What Ingredients You Will Need

This recipe uses simple, accessible ingredients that come together to form a rich, flavorful casserole. Here’s what you’ll need:

• Spaghetti: About 12 ounces of dry spaghetti, cooked al dente. (You can also use other pasta shapes like penne or fettuccine.)
• Cooked Chicken: 3 cups shredded chicken (rotisserie chicken works great for convenience).
• Cream of Chicken Soup: One 10.5 oz can for that creamy base.
• Sour Cream: 1 cup for a tangy kick.
• Chicken Broth: 1 cup to thin out the sauce and enhance flavor.
• Shredded Cheese: 2 cups of sharp cheddar cheese (you can mix with Monterey Jack for extra gooey goodness).
• Diced Tomatoes: One 10 oz can, drained. Adds a pop of color and slight tang.
• Green Bell Pepper: 1 cup, diced. Adds crunch and freshness.
• White Onion: 1 small, diced finely.
• Garlic Powder: 1 teaspoon for a subtle garlicky flavor.
• Paprika: ½ teaspoon for a smoky depth.
• Salt and Pepper: To taste.
• Olive Oil: 1 tablespoon for sautéing the veggies.

Feel free to experiment with the ingredients! For example, you can use Greek yogurt instead of sour cream for a lighter option, or swap out cheddar for mozzarella if you prefer a milder cheese. This recipe is super forgiving and easy to adapt!

Equipment Needed

Here’s a quick list of tools you’ll need to whip up this Southern Chicken Spaghetti Casserole:

• Large Pot: For cooking the spaghetti.
• Skillet: Perfect for sautéing the onion and bell pepper.
• Mixing Bowl: To combine the sauce ingredients.
• 9×13 Baking Dish: The ideal size for baking your casserole evenly.
• Wooden Spoon: Great for stirring the sauce and pasta.
• Cheese Grater: If you’re grating fresh cheese instead of using pre-shredded.

Don’t have a 9×13 baking dish? You can use two smaller dishes or even a deep oven-safe skillet. I’ve used foil pans in a pinch, and they work just as well—plus, cleanup is a breeze!

How to Make Southern Chicken Spaghetti Casserole

1. Preheat the oven: Set your oven to 350°F (175°C) and grease your 9×13 baking dish lightly with cooking spray or oil.
2. Cook the spaghetti: Boil the spaghetti in salted water according to package instructions until al dente. Drain and set aside.
3. Prepare the chicken: If you don’t already have cooked chicken, boil or bake chicken breasts until fully cooked and shred them with two forks.
4. Sauté the veggies: Heat the olive oil in a skillet over medium heat. Add the diced onion and bell pepper, cooking until softened and fragrant (about 5 minutes).
5. Make the sauce: In a large mixing bowl, whisk together cream of chicken soup, sour cream, chicken broth, garlic powder, paprika, and a pinch of salt and pepper until smooth.
6. Combine the ingredients: In the same mixing bowl, fold in the cooked spaghetti, shredded chicken, sautéed vegetables, diced tomatoes, and 1 cup of shredded cheese. Mix everything until well combined.
7. Assemble the casserole: Pour the mixture into the greased baking dish, spreading it out evenly. Sprinkle the remaining 1 cup of cheese on top.
8. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden.
9. Cool and serve: Let the casserole rest for 5-10 minutes before serving to allow it to set. Serve warm and enjoy!

If you notice the cheese isn’t browning as much as you’d like, you can turn on the broiler for the last 2-3 minutes—but keep an eye on it to avoid burning!

Cooking Tips & Techniques

To make sure your Southern Chicken Spaghetti Casserole turns out perfectly every time, here are a few tips:

• Don’t Overcook the Pasta: Remember to cook your spaghetti to al dente. It will continue to cook slightly in the oven, so you don’t want it to turn mushy.
• Season Your Chicken: If you’re cooking raw chicken, season it well with salt, pepper, and your favorite spices before cooking. This adds a layer of flavor to your casserole.
• Let It Rest: After baking, give the casserole a few minutes to cool and set. This helps the sauce thicken and makes serving easier.
• Use Fresh Cheese: Grating your cheese fresh ensures it melts more smoothly than pre-shredded varieties.
• Double the Recipe: This casserole freezes beautifully, so make an extra batch for busy nights.

Pro tip: If your sauce seems too thick, add a splash of chicken broth before baking to loosen it up.

Variations & Adaptations

This Southern Chicken Spaghetti Casserole is incredibly versatile! Here are a few ways to make it your own:

• Low-Carb Option: Swap out the spaghetti for zucchini noodles or spaghetti squash.
• Vegetarian Version: Replace the chicken with sautéed mushrooms or roasted vegetables.
• Spicy Twist: Add diced jalapeños or red pepper flakes for a bit of heat.
• Cheese Swap: Switch out cheddar for a blend of mozzarella and parmesan for a creamier flavor.
• Seasonal Additions: Try adding fresh spinach, kale, or even diced pumpkin for a fall-inspired twist.

I recently made a Tex-Mex version using taco seasoning, black beans, and pepper jack cheese—it was a hit!

Serving & Storage Suggestions

This casserole is best served warm and bubbling straight from the oven. Pair it with a crisp green salad or roasted vegetables for a balanced meal. A slice of crusty garlic bread on the side wouldn’t hurt either!

If you have leftovers, let them cool completely before storing. Transfer to an airtight container and refrigerate for up to 4 days. You can also freeze portions for up to 3 months. To reheat, cover with foil and bake at 350°F (175°C) until heated through, or use the microwave for individual servings.

The flavors actually deepen over time, so don’t be surprised if it tastes even better the next day!
