As I’ve discussed at length, we are big Taco Tuesday fans around here. I’ve found plenty of options to make our favorite taco recipes keto-friendly, including keto Spanish rice! Cauliflower is a great substitute for rice and you can pretty much find riced cauliflower – both frozen and fresh – at your supermarket. I buy riced cauliflower in bulk at Costco, because we use it so often as a substitute for rice or potatoes in many of my recipes.
I love to serve this keto Spanish rice on the side or in my keto tacos and burritos. Topped with some full fat sour cream and extra cilantro, this recipe is sure to become a keto taco Tuesday staple in your house as well! I usually use bone broth instead of regular chicken broth – the added collagen and nutrients are beneficial for gut health and anti-aging. I love the Kettle & Fire brand best, however there are plenty of bone broth options on the shelves now or you can make your own homemade bone broth in a pressure cooker or Instant Pot.
If you prefer to rice your own cauliflower, that works too – just take a full head of cauliflower, break it apart and give it a few gentle spins in your food processor. If you opt for frozen riced cauliflower, just make sure to drain it well and squeeze out any excess moisture in a tea towel or kitchen towel for the best results!
