Fresh Parsleyfor garnish (don't skip the parsley! This is a creamy and cheesy dish and the parsley adds the tiniest bit of brightness I think the casserole needs)
Preheat the oven to 350 degrees F and generously spray a 9×13” casserole dish with cooking spray.
Cook the spaghetti according to package instructions until al dente. Drain once it is cooked.
1 lb Spaghetti
In a large mixing bowl, whisk the cream cheese and butter together until smooth.
8 ounces Cream Cheese, ½ Cup Butter
Add the cooked chicken, cream of chicken soup, garlic, Italian dressing mix, chicken broth, half of the shredded cheese, and salt and pepper. Mix well until evenly combined.
3 Cups Cooked Chicken, 1 Can Cream of Chicken Soup, 3 Cloves Garlic, 0.7 ounce Good Seasons Dry Italian Dressing Mix, 1 Cup Chicken Broth, 2 ½ Cups Colby Jack Cheese, Salt and Pepper
Add the cooked spaghetti to the mixture and stir until the pasta is well coated. Pour into the prepared baking dish.
Top with the remaining shredded cheese. Spray foil with nonstick spray and gently cover the dish.
Bake in the preheated oven for about 25 minutes, removing the foil halfway through baking.
Remove from oven, and allow the casserole to cool for 5 minutes. Garnish with fresh parsley, and enjoy.
