A rich and delicious side dish, great for the holidays or anytime.
Added note: if you are using regular table salt instead of kosher salt please use half as much...
Preheat oven to 450 degrees. Use 1 tablespoon butter to butter a 9x9 or 9x13 baking dish.
2
Steam broccoli until crisp-tender, about 5 minutes.
3
Melt 3 tablespoons of the butter in a medium saucepan. Whisk in the flour until smooth. Cook, stirring, for 1 minute.
4
Add the milk, salt, and nutmeg and bring to a boil while stirring constantly. Lower heat and simmer, stirring occasionally, until the white sauce is thickened, about 10 minutes. Season with pepper.
5
Put the broccoli in the prepared baking dish. Sprinkle with half of the cheese and pour on the white sauce. Cover with the remaining cheese.
6
Melt the remaining 1 tablespoon butter in a small skillet. Add the bread crumbs and cook, stirring, until lightly browned.
7
Cover the gratin with the breadcrumbs. Bake at 450 for about 20 minutes, or until lightly browned and bubbly.
