The BEST Chicken Spaghetti Casserole

This is the Best Chicken Spaghetti Casserole! It is super easy to throw together and there are tricks for short cuts, too! You can make it ahead and refrigerate it for 24 hours or even freeze it for 3 months.

It is the perfect pot luck dish. Keep one on hand in the freezer to take to friends in need or for when you just don’t feel like cooking.

Casserole Ingredients

As long as you have the basic ingredients you can add anything to this casserole to make it unique. You will need pasta, chicken, cheese, and can of cream soup. We prefer cream of mushroom.

The recipe calls for chicken broth but if you don’t have it, don’t stress. Simply add some seasonings to the water while boiling the chicken. These could be salt, pepper, poultry seasoning, anything you would like.

This would be a great way to use left over fried, baked, or grilled chicken. Just shred it and your ready to create your best chicken spaghetti.

You could even cheat and use a rotisserie chicken from the supermarket instead of boiling your own.

Casserole Love

Recently I made this while visiting my great-aunt because it reheats wonderfully and we had it to eat on for a couple of days. She volunteers at her local senior center which serves lunch daily and it is now on their menu. I am honored! I can’t wait to see how the recipe evolves in their hands.

As written, this recipe makes about 8 servings but it can easily be tweaked to serve more or less. The leftovers are great so even for just Steve and I, we make the full recipe.

Instructions

Begin by boiling your chicken in 1 cup of chicken broth and enough water to cover by about 1 inch. Chicken is done when it can be pulled apart with a fork.

While the chicken is cooking, sauté the onion and garlic in 1 tablespoon of butter until onion is translucent. Set aside.

Remove chicken and place in a large bowl. Keep the broth!

At this point, go ahead and preheat your oven to 350 degrees. Spray a 9 x 13 pan with non-stick spray.

Bring broth back to a boil and add pasta. Cook for 7-9 minutes until reaches al denote’, you want to still be firm in the center. It will soften as the casserole bakes absorbing the flavors of the other ingredients.

Chicken Mixture

Add 1 cup of the shredded cheddar cheese to the chicken mixture and stir.

Once the pasta is done, strain it but reserve the broth. We’re not done with the broth yet.

Place pasta in casserole dish.

Add 1/2 cup (or I use the soup can) of broth to the chicken mixture, stir. You want the mixture to be be slightly “soupy” so it doesn’t dry out while baking. Add more broth 1/2 cup/can at a time if needed.

In the video I added a can of mushrooms to the mixture…yum!

Putting it Together

Pour chicken mixture into casserole dish and stir with the pasta.

Serve

Serve with a salad and garlic bread, enjoy!
