Cauliflower Au Gratin

Cauliflower Au Gratin
Something wonderful happens to cauliflower when combined with bechamel and lots of cheese...I can't fully describe how velvety smooth and creamy this is. The cheese sauce is absolute heaven, the perfect complement to cauliflower. The topping adds lots of flavor and a little crunch. A definite comfort food!

Ingredients of Cauliflower Au Gratin

-- Bechamel --
* 1/4 cup (1/2 stick) unsalted butter
* 1/4 cup unbleached all-purpose flour
* 2 cups milk or half-and-half, scalded
* 1/4 teaspoon salt (for scalded milk)
* 1 small bay leaf, broken in two
* Salt and fresh ground white pepper
* 1 pinch nutmeg, freshly ground

-- Gratin --
* 2 tablespoons salt (for pre-cooking cauliflower)
* 1 teaspoon white wine vinegar (for pre-cooking cauliflower)
* 1 head cauliflower (about 11/2 pounds)
* 2 cups bechamel sauce
* 1 cup (about 3 oz) Swiss Gruyere cheese, finely grated
* Salt and fresh ground white pepper

-- Basil Crumb Topping --
* 1/2 cup (about 1 oz) Parmesan cheese, or addition Gruyere, finely grated
* 1/2 cup panko (Japanese bread crumbs) or dried bread crumb
* 1 tablespoon fresh basil or flat-leaf (Italian) parsley, chopped
* 2 tablespoons olive oil

Preparation of Cauliflower Au Gratin
To make Bechamel: In a heavy-bottomed 2-quart saucepan, melt butter over medium-low heat. When butter starts to foam, add flour and mix using a wooden spoon to create a smooth, loose paste. Cook, stirring constantly, allowing butter and flour to froth together until the mixture turns a light, golden sandy color, about 4 to 5 minutes. Remove pan from heat and let stand.

Meanwhile, combine milk and 1/4 teaspoon salt in a medium saucepan, scald milk (heating it until just below boiling point). Return saucepan with roux to medium-low heat. Add half of the hot milk to the roux, whisking vigorously to thoroughly blend and prevent lumps, and bring to a boil over medium-high heat. When a boil is reached and sauce is smooth, add the remaining milk and bay leaf, reduce heat to low, and simmer, whisking occasionally, until the sauce is smooth and thickened, about 10 to 12 minutes. Strain sauce through fine-mesh strainer. Season with salt, white pepper and nutmeg to taste, and set aside until ready to use. (Makes about 2 cups.)

To make Gratin: Preheat oven to 375 degrees F. Bring 3 quarts of water to a rapid boil with 2 tablespoons of salt and vinegar. (The acid in vinegar helps keep cauliflower white.) Cut cauliflower into 1 1/2-inch wide florets. Boil florets until just tender, about 4 to 5 minutes, drain well without rinsing, pat dry, and season with salt to taste.

Arrange the cauliflower, florets-side up, in a buttered, medium (about 8-cup) oval gratin dish or baking dish just large enough to hold cauliflour in a single layer. If the bechamel sauce is cold, bring it to a simmer on the stove while whisking. Gradually stir Gruyere cheese into the hot bechamel and adjust seasoning with salt and pepper, to taste. In a small bowl, combine the parmesan, bread crumbs and basil, and mix with olive oil, to coat evenly. Spoon bechamel over the cauliflower and sprinkle everything, evenly, with crumb topping.

Bake in center of oven until gratin is bubbling and lightly browned on top, about 30 to 35 minutes. Let rest for 5 to 10 minutes before serving. Serve hot, or at room temperature.
