My Mashed Cauliflower is the perfect low-carb stand-in for mashed potatoes at your Thanksgiving table. This 3-ingredient recipe is the easiest you’ll ever find and it’s especially amazing when smothered in the wholesome juices of my low-carb Gravy recipe.
The Best Mashed Cauliflower Recipe
I’ve been making these mock mashed potatoes since 2007. I love that they’re low-carb and gluten-free, the best of both worlds. For this same reason, my Cauliflower Rice recipe is in regular rotation in our house. We load up on broccoli and kale too. All of these superfoods contain a very special ingredient!
Eat Cruciferous Vegetables to Activate Nrf2 Pathway
Cruciferous vegetables including cauliflower, broccoli, and kale contain a compound called sulforaphane that activates the Nrf2 pathway. This defense mechanism protects the body against oxidative stress that can result in health issues ranging from cancer to neurodegeneration to mood disorders.
Supplements to Activate Nrf2 Pathway
You can also upregulate the Nrf2 pathway with supplements. I’ve been taking DIM since my MS diagnosis in 2006. I also take a supplement called Meriva which contains curcumin, the substance derived from turmeric. If supplements aren’t for you, try my Turmeric Root Milk recipe. It’s high in curcumin as well as selenium, a mineral that’s important for the proper function of several metabolic pathways.

I love mashed cauliflower as well! I make it with coconut oil and coconut milk, to give it a creamy texture. We also LOVE your cauliflower rice recipe- so good!
Yes, could you please share your gravy recipe?

Celeriac puree is a amazing substitute for mashed potatoes. Its prepared in exactly the same way as your recipe above. I’ve only used butter (lots) and salt with it, but other oils or fats might also work. Its especially fantastic with game. Its borderline SCD – some tolerate it, some don’t.

Yes, celery root is a great potato substitute! For those who eat dairy…a little butter and cottage cheese mashed with the celery root is very good.

I like to add some cream cheese to the mashed cauliflower.

I’ve made cauliflower “mashed potatoes” several times (I found the recipe on allrecipes.com). I love to add a couple gloves of garlic in with the cauliflower while steaming it and pureeing them right in with the cauliflower.

One of my favorites! I use olive oil and add a big bunch of chopped parsley, too.

Thanks for making it a dairy-free recipe! All the other mashed cauliflower recipes I found have sour cream or cream cheese or such in it. I will try this one soon!
