Step‑by‑Step Instructions for Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, take a moment to grease a large casserole dish with your choice of cooking spray or butter. This will ensure your cheesy casserole doesn’t stick and bakes evenly, paving the way for delicious, gooey goodness.
Step 2: Cook the Chicken
In a large pot or skillet over medium heat, add the boneless, skinless chicken breasts. Sauté them for approximately 6-7 minutes on each side, or until they are golden brown and fully cooked through. Ensure the internal temperature reaches 165°F for food safety, and then set the cooked chicken aside to cool.
Step 3: Boil the Spaghetti
In another pot, bring a large amount of salted water to a boil. Add in the 8 oz. of spaghetti and cook it until al dente, roughly 8-10 minutes. Once cooked, drain the pasta in a colander and set it aside, allowing it to cool slightly while you prepare the remaining ingredients.
Step 4: Mix the Ingredients
In a spacious mixing bowl, combine the cooked chicken, drained spaghetti, one can of cream of chicken soup, chopped bell peppers, garlic powder, paprika, cayenne pepper, and half of the shredded sharp cheddar cheese. Stir everything together gently but thoroughly until the mixture is well combined and every ingredient is evenly coated in creaminess.
Step 5: Assemble the Casserole
Transfer the combined mixture into your greased casserole dish, spreading it evenly across the bottom. Once smoothed, sprinkle the remaining cheddar cheese generously on top for that perfect bubbly crust. The chicken spaghetti casserole is now ready to go into the oven.
Step 6: Bake the Casserole
Place the assembled casserole in the preheated oven and bake for 25-30 minutes. You will know it’s ready when the edges are bubbly and the cheese is golden and melted. Enjoy the intoxicating aroma filling your kitchen as it bakes to perfection.
Step 7: Garnish and Serve
After baking, remove the casserole from the oven and let it cool for about 5 minutes. This resting time helps the flavors settle together. Finally, sprinkle sliced green onions over the top for a pop of color and zesty flavor before serving your delightful Spicy Southern Cheesy Chicken Spaghetti Casserole!
Make Ahead Options
These Spicy Southern Cheesy Chicken Spaghetti Casserole preparations are perfect for busy home cooks looking to save time during hectic weeknights! You can easily cook the chicken and spaghetti up to 24 hours in advance. Simply sauté the chicken, boil the spaghetti, and then mix them with the cream of chicken soup and other ingredients. Store the mixture in an airtight container in the refrigerator until you’re ready to bake. When you’re set to enjoy this delicious casserole, preheat your oven and transfer the mixture to a greased casserole dish, topping it with cheese before baking it for 25-30 minutes.

Expert Tips for Chicken Spaghetti Casserole
• Chicken Check: Ensure the chicken is cooked to an internal temperature of 165°F for food safety. A meat thermometer can help avoid any undercooked bites.
• Al Dente Pasta: Cook spaghetti until just al dente to prevent mushiness. The pasta will absorb some sauce while baking, affecting the overall texture.
• Rest Time: Allow the casserole to rest for about 5 minutes after baking. This helps the flavors meld together beautifully and makes serving easier.
• Veggie Variations: Feel free to sneak in some sautéed mushrooms or other veggies. This adds extra nutrition and flavor to your Chicken Spaghetti Casserole.
• Cheese Choices: Mix different cheese varieties for a unique taste. Try adding a bit of Monterey Jack to the sharp cheddar for creamy exuberance!
• Storage Tips: Leftovers can be stored in an airtight container for up to three days. Reheat in the oven for best results—the cheese will reclaim its melty goodness!
Chicken Spaghetti Casserole Recipe FAQs
How do I choose the right ripeness for chicken breasts?
Absolutely! When selecting chicken breasts, look for ones that are firm to the touch and have a pink hue. Avoid any with discoloration or dark spots. Fresh chicken should not have a strong odor; if it does, it’s best to steer clear.
What’s the best way to store leftover Chicken Spaghetti Casserole?
To keep your casserole fresh, store leftovers in an airtight container in the fridge for up to 3 days. This ensures that it remains moist and delicious. When you’re ready to enjoy, simply reheat in the microwave or oven until warmed through.
Can I freeze Chicken Spaghetti Casserole?
Yes! For freezing, let the casserole cool completely before transferring it to a freezer-safe container. Seal it tight and store it in the freezer for up to 2 months. To reheat, thaw overnight in the fridge, and warm in the oven at 350°F for about 20-25 minutes until everything is heated through.
What if my casserole comes out too dry?
No problem! If your Chicken Spaghetti Casserole seems dry, it may be due to overcooked pasta or not enough moisture. To remedy this, try mixing in a bit more cream of chicken soup or adding extra cheese before baking. Always cook the pasta al dente, as it will absorb some of the moisture while baking.
Is this recipe safe for people with allergies?
Very important! This recipe contains chicken, dairy, and potentially gluten from the spaghetti. For a safe twist, opt for gluten-free pasta and check that your cream of chicken is free from allergens. Always be mindful of any specific allergies by reading ingredient labels carefully.
