Why is this Creamy Chicken Casserole with Rice one of the best things on the internet?

This Creamy Chicken Rice Casserole has it ALL: it’s really easy, utilizes better-for-you ingredients (no need for store-bought cream of mushroom soup), and is a complete, satisfying meal. It’s what casserole dreams are made of and I can’t wait for you to try it!

Easy Chicken and Rice Casserole Ingredients

Here’s what you’ll need to make this delicious, family-friendly, hearty supper:

the ingredients for a creamy chicken and rice casserole in different sized bowls and plates sitting on a marble surface
  • Brown Rice – to start, you’ll need 1 cup of uncooked brown rice. Note: if you have already-cooked brown rice, that’ll make the process *so* much less time consuming, and in that case, you’ll need about 2 1/2 cups of cooked brown rice.
  • Butter – to get started on the other components of the casserole, you’ll need 4 tablespoons of salted butter.
  • Chicken Breasts – 1-1½  pounds of chicken breast (about 2 large chicken breasts) will act as our main source of protein here. Note: again, already-cooked chicken will take some active time off of this recipe. ANY cooked chicken you have will work great (shredded, cubed, sliced, etc.) — you’ll just need about 2 breasts-worth.
  • Salt – because of all of the flavors present in the rest of the dish, the chicken really just needs to be seasoned with salt. We’ll add salt to the gravy too, so in total, you’ll need 1 ½ teaspoons.
  • Mushrooms – 8 ounces of sliced mushrooms go into the gravy. 
  • Garlic – 2 cloves of minced garlic go a long way in flavoring the dish.
  • Onion – along with the garlic, a ½ of a yellow onion gets minced and thrown in for a huge flavor booster.
  • Flour – 4 tablespoons of flour thickens the broth to really help it become a nice, thick, gravy.
  • Chicken Broth – 4 cups of chicken broth (a whole 32-fluid ounce container of broth) provides the liquid base for the gravy.
  • Heavy Cream  – a ½ cup of heavy cream helps to make the gravy nice and creamy.
  • Black Pepper – a 1/4 teaspoon of black pepper goes into the creamy gravy.
  • Shredded Cheese – a cheese topping is a casserole MUST, am I right? To top this chicken and rice casserole, you’ll need about 6 ounces of a mild cheddar cheese.
  • Crackers – this part is optional, but recommended. Cassy topped her casserole with 1 cup of crushed crackers (ANY cracker will do) to add a really nice, crunchy texture to the finished dish.

How to Make Creamy Chicken Casserole with Rice

The process is really easy and straightforward. It’s made EVEN easier, though, if you’re using brown rice that’s already been cooked (check out our article all about batch cooking brown rice HERE). Here’s the full process:

  1. Preheat the oven to 350°F.
  2. Cook the rice – before you do anything else, go ahead and get your brown rice cooking according to package directions. This will take upwards of 35 minutes, so you’ll want to get it going right away. 
  3. Pan sear + slice the chicken – while the rice is cooking, go ahead and cook your chicken breasts! To do this, simply add 1 tablespoon of butter to a large skillet (the same skillet you plan on making the gravy in) over medium-high heat. While the skillet heats, salt the chicken breasts with a ½ teaspoon of salt. Once the skillet is hot, add the chicken and pan sear it for 4 minutes on each side, then cover the skillet, turn the heat down to low, and let the chicken continue to cook for 10 minutes. Once cooked, transfer the chicken to a cutting board and let it rest for 10 minutes. Then, slice it into ½-inch pieces.
  4. Start the gravy – in the same pan that your chicken was cooked in (don’t worry about cleaning it out!), add the other 3 tablespoons of butter. Once melted, add the mushrooms, garlic, and onion and cook for 5-7 minutes, until the onions are translucent and the mushrooms are slightly browned.
  5. Add the flour to the gravy – whisk the flour with a ½ cup of the broth, then pour it into the skillet, along with the rest of the broth, and stir to combine. Let cook for 2-3 minutes, until the mixture boils and thickens, then stir in the heavy cream, salt, and pepper.
  6. Assemble + bake the casserole – add the brown rice to the bottom of a 9×13 casserole dish, then layer the sliced chicken on top of that. Pour the gravy over the chicken, sprinkle the cheese on top, then top with the crushed crackers. Bake at 350°F for 25 minutes, until the cheese is browned and bubbling. 
  7. Serve and enjoy!

Can you put raw chicken in a casserole?

While a lot of casseroles actually call for raw chicken, this isn’t one of them. Pan searing the chicken for this casserole builds a lot of flavor, but if you already have cooked (leftover) chicken on hand, you can totally throw that in instead!

Another time-saving option could be breaking up a rotisserie chicken and sprinkling that into this dish for the chicken layer.

Does covering a baked chicken and rice casserole make it cook faster?

