Ready to eat in 10 minutes and filled with delicious flavorings like taco seasoning, green chiles, sour cream, tender chicken, and tortillas, this Mexican-inspired microwave chicken tortilla casserole recipe is a must-make for friends and family.

Today I’m sharing one of my favorite summer supper recipes. This easy chicken tortilla casserole recipe blissfully avoids heating up your house as it uses a microwave. This always surprises people when they taste it. I think folks expect a microwave casserole to be tough and chewy, but you’ll find this one is cooked just right.

I came upon this recipe in one of those little check-out cookbooks right after Ricky and I got married. Every recipe in that cookbook was good and wouldn’t you know, I lost it within the year ~laughs at her own disorganization~. Fortunately, I had this one memorized because I had made it so much! My husband and I love it and it also reheats well.

This Mexican casserole is packed with flavor, thanks to the taco seasoning, cilantro, green chiles, and french fried onions. It’s also ready to go from start to finish in under 10 minutes. So when it comes to easy casserole recipes, I don’t think you’ll find an easier one anywhere.

Now let’s get cooking so we can get back to enjoying all of those sacred summer moments with our family!

How to Make Chicken Tortilla Casserole in the Microwave

Chop fresh cilantro.

Now let’s get started. This is SUPER easy and it’s gonna go fast so stay with me here :).

First, chop your fresh cilantro.

Add all ingredients to mixing bowl.

Then dump all of your ingredients into a large bowl.

Note: We’re saving half of the cheese and half of the onions for the topping.

Stir ingredients together.

Stir that all up until well combined – or close enough :).

It’s not like the world is gonna end if we don’t stir it just right.

Add one torn tortilla to bowl.

Now take one of your tortillas, tear it into small pieces, and add that to the bowl also.

Stir together once more.

Stir it up again.

Place other tortilla in microwave-safe bowl.

Place the other tortilla on the bottom of a microwave-safe pie plate.

Spoon mixture into tortilla.

Spoon your chicken mixture into it.

Microwave chicken tortilla casserole for 5 minutes.

Microwave for five minutes.

Top with remaining french fried onions.

Remove from microwave and top with remaining french fried onions…

Top casserole with remaining cheese.

and shredded cheese.

Return to the microwave for another minute or until cheese is melted.

As mentioned, these casserole leftovers reheat really well. Store them in an airtight container in the fridge for up to 4 days. Once again, reheat in the microwave.

Recipe Notes

  • I like to pick up a rotisserie chicken for a quick lunch on those crazy days. Usually, I can get one for the same price as an uncooked fryer so it’s like someone did the work for me. I just have some for lunch and save the rest for this casserole! Another great way to get chicken on the cheap is to buy leg quarters in ten-pound bags. I boil all of the leg quarters in a large stockpot, shred and bag the chicken, and then use the stock for chicken noodle soup or chicken stew.
  • In saying that, you can use any kind of cooked chicken in this casserole recipe, including shredded chicken breast. Just as long as it’s about 2 cups, you’ll be good to go.
  • While my chicken tortilla casserole tastes delicious on its own as a main dish, you can definitely add your favorite taco toppings on top. Like a dollop of sour cream, chopped green onion, chopped bell pepper, diced avocado or guacamole, salsa or salsa verde, pico de gallo or diced tomatoes, hot sauce, and lime juice.
  • Feel free to substitute the cheddar cheese for your favorite. Monterey Jack cheese or a Mexican cheese blend would be perfect!
  • While you can swap the tortillas for corn tortillas, you’ll need more to cover the base. They’re also crumblier, so be careful when serving.

    This sounds so yummy! I no longer use a microwave, but my toaster oven is just raining to go. I can see myself making this recipe a lot because it is so easy and looks so delicious. I’m also thinking that this would be a great way to use any leftover chili; just omit the taco seasoning and chicken and swap in the chili. (I can also see myself making this with cooked shrimp too.)

  2. What about using chips from the restaurant. I live 45 minutes town and just realized I have one tortilla shell. This recipe looks awesome. I’m already fan

  3. I have made this dish several times. My sons are always willing to try anything Ms. Christy posts! I have always used leftover chicken or the rotisserie chicken, however this week I didn’t have chicken, but I did have ground beef and all the other ingredients on hand. I just cooked the ground beef and added the taco seasoning according to the instructions, and then put that in as a substitute for the chicken. It was an even bigger hit than the chicken! Served with a refreshing fire and ice salad, it’s a great supper with no oven heating up the house!

  4. If you are at your local big box store near closing time, those rotisserie chickens go on half price.

  5. Just tried this tonight and it was delicious. I didn’t have chicken but used ground beef. I added black beans and topped one with black olives too. Yummy!!

  6. I am not a fan of cilantro. It tastes like soap. Don’t ask me how I know what soap tastes like, suffice to say that as a youth I learned it is wise not to say certain words. Is there a substitute for cilantro in this recipe? Perhaps parsley?

  7. Thanks so much for sharing another fantastic recipe. I was wondering when put in the Micro does the tortilla cook so it’s not doughy? Other wise I could pre-cook the tortillas on top of the stove just to stiffen them a bit then add the rest and nuke. Have your wonderful cook book and read your recipes like my Bible. Thanks so much.
