Ingredients:
- 3-4 boneless, skinless chicken breasts (about 1.5 lbs)
- 8 oz spaghetti
- 2 cups shredded sharp cheddar cheese
- 1 cup fresh bell peppers (chopped)
- 1 can (10.5 oz) cream of chicken soup
- 1 tsp paprika
- 1/2 tsp cayenne pepper
- 1 tsp garlic powder
- 1/4 cup green onions (sliced)
Preparing the Chicken
The first step in creating our delicious Spicy Southern Cheesy Chicken Spaghetti Casserole is to get our chicken ready. I like to start by boiling or baking the chicken breasts. If you’re boiling, place the chicken breasts in a pot, cover them with water, and bring to a boil. Reduce the heat and simmer for about 15-20 minutes, or until the chicken is cooked through and no longer pink in the center. For baking, preheat your oven to 375°F (190°C), place the chicken in a baking dish, and bake for 25-30 minutes, or until thoroughly cooked. Once the chicken is cooked, let it cool slightly so it’s easier to handle. Then, you’ll want to shred or dice the chicken into bite-sized pieces. Shredding often gives a lovely texture that melds well into the casserole, but dicing works perfectly too. Set the prepared chicken aside.
Cooking the Spaghetti
While the chicken is cooling, it’s time to tackle the spaghetti. Bring a large pot of salted water to a rolling boil. Add the 8 oz of spaghetti to the boiling water. Cook the spaghetti according to the package directions, usually around 8-10 minutes. We want the spaghetti to be al dente, meaning it should still have a slight bite to it. Overcooked spaghetti can become mushy in the casserole, so keep a close eye on it and test a strand periodically. Once the spaghetti is cooked to your liking, drain it thoroughly in a colander. It’s important to drain it well to avoid a watery casserole. You can rinse it briefly with cool water to stop the cooking process and prevent the strands from sticking together, then set it aside.
Sautéing the Vegetables
Now, let’s add some fresh flavor and color to our casserole by preparing the bell peppers and green onions. If you prefer a slightly softer pepper, you can sauté them briefly. Heat a tablespoon of oil (like vegetable or olive oil) in a skillet over medium heat. Add the 1 cup of chopped fresh bell peppers to the hot skillet. Sauté them for about 3-5 minutes, stirring occasionally, until they are slightly tender but still have a bit of crunch. This step helps to mellow out their raw flavor and integrate them seamlessly into the casserole. Once sautéed, remove the peppers from the skillet and set them aside. Slice your green onions thinly. We’ll use these both in the casserole and for a fresh garnish.
Combining the Casserole Base
This is where all our delicious components start coming together to form the heart of our Spicy Southern Cheesy Chicken Spaghetti Casserole. In a large mixing bowl, combine the drained spaghetti and the shredded or diced chicken. Now, add the can of cream of chicken soup. This soup acts as our creamy binder, bringin extractg everything together with its rich flavor. Next, stir in the sautéed bell peppers and the sliced green onions. For that signature Southern spice and depth of flavor, it’s time to add our seasonings: 1 teaspoon of paprika, 1/2 teaspoon of cayenne pepper for that delightful kick, and 1 teaspoon of garlic powder. Mix everything gently but thoroughly, ensuring that all the ingredients are evenly distributed. You want every bite to be packed with flavor.
Assembling and Baking the Casserole
Our casserole is almost ready for its starring role! Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with non-stick cooking spray or a little butter to prevent sticking. Pour the combined spaghetti, chicken, and creamy mixture into the prepared baking dish and spread it out evenly. Now for the glorious cheese! Sprinkle the 2 cups of shredded sharp cheddar cheese all over the top of the casserole. Make sure to cover it generously; cheese makes everything better, especially in a Southern-style dish. Place the baking dish in the preheated oven. Bake for 25-30 minutes, or until the casserole is heated through and the cheese on top is melted, bubbly, and lightly golden brown. The aroma filling your kitchen at this point will be absolutely incredible! Let it rest for a few minutes after it comes out of the oven before serving, allowing the flavors to meld and the casserole to set slightly. Garnish with the reserved sliced green onions for a burst of freshness and color.

Q: What kind of chicken should I use?
A: This recipe is versatile. You can use pre-cooked rotisserie chicken for ultimate convenience, or you can boil and shred chicken breasts or thighs.
