• 1 cup short pasta
• 1 chicken breast, cut into cubes
• ½ tsp. garlic powder

By the way, if you have some leftover chicken, you can use it to make some of my chicken casserole recipes - like this chicken taco casserole, this french onion chicken casserole, or this chicken cordon bleu casserole.

Ingredient Substitutions And Suggestions

While I recommend making this chicken and mushroom casserole with the ingredients listed above, there are some ways you can put your own spin on it. So with that said, here are some of my favorite ideas to try.

Swap The Noodles

This recipe calls for short noodles, but really any kind of noodles can be used in this recipe. In fact, I've made this chicken mushroom casserole with both egg noodles and spaghetti noodles, and the results were still super tasty.

Use Different Cuts Of Chicken

You can substitute the chicken breasts for any cut of chicken - like boneless skinless chicken thighs or even chicken tenderloins. 

Change-Up The Mushrooms

For the mushrooms, feel free to use any kind that you want! I typically use shiitake mushrooms or white button mushrooms, but baby bella mushrooms will work great too.

How To Make Chicken Mushroom Casserole

Alright, now it's time for the fun part - making this chicken mushroom casserole!

And, again, making this casserole recipe is about as easy as it gets. I mean, this recipe is literally just a few basic steps, and everything is made together in one dish.

So, let's stop wasting time and get cooking!

Step 1: Prep Work

First things first, you'll want to preheat your oven to 350°F (180°C) and grease a 9x13-inch baking dish with a little butter or olive oil.

Then, in a big bowl, you'll want to add the cream of mushroom soup, chicken broth, sliced mushrooms, pasta, chicken breast, garlic powder, dried thyme, salt, and pepper. Now, after you've added those ingredients to a bowl, you'll want to give 'em a good mix until they fully combine.

Step 2: Bake The Casserole

Once your creamy chicken mixture is fully combined, you'll want to transfer the mix to your prepared baking dish and cover it with tin foil.

Then, after you've got that looking good, you can put the casserole in the oven and bake it for 30 minutes. After 30 minutes is up, remove the tin foil, and bake it for another 15 minutes, or until the chicken and pasta are fully cooked.

Step 3: Finish With Extra Cheese

Ok, so once the pasta and chicken are both fully cooked, you can remove the casserole dish from the oven and add/mix the sour cream into it. By the way, it doesn't have to be perfect, but you'll definitely want to make sure the sour cream is evenly spread throughout the casserole.

Anyway, when you've got that looking good, you can top your casserole with the shredded cheese and broil it for about 3 minutes - just until the cheese melts and it’s nice and bubbly.

Finally, after it's done cooking, you can garnish this creamy chicken and mushroom casserole with some parsley, serve it, and enjoy!

How To Store Chicken Mushroom Casserole

This recipe for chicken mushroom casserole makes about 6-8 servings, so it's perfect for a big family dinner. If you're lucky, you might even end up with leftovers!

Speaking of leftovers, to store them, you'll want to allow the casserole to cool completely first, and then you can transfer it to an airtight container. Stored this way, it should keep in the fridge for 3-4 days.

That said, if you want to keep this casserole for longer, you can store it in an airtight container - or freezer-safe bag - and store it in the freezer for about 6 months.

How To Reheat Chicken Mushroom Casserole

When you're ready to enjoy your mushroom chicken casserole again, you'll definitely want to reheat it first.

So, to reheat it, you can just put the casserole back in a baking dish and warm it in the oven at 350°F for around 10 minutes - or until it's warmed throughout.

Alternatively, if you want to reheat just a single serving of it, you can use the microwave. Just heat it up in 30-second increments until it reaches your desired temperature.

Wrapping It Up

Well, that's how to make a chicken mushroom casserole in just a few simple steps!

Out of every chicken casserole recipe I've come up with, I honestly think this might be one of the best ones yet. It's so rich and decadent, yet it couldn't be more quick and simple to make.
