If you make an oil- or butter-based sauce with your spices, paint the outside of the whole cauliflower with some of it, then turn the veg upside down and introduce the rest of the sauce into the cauliflower's insides, between the stalks, and bake whole at slightly lower temp, say 400F, for a slightly longer time, maybe up to 45mn. Cut into halves if small, quarters for large, to serve. A total fave.

I use crumpled tin foil, or a couple of toothpicks, to keep the cauliflower nicely upside-down.

I strongly prefer cooked to raw cauliflower, but I think that is a minority view...
