Ingredients
  

Main Ingredients
  • 2 cups cooked chicken (shredded or diced)
  • 8 ounces spaghetti (uncooked)
  • 1 cup mushrooms (sliced, optional) You can omit if not desired.
  • 1 cup frozen peas
  • 1 cup heavy cream Can be substituted with a cream alternative.
  • 1 cup chicken broth
  • ½ cup grated Parmesan cheese Plus more for topping.
  • 1 tablespoon olive oil
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • ½ cup breadcrumbs For a crunchy topping.

Method
 

Preparation
  1. Start by boiling a large pot of water. Add the spaghetti and cook according to the package instructions until al dente. Drain and set aside.
  2. In a large skillet, heat olive oil over medium heat. If you’re using mushrooms, sauté them until they’re tender. Then, stir in the cooked chicken, garlic powder, onion powder, salt, and pepper to taste.
  3. Gradually add the chicken broth and heavy cream to the skillet, stirring to combine. Allow it to simmer for a few minutes until the sauce thickens slightly.
  4. In a large mixing bowl, combine the cooked spaghetti, chicken mixture, and frozen peas. Gently fold in the Parmesan cheese, ensuring everything is coated evenly.
  5. Pour the mixture into a greased casserole dish. Sprinkle breadcrumbs and additional Parmesan on top for a golden crust.
  6. Preheat your oven to 350°F (175°C). Bake the casserole for about 25-30 minutes, or until the top is golden and bubbly.
  7. Let it cool slightly before serving. This dish can be enjoyed hot, straight from the oven, or allowed to rest for a moment to get the flavors to meld.

Notes

Feel free to substitute cooked chicken with shredded turkey or canned chicken for a quicker version. Vegetarians can omit the chicken and add more vegetables like bell peppers or broccoli. Stir every so often to avoid overcooking the pasta.
