Traditionally, cauliflower cheese is boiled cauliflower served with a relatively light and basic cheese sauce. That is how cauliflower cheese has always been served by my mother. I prefer to use a few well-placed additions to “tart” things up a little. Serving this British classic with an oven-cooked topping of breadcrumbs, parmesan and thyme elevates it from a simple side dish. This is one recipe for cauliflower cheese that deserves to be eaten as a main with sides of its own.
