Slow Cooker Fiesta Chicken and Rice Casserole is a creamy and hearty dinner!

Hi again! I’m back this week with this Slow Cooker Fiesta Chicken and Rice Casserole. This casserole is packed full of flavor! I love casseroles with rice in them, they seem to have a comforting taste to them, probably the carbs, haha.

My mom made a rice casserole growing up that had chicken, cream of chicken soup, broccoli and cheese. Though this casserole has totally different flavors, it sure reminds me of the broccoli dish my mom would make, the same stick to your ribs, creamy type of casserole.

I don’t add the rice until the end, it’s this Farmhouse Spanish rice pictured below. I never add rice straight to the slow cooker, I either cook it separate then add it, or I use Minute rice. This time I cooked up boxed Spanish rice on the stovetop.

fiesta corn, cream of chicken, box of spanish rice, cheese, diced tomatoes and onion.

Below is the photo of the ingredients that get cooked for 6 hours: chicken, seasonings, soup, onion, Mexicorn, and jalapeño. If you don’t know what Mexicorn is, you can see what it looks like. Mexicorn is corn with red and green bell peppers added.

I cook the rice as directed on the package then stir it into the chicken and sauce in the slow cooker at the end of the cooking time. I also add cheese and sour cream.

I let that cook for 20 minutes more for the flavors to combine and to let the cheese melt.

      Can’t wait to try this! I can only find the Knorr rice sides here but they don’t add the tomatoes to make theirs. Can I just add them at the end with the rice instead?

      Can you leave out the rice? Has anyone done this? Trying to make it more diabetic friendly.

      I made this recipe tonight and it was great. The whole family emptied their plates,so it is a keeper! I cannot buy boxed Spanish rice or Mexicorn where I live. For the Mexicorn, I substituted a can of corn and a fresh green and red bell pepper. I looked up a recipe for Spanish rice and with just a few ingredients, it was easy to make.

      Made this tonight was excellent but I added taco seasoning packet to spices on chicken and used southwestern corn because I couldn’t find mexicorn (same as Mexicorn but has black beans) and it was great!!

      Wonderful! Not a big corn fan, so I substituted kidney beans, otherwise followed the recipe exactly. Fantastic! Will definitely make this again! Thank you for such a tasty and easy dinner choice! ☺

      I am printing this recipe now, but it might take awhile to cook it. With the coronavirus of all things that are hard to come by is the Spanish Rice. But I will look again today at the store. The recipe looks so good.

      This is our new family favorite! Everyone in my house at it without complaining! I did not have time to cook on low for 6 hours so I cooked it on high for 4 hours and it turned out great!
