Ingredients
2 tablespoons extra-virgin olive oil
2 pounds skinless cod fillets, about 1 inch thick
2 tablespoons fresh lemon juice, plus 2 tablespoons finely grated lemon zest Kosher salt
Pepper
7 tablespoons unsalted butter
1 cup plain dry breadcrumbs
1/4 cup freshly grated Parmigiano-Reggiano cheese
1/4 cup chopped parsley
2 tablespoons chopped chives
2 teaspoons smoked sea salt (optional)
1/4 teaspoon crushed red pepper
2 1/2 tablespoons all-purpose flour
1 cup heavy cream
3 ounces Gruyère cheese, shredded (scant 1 cup)
4 ounces cream cheese, softened
Pinch of smoked paprika
10 ounces frozen artichoke heart quarters, thawed and patted dry
Crudités or potato chips, for serving

Method

1.Preheat the oven to 375°. Brush a large baking dish with 1 tablespoon of the olive oil. Add the fish and top with the lemon juice, 1 tablespoon of lemon zest and the remaining 1 tablespoon of olive oil; season with kosher salt and pepper. Bake for about 20 minutes, until the fish just flakes; let cool. Leave the oven on. Once the fish is cool, cut into small pieces.

2.Meanwhile, in a medium saucepan, melt 4 tablespoons of the butter over moderate heat. Stir in the breadcrumbs, Parmigiano-Reggiano, parsley, chives, smoked sea salt, crushed red pepper and the remaining 1 tablespoon of lemon zest.

3.In a medium saucepan, melt the remaining 3 tablespoons of butter over moderate heat. Add the flour and cook, whisking, for about 2 minutes. Add the cream and cook, whisking constantly, until thickened, about 4 minutes. Add the Gruyère, cream cheese and paprika and cook, stirring, until the cheese is just melted, about 2 minutes. Fold in the artichokes and fish and season with kosher salt and pepper.

4.Spread the fish mixture in a 10-inch glass or ceramic pie plate. Sprinkle the breadcrumbs on top. Bake for about 20 minutes, or until bubbling at the edge and the top is golden. Serve warm with crudités or potato chips.
