This is the Taco Casserole that I grew up on. Mom’s Taco Casserole features crushed taco-flavored Doritos layered with savory taco flavor-infused ground beef melted Mexican cheese, and green chilies. Make your next taco night extra special with my Mom’s Doritos Taco Casserole recipe.

This Taco Casserole is one that I remember growing up that my Mom would make from time to time.  Of course, as a kid, you put the word “taco” in dinner, then make it with Doritos — you have a winner.  In the early days of my marriage, I made this recipe a lot, but for some reason, I had kind of forgotten about it until one day I saw a bag of Taco Doritos in the store and it came back into my mind!  I love that even when the other bags of Doritos seem to change, the Taco Flavored ones always keep that same look I remember as a kid.

I have never done much research as to which flavor of the Dorito came out first, but from my recollection, I think it was Taco.  This is the flavor I remember eating when I was younger, then the Nacho Cheese ones came out, and those became our favorite.  I even use them in another casserole my family loves called Chicken and Doritos Casserole! These days, there are all sorts of flavors, but these Taco ones are what this recipe calls for.

Speaking of Doritos … This Taco Salad right here is one of our favorite recipes!
