Spicy Southern Cheesy Chicken Spaghetti Casserole brings serious comfort to our dinner table. Creamy cheese and a little kick of spice blend with tender chicken and spaghetti for a satisfying, crowd-pleasing meal. When my family gathers on a chilly weeknight, nothing gets more smiles than this bubbling casserole coming out of the oven.

I first created this casserole when a neighbor dropped by with extra peppers from her garden. It instantly became a must-have at Sunday potlucks. My teenager even requests the leftovers for lunch the next day.

Ingredients

  • Boneless skinless chicken breasts: Choose fresh or thawed pieces for best results These turn fork tender after baking
  • Spaghetti: Classic white or whole wheat both work as a satisfying base Make sure to cook to al dente so it holds up in the casserole
  • Shredded sharp cheddar cheese: Go for a brick and shred it yourself if you can It melts smoother and tastes richer than the bagged kind
  • Fresh bell peppers: Chopped red or green bell peppers add sweetness and color Pick firm peppers without wrinkles for crunch
  • Cream of chicken soup: This acts as the creamy binder Look for low sodium varieties for a lighter sauce
  • Paprika: Brings a sweet smoky warmth Smoked or regular paprika both shine here
  • Cayenne pepper: A pinch turns up the Southern heat Adjust to your spice comfort level
  • Garlic powder: Adds aromatic depth Be sure it is fresh for best flavor
  • Green onions: Sliced and scattered on top for a fresh zippy finish Pick bunches with vivid green tops and no wilting

Step-by-Step Instructions

Prepare the Oven and Dish:
Set your oven to 350 degrees Fahrenheit and grease a large casserole dish with butter or spray This keeps noodles from sticking and creates better browning
Cook the Chicken:
Place the chicken breasts in a large skillet with a splash of oil Cook over medium heat turning once until both sides are golden and the centers feel firm about 6 to 7 minutes per side Remove and let rest so juices can redistribute then shred with two forks
Boil the Spaghetti:
Fill a big pot with water and add a good handful of salt Bring to a boil then add the spaghetti Cook for 8 to 10 minutes until just al dente so it does not get mushy later Drain and set aside
Mix It Together:
In a large bowl combine the shredded chicken cooked spaghetti cream of chicken soup chopped bell peppers paprika cayenne and garlic powder Toss until everything is coated evenly Fold in half of the cheddar cheese now for extra gooeyness
Assemble and Bake:
Pour the noodle and chicken mixture into your prepared dish Spread it out then scatter the remaining cheddar cheese all over the top Bake for 25 to 30 minutes until the casserole is bubbling and the cheese turns golden with crisp edges
Garnish and Serve:
Let the casserole rest for 5 minutes so it can set Slice green onions and sprinkle generously over the top before serving for a fresh punch

The bell pepper is my favorite part here It always reminds me of my grandmother’s garden harvests where she used whatever was ripe that day My kids love picking out their favorite vegetable color to toss in

How to Store Leftovers

Transfer any leftover casserole to an airtight container and refrigerate once it has cooled Do not leave the pan out for more than two hours for food safety This dish keeps well in the fridge for up to four days Reheat portions in the microwave or covered in the oven until hot

Easy Ingredient Swaps

Rotisserie chicken works wonderfully if you do not have time to cook raw chicken Breasts or thighs both work Monterey Jack or Colby can stand in for cheddar if you are out of it Swap cream of chicken for cream of mushroom soup to add earthy flavor or use a gluten free soup for special diets

Serving Ideas

I like to add a simple green salad or steamed broccoli alongside this casserole to brighten up the meal For a full Southern spread serve it with cornbread or baked beans A dash of hot sauce gives it extra personality at the table
