Step 1

Heat the oven to 425°F (220°C). Put the Brussels sprouts in a 9 x 13-inch (23 x 33-cm) ceramic or metal baking dish, and toss with 2 tablespoons of the melted butter, ¾ teaspoon salt, and ¼ teaspoon pepper. Spread the sprouts evenly in the dish and roast, tossing once halfway through, until tender and browned in spots, 25 to 30 minutes.

Step 2

While the sprouts roast, place the bread crumbs in a medium bowl. Pour the remaining tablespoon of melted butter over the crumbs and sprinkle with ⅛ teaspoon salt. Mix in the Gruyère. Set aside.

Step 3

When the sprouts are tender and browned, pour the cream evenly over the sprouts and sprinkle with ¼ teaspoon salt. Continue baking until the cream has thickened to a saucy consistency, about 10 minutes. Remove the pan from the oven. Set the oven to broil and position a rack to 6 inches below the broiler. Sprinkle on the bread crumb mixture. Broil the gratin until the crust is golden brown, 3 to 5 minutes (keep a close eye on it so it doesn't burn).
