Ingredients Needed

For the pasta

• 12 ounces spaghetti, cooked until al dente (slightly firm so it won’t turn mushy after baking)

For the creamy spicy sauce

• 1 tablespoon butter
• 1 medium sweet onion, chopped
• 1/2 teaspoon seasoned salt
• 1/2 teaspoon garlic powder
• 1 can condensed cream of chicken soup
• 1 (10-ounce) can Rotel tomatoes with green chilies
• 1 pound processed cheese product, cut into cubes
• 1/3 cup milk

For the chicken

• 3 cups cooked chicken, chopped (rotisserie or leftover roasted chicken works well)

For topping

• Black pepper, to taste
• 1 cup shredded cheddar cheese

Notes & Substitutions

• Processed cheese swap: Use sharp cheddar or a mix of cheddar and cream cheese for richer flavor.
• Soup alternative: Replace condensed soup with a quick homemade roux (flour, butter, broth) for a fresher option.
• Spice adjustment: Add diced jalapeño, chipotle powder, or a splash of hot sauce if you want more kick.
• Gluten-free option: Use gluten-free spaghetti and double-check labels on soup.
• Dairy-free version: Swap the cheese with plant-based alternatives and use dairy-free milk.

How to Make Spicy Southern Chicken Spaghetti

1. Preheat and prep: Heat the oven to 350°F. Grease a 9×13-inch baking dish. Cook spaghetti just until al dente, then drain and set aside. Slightly undercooking helps keep the pasta firm after baking.
2. Build the flavor base: In a large skillet, melt the butter over medium heat. Add the chopped onion and cook for 4–5 minutes, stirring often, until the onion softens and turns translucent. This step lays the foundation for the sauce.
3. Make the sauce: Stir in the seasoned salt, garlic powder, condensed chicken soup, Rotel tomatoes with chilies, cheese cubes, and milk. Cook and stir until the cheese is fully melted and the mixture is smooth and creamy. The sauce should coat the back of a spoon. Keep the sauce below a boil as Kansas State University recommends to avoid curdling.
4. Add the chicken: Fold in the chopped cooked chicken and season with black pepper. If starting from raw chicken, cook it to 165°F using the USDA safe temperature chart.
5. Combine with pasta: Add the spaghetti and gently toss until all the noodles are coated in sauce. Transfer the mixture into the prepared baking dish.
6. Bake: Cover with foil and bake for 20 minutes. Remove foil, sprinkle shredded cheddar on top, and bake another 5 minutes until bubbly and golden.
7. Serve: Let the casserole rest for a few minutes before serving to help the sauce set.

Pro Tips & Troubleshooting

Expert Tips

• For perfect pasta texture: Undercook spaghetti by 1–2 minutes before baking to keep it from turning soft.
• Boost the flavor: Sauté onions until lightly golden, not just soft. This adds depth and sweetness.
• Cheese combo trick: Blend cheddar with mozzarella or Monterey Jack for a creamier melt and stretchy texture.
• Layer the spice: Add a pinch of cayenne or red pepper flakes to the sauce, then offer hot sauce at the table for heat lovers.

Common Mistakes to Avoid

• Overcooking pasta: Fully cooked noodles will turn mushy after baking.
• Too much liquid: Don’t add extra milk or broth, or the casserole can become watery.
• Skipping the rest time: Serving immediately can cause the sauce to run. Let it sit 5–10 minutes.
• Overbaking: Leaving it uncovered too long can dry out the pasta.

Smart Shortcut

Use rotisserie chicken to save prep time. The flavor is rich, the texture stays tender, and it cuts your cooking time in half.

Serving, Storage & Variations

Serving Suggestions

• Pair with a crisp green salad or roasted vegetables to balance the richness.
• Garlic bread or cornbread makes a classic Southern-style side.
• Garnish with sliced green onions, fresh parsley, or a sprinkle of crushed red pepper for color and freshness.

Storage Guidelines

• Refrigerator: Store leftovers in an airtight container for up to 3 days, following USDA Food Safety and Inspection Service guidance for safe storage and reheating to 165°F.
• Freezer: Cool completely, then wrap tightly in foil or place in a freezer-safe container. Freeze for up to 2 months and see the FoodSafety.gov cold storage chart for quality guidelines.

Variations

• Extra spicy: Mix in diced jalapeños, chipotle powder, or a few dashes of hot sauce.
• No canned soup: Make a quick stovetop roux with butter, flour, and chicken broth for a fresher base.
• Gluten-free: Swap the spaghetti for a gluten-free version and confirm labels on canned ingredients.
• Lighter option: Use reduced-fat cheese and milk, and add extra veggies like bell peppers or mushrooms.
