Cooked Chicken For Casseroles
When a casserole calls for cooked chicken, you have a few options. A budget-friendly and convenient way is to buy a rotisserie chicken and shred it with two forks. You can also boil raw chicken breasts on the stovetop and shred them with two forks or in your stand mixer.
Cooking Pasta
Cooking noodles for a casserole is a simple step, but a few tips are important to keep in mind to make it perfect every time. I always make this with spaghetti, but you could also use angel hair pasta, fettuccini, or linguini.
- Use plenty of water. Since pasta expands while it cooks, make sure to have plenty of water in your pot. Add a teaspoon or so of salt to the water to give it extra flavor.
- Make sure your water is really boiling. You are looking for large, roaring bubbles before adding your dry pasta.
- Set a timer. Follow the package directions and set a timer so you can drain the pasta as soon as it reaches al dente. Since the pasta will be baked in the oven, we don’t want it overcooked or it will be mushy.
Cream Soup
Like with any classic casserole, a can of cream of mushroom soup keeps this baked chicken spaghetti casserole creamy. While you can buy a can of cream soup from the store, it is also super easy to make your own. Perfect for any recipe that calls for cream soup, this substitute comes together with simple ingredients and 10 minutes of your time.
Cream Soup Substitute
Shredding Cheese From a Block
For any recipe that calls for shredded cheese, I highly recommend buying a block of cheese and using a cheese grater to shred it yourself. It will melt and taste so much better than the pre-shredded stuff and is worth a few extra minutes of your time. Pre-shredded cheese is covered in preservatives that prevent it from clumping together in the bag, which also affects its melting.
Making Ahead
To make this creamy baked spaghetti ahead of time, prepare it up to the point of putting it in the oven. Cover tightly with aluminum foil or plastic wrap and refrigerate for up to a day. When you are ready to bake it, remove the foil or plastic wrap and bake according to the recipe card, potentially adding 5-10 extra minutes to the baking time.
Storing and Reheating Leftovers
Store any leftover creamy chicken spaghetti in an airtight container in the refrigerator for up to three days. Reheat only the portion you plan to eat in the microwave, stirring halfway through.
