.
My mother made the best stuffing in the world. The base was bread and it had lots and lots of butter, yum! It was my favorite Thanksgiving side dish.
But over the years as my diet has changed. Now I prefer a healthier version of stuffing that’s gluten free but still full of the traditional flavors. After many tries I came up with this delicious version with a roasted cauliflower base mixed with mushroom, leeks, celery, walnuts, garlic, parsley, sage and thyme. I love it because it’s simple to prepare and the ingredients are easy to find.
I use walnuts but it’s even more spectacular with roasted chestnuts.
You’re going to love adding this seriously delicious, healthy, and festive side dish to this year’s holiday table! Preheat your oven and grab your ingredients because it’s time to start – let’s go!
The first step is roasting cauliflower florets until lightly brown.
While the cauliflower is roasting, saute the leeks, celery, garlic and mushrooms in olive oil. Grass fed butter or ghee is also good.
Put the walnuts, parsley, sage and thyme into a food processor and just pulse enough to chop. I like that you don’t have to chop it by hand.
Once the cauliflower is done, add half of it to the food processor and pulse until you get a crumble like consistency. This makes a nice base.
The next step is to add the walnut/cauliflower mixture to the pan with the mushrooms and the rest of the roasted cauliflower. The combination of whole and chopped cauliflower creates a good texture. I add an egg to bind it together but it’s not necessary if you don’t eat eggs.
Transfer the mixture to a 2 quart baking dish.
Roast in the oven for 30-35 minutes to get it nicely brown on top.
This stuffing reheats very well in the oven too – so it’s no problem to make it ahead of time Simply cover it with aluminum foil and reheat in a 400° oven until heated through.
