Preheat Oven to 425°F.
Cut cauliflower into florets and place in a microwave safe bowl. Microwave for 5 minutes to steam . Do not add water!
Place steamed cauliflower in a colander and allow to drain.
While the cauliflower is cooling, start preparing the béchamel sauce.
In a saucepan over medium heat add butter.
Once butter is melted, add water and heavy whipping cream.
Whisk in xanthan gum and slowly add in grated cheese while continuing to whisk.
Once sauce thickens and is heated through, set aside. About 2-3 minutes.
Pat dry the steamed cauliflower to remove excess liquid.
In an oven safe baking dish, add half the sauce to the bottom of the dish.
Add the cauliflower to the baking dish; sprinkle with salt and pepper.
Pour the remainder of the béchamel sauce on top of the cauliflower.
Sprinkle 60 grams of the gruyère cheese on top of the cauliflower, followed by the crushed pork rinds.
Drizzle 1 tbsp of olive oil on top of the dish.
Bake in a preheated oven for 30 minutes.
Top with dried parsley or chives.
Enjoy!
