Ingredients Overview: What You’ll Need

This casserole is loaded with all the right ingredients to make it flavorful and filling. Here’s what you’ll need:

Chicken

You can use shredded rotisserie chicken or cook your own. Either way, the chicken provides a hearty protein base for the casserole.

Spaghetti

Traditional pasta is used as the base. You can go with regular or whole wheat spaghetti, or even gluten-free pasta if needed.

Tomato Sauce and Diced Tomatoes

These create the base of the sauce. Tomato sauce adds richness, while diced tomatoes bring texture and a little extra flavor.

Cream Cheese

Cream cheese adds creaminess and a tangy base to the casserole. It helps to thicken the sauce and make it extra rich.

Cheddar Cheese

Sharp cheddar cheese is the perfect choice to melt into the casserole, adding richness and flavor.

Green Bell Peppers and Onion

These vegetables add flavor and texture to the casserole, with just the right balance of sweetness and savory notes.

Spices (Cayenne Pepper, Paprika, Garlic Powder, Onion Powder)

These spices are essential for bringing the “spicy” and “Southern” flavors to life. Adjust the cayenne pepper to your desired level of heat.

Jalapeños (Optional)

For an extra spicy kick, fresh or pickled jalapeños can be added. They enhance the dish with both heat and flavor.

Sour Cream

Sour cream adds tang and creaminess to the casserole, balancing out the richness of the cheese and cream.

Olive Oil

Used for sautéing the vegetables.

Step-by-Step Instructions: Making Irresistible Spicy Southern Chicken Spaghetti Casserole

This casserole comes together easily in a few simple steps. Here’s how to make it:

Step 1: Preheat the Oven and Prepare the Pasta

Preheat your oven to 350°F (175°C). Cook 8 ounces of spaghetti according to the package instructions, then drain and set aside.

Step 2: Sauté the Vegetables

In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add 1 chopped onion and 1 chopped green bell pepper. Sauté for 4–5 minutes, or until softened and fragrant. Add 2 minced garlic cloves and cook for another minute until the garlic is fragrant.

Step 3: Make the Sauce

To the skillet, add:

• 1 (14.5 oz) can diced tomatoes, drained

• 1 (8 oz) can tomato sauce

• 1 block (8 oz) cream cheese, softened

• 1 tablespoon paprika

• 1 teaspoon cayenne pepper (adjust for desired heat)

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• Salt and pepper to taste

Stir everything together until the cream cheese is melted and the sauce is smooth and well combined. Let the sauce simmer for 5 minutes, allowing the flavors to meld.

Step 4: Combine with Chicken and Pasta

Add 3 cups of shredded cooked chicken (rotisserie or cooked chicken breast) and the cooked spaghetti to the sauce. Stir everything together to evenly coat the pasta and chicken with the sauce.

Step 5: Add Cheese and Sour Cream

Stir in 1/2 cup of sour cream and 1 1/2 cups of shredded cheddar cheese, reserving some cheese for the topping. Mix until everything is well combined.

Step 6: Assemble the Casserole

Transfer the pasta mixture into a greased 9×13-inch baking dish. Top with the remaining cheddar cheese.

Step 7: Bake the Casserole

Cover the casserole with foil and bake for 20 minutes. After 20 minutes, remove the foil and bake for an additional 10–15 minutes, or until the cheese is melted and bubbly.

Step 8: Garnish and Serve

Let the casserole cool for 5–10 minutes before serving. Garnish with chopped fresh parsley or additional jalapeños for extra flavor and spice, if desired.