Some chicken and rice casseroles (like THIS one) call for raw rice and utilize the steam from the cooking process to cook the rice, and for casseroles like that, you’d definitely need to tightly cover the casserole. This creamy chicken and rice casserole, on the other hand, calls for already cooked rice, so there isn’t a reason to keep it covered while it’s in the oven. Covering it would actually just keep the top crumble (the crushed crackers) from crisping.

Will this casserole thicken in the oven?

Baking your casserole will help to thicken it slightly. It will thicken as it cools, too. Because of the gravy-style of the casserole, it still won’t be a really thick, sliceable casserole. Instead, it’ll be more of a spoonable texture that mostly holds its form.

How long does it take to make the creamy rice and chicken casserole?

The brown rice itself takes about 45 minutes to cook (which is why I highly recommend batch cooking your brown rice ahead of time, if possible), but while it’s cooking you’ll be multitasking and preparing the chicken and gravy. All in all, this casserole takes about 45 minutes of active time and 25 minutes of inactive time (so about 1 hour and 10 minutes) to bring together.

How do you know when this creamy chicken casserole is done?

Because everything in the casserole is already cooked, you don’t have to worry about double checking for that. Instead, you’ll know that your casserole is done and ready to come out of the oven when the cheese is bubbly and slightly browned.

Is this a healthy chicken and rice casserole?

Ultimately, that’s for you to decide! Take a look at the ingredients — do you tolerate everything on the list well? If so, it can be a nourishing choice for you.

What goes with creamy chicken and rice casserole?

Because this casserole has starch, protein, and healthy fats built into it, it really is a complete meal and can be served as-is. If you’re looking for something to complement it with, though, a simple green salad would be an excellent choice.

How do you store chicken rice casserole?

You’ve got a few options here! If you still have a lot of casserole left, feel free to cover your dish with a tight fitting lid or aluminum foil (lined with parchment paper, if you wish) and store it in the refrigerator that way. If you just have a serving or two left, though, I’d recommend transferring it to a smaller airtight storage container (if you’re in need of a nice set of containers, THIS one is our top choice), and again, storing it in the fridge.

How long will this best chicken and rice casserole last?

Your cooked and stored chicken casserole will stay good for 4-5 days in the fridge.

Can I prep this for the freezer in advance?

You definitely can! The best way to do this is to make the casserole all the way up to the baking step. So, you’ll cook the rice, chicken, and gravy, then assemble your casserole (either in a regular casserole dish or in an aluminum one), leaving off the crackers until just before baking, and store it that way. Then, when you’re ready to enjoy, simply let your casserole thaw in the refrigerator overnight, top it with crackers, and pop it into the oven! 

Time saving hack: to make this process EVEN more efficient, go ahead and crush the crackers during your casserole prep, and store them in the freezer in a Ziplock bag right next to your frozen casserole. 

If I'm making this as a freezer meal, is it best to cook it before I freeze it?

You’ll want each of the ingredients (the rice, chicken, and gravy) cooked before freezing it, but you’ll wait to pop the whole thing in the oven to cook together until you’re ready to enjoy! So you'll follow the full recipe below, but hold off on Step 7 until you've pulled it OUT of the freezer and are ready to make it for dinner that day.

    Taste wise, this recipe is 5 star true winner. I made it for a big family dinner, and even our pickiest eaters loved it. I did hit one hiccup were I had to adapt my recipe, but it was likely user error. Starting off, I’m so used to F&F recipes naturally being GF or having a GF substitute that I didn’t even think about subbing GF flour in the gravy. However, after adding the rest of the stock and milk, it was more thin soup than sauce. I saved it by adding in more GF flour, and ended up with about twice as much gravy as I needed. So if you are planning this sub, start by adding in 1 cup of stock plus heavy cream. Wisk, then add additional stock until you get to a good gravy consistency.

    My other comments are really just preference. I didn’t feel like there was enough rice in the dish and will probably double it next time. I used green beans as my veggie on the side, but we all ended up mixing them in. Next time, I’ll do 2 cans of French green beans on top of the chicken and then add the sauce and cheese on top.

    All in all, another great recipe that will definitely be in a regular rotation at my house!

      Glad you enjoyed it, Shelby-Rae! Thank you for including your notes and suggestions!

  2. Misty McCaslin says:

    My family doesn’t like mushrooms. What is another vegetable you would use instead of that?

    1. Brandi Schilhab says:

      You can skip them altogether, Misty!

  3. Ona says:

    Really enjoyed this recipe! Like the poster below, I would have liked more rice (easy fix next time) and we also had roasted green beans on the side! I too felt the gravy was more soups, but it did thicken up in the oven and thicker as it sat cooling.

    The only thing I added was some fresh thyme from my garden to the gravy, at the end.

    Homerun Cassy!
