These Cauliflower Mashed Potatoes with Truffle Oil are a special treat when you’re looking to dress up your mashed potatoes. Cauliflower is the secret ingredient to making these a little bit healthier.

I made these special Cauliflower Mashed Potatoes with Truffle Oil for Easter this past weekend, and it was such a treat. Using truffle oil is definitely a trick since almost anything tastes good with it. I had a bottle leftover from the holidays that I’d bought from Costco’s, but you can find small bottles of this specialty item at Home Goods for a discount.

I’ve been mixing cauliflower and potatoes together for mashed potatoes to make them healthier – think of it as two vegetables in one. I know some people use 100% cauliflower and call it mashed potatoes, but I find the consistency lacks the starchiness that people expect when they take a bite of mashed potatoes. You don’t need a lot of potato to get the right consistency, but I’m all about making sure my kids eating healthy, while loving every bite.

I use a little butter from grass-fed cows, which is supposed to contain the X Factor according to Dr. Weston Price (now believed to be vitamin K2). According to the Weston A Price Foundation, “Vitamin K2 is important for the utilization of minerals, protects against tooth decay, supports growth and development, is involved in normal reproduction, protects against calcification of the arteries leading to heart disease, and is a major component of the brain.”

These mashed potatoes would go perfectly with my Balsamic Glazed Roasted Vegetable Turkey Meatloaf, Barbecue Meatloaf Muffins, or Easy Herb Spiced Roasted Chicken.

  1. I love that this is a mix of potatoes and cauli so you still get that comfort food feel but without all the calories!!

  2. Yum!!! I’m going to have to try this! My husband and I made cauliflower mash a few months ago but my husband was not a fan. He’d probably never notice the cauliflower in this dish! 😉

  3. Beautiful! Jeanette this is one fabulous recipe. I love that you combined both cauliflower and potatoes in this mashed side dish treat with truffle oil! Genius. Thanks for sharing. Pinning (of course)!

  4. I have added parsnip and rutabaga to mashed potatoes, which is delicious. Now I need to try mashed cauliflower. Love the addition of Truffle oil, sounds delicious! Yum, Hugs, Terra

  5. What a perfectly healthy side dish! This is awesome!

  6. Hi Jeanette
    This is a very nice way to eat masdhed potatoes, I usually add garlic and olive oil to mine.
    Also I like the addition of truffle oil which certainly imparts a distinctive flavor to this dish.

  7. I love using cauliflower in the place of mashed potatoes!

  8. This looks both healthy and delicious! What more could anyone ask for from a side dish? Love it! Thanks for sharing!

  9. This is such a great recipe now that I’m on a diet – will definitely have to try it!

  10. Love this! I make mashed cauliflower at least once a week and can not believe I haven’t thought to put truffle oil in it. Such a great idea!

  11. I adore mashed cauliflower – but what a wonderful addition with the truffle oil!

  12. Cauliflower is my favourite and I can eat this veggie every day! This looks really creamy and smooth.

  13. Mashed cauli is good and mashed potatoes are good but with truffle oil? That takes these over the top! Wow, Jeanette!

  14. Jeanette Jeanette says:

    Thanks everyone – I love using cauliflower to make recipes healthier. A little truffle oil definitely makes these special.

  15. Those are the fluffiest, most buttery looking mashed potatoes I’ve ever seen, Jeanette! Love the addition of cauliflower for a healthy kick!

  16. These look so creamy and amazing. I had no knowledge regarding vitamin k2. That’s pretty cool,

  17. This is really creative mashed potatoes that I will DEFINITELY want to give it a try myself! Love cauliflowers but never thought of this idea. Can’t wait – looks soooo creamy and yummy!

    • Jeanette Jeanette says:

      Nami – fortunately my kids like cauliflower and I’ve found it’s an easy way to make dishes healthier where I might typically use potatoes.

  18. Interesting! My sister make a mashed cauliflower with butter recipe over Thanksgiving last year. It was creative and healthy, but lacked the richness that I was used to with mashed potatoes. I like the idea of adding a bit of potatoes to this!

  19. Love the idea of adding cauliflower to your mashed potatoes! The truffle oil is such a nice addition. This looks so fluffy and creamy – love that it’s healthier too!

  20. Hello there, just found your blog on a tangent, searching for sous vide recipes.

    I wanted to share with you a slightly different take on mashed cauliflower that results in a puree as smooth and as perfect in texture as a “real” potato concoction. I am not interested in low carbing or anything like that, but simply love the lighter flavor of cauliflower as a side dish.

    if you want to take a look, here is a link to the recipe as I published a few years ago:


  21. I love cauliflower mash and adding a little truffle oil sounds like the perfect way to dress it up!

  22. I love that you do half and half, and the truffle oil here really puts this over the top.

    • Jeanette Jeanette says:

      Shaina – I find the half and half works for my kids because it still has the potatoe-y consistency while upping the nutrition. And a little truffle oil goes a long way.

  23. Hello I came across this very delicious looking recipe just a few seconds ago. I have long heard that potatoes and cauliflower are an excellent combination. I would like your permission to re-publish this recipes and possibly others on my website. I am asking permission so as to not overstep any internet protocol. All of my contact information is correct. Thanks, I look forward to hearing from you.
