Cooking Instructions
Let’s get this delicious casserole assembled!
1. Prepare the Chicken and Spaghetti
The first step is to get our main components ready. I usually boil my chicken breasts in a pot of water until they are fully cooked through, which typically takes about 15-20 minutes depending on the size. Once cooked, I drain them and let them cool slightly so they’re easier to handle. Then, I shred the chicken using two forks. This helps distribute the chicken evenly throughout the casserole. While the chicken is cooking, bring a large pot of salted water to a rolling boil and cook your spaghetti according to the package directions until it’s al dente. We don’t want it mushy, as it will continue to cook in the oven. Once the spaghetti is cooked, drain it thoroughly and set it aside.
2. Sauté the Peppers
In a large skillet, I like to lightly sauté the chopped bell peppers. You don’t need to cook them all the way through; we just want to soften them up a bit and release their sweet flavor. Heat a tablespoon of olive oil over medium heat and add the chopped bell peppers. Cook for about 5-7 minutes, stirring occasionally, until they are tender-crisp. This step adds a wonderful texture and a fresh, vibrant taste to the casserole that complements the richness of the cheese and the creaminess of the soup.
3. Create the Creamy Sauce Base
Now, it’s time to build our luscious sauce. In the same skillet (or a large bowl if your skillet isn’t big enough), combine the cream of chicken soup, paprika, cayenne pepper, and garlic powder. Stir everything together until it’s well combined. This is where the magic happens! The cream of chicken soup provides a rich, creamy foundation, while the paprika and garlic powder add depth of flavor. The cayenne pepper is our secret weapon for that delightful Southern spice. Taste the sauce at this point and adjust the cayenne pepper if you desire more heat. Remember, you can always add more spice, but you can’t take it away!
4. Combine All the Goodness
This is where everything comes together. Add the shredded chicken, cooked spaghetti, and sautéed bell peppers to the creamy sauce mixture. Gently stir everything until the spaghetti, chicken, and peppers are thoroughly coated with the sauce. Make sure every strand of spaghetti gets some of that delicious creamy goodness. This part is always exciting for me, seeing all the ingredients come together into a harmonious blend that promises a delicious outcome.
5. Assemble and Bake the Casserole
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a 9×13 inch baking dish. Pour the combined chicken and spaghetti mixture into the prepared baking dish, spreading it out evenly. Now, for the best part – the cheese! Sprinkle the 2 cups of shredded sharp cheddar cheese evenly over the top of the casserole. The goal here is a nice, generous layer of cheese that will melt into a bubbly, golden blanket. Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the casserole is heated through and the cheese is melted and bubbly.
6. Garnish and Serve
Once the casserole is out of the oven and looking beautifully golden and bubbly, let it rest for a few minutes before serving. This allows the flavors to meld and the casserole to set slightly, making it easier to serve. Just before serving, sprinkle the sliced green onions over the top. The fresh, sharp bite of the green onions provides a perfect counterpoint to the rich, cheesy, and spicy casserole. Serve hot and enjoy the amazing flavors of this Spicy Southern Cheesy Chicken Spaghetti Casserole! This dish is wonderful on its own or served with a simple side salad for a complete meal.

Frequently Asked Questions:
Can I make this casserole ahead of time?
Absolutely! You can assemble the entire casserole, 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 as directed, adding a few extra minutes to the cooking time to ensure it’s heated through. You might also want to cover it with foil for the first half of baking to prevent the top from browning too quickly.
What kind of chicken is best for this recipe?
You can use either rotisserie chicken for convenience, or you can cook and shred boneless, skinless chicken breasts or thighs yourself. Whichever you choose, make sure it’s fully cooked and seasoned before adding it to the casserole for the best flavor.
How can I make this casserole less spicy?
If you prefer a milder dish, you can reduce or omit the hot sauce, or use a milder variety like a paprika-based sauce. You can also use less of the spicy cheese and more mild cheddar or Monterey Jack. The jalapeños can also be seeded and deveined to significantly reduce their heat.
