Add the bacon to non-stick frying pan and cook for 3 minutes. Add the butter and olive oil, onion, garlic, sea salt and black pepper and sauté for 3 more minutes until the onions are soft. Remove from the pan and set side.
Add the heavy cream, cream cheese, mozzarella,1/4 cup Parmesan cheese, mustard, 2 tbsp water and seasoning into the pan. Mix until combined using a spatula or hand balloon whisk. Reduce the heat to medium/ low and simmer until the sauce thickens. Once thick, stir in the bacon and onion. Taste and adjust the seasoning to taste.
Slice the cauliflower into 1/2 cm thick slices. I used a mandoline to get them nice and even and baby cauliflowers but you can use a larger one and just break into large florets and slice. You can use the ends too so as not to waste them.
Grease an oven proof cast iron pan or gratin dish with a little butte (mine was 10 inch x 2 inches). Add a thin layer of sauce on the bottom, followed by some cauliflower slices, more sauce, another layer of cauliflower and top with a final layer of sauce and sprinkle the remaining parmesan over the top of the dish. Depending on the size of your dish you may prefer to have 1 or 2 layers of cauliflow-er and 2 or 3 layers of sauce.
Cover with foil and bake for 20 minutes. Uncover and cook for a further 15 minutes or until golden on top and the cauliflower is tender. Option to top with fresh thyme for prettiness.
