Fiesta Chicken Casserole is a Cheesy, Easy, and DELICIOUS Chicken Recipe!

I am a big believer in the casserole. Maybe because I grew up eating them, maybe because they are so efficient (everything in one place), maybe because you can pretty much top any casserole with cheese…whatever the reason is, I am onboard with a casserole recipe. AND if you can somehow get Tex-Mex flavors in there as well, it’s basically the perfect meal!

I have shared a bunch of casserole recipes here on my site, like Cornbread Chicken Casserole, Chicken Divan, and even Frito Pie Casserole. PLUS I have a deep rooted love for Fiesta Chicken. I’ve shared my Slow Cooker Fiesta Chicken recipe as well as a Creamy Fiesta Chicken recipe, and they are both reader favorites. So when I had the idea to make a Fiesta Chicken CASSEROLE, I knew it was going to be good!

How To Make Fiesta Chicken Casserole

The best thing about this casserole is it is essentially a “dump and bake” recipe. It’s an unfortunate turn of phrase, for sure, but it is pretty accurate. If you have leftover or rotisserie chicken, this will be in the oven in 5 minutes.

The Easy Ingredients:

  • Chicken: And type of cooked chicken will work!
  • Ro-Tel: This is a can of diced tomatoes with green chiles. It’s a great ingredient to use in Tex-Mex food! BUT if you don’t have Ro-Tel, you can easily use a can of diced tomatoes and a can of green chiles!
  • Rice: You will have to use Instant Rice in this recipe because you’re adding it in UNcooked, which is great because it absorbs all the flavors from the other ingredients. But to ensure that the rice gets cooked it needs to be instant. If you don’t have Instant Rice, you can cook regular rice until it is al dente, and then add it in to bake. This way it will finish baking with the other ingredients. But for ease, I really recommend Instant!
  • Grated Cheese: I love using Colby Jack, but you can certainly use Cheddar, Monterey Jack, or a blend!
  • Cream of Chicken Soup: Sorry, it’s just necessary in this!
  • Taco Seasoning: This is an easy “catch-all” seasoning.
  • Milk: You have to add a few tablespoons of milk so there is enough liquid for the rice to absorb!
  • Corn: I like using canned corn, but you can use frozen as well!

What Kind of Chicken Do You Use?

Like I said, any type of diced or shredded chicken will work in this recipe. It’s a great way to use up leftover chicken, or absolutely a rotisserie chicken will be great!

If you don’t have cooked chicken already, it’s fine! Just bake about 1- pound of boneless chicken for 25 minutes in a 400°F oven. Dice it and you’re all set!

What Else Can You Add To Fiesta Chicken Casserole?

There are so many things you can add into this recipe. I even included black beans in the recipe card below, because I make this with them quite often! Here are a few more ideas:

  • Sautéed Onion
  • Smoked Paprika
  • Ground Beef or Pork (sub out the chicken!)
  • Jalapenos
  • Chives or Green Onions
  • Garnishes like avocado, sour cream, or shredded lettuce

This was a winner! My hubby loved it and now its a staple in our home.

Yum! We had this wrapped in flour tortillas like burritos with sour cream. So good! Would be awesome to feed a crowd (but make lots), perhaps on game night.

If I wanted to make this in a 9×13 pan, what would the ratio of the ingredients be? (For instance, the 4 cups chicken, would I increase it to 8 cups chicken?)

Can you double the recipe and bake it in a 13×9 dish?

I don’t have instant rice, can I use regular and just add a bit more fluid such as chicken broth? or more milk?

Can you use brown instant rice?

I made this dish about a month ago and my husband and I loved it! He doesn’t like chunks of tomatoes so I puréed the Rotel and it worked just fine. I’m making it again, but this time my can of Rotel is 14.5 ounces. It’s a 45% bonus can. Can I put the whole amount in or should I try to guess 10 ounces?

So delicious. The only thing different I did was add additional cheese cheddar cheese to the top layer. I also added an additional two tablespoons of milk to make sure that the rice was definitely cooked. It was an easy recipe and I would recommend it with a side of fried corn tortilla and a dollop of sour cream.

Question regular taco seasoning or can I use the taco seasoning mix ?

Do you think if the Rotel was left out, there would still be enough liquid to cook the rice? I’ve got a picky eater and if the Rotel goes in, it won’t be eaten.

I made this on a Saturday afternoon and I had all the ingredients on hand so I thought “Why not try it”. It was very easy. On Sunday after it was in the refrigerator for almost 24 hours. I heated some up in the micro wave and ate that with Big Dipper corn chips. I enjoyed it both times and still have some left. It will definitely get made again most likely for a pot luck item. I followed the recipe as written except added some chipotle peppers diced real small in the dumping part. I thought the end result… Read more »

Awesome dish! It was a huge hit with my family. My son loves it rolled in a flour tortilla, like a burrito. Topped with salsa, sour cream and Sriracha.
