Ingredients

Taco Casserole Ingredients - ground beef, rotel, taco seasoning, butter, cauliflower rice, garlic salt, cream cheese, cheese
  • Ground Beef – Substitute ground beef with ground turkey or ground chicken. I have even used a combination of beef and turkey.
  • Rotel – If you want spicier taste, use the hot Rotel.
  • Taco Seasoning – We use Homemade Taco Seasoning Mix
  • Frozen Cauliflower Rice – Feel free to use fresh cauliflower
  • Cheddar Cheese – Substitute the cheese for Mexican Cheese blend, Colby Jack or Monterey Jack Cheese

Scroll to the bottom for the full recipe in the recipe card.

Variations Ideas

  • Vegetables – If you want to sneak in veggies, add in bell pepper and onion.
  • Salsa – Substitute the Rotel for a salsa of your choice or make Homemade Salsa Recipe.
  • Spices – For added flavor and a hint spice add in a teaspoon of red pepper flakes into the beef mixture.
  • Jalapeños – Slice some fresh jalapenos before baking for delicious flavor.

  • Step 8 – Bake for 20 minutes-30 minutes until heated through and the cheese begins to brown. Serve topped with fresh cilantro and enjoy.

Expert Tips

  • Layering Ingredients – Instead of making a cauliflower layer and a meat layer you can mix it all in the skillet before adding it to the casserole dish.  We have cooked it both ways and it tastes great either way.
  • Cauliflower Mixture – If the cauliflower layer is a little too thick, try adding a little heavy cream to the mixture.
  • Make Ahead – This casserole is a great dish to make ahead and store in the fridge until ready to heat. If you have leftover taco meat, use it to make this taco casserole.

Serving Suggestions

The taco casserole can be served as is but we love to serve with a green salad or Air Fryer Broccoli for an easy side dish. We have even served with Best Mexican White Cheese Dip Recipe and keto tortilla chips for another easy side dish.

It would even be delicious wrapped in a keto friendly flour tortilla or a tortilla of your choice.

First of all, I know it can seem overwhelming initially. However, once you understand the Keto lifestyle it is very simple.

There is a great book for beginners here that you might want to pick up. It is a really great resource to help get you started on this Keto journey.

I even spotted the Keto Crock Pot Cookbook.

Frequently Asked Questions

Can I Use Fresh Cauliflower?

You can make your own cauliflower rice if you prefer that to frozen. Either will work perfectly in this recipe. We use frozen cauliflower rice a lot because it is quick but I also like to make my own Cauliflower Rice if I have time. It is very easy to do.
In a matter of minutes your fresh cauliflower is chopped up into a “rice”.
We also use this for Easy Cheesy Cauliflower Rice Recipe.

Yes, you can make this recipe in the crockpot. Yes, prepare the recipe as directed but layer it in the slow cooker and cook on low for about 3-4 hours.

Store the leftovers in an airtight container in the refrigerator. This casserole will stay fresh for up to 3-4 days.

How to Reheat Taco Casserole

Reheat leftovers in the microwave or the oven depending how much you have leftover.

    I’m so glady ou loved it!

    Recipe was absolutely delicious and I will be making it again. I would love to know what the serving size is rather then getting out eight bowls and measuring to try and figure it out. I used stewed tomatoes and some jalapeño slices (put both in my blender) because I had no rotel. Again, absolutely delicious!! Thank you!

    I have had this recipe printed for awhile now but I am finally getting around to making it. The only thing I’m confused about is the can of Rotel. I’m not sure if that’s a thing in the states but I’m not sure if we have that here. I thought maybe it was refried beans but looking at the can, and seeing carbs, I knew it wouldn’t be used in a low carb recipe. In the pictures it looks like tomatoes. SO just wondering what it actually is. Otherwise, can’t wait to try it. Thank you.

  4. Leah says:

    1/2 sausage, 1/2 beef
    At least 6 tbsp taco seasoning (I use homemade, too)
    Cheddar Jack instead of cheddar
    Top with cilantro and avocado/guacamole
    ???

    Really enjoyed this. Added a little extra heat with some diced chili peppers and it came out great.

  6. Brandy says:

    Love this recipe. I used salsa instead of rotel and used taco rice instead of cauliflower rice.

    Taco casserole is awesome. I have made it several times for different family and friends and everyone loved it. Simple to make and tastes like I worked for hours. Thank you, thank you

    This was absolutely delicious
    My favorite taco meal is called a taco bake
    I was craving one but needed a keto Friendly solution. This was quick, easy, and exactly what I was craving! Tastes a lot like my mom’s taco bake!! But without the overload of carbs
    I added queso cheese to top off the meat before I put the cheese on top and the whole family including my picky kids LOVED IT

    This was sooo delicious and my Fiance loved it too! I used Daiya cheddar cheese and mozarella cheese and it worked well with the dish. I ended up mixing the taco meat in with the cauliflower/cream cheese mixture and it was great! I will definitely make again but will probably add jalapeno and green peppers. Thank you for this recipe!

  11. Kayla says:

    How can I convert this to slow cooker? I want to take as a dish to work potluck but need it to stay warm.

  12. Laurie Ginter says:

    Tried this recipe and it was fabulous!

  13. Karen says:

    5 stars
    This tasted delicious. The only problem was 1/8 of the recipe was not enough for a meal for me.

  14. Amber says:

    Can you freeze this or would the consistency of the cream cheese be to weird?

  15. Carrie says:

    This recipe serves 8, so 1/8 f the entire amount would be the serving size. Thank you!

  16. sandy dodson says:

    Could you please tell me what one serving size would be for this I am taking it maybe a cup would really like to know
    Thank you making this tonight for dinner
