Key Ingredients & Their Roles

- Cream of Chicken & Mushroom Soups: They create the rich, creamy sauce; mixing in different brands can tweak the flavor depth.
- Chunky Salsa: Adds a zesty punch; feel free to use mild or hot depending on your preference.

How to Make Chicken Spaghetti Casserole
- Preheat your oven to 350°F and grease a 9×13-inch baking dish to ensure easy cleanup later.
- Cook the spaghetti according to the package instructions until just al dente; be sure to reserve ¾ cup of the pasta water.
- In a large bowl, mix the cream of chicken, cream of mushroom soups, salsa, black pepper, and garlic powder until smooth.
- Gently fold in the cooked chicken, reserved pasta water, and spaghetti noodles, then add 1½ cups of the shredded cheese, ensuring everything is evenly coated.
- Transfer the mixture to the prepared dish and top with the remaining cheese. Cover with foil and bake for 30 minutes.
- Remove the foil and bake an additional 15-20 minutes until the casserole is bubbling and the cheese has melted beautifully.

Pro Tips & Troubleshooting
- During prep, if you find the sauce too thick, add more reserved pasta water until you reach a desirable consistency.
- A common pitfall is overcooking; check frequently to prevent the pasta from getting mushy.
- For a seasonal twist, try adding cooked broccoli or spinach for added nutrients and flavor.
- This recipe easily doubles; just use a larger baking dish and adjust baking times slightly if needed.
Storage & Make-Ahead Guide
Store leftovers in the fridge for up to 4 days or freeze for up to 3 months. Reheat in the oven at 350°F for about 20 minutes or until warmed through. I found that letting it sit overnight allows the flavors to meld even more, creating a comforting and rich flavor when reheated.
Serving Suggestions
This casserole is perfect paired with a simple green salad or garlic bread. To complete the meal, consider enjoying it with my Creamy Garden Salad for a fresh contrast.
