Low Carb Taco Bake
This low carb, Keto-friendly casserole comes together quick and easy. The most important step is to brown your cauliflower rice. If cauliflower-rice isn’t toasted it tends to be soft and kind of soggy. Cook your chicken however you prefer, I usually poach it. Then just mix and bake.
The toppings are what really make this dish. Avocados, olives, lettuce, tomatoes, sour cream and cilantro to start. Add any other low carb topping you prefer. You could even crunch up some low carb tortilla chips as a topping.
This is more of a low carb diet recipe rather than strict Keto.

Made this for the week and it’s great!
Adjustments I made:
I used 4 cups of cauliflower rice because the frozen cauliflower rice I get at my grocery store comes in 2 cup bags.
I put some Tony’s Creole seasoning on the chicken and then threw it in the oven at 365 to cook.
While that was going, I cooked the cauliflower rice in a sauté pan, and let it get nutty. Meanwhile, I put a can of rotel tomatoes in a large mixing bowl, as well as a drained can of sliced olives, and a drained and rinsed can of black beans.
Once the cauliflower rice was done, I added that into the bowl, and then when the chicken was done, I cut it up and added it to the bowl. I added in the taco seasoning, and then the shredded cheese. I prefer the shredded cheese mixed in, because if it’s just on top, it tends to just dry out.
I mixed everything up in the bowl, and then put it into the casserole dish and spread it all around. I then cut up 2 avocados and diced them and put the pieces around the top.
Once it was done, I topped a serving with some salsa and light sour cream.
Excellent dinner!
Thanks for all the tips!
