Step‑by‑Step Instructions for Irresistible Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it warms, grease a large casserole dish with cooking spray or butter, ensuring it’s evenly coated to prevent sticking. This is a crucial step to achieve a beautifully baked Irresistible Spicy Southern Cheesy Chicken Spaghetti Casserole that releases easily when it’s time to serve.
Step 2: Cook the Chicken
In a large pot, heat a drizzle of olive oil over medium heat. Add the boneless, skinless chicken breasts and cook for 6-7 minutes per side until they turn golden brown and are no longer pink in the center. Use a meat thermometer to check for doneness; the internal temperature should reach 165°F (75°C). Once done, remove from heat and let them rest.
Step 3: Boil the Spaghetti
Bring a pot of salted water to a rolling boil, then add the spaghetti and cook for 8-10 minutes until al dente. Stir occasionally to prevent sticking. After cooking, drain the spaghetti in a colander and set aside. This step ensures that the pasta maintains its texture and can soak up the rich flavors later in the casserole.
Step 4: Combine Ingredients
In a large mixing bowl, shred the cooked chicken into bite-sized pieces. Add the drained spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded cheddar cheese. Stir until everything is well combined, creating a creamy mixture filled with the essence of the Irresistible Spicy Southern Cheesy Chicken Spaghetti Casserole.
Step 5: Assemble the Casserole
Transfer the chicken and spaghetti mixture into the prepared casserole dish, spreading it evenly. Top with the remaining shredded cheddar cheese to form a delightful cheesy crust once baked. This layering not only adds flavor but ensures that every bite has a cheesy finish, making this casserole truly irresistible.
Step 6: Bake to Perfection
Place the casserole in your preheated oven and bake for 25-30 minutes. You’ll know it’s ready when the cheese is bubbly and golden brown, emitting a mouthwatering aroma that fills your kitchen. This baking process is critical for melding all the flavors together into a cohesive dish.
Step 7: Rest and Garnish
After baking, remove the casserole from the oven and allow it to rest for about 5 minutes. This resting period lets the flavors meld and makes it easier to serve. Once rested, sprinkle the top with sliced green onions for a fresh, vibrant garnish that enhances the overall flavor profile of your Irresistible Spicy Southern Cheesy Chicken Spaghetti Casserole before serving.
