Chicken Casserole: A Family Favorite Dinner

When I made this chicken spaghetti recipe for the first time last week, my husband ate it for about 5 meals in a row and proceeded to ask me to make it again the next week.

My kids eagerly scarfed it down as well. Tonight’s batch ended up on about every area of exposed skin on my 18 month old, but I take that as a sign he liked it. Needless to say, this recipe is a keeper!

While this chicken casserole recipe is baked in a 9×13 dish, I oftentimes split it into two, 8×8 dishes and freeze one for later. More on that soon though!

How to Make Chicken Spaghetti

Here is what you’ll need:

Ingredients for chicken spaghetti

Ingredients ready? Let’s do this.

Cook the pasta according to the package instructions, until al dente (slightly undercooked). Undercooking it keeps it from getting mushy while baking. This is especially important to do if you are going to make this a freezer meal.

While that pasta is cooking is a great time to sautee those chopped veggies. Multitasking is your friend for this recipe.

In a large mixing bowl, gently stir together the cooked pasta, cream of mushroom soup, chicken broth, chicken, veggies and seasoning.

Now please take note of this: Add in only 1 1/2 cups of the cheese. I always get moving too fast and add it ALL in at this point. You need some to sprinkle over the top so restrain yourself!

Here it is all mixed up. Yum. Or yuck. Not sure.

Either split it up between two 8×8 dishes or put it all in one 9×13 dish. Top with remaining cheese. Assuming you listened to my warning above about not mixing in all of the cheese, that is.

How to Freeze Chicken Spaghetti

Freeze for Later: Here’s the fun part: If you have split it into two 8×8 dishes, you’ve just made two dinners! To freeze one of the 8×8 Chicken Spaghetti portions, simply wrap it tightly or place a lid (if you have one) on your baking dish. (Here are the freezing containers we use and recommend for recipes like this.) You can freeze it for 4+ months! Even longer if you’ve packaged it well.

Prepare From Frozen: Place frozen casserole into the fridge and let thaw for 24+ hours. Follow step 5!

This freezer-friendly Chicken Spaghetti Casserole will keep your family coming back for more deliciousness. 


  • 1 pound whole wheat pasta
  • Two (10 and 3/4-ounce) cans organic cream of mushroom soup
  • 1 cup chicken broth
  • 23 chicken breasts, fully cooked and chopped or shredded (roughly 3 cups)
  • 1/2 cup finely diced green bell pepper
  • 1/2 cup finely diced red bell pepper
  • 1 small or medium onion, finely diced
  • 1 teaspoon seasoned salt, such as Lawry’s Seasoned Salt or use this DIY recipe
  • 1/8 to 1/4 teaspoon cayenne pepper
  • Salt and freshly ground black pepper, to taste
  • 2 1/2 cups shredded sharp Cheddar, divided


Make It Now:

  1. Preheat the oven to 350°F. Grease a 9×13 inch casserole dish or two 8×8 dishes with cooking spray.
  2. Cook the pasta according to the package instructions, until al dente (slightly undercooked). When the pasta is done, drain it in a colander over the sink.
  3. While pasta is cooking, saute the bell peppers & onions in a bit of olive oil until they begin to soften (about 4-5 minutes).
  4. In a large mixing bowl, gently stir together the cooked pasta with the cream of mushroom soup, chicken broth, chicken, sauteed veggies, seasoned salt, cayenne, and 1 1/2 cups of the cheese. Sprinkle it all with salt and pepper, to your preference.
  5. Place the mixture in the dish (or dishes) and top with the remaining 1 cup of cheese. (Freezing instructions begin here.)
  6. Bake until bubbly around the edges, about 40-45 minutes. (If the cheese on top starts to get too dark, cover with foil.)

Freeze For Later: Follow steps 1-5 (do not bake). Cover the casserole dishes with a few layers of plastic wrap and foil. Squeeze out any excess air and freeze.

Prepare From Frozen: Thaw. (Here are three safe ways to thaw freezer meals.) Follow step 6. If it’s still slightly frozen in the middle, you’ll just have to cook it longer than the recipe calls for or defrost a bit in the microwave before baking. Cover it with foil if the top gets too brown in the oven.
