It demands so little, and it’s easy, delicious, and full of texture.

Plus, you can make a big batch and heat up the leftovers for dinner on any other night of the week. I love leftovers.

You can think of this recipe as a big nacho bake, of sorts. But with less cheese, more salsa, and a casserole-like texture.

Tex Mex Casserole is one of my favorite tex mex recipes, with chicken, chips, and salsa

It won’t and is not supposed to have the crispness of a tray of nachos, but rather the nachos soak up the salsa and take on a more tortilla-like texture that makes for a hearty bite.

You also gets bits of corn, black beans, scallions, and gooey cheese to tie it all together, and a sprinkling of taco seasoning to enhance the tex mex flavors that go so well in dishes like this.

Let me show you how simple it is to put together this Mexican Chicken Casserole.

  • 4 oz tortilla chips broken into large pieces (2 cups)

  • 15 oz can black beans drained and rinsed (can do pinto beans too)
  • 3 cups cooked chicken breast diced

  • 2 tbsp taco seasoning
  • sour cream for garnish (optional)

  • Preheat the oven to 400 degrees F.
  • In a large bowl, combine the tortilla chips, corn, black beans, diced chicken, cheese, salsa, scallions, and taco seasoning. Stir it all together very well, being careful not to crush the tortilla chips too much. Taste the mixture and adjust seasoning if necessary (and keep in mind this will taste wetter than when it comes out of the oven).
