Chicken Black Beans and Rice Casserole

I feel like I should start this off by saying that casseroles are one of the harder to photograph items for a food blog. In reality, we have to make the food look appetizing and yummy for y’all and casseroles and brown foods are the pits to take appetizing pictures of! All that to say, I’m hoping you guys give this recipe a shot because the pictures do not do it justice. It’s so good!

How to Store, Freeze, and Reheat Chicken, Black Beans and Rice Casserole

To store chicken, black beans, and rice casserole, allow it to cool completely and place it in an airtight container in the refrigerator for up to 3 days.

When freezing this casserole, be sure that it has cooled completely. Add the casserole to a freezer-safe, airtight container and store in the freezer for up to 6 months. Allow the casserole to thaw overnight in the refrigerator before reheating.

To reheat, I recommend adding it to a skillet on the stove over medium heat, stirring frequently until heated through. You can also reheat it, covered in the microwave.

  1. The recipe was great but Prep time 5 mins… I wish. I prepped for 1 hour before putting in the oven. This should be changed!

    1. Hi Lauren,
      I’m glad you enjoyed the recipe. I’d love to help troubleshoot the prep time! The prep should only involve mixing the two items and then layering them in the dish since it calls for pre-cooked chicken and rice. Did your hour prep time involve cooking chicken and rice?

  2. Do you think there would be any problem with mixing the cheese (or, maybe half the cheese) in with the rice mixture?

      1. Hello again Kara . . . I followed the recipe exactly and we found it to be a little “dry” . . . so with the leftovers the next day, I stirred in a cup of condensed cream of chicken soup to the remaining two thirds of the casserole, smashed it all back into the dish, and sprinkled another cup of grated cheese on top before reheating. Y-U-M-M-Y!!

        1. I love this idea! I’m definitely going to try that the next time I make it. Thank you so much for the suggestion 🙂

          1. Hi Ruth Ann, If you’re using canned corn you’ll want to drain it. The rotel does not need to be drained. Hope you enjoy!
