Mashed Cauliflower (Keto & Low-Carb)

This post may contain affiliate links. Please read my disclosure and privacy policy.

Cauliflower is one of the world’s most versatile vegetables. Not only does it make a perfect pizza crust and a tasty fried rice, it’s also a surprisingly delicious alternative to traditional mashed potatoes. This Mashed Cauliflower is lower in carbs, higher in nutrients, and tastes amazing!

Benefits of Cauliflower

Mashed cauliflower makes a healthy and satisfying alternative to mashed potatoes. Don’t get me wrong, I still love real mashed potatoes, but if you need to avoid starches (like if you’re following a specific carbohydrate diet or GAPS protocol), or are following another special diet around the holidays, this recipe makes the perfect side dish.

Here’s what I love about cauliflower:

  • Compared to potatoes, cauliflower has less than half the calories per the same 100 gram serving. (source)
  • Cauliflower has only 3 grams of “net carbs” per 100 gram serving, while potatoes have 14 grams of net carbs. (Net carbs = total carbohydrates – total fiber.)
  • Just 1 cup of cauliflower contains 35% of your vitamin C needs for the day. (Based on recommended daily values.)
  • Since it’s a cruciferous vegetable, cauliflower is high in antioxidants, particularly glucosinolates and isothiocyanates, which have been linked to slowing growth of cancer cells.
  • Cauliflower is 92% water, and eating more water-dense and low-calorie is linked to weight loss.

I also love how quickly cauliflower cooks! This is a side dish that is ready in just about 20 minutes from start to finish.

What Does Mashed Cauliflower Taste Like?

Cauliflower is a mild-tasting vegetable, which is why it works so well as Cauliflower Rice, and even as Cauliflower Buffalo Wings. These mashed “potatoes” will taste like whatever you add to them!

I recommend adding a hefty seasoning of salt and pepper, and I also like to pulse a batch of quickly sauteed garlic in for an extra boost of flavor. But, you don’t have to stop there! You can stir in your favorite cheese (my mom always used cream cheese when I was growing up, but now I’ll use soft goat cheese because I prefer the flavor and how it digests easier than cow’s milk).

To keep this side dish vegan, try stirring in some hummus for creaminess! I was inspired to do this after using hummus to make my Vegan Pasta creamy, and the results are unbelievably delicious. You can use store-bought hummus for convenience, or make your own. (Try my Zucchini Hummus if you want a bean-free option.)

How Long Does this Cauliflower Mash Last?

Mashed cauliflower can last up to 5 days in the fridge when stored in an airtight container. Try it with my Vegan Gravy for a totally vegetable-based meal, that’s also dairy-free and gluten-free!

Mashed Cauliflower (Keto & Low-Carb)

Course Side Dish
Cuisine low-carb
Keyword mashed cauliflower
Prep Time 15 minutes
Cook Time 10 minutes
Total Time 25 minutes
Servings 2
Calories 57kcal

Ingredients

  • 1 Medium-sized head of cauliflower , chopped into florets (about 1 1/2-2 lbs.)
  • 1 tablespoon extra-virgin olive oil
  • 6 garlic cloves , minced
  • 1 teaspoon fresh thyme leaves
  • salt and pepper , to taste

Instructions

  • Fill a large saucepan with about an inch of water, and insert a steamer basket. Bring the water to a boil, and add the cauliflower florets. Reduce the heat to a simmer and cover, allowing the cauliflower to steam for 10 minutes, or until fork tender.
  • Drain the cauliflower and set it aside. Return the pan to the heat and add in the olive oil and garlic. Saute briefly, just until the garlic is softened and fragrant, about 2 minutes.
  • Transfer the cauliflower and garlic to the bowl of a large food processor fitted with an "S" blade. Season with salt and pepper, and the fresh thyme. (I start with 1/2 teaspoon of salt and about 5 grinds of the pepper mill.)
  • Process until the mixture is smooth and resembles mashed potatoes. You can add a splash of water if needed, but usually the cauliflower already has enough moisture that you won't need it. Taste and adjust the seasoning, adding more salt if desired. You can also stir in cheese or hummus at this point, for extra creaminess.
  • Serve warm (you can return the prepared mash to the pan to heat up again, if needed) with gravy on top, if desired. Leftovers can be stored in an airtight container in the fridge for up to 5 days.

Notes

This mashed cauliflower dish makes a great base for any of your favorite add-ins. If you prefer cheesy mashed potatoes, try adding 2-3 ounces of creamy goat cheese, or a sprinkling of nutritional yeast for a vegan variation. You could also add in some extra chives and a few spoonfuls of plain goat yogurt for a "sour cream & onion" flavor. The options are endless! Also, be sure to note the serving size on this recipe. One medium head of cauliflower only made enough to serve two people in our house-- we love to heap it onto our plates! If you're serving a bunch of mashed potato fans, you may want to double or triple this recipe, to be on the safe side.

