Spicy Southern Cheesy Chicken Spaghetti Casserole is one of those dishes that brings the whole family together around the table. It is creamy, cheesy, loaded with a gentle spicy kick, and wonderfully comforting for busy weeknights or potlucks alike

It all started when I was looking for a little twist on a basic chicken bake and decided to add cayenne for just enough kick after that the casserole became a Sunday favorite

Ingredients

  • Boneless skinless chicken breasts: The main protein look for firm fresh fillets
  • Spaghetti: Holds the sauce and makes the dish hearty use classic or whole wheat
  • Shredded sharp cheddar cheese: Delivers rich flavor freshly shredded melts best
  • Fresh bell peppers: Adds color and a mild bite go for firm glossy peppers in any color
  • Cream of chicken soup: Creates the creamy sauce choose one with simple ingredients
  • Paprika: Smoky and sweet choose a good quality for balanced flavor
  • Cayenne pepper: The spicy kick add more if you like it hot
  • Garlic powder: Brings depth of flavor a kitchen staple
  • Green onions: Sliced on top for a fresh finish look for crisp bright greens

Step-by-Step Instructions

Prepare the Oven and Dish:
Set the oven to 350 degrees Fahrenheit and grease a large casserole dish so the casserole will not stick and cleanup is easy
Cook the Chicken:
Place the chicken breasts in a large pot over medium heat Let them cook for 6 to 7 minutes per side until they are golden all over and cooked through Inside should be moist but no longer pink Then let them cool slightly and shred into bite-sized pieces
Boil the Spaghetti:
Bring a pot of salted water to a boil Add the spaghetti and cook until it is al dente usually 8 to 10 minutes Drain thoroughly Set aside You want the noodles just cooked so they soak up the sauce but do not get mushy
Mix the Casserole Base:
In a big bowl stir together the shredded chicken cooked spaghetti cream of chicken soup bell peppers paprika cayenne garlic powder and half the cheddar cheese Mix until everything is evenly coated and cheese begins to blend
Assemble and Bake:
Pour this mixture into your greased casserole dish Spread out evenly Sprinkle the rest of the cheddar cheese over the top Bake for 25 to 30 minutes until the dish is bubbly and the cheesy top is golden
Rest and Serve:
Let the casserole sit for 5 minutes after baking so it sets up and slices cleanly Scatter sliced green onions across the top and serve hot

I have always loved the flavor that sharp cheddar brings to a dish Its tang is perfect against the creamy sauce and the peppery bite Growing up my mom would let me grate the cheese and nibble the corners straight from the block nothing compares to fresh cheese in a casserole like this

Storage Tips

If you have leftovers just cover the cooled casserole tightly and keep it in the fridge for up to three days The flavors develop even more overnight For reheating I like to use the oven covered at 325 degrees Fahrenheit so the cheese stays melty and the pasta does not dry out

Ingredient Substitutions

No cheddar on hand Try Monterey Jack or pepper jack for extra kick Glutenfree pasta works well too If you want another veggie swap in diced poblano peppers or chopped spinach You can also make it with rotisserie chicken for a shortcut

Serving Suggestions

Serve big hearty squares with a crisp green salad and garlic bread If you want a twist top with a spoonful of salsa or a dollop of sour cream It is also perfect served at parties for brunches or as leftovers for lunch the next day

Ingredients

→ Main Ingredients

01 3 to 4 boneless, skinless chicken breasts (approximately 1.5 pounds)
02 8 ounces dried spaghetti
03 2 cups shredded sharp cheddar cheese
04 1 cup chopped fresh bell peppers
05 1 can (10.5 ounces) condensed cream of chicken soup
06 1 teaspoon paprika
07 1/2 teaspoon cayenne pepper
08 1 teaspoon garlic powder
09 1/4 cup sliced green onions

Instructions

Step 01

Preheat oven to 350°F (175°C). Lightly grease a large casserole dish.

Step 02

In a large pot, cook chicken breasts over medium heat for 6–7 minutes per side until golden and fully cooked. Let cool slightly, then shred the chicken.

Step 03

Bring a large pot of salted water to a boil. Cook spaghetti for 8–10 minutes until al dente. Drain and set aside.

Step 04

In a large bowl, combine shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the cheddar cheese. Mix thoroughly until evenly blended.

Step 05

Transfer mixture into the prepared casserole dish. Sprinkle the remaining cheddar cheese evenly on top. Bake in the preheated oven for 25–30 minutes, or until the casserole is bubbly and the cheese is golden brown.

Step 06

Remove from the oven and let rest for 5 minutes. Garnish with sliced green onions before serving.

Notes

  1. For added flavor, a blend of red and green bell peppers may be used. Allowing the casserole to rest after baking helps slices hold their shape.
