This spicy southern cheesy chicken spaghetti casserole brings together the nostalgic comfort of pasta with zesty southern flavors in one bubbling dish. I discovered this recipe during a particularly busy season when I needed something that could feed my family for multiple meals while still feeling special enough for weekend dinners.
This casserole became my signature potluck dish after bringing it to a neighborhood gathering where three different people asked for the recipe before the night was over. The combination of creamy texture with spicy kick creates that perfect comfort food balance.
Ingredients
- Boneless skinless chicken breasts: add lean protein and absorb all the flavors of the seasonings. Look for even sized pieces for consistent cooking.
- Spaghetti: forms the hearty base. Choose a quality brand that holds its shape when baked.
- Sharp cheddar cheese: provides that stretchy meltiness and bold flavor. Freshly grated melts much better than pre shredded varieties.
- Fresh bell peppers: add sweetness and texture. Select firm colorful peppers for best flavor and visual appeal.
- Cream of chicken soup: creates the creamy binding sauce without requiring a homemade roux.
- Paprika: adds subtle smoky depth. Spanish paprika offers the richest flavor profile.
- Cayenne pepper: brings the signature southern heat. Adjust according to your spice preference.
- Garlic powder: infuses aromatic flavor throughout the dish. Fresh garlic can burn in the long bake time.
- Green onions: provide a fresh finish and pop of color. Choose bunches with vibrant green tops.
Step-by-Step Instructions
- Prep Your Baking Dish:
- Preheat your oven to 350°F and thoroughly grease a large casserole dish with butter or cooking spray. A 9x13 inch dish works perfectly for this recipe allowing the casserole to spread evenly for consistent cooking throughout.
- Cook The Chicken:
- Place chicken breasts in a large pot with about an inch of water or chicken broth. Cook over medium heat for approximately 6 to 7 minutes per side until the internal temperature reaches 165°F. The chicken should have a light golden exterior while remaining juicy inside. Let cool slightly before shredding with two forks into bite sized pieces.
- Prepare The Pasta:
- Bring a large pot of water to a rolling boil and add a generous tablespoon of salt. Cook the spaghetti until just al dente about 8 minutes or 2 minutes less than package directions suggest. The pasta will continue cooking in the oven so slightly undercooking it now prevents mushiness later. Drain thoroughly but do not rinse to help the sauce adhere better.
- Combine The Ingredients:
- In a large mixing bowl gently fold together 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 until everything is evenly coated in the creamy sauce ensuring there are no dry spots but being careful not to break the pasta.
- Assemble And Bake:
- Transfer the mixture to your prepared casserole dish spreading it evenly to the edges. Sprinkle the remaining cheddar cheese over the top creating a generous cheese layer that will become golden and bubbly. Bake uncovered for 25 to 30 minutes until the edges are bubbling and the cheese has developed appealing golden brown spots.
- Rest And Serve:
- Allow the casserole to rest for 5 minutes after removing from the oven. This critical step helps the sauce set slightly making it easier to serve in neat portions. Sprinkle freshly sliced green onions over the top just before bringing to the table for a pop of color and fresh flavor.

This casserole reminds me of Sunday dinners at my grandmother's house in Georgia where spice was never optional but a requirement. She would always add an extra pinch of cayenne while winking at me saying "The secret to making people remember your cooking is giving it just enough kick to wake up their taste buds."

Make It Your Own
The basic framework of this recipe welcomes creative adaptations based on your preferences or what you have available. Try using rotisserie chicken to save time or substitute turkey for a lighter option. Pepper jack cheese can replace some or all of the cheddar for extra spiciness. For a vegetable boost add a cup of frozen peas carrots or corn directly to the mixture before baking. Mushrooms sautéed with the bell peppers add wonderful umami depth for mushroom lovers.
Serving Suggestions
