***** 6/24/2019 NEW TACO RECIPE *****

I've had a keto taco casserole recipe on here for a while.  And it was good, but I wanted something GREAT!  I also wanted a taco casserole that was made in a cast iron skillet.

So off I went to create it.  After a few tries, I created this beautiful keto taco casserole while still keeping the general spirit of the original.

Kitchen Essentials For This Taco Recipe

A cast iron skillet is a must.  I mean, I suppose it is not an absolute must, but you'll have to alter the instructions!  You can do most of the preparations in a pan and then transfer it to an oven-safe 8x8 baking dish before pouring the egg mixture and cheese on top.

You'll also need a mixing bowl for preparing the egg and cheese mixture.

Everything else should be easy peasy!


Taco Pie Flavors

There are so many lovely flavors in this keto taco casserole.

Let's see, we have taco seasoning which you can get playful with.  Use a packaged one so long as it is low carb or make your own!  You can really play with the flavor of the overall dish with this one.

Then we have the Rotel.  If you don't know what Rotel is like Petite Diced Tomatoes with a kick.  You should be able to find it in your local grocery store next to the Petite Diced Tomatoes.

And, of course, sour cream.  This provides some thickness and tanginess.

Lastly cheese and egg - we all know what those taste like!  The egg gives it a nice little fluff!

How to Make a Taco Casserole

The great thing about this recipe is that most of it is done within the cast iron skillet.  SCORE!

You start with browning the beef and cooking the onions. Then add in the taco seasoning and mix it up good.

Then you get to slap on some sour cream and Rotel!  Stir it up and get it nice and thick and creamy.

Once it is all mixed up, you simply press it down flat to cover the bottom of the skillet.

Next, you get to add the egg, sour cream and cheese mixture.  Just pour it over the top evenly, making sure most of the beef is covered.

How to Store a Taco Casserole

I generally don't store things in the skillet.  The reason I do not is that I don't like it to stay wet for too long.

Scoop any leftovers out and store in and airtight container in the fridge.  It will stay fresh for a couple of days for sure.

Easy Taco Casserole Toppings
