This Spicy Southern Chicken Spaghetti Casserole is comfort food with a kick! Creamy, cheesy, and packed with bold flavor, it’s a hearty dish that brings the warmth of Southern kitchens straight to your table. Perfect for weeknights or potlucks, this casserole bakes up golden and bubbly every time.

Ingredients

  • 3–4 boneless, skinless chicken breasts (about 1.5 lbs)
  • 8 oz spaghetti
  • 2 cups shredded sharp cheddar cheese
  • 1 cup fresh bell peppers, chopped
  • 1 can (10.5 oz) cream of chicken soup
  • 1 tsp paprika
  • 1/2 tsp cayenne pepper
  • 1 tsp garlic powder
  • 1/4 cup green onions, sliced

Instructions

Step 1: Prepare the Oven and Chicken

Preheat your oven to 350°F (175°C) and lightly grease a large casserole dish. Cook the chicken in a skillet over medium heat for about 6–7 minutes per side, until golden and fully cooked through. Shred the chicken and set aside.

Step 2: Cook the Spaghetti

Bring a large pot of salted water to a boil. Add the spaghetti and cook for 8–10 minutes, just until al dente. Drain and set aside.

Step 3: Mix Everything Together

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

Step 4: Bake Until Golden

Transfer the mixture into the greased casserole dish. Sprinkle the remaining cheese on top and bake for 25–30 minutes, or until the top is bubbly and lightly browned.

Step 5: Garnish and Serve

Let the casserole rest for 5 minutes before serving. Top with sliced green onions for a pop of color and freshness. Enjoy that spicy, creamy Southern flavor in every bite!
