You know those meals that are always a win? Like every time you make it, you think, “Why don’t I make this more often?” Fiesta Chicken Casserole is always, always, always a win for me. It’s easy as heck, I always have the ingredients, and everyone loves it. It’s a total slam dunk!

Chicken, rice, tomatoes, corn, and black beans are enveloped in a creamy and spicy sauce for a perfect blend of comfort and zing. This Fiesta Chicken Casserole is one of my most popular recipes for a reason!

Fiesta Chicken Casserole Ingredients

This meal is one of my favorites because I almost always have all of the ingredients on hand. I like to stock up on Rotel and Taco seasoning because I use them all the time. These two ingredients are so amazing for adding flavor fast.

For Fiesta Chicken Casserole, all you’ll need is:

  • cooked shredded chicken (you could use shredded rotisserie chicken or cook some chicken breasts yourself)
  • uncooked instant rice (Minute rice works great)
  • Rotel Diced Tomatoes and Green Chiles
  • taco seasoning
  • milk
  • corn
  • cream of chicken soup
  • black beans
  • shredded cheddar cheese

How to Make Fiesta Chicken Casserole

I almost feel silly writing out a description of how to make this because it is so easy. Literally all you have to do is mix all the ingredients together (except 1/2 cup of the cheese for topping) and pour it in a greased baking dish. That’s all the prep work, I swear. Then, let it bake for half an hour, covered, and then remove the foil for the last 10 minutes of baking. That’s it!

Once your casserole is baked, you can serve it up and top with shredded lettuce, sour cream, guacamole, salsa, or lime, if you’d like. This recipe is great as is, but if you have these ingredients, these toppings add a nice fresh element to the dish.

Dump Casseroles

Dump Casseroles are kind of my favorite thing ever. I love how simple they are– I hardly have to think at all. I just dump everything in a baking dish set the timer and walk away for a while. Sometimes I like to see how much I can get done in the time that it’s cooking, and sometimes I just sit on the couch scrolling the whole time. Casseroles are great if you want a little extra time to be productive and if you want a little extra time to rest. Here are a few of my favorite easy meals!

  1. I have made this 2 times the first time we ate it as a dinner. Then we bought scoops and now we eat it like a dip. Add black olives, top it with sour cream mixed with salt and pepper. No matter how you eat it this is an amazing dish.

  2. Delicious! I like to use the leftovers of any Mexican Rice Casserole as burrito filling!

  3. Are you using uncooked rice? Does the rice get nice and fluffy? It doesn’t seem like there would be enough liquid. Would love to hear how you make this rice magic happen. Thanks!

  4. This was VERY VERY VERY good! The whole family loved it, and it was so easy! I bought a non seasoned rotisserie chicken from walmart, took off all the meat, and used that for the chicken. This is going in my recipe book and will bring for pot lucks. Thank you for your recipe! We are going to try more of your recipes. I needed easy and delicous, and this was it!

  5. Delicious and so easy! Love that it is dump and bake!

  6. Made this today – I cannot stop eating it!
