Step‑by‑Step Instructions for Cheesy Chicken Spaghetti Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures your Cheesy Chicken Spaghetti Casserole will bake evenly and become perfectly bubbly and golden on top. While the oven heats up, you can focus on preparing the filling, creating that delightful mix of flavors.

Step 2: Mix the Ingredients
In a large mixing bowl, combine your shredded chicken, cooked spaghetti, cream of chicken soup, and milk. Stir in cream cheese until fully integrated, creating a creamy base. Sprinkle in your favorite seasonings like garlic powder and onion powder for that extra flavor punch. Mix well until everything is evenly coated, preparing the luscious filling for your casserole.

Step 3: Assemble the Casserole
Grease a 9×13 inch casserole dish with cooking spray or butter to prevent sticking. Pour the chicken and spaghetti mixture into the prepared dish, spreading it out evenly. Once the mixture is smoothed into the dish, sprinkle a generous layer of cheddar, mozzarella, and Parmesan cheese on top, forming a rich, cheesy blanket that will melt beautifully.

Step 4: Bake Until Golden
Place your assembled Cheesy Chicken Spaghetti Casserole in the preheated oven. Bake for 30-35 minutes, or until the cheese is bubbly and golden brown. Keep an eye on it during the last few minutes to achieve that perfect golden color. This step is key to achieving the luscious, gooey topping that defines this comfort dish.

Step 5: Cool Before Serving
Once baked, carefully remove the casserole from the oven and let it cool for about 5-10 minutes. This resting time allows the Cheesy Chicken Spaghetti Casserole to set, making it easier to serve. As you wait, enjoy the comforting aromas wafting through your kitchen—your family will be eager for a taste!

Cheesy Chicken Spaghetti Casserole Recipe FAQs

Very! If your casserole appears dry, simply add a splash of milk or a handful of cheese before serving. Mix gently, and then pop it back in the oven for 5-10 minutes to help it become creamy again.
