Ingredients
- 1 3-pound head cauliflower, cut into large florets
- 4 tablespoons (1/2 stick) unsalted butter, divided
- 3 tablespoons all-purpose flour
- 2 cups hot milk
- 1/2 teaspoon freshly ground black pepper
- 1/4 teaspoon grated nutmeg
- 3/4 cup grated Gruyère, divided
- 1/2 cup grated Parmesan
- 1/4 cup fresh bread crumbs
Directions
-
Preheat the oven to 375—F. Bring a large pot of salty water to boil. Boil the cauliflower florets until beginning to soften, but farm from tender, about 5 minutes.
-
In the meantime, melt 2 tablespoons of the butter in a sauce pan, then stir in the flour. Cook for 2-3 minutes, stirring often and removing any lumps. Add the warm milk (little by little at first), whisking constantly. Bring to a boil and cook until the mixture thickens, 1 to 3 minutes. Remove from the heat and add 1 teaspoon salt, the pepper, 1/2 cup of each cheese, and nutmeg. Stir well to incorporate.
-
Pour 1/3 of the sauce into an 8 × 11 inch baking dish, then add the cauliflower pieces. Cover with the remaining sauce, then top with a mixture of the bread crumbs and remaining Gruyère. Melt the remaining two tablespoons butter and drizzle over the top. Bake for 25-30 minutes, until the top is browned. Hit it with a broiler to really crisp it up.
