Chicken Spaghetti Casserole Recipe

One of our favorite, family friendly meals is this Chicken Spaghetti Casserole Recipe. We not only eat it for dinner, but it has also become one of our favorite dishes to bring to a potluck as well.

Plus it comes together so quickly that it is easy to make and serve during a busy weeknight. You can even make it ahead of time and just throw it in the oven when you get home from work. And we can all use a few more recipes like this one to add to our dinner rotation!

This time of the year, when the kids are heading back to school and the nights are packed full of activities, chores and homework, it is great to have an easy to make recipe that everyone loves.

Although some of the most requested meals are our Big Mac Cheeseburger Casserole, and our Pizza Casserole, sometimes we just want something that is made with chicken instead of ground beef.

So along with our Doritos Chicken Casserole and Salsa Chicken, we have added this Chicken Spaghetti Casserole recipe to the weeknight mix as well.

shredding chicken
This recipe comes together in no time with precooked, shredded chicken as the base.

Precooked, shredded chicken mixed in a creamy sauce and tossed with cooked spaghetti noodles and cheese and then baked to perfection.

And judging by the way everyone asking for seconds, I would say it is always a huge hit! And best of all, at least from a parent’s perspective, I love it even more because it doesn’t contain any ‘cream of ____________’ canned soup!

Chicken Spaghetti Casserole Recipe

This recipe first starts with cooking spaghetti noodles to al dente consistency. Simply boil the water, add some salt the entire box of noodles.

Of course you can make this recipe using any type of pasta that you would like. However, it would no longer be called Spaghetti. But all joking aside, you could use Fettuccine, Penne, or Rotini pasta instead and it will still turn out delicious.

Once the noodles are cooked to al dente, remove them and drain in a colander.

Once your pasta is cooked to al dente, drain it in a colander and set aside. Then, using the same pan, saute the onions, and then the garlic.

Rotel Tomatoes & Chiles or Acceptable Substitutes

Next, add in Rotel Tomatoes & Green Chiles and the cream cheese. If you don’t have access to a store-bought can of Rotel, you could substitute a can of diced tomatoes and mix it together with a 4 ounce can of diced green chiles.

Or, let’s not make this complicated. Use whatever diced tomato product that is sitting on the shelf in your pantry. Whether it is a can of fire roasted tomatoes or Italian flavored diced tomatoes it can all be used as a substitute in this chicken casserole recipe.

We have even made this recipe without the tomatoes before when we knew that we had a guest that couldn’t tolerate them.

rotel and cream cheese
To the sautéed onions and garlic, mix in the Rotel Tomatoes & Green Chiles along with the cream cheese.

Whatever you choose to use, mix it with the cream cheese until it has melted completely. Then toss in the chicken broth, half and half, shredded chicken and the spices to the pot. Stir to combine and bring to a simmer.

Next, add the cooked spaghetti noodles and 1 cup of the shredded cheese to the mixture. Stir to combine and allow the cheese to melt.

Cooking Instructions

Pour the chicken spaghetti casserole in a 9 x 13 baking dish that has been sprayed with non-stick cooking spray. Top with the remaining cheese and bake in a preheated oven at 350°F for 20-25 minutes.

Once the noodles and cheese have been mixed with the cream cheese mixture, add it to a greased baking dish.

Remove the casserole from the oven when the top cheese has melted the the mixture is bubbly around the sides.

Let it sit for 5 minutes before serving. Trust me, you don’t want to burn your mouth!

Store leftovers in a covered container in the refrigerator for up to 5 days. Enjoy!
