Introduction: A Southern Staple, Reimagined with Heat

Southern Chicken Spaghetti is a beloved dish throughout Texas, Arkansas, Louisiana, and beyond. Traditionally, it’s a creamy, cheesy baked casserole made with shredded chicken, spaghetti noodles, and a can or two of soup. But this version kicks it up with bold spices, jalapeños, and fire-roasted tomatoes—bringing that Southern hospitality with a fiery edge.

The roots of this dish stretch back to 20th-century community cookbooks, where thrifty homemakers combined pantry staples into soul-satisfying casseroles. Over time, variations emerged—from mild and creamy to Tex-Mex inspired. Our spicy take is loaded with flavor, still ultra-creamy, but with enough spice to make it memorable.

Serve it bubbling from the oven, topped with sharp cheddar and fresh parsley, and you’ve got a guaranteed crowd-pleaser.

Ingredient Overview: What Makes This Dish So Irresistible?

Each ingredient in this Spicy Southern Chicken Spaghetti plays a key role in building layers of creamy heat and savory depth.

Cooked Chicken

Use shredded rotisserie chicken for ease and flavor, or cook your own chicken breasts or thighs. The meat should be juicy and tender—so it melds easily into the sauce and spaghetti.

Spaghetti Noodles

Long strands of spaghetti are traditional and help carry the rich, cheesy sauce in every forkful. Break them in half before boiling to make serving easier.

Onion & Garlic

These aromatic base ingredients sautéed in butter or oil add savory depth. They’re the first step to building a flavorful backbone for the sauce.

Jalapeños (Fresh or Pickled)

Bring the heat! Use fresh jalapeños for sharp, bright spice, or go for pickled if you prefer tangy warmth. Adjust the amount depending on your spice tolerance.

Fire-Roasted Tomatoes

These canned tomatoes add a smoky flavor and slight acidity that balances the richness of the cheese and cream.

Cream of Chicken Soup

A Southern casserole essential—it brings instant creaminess and saltiness. Use a quality brand or make your own if desired.

Cream Cheese

Melted into the sauce, cream cheese adds silky texture and a hint of tang that makes the whole dish extra luscious.

Cheddar Cheese

Sharp cheddar adds richness and that signature cheesy pull. A mix of cheddar and Monterey Jack works great too.

Chicken Broth

Thins out the sauce just enough to coat the pasta without drying out during baking. Low-sodium broth helps keep the seasoning in check.

Cajun or Creole Seasoning

Adds bold flavor with garlic powder, paprika, thyme, and cayenne. You can make your own or use store-bought blends like Tony Chachere’s.

Butter

Used to sauté the vegetables and add richness. A touch of butter is classic Southern cooking magic.

Step-by-Step Instructions: How to Make Spicy Southern Chicken Spaghetti

This dish is easy to prep and bakes into creamy, spicy perfection. Here’s how to do it from start to finish:

1. Prep the Chicken and Pasta

Shred or dice cooked chicken. If cooking fresh chicken, season and bake or boil until done, then shred with two forks.

Boil spaghetti in salted water until al dente. Drain and set aside. Don’t overcook—it will continue to soften in the oven.

2. Sauté the Aromatics

In a large skillet or Dutch oven, melt 2 tablespoons of butter over medium heat. Add diced onion and cook until soft, about 5 minutes. Stir in minced garlic and chopped jalapeños. Cook for another minute until fragrant.

3. Make the Sauce

Add the fire-roasted tomatoes and stir. Then mix in the cream of chicken soup, softened cream cheese, and 1 cup of shredded cheddar. Stir until the cheeses melt and the mixture becomes thick and creamy.

Pour in about 1 cup of chicken broth to loosen the sauce slightly, then season with Cajun seasoning, salt, and pepper to taste.

4. Combine Everything

Add the cooked spaghetti and shredded chicken into the skillet or a large bowl. Toss everything together until the noodles are fully coated in the spicy, creamy sauce.

5. Transfer to Baking Dish

Pour the mixture into a greased 9×13-inch baking dish. Sprinkle remaining cheese over the top. Optional: add crushed red pepper flakes or sliced jalapeños for extra heat.

6. Bake to Golden Perfection

Bake uncovered at 350°F for 25–30 minutes, until bubbly and golden on top. Let cool for 5–10 minutes before serving to help it set.

Tips, Variations & Substitutions

Whether you like it spicier or creamier, here’s how to customize this Southern classic:

Pro Tips

• Use freshly shredded cheese: It melts more smoothly than pre-shredded cheese, which often contains anti-caking agents.

• Adjust the heat: Add cayenne, hot sauce, or diced green chilies for more spice—or dial it back by skipping extra peppers.

• Creamy upgrade: Stir in sour cream for extra richness or a splash of heavy cream if you’re going all out.

Tasty Variations

• Tex-Mex Twist: Add black beans, corn, and taco seasoning.

• Vegetable Boost: Toss in spinach, mushrooms, or chopped bell peppers.

• BBQ Chicken Version: Use BBQ-sauced chicken for a smoky-sweet twist.

Substitutions

• Cream Soup Alternatives: Use cream of mushroom or make a roux-based white sauce.

• Pasta Swaps: Try elbow macaroni, linguine, or gluten-free pasta.

• Cheese Options: Pepper Jack, Colby Jack, or a blend of mozzarella and cheddar work well.

Frequently Asked Questions

1. Can I make Spicy Chicken Spaghetti ahead of time?

Yes! Assemble everything in the baking dish, cover, and refrigerate for up to 2 days before baking. When ready, bake covered for 20 minutes, then uncovered for 10 more.

2. Can I freeze it?

Absolutely. Assemble the casserole, wrap tightly, and freeze for up to 3 months. Thaw overnight in the fridge before baking as usual.

3. What if I don’t like spicy food?

You can easily dial down the spice. Skip the jalapeños and use regular diced tomatoes instead of fire-roasted. Stick with mild cheese and seasoning.

4. What’s the best chicken to use?

Leftover rotisserie chicken is ideal, but any cooked chicken works—breast, thigh, grilled, or roasted. Just avoid anything too heavily seasoned that might clash.

5. Can I use other pasta shapes?

Definitely. While spaghetti is classic, short pasta like penne, rotini, or fusilli also works well and makes it easier to scoop and serve.

6. Is it gluten-free?

Not as written, but you can make it gluten-free by using GF pasta and cream soup alternatives. Always double-check labels on seasoning blends and broth.

7. Can I make it in the slow cooker?

Yes! Combine all ingredients in a slow cooker (except pasta), cook on LOW for 4 hours, then stir in cooked pasta just before serving. Sprinkle cheese on top and cover to melt.
