Beef Taco Casserole

We love taking our favorite recipes and making them low-carb! Rice is a no-no in the keto world, but cauliflower rice is a perfect substitution! Healthy, low-carb, and easily seasoned, cauliflower is a multi-purpose superfood that’s inexpensive and available year-round, so it makes sense to add it to your eating plan! And it goes perfectly with this savory beef taco casserole.

Low-Carb Ingredients!

RICE Our beef taco casserole recipe is made with cauliflower rice for the best low carb rice replacement out there! Add some seasoning like cumin and a few jalapeno peppers for extra spice!

GROUND BEEF Use full fat, medium or lean ground beef. Regular full fat tend to have the best flavor, and it’s not forbidden in low carb recipes!

BELL PEPPERS Add an extra layer of texture and flavor to the rice!

DAIRY A topping of eggs and a whole lotta cheese make this taco casserole so full of flavor!

SEASONINGS Here’s our fave Keto taco seasoning recipe. Make extra and keep it in a shaker jar to season everything from chicken to fish or make a spread for low-carb wraps by mixing it with cream cheese! Got leftovers? Taco casserole is an easy way to use up leftovers like chicken, tomatoes, even chopped up broccoli or zucchini!
