Main Ingredients

  • 8 oz linguine or spaghetti Cooked according to package instructions and drained.
  • 2 cups cooked chicken Shredded or cubed.
  • 8 oz mushrooms Sliced.
  • 1/4 cup butter For sautéing.
  • 1/4 cup all-purpose flour To thicken the sauce.
  • 2 cups chicken broth Creates a rich flavor base.
  • 1 cup heavy cream This adds the creamy texture we love.
  • 1 cup grated Parmesan cheese A lovely touch of nutty flavor.
  • 1/2 tsp garlic powder For a hint of aromatic essence.
  • 1/2 tsp black pepper Just enough to season.
  • 1/2 cup breadcrumbs For topping.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C).
  • In a large pot, cook the linguine according to the package instructions. Drain and set aside.
  • In a skillet, melt the butter over medium heat. Add the sliced mushrooms and sauté until tender (about 4–5 minutes).
  • Sprinkle the flour over the mushrooms and stir to combine. Gradually whisk in the chicken broth and cream, allowing it to thicken while stirring.
  • Once thickened, stir in the cooked chicken, garlic powder, black pepper, and half of the Parmesan cheese. Mix well.
  • In a large bowl, combine the cooked pasta with the sauce mixture until evenly coated.
  • Pour the mixture into a greased 9x13 inch baking dish.
  • Sprinkle breadcrumbs and the remaining Parmesan cheese on top, then bake for 20–25 minutes, or until bubbly and golden.

Notes

You can swap chicken for turkey or a plant-based option. This dish can be prepared a day in advance. Avoid overcooking the pasta, as it will continue to cook in the oven.
