- 1 bunch broccoli (about 1 1/2 pounds)
- 1 cup whole milk
- 1/2 cup heavy cream
- 1 cup grated Parmigiano-Reggiano
- 2 large eggs
- 1 cup coarse fresh bread crumbs
- 1 tablespoon extra-virgin olive oil
- Preheat oven to 350°F with rack in upper third.
- Cut broccoli florets into 1-inch pieces, then peel large stems with a knife and cut into 1/2-inch-thick rounds. Cook broccoli in boiling salted water (2 tablespoon salt for 6 qt water) 5 minutes, then drain.
- Meanwhile, whisk together milk, cream, cheese, eggs, and 1/2 teaspoon each of salt and pepper.
- Put broccoli in a 2-quart shallow flameproof baking dish, then pour milk mixture over top. Toss bread crumbs with oil and a pinch each of salt and pepper, then sprinkle evenly over gratin.
- Bake until custard is set, about 30 minutes. Turn on broiler, then broil until bread crumbs are golden brown, 2 to 3 minutes. Let stand 5 minutes.
