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!

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!
