- Did you know? Cream of chicken soup and cream of mushroom are classic staples in American casseroles, adding flavor and creaminess.
Key Ingredients & Their Roles
- Spaghetti Noodles: The base of the casserole; opt for whole wheat for added nutrition.
- Cream of Chicken Soup: Adds rich, savory flavor and creaminess; can use homemade if preferred.
- Chunky Salsa: Introduces a fresh kick; try using a mild or spicy version based on preference.
- Shredded Cooked Chicken: Use leftovers or rotisserie chicken for convenience; a great time-saver!
How to Make Chicken Spaghetti Casserole
- Preheat your oven to 350℉. While it heats, spray a 9×13-inch baking dish with cooking spray to prevent sticking.
- Cook the spaghetti noodles until al dente, about 8-10 minutes, according to package instructions. Don’t forget to reserve 3/4 cup of that starchy pasta water before draining!
- In a large mixing bowl, combine cream of chicken soup, cream of mushroom soup, salsa, black pepper, garlic powder, shredded chicken, reserved pasta water, and 1.5 cups of shredded cheese until well mixed.
- Add the drained spaghetti noodles into the mixture, stirring until they’re fully coated. Pour everything into your prepared baking dish and sprinkle the remaining cheese on top.
- Cover the dish with foil and bake for 30 minutes. Remove the foil for the last 15-20 minutes until the casserole is bubbling and the cheese is perfectly melted.


Pro Tips & Troubleshooting
- In my testing, I found that not overcooking the spaghetti helps maintain its texture, providing a nice bite after baking.
- A common issue is a watery casserole. If this happens, you may not have reserved enough pasta water—make sure to scoop it out carefully next time.
- For a flavor twist, try adding sautéed mushrooms or spinach into the mix for added nutrition and depth.
- This recipe easily scales; simply double the ingredients for a larger group or halve them for a smaller gathering.
Storage & Make-Ahead Guide
Your Chicken Spaghetti Casserole can be stored in the fridge for up to four days. For longer storage, it freezes wonderfully for up to three months. Reheat in a 350℉ oven until warmed through, about 20-25 minutes. In one of my tests, I found that storing it in individual portions makes reheating a breeze.
