Easy Casserole Recipe:

I love a good casserole recipe. It’s the classic comfort food and my kids love them.

This Chicken Spaghetti Casserole is so simple to make! It’s so creamy and full of flavor. I use cooked and shredded chicken for this recipe.

To make life easier I usually make the chicken ahead of time in the slow cooker. I use my recipe for my All-Purpose Slow Cooker Chicken. It’s perfect for recipes like this. 

How to make Chicken Spaghetti Casserole:

This chicken spaghetti casserole recipe features Rotel and Cream Cheese as the main flavor profile.

Start by cooking your spaghetti according to the package directions. You want to cook them al dente as they will cook more in the oven when baking the casserole.

In a large pot sauté your onions and then add the Rotel and cream cheese. Add in all your remaining ingredients except the cheese to the pot.

Mix it all together and bring to a simmer. Add in the noodles and mix well. Add everything to a large casserole dish and top with the shredded cheese. Bake and then serve!

Ingredients:

  • Spaghetti
  • Oil
  • Onion: yellow onions that has been diced.
  • Minced Garlic
  • Rotel: drained well.
  • Cream Cheese: that has been softened to room temperature.
  • Chicken Broth
  • Half and Half
  • Chicken Breast: that has been cooked and shredded. This recipe is perfect for a rotisserie chicken.
  • Seasoning: cumin, salt, & pepper.
  • Cheese: I used shredded cheddar cheese

Chicken Spaghetti Casserole Directions:

Step one: Start by cooking your spaghetti according to the package directions.

Once it is fully cooked then go ahead and drain your spaghetti and set aside.

Step two: In the same large pot (without any spaghetti) warm oil over medium/low heat.

Sauté your diced onions for several minutes then add garlic to saute for 30 seconds.

Next, add in your drained Rotel and cream cheese. Stirring constantly until your cream cheese is melted.

  • Tip: You don’t want the garlic to cook too long since it does tend to burn quickly. Adding the garlic the last 30 seconds will prevent it from burning and help keep the amazing flavor.

Step three: To the same pot add chicken broth, half and half, cooked and shredded chicken, cumin, salt, and pepper.

Mix this all together well and then bring to a simmer while on medium heat.

Step four: Next add in cooked spaghetti and just 1 cup of shredded cheese to your pot.

The rest of your cheese will go onto of your casserole before you bake it.

Mix until well combined and then add to a casserole dish prepared with nonstick cooking spray.

Step five: Preheat oven for your casserole. Top your casserole with remaining shredded cheese and then place in the oven.

You only need to bake long enough for the cheese to melt and casserole is warm throughout.

Freezing Spaghetti Casserole:

Casseroles are a great make-ahead dinner recipe. To freeze this recipe cook it according to the directions in an aluminum casserole dish.

Place foil on top once cooked and cooled and seal well.

Place in the freezer for up to 1 month. When you are ready to reheat remove it from the freezer and place in your fridge overnight to thaw.

How to serve the Spaghetti Casserole:

As you know, spaghetti is best served with tongs or a spaghetti serving spoon.

With this being baked as a casserole, you may need a knife to help you cut the spaghetti if it got too hard during cooking.

Using tongs grab some of the casserole and place it on a plate. A serving spoon may also help.

What to serve with Chicken Spaghetti Casserole:

Since this chicken spaghetti with Rotel and cheese is fully of flavor I love to serve this with some simple sides.

I classic house salad goes great with this casserole. I also enjoy making Roasted Honey Carrots for a little sweet side to go with the zesty spaghetti.

Try some of my other favorite casseroles:

Funeral PotatoesFuneral Potatoes sometimes called Party Potatoes or just Cheesy Potatoes is a great recipe for dinner or a side for the holidays! Made with cheese, sour cream, butter and topped with corn flakes this will be your favorite potato dish ever!

Dorito Chicken CasseroleThis Dorito Chicken Casserole was a huge hit with my family. A creamy chicken base topped with Dorito chips then baked. I knew my kids would love this since they love my recipe for Ritz Cracker Chicken Casserole so much and this is pretty simple.

The Best Breakfast CasseroleThe Best Breakfast Casserole is simple to make and makes the perfect breakfast or dinner. Made with sausage, peppers, onions, and shredded hash brown. It’s easy to prepare and taste great

  1. This is my second go at it. Wonderful. This time i added a can of cream of mushrooms. I have a football player an this is a perfect meal for a hungry family. They loved it. Thank you

  2. Very good, but this recipe makes a ton! (almost overflowing a 9×13 pan). Next time Iโ€™ll reduce pasta by half, and the chicken broth by a bit more than that (to thinken up the final dish).

    1. Just made this tonight and it was EXCELLENT!! As someone posted it makes alot ๐Ÿคทโ€โ™€๏ธ

  3. This recipe is great when you substitute spaghetti squash instead of regular spaghetti. Did not add the squash to the sauce. I baked it in the microwave until done the added sauce on top.

  4. Great recipe. I used a little over 1/2 lb linguine and reduced the chicken broth to 1 cup. I would also recommend using less salt. Additionally, I didn’t toss the liquid from the tomatoes.

    I took pictures, but there is no place to upload them!

    Thanks, Jenni!
