King Ranch Chicken Casserole

I recently discovered king ranch chicken casserole.  I love to make it for our family, and it's my go-to recipe when I take a meal to someone.

I started with this recipe from allrecipes and made a few adjustments:

butter instead of vegetable oil
omit the peppers
increase Rotel to two cans, drained
omit chicken broth
omit ancho chile powder
increase chipotle powder to 1-1/2 teaspoons (I use this blend)
cook 1 lb. chicken thighs using this recipe for the instant pot
reduce cheddar cheese to 4 oz
substitute tortilla chips for the corn tortillas

I use a 9x9 pan.  I save all the cheese for the top.  I bake for 35 minutes at 350 degrees.

This makes a much thicker casserole that is almost like a lasagna.
