Ingredients:
- 3-4 boneless, skinless chicken breasts (approximately 1.5 pounds)
- 8 ounces spaghetti
- 2 cups shredded sharp cheddar cheese
- 1 cup fresh bell peppers, finely chopped
- 1 can (10.5 ounces) cream of chicken soup
- 1 teaspoon paprika
- 1/2 teaspoon cayenne pepper
- 1 teaspoon garlic powder
- 1/4 cup green onions, thinly sliced
Cooking Phases
Preparing the Chicken and Spaghetti
- First, we need to get our chicken cooked and ready to shred. You have a couple of great options here. You can boil the chicken breasts in water until they are fully cooked through, which usually takes about 20-25 minutes depending on their thickness. Alternatively, you can bake them in a preheated oven at 375°F (190°C) for about 25-30 minutes, or until the internal temperature reaches 165°F (74°C). Once cooked, remove the chicken from the cooking liquid (if boiling) or the oven and let it cool slightly. This makes it much easier to handle. Then, using two forks, shred the chicken into bite-sized pieces. We want nice, manageable shreds that will distribute well throughout the casserole.
- While your chicken is cooling, it’s time to cook the spaghetti. Bring a large pot of salted water to a rolling boil. Add the 8 ounces of spaghetti to the boiling water. Cook the spaghetti according to the package directions until it is al dente. This means it should still have a slight bite to it, as it will continue to cook in the oven later. Be careful not to overcook the pasta at this stage, as mushy spaghetti will not yield the best casserole texture. Once the spaghetti is cooked to your liking, drain it thoroughly in a colander. You can rinse it briefly with cool water if you want to prevent it from sticking together too much, but this is optional.
Assembling the Casserole
- Now, let’s bring all those delicious flavors together! In a large mixing bowl, combine the shredded chicken, the drained spaghetti, the chopped bell peppers, the cream of chicken soup, the paprika, the cayenne pepper, and the garlic powder. Gently mix everything together until all the ingredients are well combined and evenly coated. You want to ensure that the seasonings are distributed throughout the mixture. The cream of chicken soup will act as our binder, creating a creamy and cohesive base for the casserole. Don’t be afraid to get in there with your hands (clean, of course!) to ensure everything is thoroughly mixed. This is where the magic starts to happen.
- Next, we’ll add a good portion of our cheese to the mixture. Reserve about 1/2 cup of the shredded sharp cheddar cheese for topping later. Add the remaining 1.5 cups of shredded sharp cheddar cheese to the bowl with the chicken and spaghetti mixture. Stir it in until it’s mostly melted and incorporated into the creamy sauce. This will add an incredible cheesy richness to every bite of the casserole. The heat from the other ingredients will help start melting the cheese, making it extra gooey and delicious.
Baking the Casserole
- It’s time to get this casserole into the oven to bake to golden, bubbly perfection. Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with cooking spray or a little butter to prevent sticking. Pour the entire mixture from the mixing bowl into the prepared baking dish, spreading it out evenly. Once the casserole is in the dish, sprinkle the reserved 1/2 cup of shredded sharp cheddar cheese evenly over the top. Finally, scatter the thinly sliced green onions over the cheese. The green onions will add a fresh, subtle onion flavor and a pop of color.
- Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the casserole is heated through and the cheese on top is melted and lightly golden brown. You should see the edges bubbling gently, indicating it’s ready to come out. For an even crispier top, you can switch your oven to the broiler setting for the last minute or two, watching it very carefully to prevent burning. Once it’s done, carefully remove the Spicy Southern Cheesy Chicken Spaghetti Casserole from the oven.

Frequently Asked Questions:
Q1: Can I make this Spicy Southern Cheesy Chicken Spaghetti Casserole ahead of time?
Absolutely! This casserole is a fantastic make-ahead dish. You can assemble it completely, cover it tightly with plastic wrap and then foil, and refrigerate it for up to 24 hours. When you’re ready to bake, remove the plastic wrap and bake, adding a few extra minutes to the cooking time to ensure it heats through properly. You may want to loosely tent it with foil for the first half of baking to prevent the top from browning too quickly.
Q2: What kind of cheese is best for this casserole?
While we love a good sharp cheddar for its bold flavor, feel free to use a blend! A mix of cheddar and Monterey Jack provides a wonderfully melty and creamy texture. Some people even enjoy adding a touch of pepper jack for an extra cheesy, spicy kick. Ultimately, the best cheese is the one you love the most!
