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 temperature ensures even baking and helps develop that lovely golden top your Cheesy Chicken Spaghetti Casserole will boast. While the oven heats up, gather your ingredients for an organized cooking experience.

Step 2: Cook the Pasta
In a large pot of boiling salted water, cook the spaghetti according to the package instructions until it reaches an al dente texture, usually around 8-10 minutes. Once cooked, drain the pasta well and set it aside. This will serve as the hearty base of your casserole, ready to soak up all the creamy goodness!

Step 3: Prepare the Sauce
In a medium saucepan, combine your shredded chicken, cooked spaghetti, and creamy sauce ingredients, which can include cheese, cream, and seasonings. Stir everything together over low to medium heat for about 5 minutes until it’s heated through and well blended. This mixture should be smooth, showcasing the luscious flavors of your Cheesy Chicken Spaghetti Casserole.

Step 4: Assemble the Casserole
Take a greased 9×13 inch baking dish and pour the chicken and spaghetti mixture into it, spreading it evenly. To enhance the flavors and textures, generously sprinkle shredded cheddar and grated Parmesan cheese on top. These cheeses will create a beautiful, melty crust as they bake, adding to the rich comfort of the dish.

Step 5: Bake to Perfection
Carefully place the assembled casserole in your preheated oven. Bake for 25-30 minutes, or until you see the edges bubbling and the top has turned a delightful golden color. The aroma wafting through your kitchen will be irresistible, signaling that your Cheesy Chicken Spaghetti Casserole is nearing completion.

Step 6: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for about 5-10 minutes. This resting time lets the layers set, making it easier to slice and serve. When you’re ready, dig into this comforting masterpiece and savor every cheesy, delicious bite!
