How to Make Irresistible Spicy Southern Cheesy Chicken Spaghetti Casserole

Preheat the oven
Begin by preheating your oven to 350°F (175°C). Grease a large casserole dish with a bit of oil or butter to prevent sticking.
Cook the chicken
In a large pot, cook the boneless, skinless chicken breasts over medium heat for about 6-7 minutes on each side. You want them golden brown and fully cooked through.
Boil the spaghetti
Bring a pot of salted water to a boil. Add in your spaghetti and cook according to package instructions until al dente, usually around 8-10 minutes. Drain and set aside.
Mix the casserole ingredients
In a large mixing bowl, combine the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded cheddar cheese. Mix well until combined.
Transfer to the casserole dish
Pour the mixture into your greased casserole dish. Spread it out evenly and top it with the remaining shredded cheddar cheese for that irresistible cheesy crust.
Bake to perfection
Place the casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s ready when the cheese is bubbly and golden brown on top.
Rest and garnish
Once baked, remove the casserole from the oven and let it rest for about 5 minutes. This makes serving easier. Before serving, sprinkle chopped green onions on top for a fresh touch.

Optional: Serve with a side salad for a refreshing contrast.
