Step‑by‑Step Instructions for Cheesy Chicken Spaghetti Casserole
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) while you grease a large casserole dish with cooking spray or a touch of butter. This step is essential to ensure your Spicy Southern Cheesy Chicken Spaghetti Casserole bakes evenly and doesn't stick to the pan, giving you a golden, crispy edge when it's done.
Step 2: Cook the Chicken
In a large pot over medium heat, place the boneless, skinless chicken breasts and cook for about 6–7 minutes per side. You'll know the chicken is done when it turns golden brown and is no longer pink in the center. Once cooked, remove the chicken and let it cool slightly before shredding it into bite-sized pieces for your casserole.
Step 3: Boil the Spaghetti
Bring a large pot of salted water to a boil on high heat. Add the spaghetti and cook for 8–10 minutes, stirring occasionally until it reaches an al dente texture. Drain the spaghetti thoroughly in a colander, allowing excess water to escape, and set it aside, ready to combine with the other ingredients for the Cheesy Chicken Spaghetti Casserole.
Step 4: Combine the Filling
In a large mixing bowl, combine the shredded chicken, drained spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded sharp cheddar cheese. Mix everything gently but thoroughly until well blended, ensuring each ingredient is evenly distributed for maximum flavor in your casserole.
Step 5: Assemble the Casserole
Transfer the delicious mixture into the greased casserole dish, spreading it out evenly with a spatula. Top the casserole with the remaining half of the shredded cheddar cheese, allowing it to melt beautifully and create a scrumptious golden crust that will be the highlight of your Spicy Southern Cheesy Chicken Spaghetti Casserole.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 25–30 minutes. Keep an eye on it; you’ll know it’s ready when the cheese is bubbly and golden brown. This final step gives your casserole a beautiful texture while bringing all those wonderful flavors together.
Step 7: Rest and Garnish
Once baking is complete, remove the casserole from the oven and let it rest for about 5 minutes. This allows the flavors to settle. Before serving, garnish with sliced green onions for a fresh, colorful touch, enhancing the delightful presentation of your Cheesy Chicken Spaghetti Casserole.

Expert Tips for Cheesy Chicken Spaghetti Casserole
Perfectly Cooked Chicken: Make sure your chicken is golden brown and cooked through before shredding. Undercooking can result in toughness or unpleasant textures in your casserole.
Al Dente Spaghetti: Remember to cook the spaghetti just until al dente. Overcooked pasta can turn mushy when mixed with the creamy sauce, affecting the whole dish's texture.
Cheese Variety: While sharp cheddar is the star, don't hesitate to mix in different cheeses like Monterey Jack or pepper jack for extra flavor and creaminess in your casserole.
Even Baking: Ensure your casserole is spread evenly in the dish for uniform baking. This helps every bite be equally delicious and prevents some parts from burning while others remain undercooked.
Let It Rest: Allowing the casserole to rest for 5 minutes before serving helps it set, making it easier to dish out without it falling apart. Enjoy every cheesy bite of your creation!
