Ingredients
To prepare this delicious Spicy Southern Cheesy Chicken Spaghetti Casserole, you’ll need the following 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)
Step-by-Step Instructions
1. Preheat the oven: Preheat your oven to 350°F (175°C) and grease a large casserole dish. The anticipation of that golden finish is half the fun!
2. Cook the chicken: In a large pot over medium heat, cook the chicken for about 6-7 minutes per side until golden and cooked through. This will infuse your kitchen with a mouthwatering aroma.
3. Prepare the spaghetti: Boil salted water and cook the spaghetti until al dente (about 8-10 minutes). Drain it and set aside, letting the steam rise so you can savor the fragrance.
4. Mix the ingredients: In a large bowl, combine the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, spices, and half of the cheddar cheese. Stir until everything is well combined and the mixture is silky smooth.
5. Transfer and bake: Pour the mixture into the greased casserole dish and top it with the remaining cheddar cheese. Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown. Your kitchen will feel like a cozy Southern home!
6. Garnish and serve: Allow the casserole to rest for 5 minutes before garnishing with chopped green onions. Serve warm and watch everyone dive in with smiles.

Variations
- Vegan Version: Substitute chicken with grilled tofu or chickpeas, and swap cream of chicken soup for a plant-based alternative.
- Spicy Twist: Add sliced jalapeños for an extra kick or use pepper jack cheese instead of sharp cheddar.
- Ingredient Swaps: Experiment with different veggies like zucchini or mushrooms, or use whole grain spaghetti for a healthy alternative!
Serving Suggestions
Pair your Spicy Southern Cheesy Chicken Spaghetti Casserole with a crisp green salad or cornbread for a complete meal. It is perfect for family dinners, potlucks, or cozy gatherings.
Tips for Success
- Cook Chicken Thoroughly: Ensure your chicken is fully cooked for the best texture.
- Don’t Overcook the Spaghetti: You want it al dente as it will further cook in the oven.
