Instructions

Preheat Oven: Preheat your oven to 350ºF (175ºC) to prepare for baking the casserole evenly.
Mix Ingredients: In a large mixing bowl, combine the cooked chopped chicken, cooked spaghetti, unsalted cream of chicken soup, chicken broth, light sour cream, melted butter, cayenne pepper, dried parsley, salt, ground black pepper, Italian seasoning, and Parmesan cheese. Stir thoroughly to create a rich and creamy mixture.
Assemble Casserole: Lightly grease a 9×13-inch baking dish or two 9×9-inch dishes. Spread the chicken and pasta mixture evenly in the dish(es). Sprinkle the shredded cheddar cheese on top, followed by an even layer of Italian breadcrumbs to create a crispy topping.
Bake: Place the casserole uncovered in the preheated oven. Bake for 45 to 60 minutes until the casserole is bubbly, the cheese is melted, and the breadcrumbs turn golden brown.

Notes

For extra flavor, you can add sautéed onions or garlic into the sauce mixture before baking.
If you prefer, substitute rotisserie chicken with leftover cooked chicken or turkey.
The cayenne pepper adds just a subtle heat; adjust quantity according to taste.
Ensure spaghetti is well drained to prevent a watery casserole.
This casserole can be prepared a day ahead and refrigerated before baking.
