Step‑by‑Step Instructions for Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) while you prepare the casserole dish. Grease a large casserole dish with cooking spray or butter to prevent sticking. The warm kitchen will soon be filled with the comforting aroma of the Spicy Southern Cheesy Chicken Spaghetti Casserole.
Step 2: Cook the Chicken
In a large pot over medium heat, add boneless, skinless chicken breasts and cook for 6-7 minutes on each side until they turn golden brown and are no longer pink in the center. Use a meat thermometer to ensure an internal temperature of 165°F (75°C). Once cooked, remove the chicken, let it cool slightly, and then dice it into bite-sized pieces.
Step 3: Boil the Pasta
In a large pot, bring salted water to a boil for the spaghetti. Cook the spaghetti for 8-10 minutes until it reaches an al dente texture, then drain it in a colander. Allow it to cool slightly while the flavors of your Spicy Southern Cheesy Chicken Spaghetti Casserole come together.
Step 4: Mix Ingredients
In a massive mixing bowl, combine the diced chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded cheddar cheese. Stir the mixture thoroughly until every ingredient is well-coated, blending all those rich, southern flavors.
Step 5: Transfer to Dish
Pour the delicious chicken and spaghetti mixture into your greased casserole dish, spreading it evenly with a spatula. Then, sprinkle the remaining cheddar cheese over the top, creating a cheesy, inviting layer that promises to melt to perfection as it bakes.
Step 6: Bake in the Oven
Place the casserole in the preheated oven and bake for 25-30 minutes. Watch for a bubbly, golden-brown top layer that indicates your Spicy Southern Cheesy Chicken Spaghetti Casserole is ready to be enjoyed.
Step 7: Garnish and Serve
Once baked, remove the casserole from the oven and let it sit for about 5 minutes before serving. This allows the layers to settle. Finally, sprinkle sliced green onions over the top for a fresh garnish, and then dig in while it’s still warm for that soul-soothing comfort.
