This Mexican chicken casserole comes together in one pan with hearty flavors and gooey cheese for a dinner that everyone in my house asks for on busy nights. All the comfort of your favorite burritos or enchiladas but with a fraction of the prep and cleanup.
I first put this together after a long day when I needed something filling and simple. Now it is in our weekly rotation and everyone digs in for seconds.

Step-by-Step Instructions

I love loading this casserole up with extra cheese because my family loves that super creamy top layer. My kids pile on crunchy tortilla chips and call it nacho night which always makes me smile.
Storage Tips
Keep leftovers in the fridge for up to three to four days in a tightly sealed container. This casserole also freezes very well. Just portion it into individual servings or freeze the whole dish wrapped tightly in plastic and foil for up to three months. Thaw overnight in the fridge before reheating for best texture.
Ingredient Substitutions
You can swap out the shredded chicken for pulled pork seasoned ground beef or even roasted cauliflower for a vegetarian spin. Switch the beans for pinto if you like or add chopped bell peppers for extra color and crunch. The cheese is flexible too so use cheddar pepper jack or any good melting cheese that you love.
Serving Suggestions
Serve this casserole hot out of the oven with sides like fresh lime wedges a simple green salad or warm tortillas. It is fantastic for potlucks and makes a hearty filling for burritos or quesadillas the next day. We sometimes top individual plates with pickled jalapenos for a spicy finish.
Cultural Context
While not a traditional Mexican dish this casserole uses classic Tex Mex elements like salsa beans and melting cheese all layered for American comfort. It is a great example of blending Mexican ingredients into easy weeknight cooking and it really captures that crowd pleasing family style spirit.
