Cauliflower Gratin

Here is the recipe for Cauliflower Gratin, a classic Italian side dish.

Cauliflower gratin is an oven-baked cheesy and creamy side dish, easy and quick to make.

A delight!

Cauliflower is, unfortunately, one of those vegetables that not everyone likes, especially children, but if we bake it in a rich cheesy sauce and top it with an extra sprinkling of Mozzarella and Parmesan cheese it becomes a truly irresistible dish for the whole family.

In Italy, we use to serve the cauliflower au gratin as a side dish of meat or fish dishes, but it is also excellent as a tasty and fragrant appetizer.

In short cauliflower gratin is really a jolly dish that can be served in many ways and occasions.

Personally, for the preparation of this recipe, I use gorgonzola cheese with its strong taste, but if you prefer a less decisive taste, you can also use a cheese with a lighter flavor, such as Fontina, Gruyère, Cheddar or smoked Scamorza cheese.

This depends on your tastes.

How to choose a cauliflower:

A good cauliflower should be firm and tightly closed, the head should be white, with no dark “sunburned” spots.

Reject any heads that show signs of softness, that’s the start of spoilage.

How to prepare cauliflower:

Remove the leaves from the cauliflower. Cut around the underside of the head removing the core.

Detach the florets where they join at the center. Separate the florets by cutting through the base to make smaller florets.

How to cook cauliflower for gratin:

Before baking in the oven, cook the cauliflower in boiling water and then drain it. But I suggest steaming it to keep intact all the nutritional properties of this vegetable intact

For medium-sized florets, check the cooking after 7 minutes. If they still seem too hard, cover the steamer and continue to cook.

Usually, it will take 7 to 10 minutes for the cauliflower to cook through.

Large florets can take up to 13 minutes.
