This spicy Southern cheesy chicken spaghetti casserole is a comfort dish that melts together creamy cheese, tender chicken, and just the right amount of heat. Perfect for family dinners or when you want something hearty and satisfying without a lot of fuss.
I made this casserole for a casual weekend dinner, and it quickly became a favorite in our household. The combination of melted cheese and spicy paprika keeps everyone going back for seconds.
Ingredients
- Boneless skinless chicken breasts: about one and a half pounds for juicy, tender protein
- Spaghetti: eight ounces for a filling base that soaks up all the flavors well
- Sharp cheddar cheese: two cups shredded to bring tang and great meltiness
- Fresh bell peppers: one cup chopped adds a sweet crunch and color
- Cream of chicken soup: one ten and a half ounce can binds everything in a creamy sauce
- Paprika: one teaspoon for a smoky depth of flavor
- Cayenne pepper: half a teaspoon to add a gentle but noticeable heat
- Garlic powder: one teaspoon enhances savory notes
- Green onions: quarter cup sliced for a fresh garnish that brightens the dish
Step-by-Step Instructions
- Sear the Chicken:
- Cook the chicken breasts in a large pot over medium heat for six to seven minutes on each side until they turn golden and are cooked through. This step seals in the juiciness and builds flavor.
- Cook the Spaghetti:
- Boil salted water and cook your spaghetti for eight to ten minutes until it is just al dente. Drain well and set aside so it doesn’t overcook in the oven.
- Combine the Mixture:
- In a large bowl, mix together the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the sharp cheddar cheese. Stir until everything is evenly coated.
- Assemble the Casserole:
- Grease your casserole dish and pour in the chicken and spaghetti mixture. Smooth it out evenly. Sprinkle the remaining cheddar cheese on top for a beautiful golden crust.
- Bake to Perfection:
- Place the dish in a 350 degree Fahrenheit oven and bake for 25 to 30 minutes until bubbly and golden on top.
- Rest and Garnish:
- Remove from the oven and let it rest for five minutes. Sprinkle freshly sliced green onions over the top before serving. This adds a fresh bite and some vibrant color.

My favorite ingredient here is the sharp cheddar cheese which brings so much personality to this recipe. I remember making this for a family gathering and watching everyone eagerly dig in, commenting on the perfect cheesy crust.
