Step-by-Step Instructions

Creating this cheesy chicken spaghetti is a straightforward process. Just follow these simple steps.

1. 
   

   Cook the Pasta: Preheat your oven to 350°F. Cook the spaghetti according to package directions until al dente. Drain well. Pro Tip: Do not overcook the pasta, as it will continue to cook in the oven.

   
   
2. 
   

   Combine the Sauce: In a large mixing bowl, combine the cream of chicken soup, undrained diced tomatoes and green chilies, sour cream, chicken broth, garlic powder, onion powder, and cayenne pepper. Stir until the mixture is smooth and well-combined.

   
   
3. 
   

   Bring it All Together: Add the cooked and drained spaghetti, shredded chicken, 1 cup of cheddar cheese, and the cubed Velveeta to the sauce. Gently fold everything together until the pasta and chicken are evenly coated in the creamy, spicy sauce.

   
   
4. 
   

   Assemble and Bake: Transfer the entire mixture to a greased 9×13 inch baking dish. Spread it out into an even layer. Sprinkle the remaining 1 cup of cheddar cheese and the Parmesan cheese evenly over the top.

   
   
5. 
   

   Bake to Perfection: Bake for 25-30 minutes, or until the cheese is completely melted and the casserole is bubbly around the edges. For a more golden top, you can broil for the last 1-2 minutes, watching carefully to prevent burning.

   
   
6. 
   

   Rest and Serve: Let the baked chicken spaghetti rest for about 5 minutes after pulling it from the oven. This allows the sauce to set slightly for easier serving. Garnish with fresh parsley if desired.

Common Mistakes to Avoid

Avoid these simple pitfalls for the best possible spicy Southern chicken spaghetti casserole.

• Overcooking the Pasta: This is the most common mistake. Mushy pasta will make the final casserole texture soft and mushy. Always cook to al dente.
• Not Seasoning the Sauce: Taste your sauce mixture before combining it with the pasta and chicken. You may want to add a pinch of salt and black pepper.
• Skipping the Rest Time: Letting the casserole sit for 5 minutes after baking allows the sauce to thicken, making it much easier to serve neat portions.
• Using Cold Chicken: If you are using refrigerated cooked chicken, let it come to room temperature for a bit or warm it slightly so it does not cool down your sauce.

Storing Tips for the Recipe

This chicken spaghetti casserole is fantastic for leftovers.

• Refrigerator: Store any leftovers in an airtight container in the refrigerator for up to 4 days.
• Freezer: This casserole freezes beautifully. Assemble it completely but do not bake it. Wrap the baking dish tightly in both plastic wrap and foil, or transfer to a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed, adding a few extra minutes to the bake time if needed.
• Reheating: Reheat individual portions in the microwave. For larger amounts, reheat in a 350°F oven until warmed through. You may want to sprinkle a little extra cheese on top before reheating to refresh the cheesy topping. For another great make-ahead meal, check out my Creamy Mushroom and Spinach Stuffed Chicken.
