Cauliflower gratin is an elegant and simple cauliflower preparation, yet all there is to this flavorful and even healthy cauliflower gratin is cauliflower, a soufflé-like cheese sauce, and a crunchy Parmigiano Reggiano® cheese topping. This rich-tasting cauliflower gratin is also healthy because the Parmesan Cream Sauce is made with milk and broth rather than cream. You can prepare the cauliflower and make the cheese sauce in advance, and finish this cauliflower gratin recipe just before serving, making it ideal for a dinner party or a holiday dinner.
The light and airy cheese sauce in this cauliflower gratin has been known to make even people who don’t usually like cauliflower want to clean their plate, so this cauliflower gratin could become a regular at your table. If it does, serve cauliflower au gratin with roast chicken or grilled steak, a Sunday roast, or by itself for a delicious meatless main dish.
