INGREDIENTS FOR TACO CASSEROLE:

  • Ground beef: I prefer using lean beef and typically purchase 97/3.
  • White onion: yellow will work fine, too.
  • Gluten free taco seasoning: try making homemade taco seasoning or purchase pre-mixed.
  • Water: to help seasonings mix into ground beef.
  • Lime juice: fresh is best!
  • Black olives & black beans: tasty mix ins. Try different ones if you like.
  • Shredded cheddar: mix half into your casserole and sprinkle the rest on top!
  • Low-carb taco shells: this is my favorite brand! Get them on Amazon or at most local grocery stores (I normally find them by the regular taco shells).

    This actually was a very nice tasting casserole!!! Easy to put together. I did make my own salt-free taco seasoning. I followed the recipe to a "t". I will make this again. Thank you!

    This sounds really good, and I'm considering making this recipe; However, I think the list of ingredients needs to change the wording to say "flour tortillas" instead of "taco shells". I kept in visioning crispy corn taco shells, and was wondering if they should be broken in half throughout the layering process. It wasn't until I saw the pictures, that I realized the recipe should have simply said flour tortillas, or low carb flour tortillas. Hope this helps any other poor soul, who felt lost for a moment like I did.
