Would I ever totally give up mashed potatoes? No. But it’s always good to have options. This keto roasted cauliflower mash is an easy side dish that has added flavor because it’s not just plain ole boiled cauliflower that we throw in here.

Nope. We roast it first. Like I’ve mentioned in previous posts, roasting cauliflower is the way to go. Cauliflower still seems to be having a moment, so I’m going to go with it.

If you’re looking for a tasty low-carb side side for your holiday table, this is it.

I always like to add herbs to mashed potatoes, so I did the same with this mashed cauliflower recipe. A little cream and butter make it nice and silky. If you don’t need this recipe to be keto, feel free to use milk… I have made this recipe with skim milk before successfully.

How to make roasted mashed cauliflower

Roast cauliflower florets at 450F for 20-25 minutes with the oil and seasonings.

Add butter and cream to a pot over medium-high heat when the cauliflower is almost finished roasting.

Once the cauliflower is cooked, add it to the pot. Using an immersion blender, you can purée it right in the pot. Purée until it’s as silky as you wish. Make sure to season it well and add the fresh parsley if you wish.

It is really easy to make keto mashed cauliflower.

Prep: 5 minutes
Cook: 25 minutes
Total: 30 minutes

Ingredients 

  • 1 head cauliflower separated into florets

    Yummy! I was craving mashed potatoes but don’t have potatoes on hand so tried this cauliflower recipe. Delicious! I’ll make it again!

    Made it today to pair with tenderloin but added a medium baked potato and some roasted green onions to a very large cauliflower to give it more of a mashed potato consistency. Everyone loved it and loved that it was primarily cauliflower. Will definitely make it a staple with nice meals.
