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 the oven heats, grab a large casserole dish and generously grease it with cooking spray or butter to prevent sticking. This step is crucial to ensure your Spicy Southern Cheesy Chicken Spaghetti Casserole slides out easily and has a beautifully baked crust.
Step 2: Cook the Chicken
In a large skillet or pot, heat a drizzle of oil over medium heat. Add boneless, skinless chicken breasts to the pan and cook for 6–7 minutes on each side, until golden brown and cooked through to an internal temperature of 165°F (75°C). This gives the chicken a nice sear while infusing it with flavor; set aside to cool slightly before shredding.
Step 3: Boil the Spaghetti
In a large pot, bring salted water to a rolling boil. Add the spaghetti and cook according to package instructions, typically 8–10 minutes, until al dente. Drain the pasta and toss it with a little olive oil to prevent sticking, then set aside. This pasta will be the heart of your Spicy Southern Cheesy Chicken Spaghetti Casserole.
Step 4: Combine Ingredients
In a big mixing bowl, combine the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, and your chosen spices—paprika, cayenne pepper, and garlic powder. Mix well until everything is coated in the creamy soup base. The vibrant colors and enticing aromas set the stage for an amazing casserole experience.
Step 5: Assemble the Casserole
Transfer the mixture into your prepared casserole dish, spreading it out evenly. Make sure the mixture is nicely distributed for even baking. Top the casserole with the remaining sharp cheddar cheese, allowing it to melt into a gooey, delicious crown as it bakes. This cheesy layer ensures that each bite of your Spicy Southern Cheesy Chicken Spaghetti Casserole is utterly irresistible.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 25–30 minutes, or until the cheese is wonderfully bubbly and golden brown on top. Keep an eye on it—when you see the cheese starting to brown, you know it’s almost ready! Your kitchen will be filled with the mouthwatering scent of comfort as you await this comforting dish.
Step 7: Cool and Garnish
Once out of the oven, let the casserole rest for about 5 minutes to set. This cooling period allows the flavors to meld beautifully. Before serving, sprinkle chopped green onions over the top for a fresh and crunchy garnish. Enjoy diving into your creamy and flavorful Spicy Southern Cheesy Chicken Spaghetti Casserole!
