½ (16-ounce) box linguine, cooked according to package directions
3 cups chopped cooked chicken
1 cup Italian-style panko (Japanese bread crumbs)
1 tablespoon unsalted butter, melted
Garnish: chopped fresh rosemary, ground black pepper
Instructions
Spray a 13×9-inch baking dish with cooking spray.
In a large Dutch oven, heat butter over medium heat. Add mushrooms, shallot, and garlic; cook, stirring frequently, until softened, 3 to 4 minutes. Add flour; cook for 2 minutes, stirring constantly. Stir in broth, cream, wine, rosemary, salt, pepper, and nutmeg (if using); bring to a boil. Reduce heat to medium; cook, stirring frequently, until thickened, 2 to 4 minutes.
Remove from heat; stir in 1½ cups fontina and ½ cup Pecorino Romano until melted and smooth. Stir in pasta and chicken; transfer to prepared pan.
In a small bowl, stir together bread crumbs, melted butter, remaining ½ cup fontina, and remaining ¼ cup Pecorino Romano. Sprinkle bread crumbs mixture over pasta mixture.
Preheat oven to 350°. Bake until topping is golden brown and filling is bubbly, about 25 minutes, loosely covering with foil during last 5 minutes of baking to prevent excess browning, if necessary. Let stand for 10 minutes before serving. Garnish with rosemary and pepper, if desired.
