Yield 8 servings

Number Of Ingredients 24

For the Caramelized Shallots:
1 tablespoon unsalted butter
6 - 8 shallots thinly sliced lengthwise
1 teaspoon sugar
Kosher salt
Freshly ground pepper
For the Gratin:
1 tablespoon unsalted butter
Kosher salt
2 pounds brussels sprouts, trimmed and halved
2 tablespoons flour
8 oz. Gruyere, grated
1/2 oz. Parmesan, grated
1 teaspoon lemon zest
3/4 teaspoon freshly ground black pepper
1 cup heavy cream
1 cup caramelized shallots
For the Topping:
3 cups coarse fresh breadcrumbs (used a baguette)
3 tablespoons unsalted butter, melted
1 1/2 teaspoons lemon zest
1/2 teaspoon kosher salt
1/2 teaspoon freshly ground pepper
2 tablespoons minced fresh flat leaf parsley

Steps:

For the Caramelized Shallots: Warm the butter in a medium, heavy bottom saucepan over medium-low heat. Add sliced shallots and season with sugar, a pinch of salt and a few turns of freshly ground pepper. Cook shallots until caramelized (light brown and soft), stirring frequently. This should take 15 - 20 minutes. Reserve 1 cup of caramelized shallots for the gratin. Refrigerate any leftovers. For the Gratin & Topping: Preheat oven to 375. Grease a 9x13 baking dish. Set aside. Prepare an ice bath. Also set aside. Fill a large pot 3/4 of the way with water and bring to a boil over high heat. Once boiling add a handful of salt. Drop in the brussels sprouts and cook until just tender (about 5 minutes). Using slotted spoon, transfer to ice bath. Drain and gently dry with paper towels. In a large bowl, stir together the flour, Gruyere, Parmesan, lemon zest, 2 teaspoons of kosher salt and the freshly ground pepper. Add the cream, brussels sprouts and caramelized shallots, stirring to combine. Transfer the mixture to the prepared baking dish and smooth out the top. To make the topping, add bread crumbs, melted butter, lemon zest, salt, pepper and parsley to a medium bowl, stirring to combine. Sprinkle the topping evenly over the gratin. Bake until the bread crumbs are golden brown (30 - 35 minutes). Let the gratin rest for 10 - 15 minutes before serving.
