These cauliflower mashed potatoes are a low-carb side that doesn't taste like one—and that's the whole point.

This mashed cauliflower recipe is creamy and comforting—and it tastes remarkably like mashed potatoes. Maybe it’s just my eyes playing tricks on me, but it really does! Plus, it’s easier to make, healthier, and lower in carbs. But don’t make it solely for those reasons​; this purée is delicious in its own right. When my friend Heather tested the recipe, she texted me, “OMG so good, just licked the bowl of my Cuisinart.”

This cauliflower purée makes a fantastic side dish to many comfort foods—think classic meatloaf or turkey meatloaf, onion-braised beef brisket, or easy BBQ boneless short ribs.

What You’ll Need To Make Mashed Cauliflower

Ingredients including chicken broth, sea salt, and thyme.
  • Cauliflower – Choose a firm, white head free from blemishes for the freshest flavor.
  • Chicken broth – Adds depth and helps cook the cauliflower until tender.
  • Salt and freshly ground black pepper – Enhances and balances all flavors in the purée.
  • Unsalted butter – Adds richness and a creamy texture.
  • Fresh thyme – Lends a subtle woodsy and earthy flavor.

Make-Ahead & Freezing Instructions

Prepare the mashed cauliflower as directed, then cool and refrigerate in an airtight container for up to 3 days. When ready to serve, reheat gently on the stovetop over low heat, stirring occasionally, or microwave in a covered dish, stirring every minute. For longer storage, freeze for up to 3 months. Thaw overnight in the fridge before reheating.

    I never go back and give a review on food recipes. This recipe is an exception. It truly is outstanding. It was great with fish. I could have it every night.

    I retired this year, so I am into cooking now, and just a little annoyed I did not find this recipe 50 years ago.

    I. really liked the addition of steaming with broth rather than water. I think this added a lot of flavor . Since I am dieting, I made the following changes . I reduced the butter from 3 tablespoons to 1 and added one wedge of light laughing cow cheese which is only 35 calories
    also puréed some fresh parsley Into the mix. Delicious,

    This is a wonderful side dish…and so easy to prepare! Will become a go to for mashed potatoes. I needed to add an additional tablespoon of broth in the processor to get everything smooth. Thank you!

    Hi Jenn, I make this ALL the time for family and friends and it’s such a winner! However, this time I have a make-ahead question… if I make tonight (Wednesday) to serve on Easter (Sunday), do you think it will stay fresh in the fridge for a few days, or do I have to freeze? What is the best way to reheat? I’ll wait to add the thyme in until I reheat since I’ve learned the herbs turn a black color and can be a bit off-putting when I add them and then freeze/microwave later… Many thanks for your advice!

    • Glad you like it Allison! You can definitely make this a few days ahead and refrigerate. Just reheat it in the microwave before serving.

  • Would fish go with this recipe?

    • Sure- the cauliflower is really mild tasting so it could be paired with most anything. I think fish would be a nice choice.

    Yum! Made it as directed, and it was delicious!

    This is awesome. Used a stick blender instead of a food processor and with a little added stock, it was a perfect consistency. Will vary the herbs to get different flavors to accompany various proteins.

    I have been learning to eat cleaner and find healthier options to my comfort foods. This cauliflower purée was DELICOUS! Perfect substitute for my beloved mashed potatoes! Totally would recommend this.