Recipe Notes:

One head of cauliflower makes roughly 2 cups of mash, which only serves about 2 in my household. We love mashed “potatoes!” If you are okay with smaller 1/2 cup servings, this should serve 4 people.

Anything you love to add to mashed potatoes, you can add to mashed cauliflower. You can add yogurt or sour cream, cream cheese, cheddar, bacon, green onions, or chives. For a vegan version, definitely try stirring in some hummus for added creaminess!

This is a great recipe. I love cauliflower! This is what I use when I make my rice for my sushi, too. I pulse it raw, however. Such a great veggie!

Danielle @ Clean Food Creative Fitness

This looks great! I made a total recipe fail one time with mashed cauliflower so I like that this has no liquid in it! I think the recipe I tried was way too watery from what I remember!

the delicate place

i tried cauli mash for the first time in 2009 when i was making a cottage pie recipe from mark’s daily apple. i never looked back! some of my friends had no idea that it was not potatoes! i love to do a coconut curry mash with cauliflower, i love the richness that coconut milk or oil brings to the mashed dish. it’s a staple at my thanksgiving table 🙂

    Abby

    How did you do the coconut curry mash!?!?!

Jen @ Existential Evolution

Finally got around to making your cauliflower pizza recently and it was delish! Wow you’re really laying out a great Thanksgiving spread for us this week. Thanks for sharing the fruits of your labor with us.

kaity @ kaityscooking

i LOVE mashed cauliflower! to get my family who dislikes most veggies to eat it, i first made it with a few potatoes thrown in there and they loved it and each time i decreased the amount of potatoes in it until there was none and they loveee it still

Justine

I tried mashed cauliflower for the first time last week. Loved it!! A new favorite for sure:) I enjoyed how light they were compared to how heavy mashed potatoes normally leave me feeling. Can’t wait to try your version!! Thanks for all your hard work in posting so many recipes this week!! Enjoying them:) I was wondering, do you have any plans for a healthy version of sweet potato casserole? Yum…..

Donna

You can also substitute celery root (cèlèri râve) for the cauliflower to GREAT effect and family commentary….really…try it!! (Low carb/low cal/paleo)..I love this recipe for BOTH veggies!

Claire

I loved this recipe! I prefer this to masked potatoes. Thanks for the recipe.

Claire

Drats, meant MASHED potatoes!

Abby

I’ve also done it by boiling it in a small amount of vegetable broth(depends on how much cauli I put in) but usually fill the pot an inch or two with it. Bring everything to a boil together. It’s really good! And adds a little bit of flavor as well. 🙂

Melodious

While steaming is faster, I prefer to roast my cauliflower before mashing (which means a whir with the immersion blender) after adding a pat of grassfed butter and a splash of coconut milk. Delicious!

Christine

I made this today and it was amazing! I can’t believe it tastes so much like mashed potatoes! Thanks for the recipe!

Linda

I put mine in the Ninja and with NO additional liquids… they always come out looking like MASHED potatoes! I call them Ninja taters!

Kris Simms

Just started on the paleo diet this month and feel so much better! Making this recipe tonite along w skirt steak and chimchurri YUM!!!!!

Aurial

Tip for everyone! Don’t sub raw garlic for roasted garlic.
I’m a garlic fiend and it was way too garlicky. Next time I’ll try the roasted garlic. Otherwise I loved this recipe, super easy and great texture. All of the other recipes I found were full of
Butter or cream!

Maxine

What if I don’t have a food processer. Can I use a mixer?

    Lauren

    You can mash the cooked cauliflower very well with a potato ricer.

Kayla

This is seriously the easiest, most delicious side dish ever! I added 2 tbsp of coconut cream to the mix for a little creamier consistency! I’ll definitely be making this more often!

Cathy

Am wanting to loose weight and should avoid potatoes and any of that starchy food so I definitely will try this recipe… stay tuned for tomorrow after I have tried this.

Joanne

Love the fact that there is no unnecessary butter, cream, coconut oil/milk, or other oil. You simply don’t need it!

Emma

I didn’t know what to do without mashed potatoes, and now I’m so happy I found this recipe! I used sautéed onions, coconut oil, and roasted garlic. Soooo yummy!

Bill

WOW! These are awesome!! I spent 35 years avoiding cauliflower because as a child, an adult told me they were just like mashed potatoes. The circle is now complete 🙂

Marlene

This recipes even got two thumbs up from my picky teenage daughter! Thanks a million 🙂

Thalita

What is the nutrition facts for this recipe?
Thank you!

Jamie

Now THAT was delicious. I don’t have a food processor but I mashed it as best I could and it was awesome. I added a bit of cheese to it and my husband loved it. Maybe it’s time to by a food processor !! Thanks for sharing !!
