This Microwave Mexican Casserole is something I often put together when I have leftover rotisserie chicken and especially with leftover turkey from Thanksgiving when we want something a bit different than the traditional Thanksgiving leftovers.
You don’t have to limit yourself to just leftover chicken or turkey for this casserole. Use frozen chicken like grilled, diced, or pulled chicken. Leftover taco meat or ground beef and even fajita meat are also great alternatives. You can really put your own spin on this casserole to make it your own.
I also use up the leftover crushed tortilla chips or ripped up corn tortillas that are too small and fragile to be used anymore. This casserole is a great way to use up a few things still hanging around the kitchen.

What’s in a Mexican Casserole?
This casserole has no rules. I just use foods I traditionally use when I cook TexMex or Mexican along with salsa, and then layer them together.
- corn tortillas
- peppers and onions (frozen bag)
How do you make a Mexican Casserole?
My basic layers are:
Between each of these three layers I add cheese and ripped up corn tortillas and salsa.
I start with a layer of rice, and then I go from there. Usually I buy the $1 packages of Knorr’s rice – either Mexican Rice, Taco Rice, or Spanish Rice. It’s very easy to make in the microwave. You just add 2 cups of water and cook for 10 minutes, and it’s done. Then, I start layering the casserole together.
Next is a can of pinto beans or black beans as well as a can of corn. Sometimes I switch out the beans for Ranch Style Beans, which are also known as Chili Beans.
Don’t forget to add cheese and ripped up tortillas between the layers. I also add one layer of frozen bell peppers and onions and a layer salsa in the middle.
Usually the meat layers are leftover rotssierie chicken, but I’ve used frozen fajita meat, frozen chicken, canned chicken, leftover turkey, leftover taco meat, and even plain ground beef.
The final two layers are salsa and cheese.
How do you cook a Microwave Mexican Casserole?
This part is easy. Since the ingredients are all precooked, you don’t need to worry about getting to a certain temperature. So, I cook the casserole for about 8-10 minutes on High so the cheese is melted, and it’s hot throughout the casserole.
