Step‑by‑Step Instructions for Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While that warms up, grease a large casserole dish with cooking spray or a light coat of oil to prevent sticking. This ensures the Spicy Southern Cheesy Chicken Spaghetti Casserole comes out easily once cooked and helps achieve a golden crust.
Step 2: Cook the Chicken
In a large pot, heat a drizzle of oil over medium heat. Add the boneless, skinless chicken breasts and cook for about 6-7 minutes per side until they are golden brown and cooked through, reaching an internal temperature of 165°F (75°C). This creates a flavorful base for the casserole as the chicken stays juicy and tender.
Step 3: Prepare the Spaghetti
While the chicken cooks, bring a large pot of salted water to a boil. Once boiling, add the spaghetti and cook according to package instructions until al dente, usually about 8-10 minutes. Drain the cooked spaghetti and set it aside, allowing excess water to exit so that the casserole remains creamy rather than watery.
Step 4: Combine the Mixture
In a large mixing bowl, shred the cooked chicken into bite-sized pieces. Then add the cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded sharp cheddar cheese. Mix everything thoroughly until the pasta and chicken are evenly coated with the creamy sauce and spices.
Step 5: Assemble the Casserole
Transfer the combined mixture into the greased casserole dish. Spread it evenly, pressing down slightly to ensure an even layer. Top the casserole with the remaining shredded cheddar cheese, creating a gooey, cheesy layer that will melt beautifully during baking.
Step 6: Bake to Perfection
Place the casserole dish in the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the top is bubbly and golden brown, beckoning you with its delicious aroma. This baking process melds all the flavors together, creating a comforting Spicy Southern Cheesy Chicken Spaghetti Casserole.
Step 7: Garnish and Serve
After baking, remove the casserole from the oven and let it rest for about 5 minutes. This resting period helps the casserole set so it’s easier to cut into squares. Garnish with sliced green onions for a fresh pop of color and flavor before serving. Enjoy the delightful warm dish with family and friends!
Make Ahead Options
These Spicy Southern Cheesy Chicken Spaghetti Casserole components are perfect for meal prep, saving you time on busy weeknights! You can prepare the entire dish up to 24 hours in advance; simply assemble it in the casserole dish and cover tightly with plastic wrap before refrigerating. For the best quality, make sure to let it come to room temperature for about 30 minutes before baking. To keep everything fresh, avoid adding the remaining cheese until just before baking. When you’re ready to serve, bake it for 30-35 minutes instead of 25-30, until bubbly and golden brown. Enjoy the convenience of a homemade meal that’s just as delicious as when freshly made!

Spicy Southern Cheesy Chicken Spaghetti Casserole Recipe FAQs
How do I select the best chicken for the casserole?
Absolutely! When choosing chicken breasts, look for the ones that are plump, with no dark spots or discoloration. Fresh breasts have a moist feel, and if you’re opting for frozen, ensure they’re well-packaged without any freezer burn.
What’s the best way to store leftovers?
You can store leftovers in an airtight container in the fridge for up to 3 days. When reheating, I often recommend using the oven for the best results—just pop it in at 350°F (175°C) until warmed throughout.
Can I freeze the Spicy Southern Cheesy Chicken Spaghetti Casserole?
Absolutely! To freeze, wrap the casserole tightly in plastic wrap and then in aluminum foil. It can be stored in the freezer for up to 3 months. Just remember to label it so you know what you have!
What should I do if the casserole comes out too dry?
If your casserole turns out dry, it’s usually due to overcooked chicken or not enough sauce. To remedy this, you can add a bit of chicken broth or cream of chicken soup to the mixture next time. Ensuring to cook the chicken just until it reaches 165°F (75°C) will help maintain juiciness.
Is this casserole suitable for dietary restrictions?
Yes! If you’re accommodating dietary restrictions, you can easily adjust the recipe. Substitute chicken with cooked shrimp or tofu, and use gluten-free pasta to make it gluten-free. For dairy allergies, opt for non-dairy cheese and a cream sauce that suits your needs.
How can I make the casserole spicier?
For those who love heat, increase the cayenne pepper to 1 teaspoon or add some diced jalapeños or hot sauce to enhance the spice level. The more, the merrier when it comes to flavor! If the spice is too intense, a dollop of sour cream on top when serving helps to cool it down.
