How To Make Keto-Friendly Taco Casserole

Making this gluten-free taco casserole is pretty straightforward. You’ll cook the frozen cauliflower rice according to the package instructions.

If frozen cauliflower rice is not an option for you, you can make our recipe for cilantro lime keto cauliflower rice

Then, in a large bowl, combine the cooked cauliflower rice with the lime juice and the chopped cilantro. Spread the cilantro lime cauliflower rice evenly onto a greased 9×13 greased baking dish.

Next, over medium-high heat in a large skillet, brown the ground beef. Break up the meat and sprinkle with the baking soda and seasonings.

Note that if you opt to tenderize the ground beef with baking soda it will need to sit for about 15 minutes before cooking the meat.

Cook the meat until brown, being sure to break it into pieces with a spatula until cooked. Set the ground beef aside in a large bowl and cook the chopped onion and bell peppers in the same skillet you browned the meat.

Set your oven to 350 degrees and continue to assemble your taco casserole by adding the seasoned taco meat on top of the cauliflower rice being sure to distribute the taco meat evenly.

Then it’s time to prepare the cheesy salsa sauce. In a small pot mix together until fully combined the tomato sauce, diced can of tomatoes with green chilies, heavy cream or sour cream thinned with heavy cream, and spices.

Cook on medium heat and gradually add 1 1/2 cups of shredded cheese. Stir the sauce until the cheese melts and is fully incorporated. 

Now pour the cheesy salsa sauce evenly over the taco meat and cauliflower rice in the baking dish.

Next, sprinkle 2 cups of the shredded cheese over the surface of the keto taco casserole. If adding the raw jalapeños, evenly distribute them over the casserole. Then sprinkle the green onions.

Then just sprinkle the remaining half cup of shredded cheese on top of the casserole. 

Pop your keto casserole in a 350-degree preheated oven and bake for 35-40 minutes until the casserole is hot and bubbly and the top is golden brown.

How To Tenderize Ground Beef With Baking Soda?

When cooking ground beef, for this Mexican ground beef casserole, I sprinkle a little baking soda over the raw beef before cooking and let it sit for 15 minutes.

This helps tenderize the ground beef, making it cook more evenly and quicker.

The general rule is to add 1/4 teaspoon per pound of beef and it’s why I added 1/2 teaspoon to the recipe.

This is totally optional, just note that it will take a little longer to cook the ground beef if you omit it.

Recipe Variations

My family declared that this had to be the best keto taco casserole out there.

I know they are a little biased, but this momma lives for those encouraging compliments.

But if you need some more recipe variations for Taco Tuesday, you can try swapping the ground beef, for ground turkey for those of you who are avoiding beef.

You can even use ground chicken instead, so you’ve got options.

Customize your cheese according to your personal preference. I chose to use a Mexican blend, but you could easily swap it for Monterey Jack, Colby, or cheddar cheese.

Instead of using a can of diced tomatoes and green chiles and tomato sauce, you can use your favorite prepared low carb friendly salsa or even some of our homemade keto Guatemalan salsa.

Even using a prepared salsa verde works well with these flavors.

Feel free to use sugar-free taco seasoning for this low-carb taco casserole instead of the listed spices or your own taco seasoning.

Then, add more of your favorite fresh toppings like sliced black olives, shredded lettuce, diced tomatoes, green peppers, and avocado slices right before serving.

What To Serve With A Low Carb Taco Casserole

This keto ground beef taco bake can certainly be enjoyed without any sides since it is a complete meal on its own.
