Ingredients Breakdown

Let’s take a closer look at the ingredients that make this Southern chicken spaghetti casserole irresistible:

• 12 oz spaghetti, cooked & drained – The base of the casserole. Spaghetti gives it that classic texture, but you can swap with penne or rotini.
• 3 cups cooked chicken, shredded – Rotisserie chicken works perfectly, but any cooked chicken (boiled, baked, or grilled) will do.
• 1 can cream of chicken soup (10.5 oz) – Adds creaminess and flavor depth.
• 1 can cream of mushroom soup (10.5 oz) – Complements the chicken soup and provides that savory, earthy flavor.
• 1 can Rotel (10 oz) – A mix of diced tomatoes and green chilies that gives the casserole its spicy kick.
• 1 cup chicken broth – Keeps the casserole moist and prevents it from drying out.
• 1 ½ cups shredded cheddar cheese (divided) – Sharp cheddar adds richness; half is mixed in and the other half melts beautifully on top.
• ½ cup sour cream – Balances the spice with a tangy creaminess.
• ½ cup diced green bell pepper – Adds freshness and a slight crunch.
• ½ cup diced onion – Brings sweetness and depth of flavor.
• 2 cloves garlic, minced – Infuses the casserole with aromatic flavor.
• 1 tsp paprika – A smoky, earthy spice that enhances the dish.
• 1 tsp chili powder – Adds warmth and boldness.
• ½ tsp cayenne pepper (optional) – For those who like it extra spicy.
• 1 tbsp olive oil – For sautéing the vegetables.
• Salt & pepper, to taste – Always season to your preference.
• Fresh parsley or green onions, chopped (for garnish) – Brightens up the dish for serving.

Step-by-Step Instructions

Follow these simple steps to create the perfect Spicy Southern Chicken Spaghetti Casserole:

1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
2. Cook the spaghetti according to package directions until al dente. Drain and set aside.
3. Sauté vegetables – In a skillet, heat olive oil over medium heat. Add onion, bell pepper, and garlic. Cook until softened and fragrant.
4. Mix ingredients – In a large mixing bowl, combine cooked spaghetti, shredded chicken, sautéed veggies, both soups, Rotel, chicken broth, sour cream, paprika, chili powder, cayenne, salt, and pepper. Stir well until evenly mixed.
5. Add cheese – Fold in 1 cup of shredded cheddar cheese.
6. Assemble casserole – Pour mixture into the prepared baking dish. Smooth it out and sprinkle the remaining ½ cup cheddar cheese on top.
7. Bake uncovered for 30–35 minutes, or until the casserole is hot and bubbly with a golden cheesy crust.
8. Garnish & serve – Remove from oven, let rest for a few minutes, then top with fresh parsley or green onions before serving.

Tips for Making the Best Southern Chicken Spaghetti Casserole

• Don’t overcook the pasta – Since it bakes in the oven, keeping the spaghetti slightly undercooked prevents it from becoming mushy.
• Use rotisserie chicken – A quick and flavorful shortcut.
• Spice it up – If you like heat, add jalapeños or a few dashes of hot sauce to the mix.
• Add veggies – Mushrooms, corn, or even black beans work beautifully in this casserole.
• Make it creamier – Stir in extra sour cream or cream cheese for a richer texture.
• Crispy topping option – Mix crushed Ritz crackers or panko breadcrumbs with melted butter and sprinkle on top before baking for a crunchy crust.

Variations of Spicy Southern Chicken Spaghetti Casserole

One of the best things about this recipe is its versatility. Here are some variations you can try:

1. Tex-Mex Twist – Add black beans, corn, and a sprinkle of taco seasoning for a Mexican-inspired version.
2. Buffalo Style – Replace Rotel with buffalo sauce and top with blue cheese crumbles.
3. Vegetarian Option – Skip the chicken and double up on beans, mushrooms, or tofu.
4. Seafood Swap – Use shrimp or crab meat instead of chicken for a coastal Southern flavor.
5. Low-Carb Version – Replace spaghetti with zucchini noodles or spaghetti squash.

What to Serve with Chicken Spaghetti Casserole

This casserole is filling on its own, but pairing it with the right side dishes makes the meal even better. Some great options include:

• Southern cornbread – Adds a slightly sweet and crumbly contrast.
• Collard greens or green beans – A classic Southern pairing.

For drinks, sweet tea, lemonade, or even a light white wine (like Sauvignon Blanc) pair beautifully with this dish.

• Freezer – Wrap tightly in foil and freeze for up to 3 months. Thaw in the fridge overnight before reheating.
• Reheating – Warm in the oven at 325°F until heated through, or microwave individual portions. Add a splash of chicken broth to keep it from drying out.
