Step‑by‑Step Instructions for Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat Oven
Start by preheating your oven to 350°F (175°C). While it heats, take a large casserole dish and grease it lightly with cooking spray or butter to prevent sticking. This will ensure that your Spicy Southern Cheesy Chicken Spaghetti Casserole comes out perfectly golden and intact.
Step 2: Cook Chicken
In a large skillet, heat a drizzle of olive oil over medium heat. Add the boneless, skinless chicken breasts and sauté for 6-7 minutes per side until they turn golden brown and are cooked through, reaching an internal temperature of 165°F (74°C). Remove from the skillet, let cool slightly, and then shred the chicken into bite-sized pieces.
Step 3: Boil Pasta
Bring a large pot of salted water to a boil and add the spaghetti. Cook until al dente, about 8-10 minutes, stirring occasionally to avoid sticking. Once done, drain the pasta in a colander and let it sit briefly to cool and dry, preventing clumping when mixed with the other ingredients.
Step 4: Combine Ingredients
In a large mixing bowl, combine the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the sharp cheddar cheese. Mix well until all ingredients are thoroughly coated and evenly distributed, creating a colorful and flavorful mixture for your casserole.
Step 5: Bake Casserole
Transfer the chicken and pasta mixture into the greased casserole dish, spreading it evenly. Top with the remaining cheddar cheese, creating a cheesy crust. Bake in the preheated oven for 25-30 minutes or until the casserole is bubbly and the cheese is melted and golden brown, filling your kitchen with a rich aroma.
Step 6: Garnish and Serve
Once baked, carefully remove the casserole from the oven and let it rest for about 5 minutes to set. Just before serving, sprinkle fresh chopped green onions on top for a pop of color and flavor. This Spicy Southern Cheesy Chicken Spaghetti Casserole is now ready to be enjoyed, serving up smiles at your family table!
