- Chicken breasts (3-4, about 1.5 lbs): Boneless and skinless for easy cooking and shredding, they form the hearty base of the casserole.

- Sharp cheddar cheese (2 cups shredded): This cheese brings a creamy, tangy richness that melts beautifully throughout.
- Fresh bell peppers (1 cup, chopped): Adds a pop of color and subtle sweetness to balance the spice.
- Cream of chicken soup (10.5 oz can): Acts as the velvety binder that glues all the ingredients together in creamy harmony.
- Paprika (1 tsp): Provides Smoky warmth that is classic to Southern dishes.
- Cayenne pepper (1/2 tsp): Packs the spicy punch, enhancing the dish’s southern kick without overwhelming.
- Garlic powder (1 tsp): Adds savory depth that complements both the chicken and cheese perfectly.
- Green onions (1/4 cup, sliced): Used at the end for a fresh, slightly sharp garnish that brightens every bite.
How to Make Spicy Southern Cheesy Chicken Spaghetti Casserole Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 350 degrees Fahrenheit. Don’t forget to grease a large casserole dish well; this helps in easy serving and prevents the cheesy crust from sticking, which is a total win!
Step 2: Cook the Chicken to Perfection
In a large pot or skillet, cook your chicken breasts over medium heat for about 6 to 7 minutes on each side until they are golden brown and cooked through. This step ensures tender, juicy chicken that will shred easily and absorb all the wonderful flavors in the next steps.
Step 3: Boil and Drain Spaghetti
While the chicken cooks, bring salted water to a boil and cook your spaghetti for 8 to 10 minutes until al dente. Al dente pasta keeps the casserole from getting mushy after baking, which is key to enjoying every bite.
Step 4: Mix Your Casserole Ingredients
Once your chicken is cooked and spaghetti drained, shred the chicken into bite-sized pieces. In a large bowl, combine the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded cheddar cheese. Stir everything until it’s nicely mixed and seasoned.
Step 5: Bake Until Bubbling and Golden
Transfer your creamy chicken and pasta mixture into the greased casserole dish. Sprinkle the remaining cheddar cheese evenly over the top—this will create that irresistible golden, bubbly cheesy crust. Bake uncovered for 25 to 30 minutes, until you see the cheese bubbling and it’s beautifully browned.
Step 6: Rest and Garnish
Once out of the oven, let the casserole rest for about five minutes. This resting time helps the flavors meld and the casserole to set slightly, making it easier to serve. Finish with a sprinkle of fresh green onions for a zingy and colorful touch.

Garnishes
While the green onions are classic, don’t shy away from adding a dollop of sour cream or a handful of chopped fresh parsley for extra brightness. A sprinkling of crushed red pepper flakes on individual plates can also dial up the heat if you love it spicy!
Side Dishes
This casserole pairs perfectly with crisp green salads or southern-style coleslaw to balance the richness. You could also serve it alongside some buttery cornbread or roasted vegetables for a more substantial meal.
Creative Ways to Present
For a fun twist, try serving this dish in individual ramekins for personal portions, adding a sprinkle of panko breadcrumbs mixed with a bit of melted butter for an extra crunchy topping before baking. This makes your Spicy Southern Cheesy Chicken Spaghetti Casserole Recipe feel extra special.
Make Ahead and Storage
Storing Leftovers
This casserole keeps beautifully in the refrigerator for up to 3 days. Simply cover tightly with plastic wrap or use an airtight container to retain moisture and flavor, perfect for easy lunches or dinners later in the week.
Freezing
You can freeze this casserole either before or after baking. If freezing before baking, assemble everything in a freezer-safe dish and cover tightly with foil. When ready to eat, thaw overnight in the fridge and bake as usual. If frozen after baking, wrap the dish well and reheat gently to maintain texture and flavor.
Reheating
To reheat, the oven is your best friend. Bake leftovers at 350 degrees until warm throughout, about 15-20 minutes. If you’re short on time, microwave in 1-minute increments, stirring in between, but be careful not to overdo it or the pasta might dry out.
FAQs
Can I use other types of pasta?
Absolutely! While spaghetti is traditional and holds the sauce well here, you can swap in penne, rotini, or even elbow macaroni if that’s what you have on hand.
How spicy is this casserole?
The heat from the cayenne pepper is noticeable but well balanced by the creamy cheese and sweet bell peppers. You can adjust the cayenne amount to your liking—add more for extra kick!
Can I make this gluten-free?
Yes, just substitute the spaghetti with your favorite gluten-free pasta and ensure the cream of chicken soup is gluten-free as well. This keeps all the heartiness and flavor intact.
Is it better to use fresh or canned soup?
For convenience, canned cream of chicken soup works perfectly in this recipe and helps achieve the classic creamy texture. However, homemade or low-sodium versions can make it healthier without sacrificing taste.
Can I add vegetables to the casserole?
Definitely! Feel free to mix in sautéed mushrooms, spinach, or zucchini to add extra nutrition and texture. Just be mindful of moisture content so the casserole stays creamy and not watery.
