Making Ahead. This Mexican casserole is great for making ahead of time. Just prepare everything in the casserole dish up until cooking. Instead of cooking it in the oven, keep it covered in the fridge until you’re ready to make it.

It will last about 3-4 days in the fridge. Or you could put it in a freezer-safe container and freeze it for 3-4 months until ready to bake. Perfect for meal prepping, taking to friends in need and more.

Leftovers. Store any leftovers in an airtight container in the fridge- which should last for 3-4 days. Leftovers of this casserole make a great lunch for the next day- yummy!! Just heat it up in the microwave when you’re ready to eat it.

    This was amazing!! It had so much flavor & was very simple to make. We love Mexican food, so having it in a casserole form is a great idea! Perfect for feeding a crowd.

    Delicious! I always make your mexican rice when we Have MEXICAN food then freeze the LEFTOVERS specifically to make this casserole!

  4. In your recipe you ask for Mexican rice. Is this a particular kind of rice as in short , long grain, or Jasmine rice?

    Well, by the end of making this I don’t know if I truly “followed” the recipe, but it was delicious whatever it was. Haha. Very flavorful, creamy, satisfying.
    Here are the changes I made: I added cooked yellow and green pepper (chopped) to add some veggies; I used about 4 cups of leftover chicken instead of cooking it with garlic and taco seasoning; I accidentally used all of both cans of the cream of chicken soup, so to compensate I cut the cheese down to 3 cups; I used a combination of pepper jack, cheddar, and colby jack cheeses; and I didn’t bother with the cilantro since there was so little involved.
    Anyway, it was fantastic. The flavors were a bit much for my two year old, so I added some leftover white rice to his to make it a little more bland, and he gobbled it up.

  6. Is the rice measurement before cooking it or after cooking it? I assume you cook it before assembling the casserole? Thanks!

    It was good. I didn’t bother with layering it, I just mixed everything together and topped it with cheese. Delicious! Also, it didn’t need the full 40 minutes, everything already cooked so just did 20 minutes.
