"Be sure to use freshly grated nutmeg. Combined with the fresh thyme and mushrooms, it creates such an amazing aroma that your guests will[ be drooling before you pull the casserole out of the oven."]

6 servings

  • Kosher salt
  • 6 tablespoons unsalted butter, plus more for the baking dish
  • 8 ounces elbow macaroni
  • 8 ounces cremini mushrooms, thickly sliced
  • Freshly ground pepper
  • 1 bunch scallions (white and light green parts only), chopped (about 1 cup)
  • 2 teaspoons chopped fresh thyme
  • 1 clove garlic, finely chopped
  • 5 tablespoons all-purpose flour
  • 2 tablespoons dry white wine
  • 3 cups low-sodium chicken broth
  • 1 cup half-and-half
  • Generous pinch of freshly grated nutmeg
  • 3 cups chopped rotisserie chicken, skin and bones removed (or use leftover cooked chicken or turkey)
  • 1 1/2 cups frozen peas and carrots, thawed (8 ounces)
  • 1/4 cup chopped fresh Italian parsley
  • 4 ounces cream cheese, cut into chunks and softened
  • 1/4 cup breadcrumbs
  • 1/4 cup grated parmesan cheese
  • Bring a large pot of salted water to a boil for the pasta. Preheat the oven to 400 degrees F. Butter a 3-quart baking dish. When the water is boiling, add the elbow macaroni and cook until very al dente, several minutes shy of the package cooking time. Drain, rinse and pat dry, then put in a large bowl.

  • In a large saucepan over medium heat, melt 4 tablespoons of the butter. Add the mushrooms and season with salt and pepper. Cook until the mushrooms have given up their liquid. Increase the heat to boil away any excess liquid, about 5 minutes. Add the scallions, thyme and garlic and cook until the scallions are wilted, about 3 minutes.

  • Sprinkle the vegetables with the flour and cook, stirring, until lightly browned, about 1 minute. Add the wine and cook until just absorbed. Pour in the chicken broth and half-and-half. Bring to a simmer and season with salt, pepper and the nutmeg. Simmer until the sauce is thickened and has lost the raw flour taste, about 7 minutes. Stir in the chicken, peas and carrots, and parsley and simmer just to heat the chicken through. Off the heat, whisk in the cream cheese until smooth.

  • Pour the chicken and sauce into the bowl with the macaroni and toss well. Spread in the prepared baking dish. In a small bowl, toss together the breadcrumbs and parmesan. Sprinkle the breadcrumb mixture over the top of the baking dish. Dot the top with the remaining 2 tablespoons butter, cut into small pieces. Bake until the casserole is very bubbly and the top is crispy and golden brown, about 25 minutes. Let sit 10 minutes before serving.
