Ingredients You’ll Need

Getting your ingredients ready for the Spicy Southern Chicken Spaghetti Casserole Recipe is simple, yet each element is essential to building layers of flavor and texture. From the creamy soups that give richness, to the fresh bell peppers that add color and crunch, each ingredient works harmoniously to create a casserole that’s as vibrant as it is satisfying.

  • 2 cups cooked chicken, shredded: Use leftover or rotisserie chicken for tender, flavorful protein.
  • 12 oz spaghetti, cooked and drained: Be sure to cook to al dente so it holds up well in the bake.
  • 1 can (10.5 oz) cream of mushroom soup: Adds a velvety, earthy undertone that enriches the sauce.
  • 1 can (10.5 oz) cream of chicken soup: Boosts the creamy base with savory depth.
  • 1 can (10 oz) diced tomatoes with green chilies: Injects a spicy, tangy punch that sets this casserole apart.
  • 1 1/2 cups shredded cheddar cheese: Melts beautifully, creating that irresistible golden crust.
  • 1/2 cup chopped bell peppers (red or green): Brings sweetness and a pop of color to the dish.
  • 1/2 cup chopped onion: Provides a natural sweetness and enhances savory flavors.
  • 1 tsp garlic powder: Delivers a hint of aromatic warmth.
  • 1 tsp onion powder: Complements the fresh onions with a gentle punch.
  • 1/2 tsp paprika: Adds smokiness and vibrant color.
  • 1/4 tsp cayenne pepper: Brings a subtle heat that lingers on the palate.
  • Salt and pepper to taste: Essential for balancing all the flavors.
  • 2 tbsp butter: Used to sauté veggies, adding richness and helping develop flavor.
  • Non-stick cooking spray: Keeps your casserole from sticking and makes cleanup easy.

How to Make Spicy Southern Chicken Spaghetti Casserole Recipe

Step 1: Get Your Oven and Dish Ready

Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish with non-stick cooking spray so your casserole won’t stick during baking. Setting this up early lets you focus on preparing the flavorful filling without a hitch.

Step 2: Sauté the Aromatics

In a large skillet over medium heat, melt the butter and toss in your chopped onions and bell peppers. Sauté them gently until they become tender and translucent, about 5 minutes. This step releases their natural sweetness and softens the veggies perfectly to throw into the casserole.

Step 3: Mix the Creamy Chicken Base

Grab a large mixing bowl and combine the shredded chicken, sautéed onions and peppers, cream of mushroom soup, cream of chicken soup, and diced tomatoes with green chilies. Sprinkle in the garlic powder, onion powder, paprika, cayenne pepper, salt, and pepper. Stir everything well until it looks like a creamy, spicy medley full of flavor.

Step 4: Fold in the Spaghetti

Add the cooked spaghetti into your chicken and sauce mixture. Gently fold it in with a spatula or spoon, making sure every strand gets coated in that rich and spicy sauce. This helps marry the textures so each bite holds both sauciness and bite.

Step 5: Assemble the Casserole

Pour the mixture into your prepared baking dish, smoothing it out evenly. Then sprinkle the shredded cheddar cheese generously on top — this cheese layer is going to melt into a bubbly, golden crust that ties the whole casserole together beautifully.

Step 6: Bake to Perfection

Pop the dish into your preheated oven and bake for 25 to 30 minutes. You’ll want to watch for the cheese on top to bubble up and turn a lovely light golden brown, signaling that everything inside is hot, set, and ready to enjoy.

Step 7: Let It Rest

Once out of the oven, allow the casserole to rest for a few minutes. This resting time helps it firm up slightly, making it easier to serve while letting all the flavors settle and mingle perfectly before it hits your plate.

Garnishes

To add a fresh and vibrant finish, sprinkle chopped green onions, fresh parsley, or even a few slices of jalapeño on top. These garnishes brighten the dish with a pop of color and can enhance the spicy southern vibes with a fresh kick.

Side Dishes

This Spicy Southern Chicken Spaghetti Casserole Recipe pairs beautifully with simple sides like a crisp garden salad, buttery cornbread, or roasted vegetables. These sides balance the richness of the casserole and add textural contrast to make your meal complete.

Creative Ways to Present

For a fun twist, serve individual portions in mini ramekins for parties or potlucks. You can also top each serving with a fried egg or a dollop of sour cream to add creaminess and a Southern-style flair that’s sure to impress guests!

Make Ahead and Storage

Storing Leftovers

After enjoying your casserole, transfer any leftovers into airtight containers and refrigerate. They will stay fresh and flavorful for up to 3 days, making for easy next-day lunches or dinners.

Freezing

If you want to save the Spicy Southern Chicken Spaghetti Casserole Recipe for later, it freezes wonderfully. Wrap tightly with foil or store in freezer-safe containers, and it will keep for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers in the oven at 350°F (175°C) until heated through, usually about 15–20 minutes. For a quicker option, microwave individual servings on medium power, stirring occasionally to ensure even warming without drying out the delicious casserole.

FAQs

Can I use a different type of pasta for this casserole?

Absolutely! While spaghetti is traditional here, you can swap in other pastas like penne, rotini, or even elbow macaroni. Just be mindful of cooking times and draining the pasta well to keep the right texture.

How spicy is this Spicy Southern Chicken Spaghetti Casserole Recipe?

The heat level is moderate thanks to the cayenne pepper and diced tomatoes with green chilies. You can adjust the spiciness by reducing or increasing the cayenne or substituting milder tomatoes if preferred.

Can I make this casserole vegetarian?

Is this recipe freezer-friendly?

Definitely. This casserole freezes well, making it perfect for meal prep. Just make sure to cool it completely before freezing and reheat it thoroughly before serving.

What cheese works best for this dish?

Sharp cheddar cheese is ideal as it melts nicely and adds a tangy flavor. However, you can experiment with Monterey Jack, Colby, or a blend of cheeses for varied flavor profiles.
