This is the taco casserole I grew up on, the one my Mom always made.  It has a crust made of Taco Flavored Doritos and it’s full of seasoned ground beef and lots of cheese!


Mom's Taco Casserole - An Affair from the Heart

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.  I know I made it early in my marriage, 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 flavor, but these Taco ones are what this recipe calls for.  The next problem came when I was looking for the recipe!


Back in the day, I didn’t have tons of recipes.  These days?  I have recipes and ideas for recipes everywhere!  A long time ago, my Mom bought me a big recipe book with these plastic sleeves to slip all of my recipes in.  Before that they had been toted around in a brown index card box.  For the longest time they were super organized, then … I started blogging.  If you didn’t already know, I didn’t really plan to become a food blogger?  It sort of happened by accident.  But, when it did, I wanted to share all of my favorites with you, so these book has slowly been dismantled.  Now the recipes are here and there and everywhere.  In to do piles, and folders of “Recipes Made -Need to Blog” or “Recipes Blogged” or “Recipes I Want to Make” — you get the idea.


I could picture it though.  It was written on a plain white index card.  I flipped through that book over and over again.  Asked my Mom,  she hadn’t made this in forever.  Her and my Step Dad eat out quite a bit, and she finds cooking for two challenging.   She had one recipe that she came across, but it just didn’t sound right?  I decide to flip through the book once more and Ta-Da! There it was!

It was time to crack open that bag of Taco Flavored Doritos and get to work!  I changed up a couple of the ingredients,  just a little bit.

It only bakes for about 20 minutes.  Let it rest for 5, before cutting into it.  I topped ours with some sliced green onion, and we served it with a lettuce salad.  Perfect weeknight dinner.


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