Keto Roasted Cauliflower Mash without Dairy

What is cauliflower mash?

Cauliflower mash is a favorite low carb swap for mashed potatoes. It’s a keto diet staple for many potato lovers who are craving their beloved starchy root vegetable who need an alternative with fewer carbohydrates.

There are a variety of different ways to prepare the cauliflower for cauliflower mash. Mostly, you just need to cook the cauliflower until it is tender enough to blend. You can boil it, steam it, or microwave it, but I find those methods leaves the cauliflower a bit on the watery side once it’s all mashed up.

I much prefer roasting the cauliflower for cauliflower mash! Any excess moisture is cooked right out of the cauliflower, giving the roasted cauliflower mash the perfect texture and making a much more believable potato replacement. It’s not watery at all! You can blend it up in a food processor for a lump-free “mashed potato” or if you prefer a lumpy mashed potato, as do I, you can manually smash it up with a potato masher.

How to make dairy-free cauliflower mash creamy?

Many cauliflower mash recipes rely on dairy to get the creamy copycat texture of mashed potatoes. But I have to tell you a little secret, even when I was a total carbivore and made real mashed potatoes, I never used dairy. No heavy cream, milk, or sour cream. Instead, I used mayonnaise to create the perfect creamy mashed potatoes. Dead serious! The mayonnaise gives the potatoes this luxurious, velvety texture without any dairy whatsoever.

So naturally, when I make cauliflower mash, I use mayo too! If you are dairy free, and even if you aren’t, I highly recommend you give the mayo trick a shot if you’re aiming for a creamy texture!

Ghee and olive oil are also excellent dairy-free additions to cauliflower mash; however, they don’t significantly contribute to the creaminess of the dish.
