Step‑by‑Step Instructions for Cheesy Chicken Spaghetti Casserole Step 1: Preheat the Oven Begin by preheating your oven to 350°F (175°C). While the oven is warming up, take a moment to grease a large casserole dish with cooking spray or a little olive oil to prevent sticking. This will ensure that your Cheesy Chicken Spaghetti Casserole easily slides out when it’s done and allows for easy serving. Step 2: Cook the Chicken In a large skillet or pot over medium heat, add the boneless, skinless chicken breasts. Cook for about 6-7 minutes per side until they are golden brown and fully cooked through, achieving an internal temperature of 165°F (75°C). Once cooked, transfer the chicken to a plate and let it rest briefly before shredding it into bite-sized pieces, creating tender morsels for the casserole. Step 3: Cook the Spaghetti While the chicken is cooking, bring a large pot of salted water to a boil. Once boiling, add the spaghetti and cook for about 8-10 minutes until it reaches an al dente texture. When finished, drain the pasta in a colander and set it aside. This step ensures your pasta will hold up well in the Cheesy Chicken Spaghetti Casserole without becoming mushy during baking. Step 4: Combine the Ingredients In a large mixing bowl, combine the shredded chicken, drained spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded cheddar cheese. Mix everything together until well combined, making sure each ingredient is evenly distributed for a deliciously cohesive flavor in your casserole. Step 5: Assemble the Casserole Transfer the chicken and pasta mixture into your greased casserole dish, spreading it out evenly. Sprinkle the remaining shredded cheddar cheese generously over the top, creating a luscious, cheesy layer that will melt beautifully while baking. This cheesy goodness is what makes the Cheesy Chicken Spaghetti Casserole truly irresistible. Step 6: Bake to Perfection Place the assembled casserole in the preheated oven and bake for about 25-30 minutes. You’ll know it’s ready when the top is bubbly and golden brown, creating a delightful crust that promises gooey cheese with every bite. The comforting aroma will fill your kitchen, making it hard to wait! Step 7: Rest and Garnish After removing the casserole from the oven, allow it to rest for about 5 minutes. This wait helps the flavors meld together while making it easier to serve. Before diving in, sprinkle sliced green onions over the top for a fresh touch of color and flavor, enhancing your Cheesy Chicken Spaghetti Casserole experience! Make Ahead Options These Spicy Southern Cheesy Chicken Spaghetti Casserole preparations are perfect for busy weeknights!

This will allow the flavors to meld together beautifully, making it even more delicious when baked. When you’re ready to enjoy it, just remove it from the fridge and bake as directed, adding an extra 5-10 minutes to the cooking time to ensure it’s thoroughly heated. By prepping ahead, you’ll have a comforting meal ready with minimal effort, just waiting to warm your family’s hearts!
