Step‑by‑Step Instructions for Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat & Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms, grease a large casserole dish with cooking spray or butter to prevent sticking. This will ensure your Spicy Southern Cheesy Chicken Spaghetti Casserole comes out perfectly golden and easy to serve.
Step 2: Cook Chicken
In a large pot over medium heat, add the boneless, skinless chicken breasts. Cook for 6-7 minutes on each side until the chicken is golden brown and fully cooked through, reaching an internal temperature of 165°F (75°C). Remove the chicken from the pot and let it cool slightly before shredding it into bite-sized pieces.
Step 3: Boil Pasta
In a large pot, bring salted water to a boil and add 8 oz of spaghetti. Cook the pasta for 8-10 minutes until al dente, stirring occasionally to prevent sticking. Once done, drain the spaghetti and set it aside in a large mixing bowl, ready to be combined with the other ingredients.
Step 4: Mix Ingredients
In the same mixing bowl with the spaghetti, add the shredded chicken, 1 can of cream of chicken soup, 1 cup of chopped bell peppers, 1 tsp of paprika, 1/2 tsp of cayenne pepper, 1 tsp of garlic powder, and 1 cup of shredded sharp cheddar cheese. Mix everything well until all ingredients are fully combined and coated in the creamy mixture.
Step 5: Bake
Transfer the combined mixture into your greased casserole dish, spreading it evenly. Top the casserole with the remaining 1 cup of sharp cheddar cheese. Place it in the preheated oven and bake for 25-30 minutes, or until the top is bubbly and golden brown, creating a deliciously crispy crust.
Step 6: Garnish & Serve
After baking, remove the casserole from the oven and let it rest for about 5 minutes to set. Before serving, garnish with 1/4 cup of sliced green onions for a pop of freshness and color. Cut into portions and enjoy your hearty Spicy Southern Cheesy Chicken Spaghetti Casserole with family or friends!
