This mashed cauliflower recipe is unbelievably rich, creamy, and over-the-top decadent while still being perfect for your keto Thanksgiving dinner. It's a recipe the whole family can and will absolutely love.

Ingredient Notes
- Cauliflower - This is the main ingredient in this recipe so make sure you use fresh cauliflower. Frozen cauliflower won't give you the right taste or texture.
- Garlic - Use fresh garlic cloves. I do not recommend substituting with garlic powder.
- Vegetable Broth - Feel free to use your favorite storebought option or you can make your own veggie broth at home.
- Vegan Butter- Look for a high-quality non-hydrogenated vegan butter. I recommend either Earth Balance or Miyoko’s.
- Non-Dairy Milk - Any unsweetened neutral flavored milk such as soy, cashew, or macadamia nut milk will work.
Recommended Equipment
You will need a good chef’s knife, a large pot, a food processor or blender, cutting board, and basic kitchen utensils. (<<affiliate links)
Step-by-Step Instructions
Step one - Chop and Cook the Cauliflower
Chop the cauliflower into small, even-sized florets.
In a large pot, bring 4 cups of vegetable broth to a boil. Add the chopped cauliflower and whole garlic cloves and boil for 15 minutes, until the florets are easily pierced with a fork.
Strain the cooked cauliflower and garlic through a fine mesh strainer.
Step Two - Blend the Cauliflower
Transfer the cauliflower and garlic to a blender or food processor along with your remaining ingredients. Blend for 1-2 minutes until you have the consistency of mashed potatoes.
Pro Tip: Depending on the size of the cauliflower, you may need to add 1-2 tablespoons of non-dairy milk while you process. Add just about 1-2 teaspoons at a time until you get the right consistency.
Serve immediately with vegan butter, fresh chives, salt, and pepper.
Serving and Storing
Serving - Serve warm with freshly ground pepper, butter, fresh chives, and some vegan parmesan.
Storing - This recipe is best fresh. I don't recommend making more than you intend to serve. If you do have leftovers, store them in an airtight container in the refrigerator for up to 24 hours.
Tips and Tricks
- If you would prefer a thicker consistency (plus less mess!), you can use a potato masher or immersion blender.
- Taste and adjust seasonings as you please. This recipe is merely guidelines as the seasonings will depend on the size of your cauliflower.
- I recommend Violife Parmesan for this recipe. I add about ¼ cup of this parmesan to the cauliflower mash as well as on top it. It is creamy, melty, and tastes exactly how I remember parmesan to taste. If you don't have access to Violife, you can make your own parmesan or omit it altogether.
- Consider adding this to your holiday meal. Serve it with mushroom gravy.
Cauliflower vs. Potatoes
This keto cauliflower mash is rich, creamy, delicious, and taste very similar to mashed potatoes. Potatoes and cauliflower are not that different in texture, neither have much taste, and both absorb the flavors around it.
But when it comes to the two, cauliflower is the much healthier option.
- Cauliflower is the low carb option. Potatoes have a glycemic index of over 75 making it a high-glycemic food. Cauliflower, on the other hand, ranks between 0-15 on the glycemic index. This is important to keep in mind for people with diabetes or are pre-diabetic. And I recommend all vegans consider low glycemic options as our diet typically tends to be high in carbs.
- 1 cup of potatoes is 115 calories compared to the 27 calories for cauliflower.
- Cauliflower is rich in antioxidants, important vitamins and minerals, and many nutrients.
Don't get me wrong, I LOVE mashed potatoes. But as I get older, I do need to consider healthier alternatives and for that reason, I am grateful for this alternative.

Hello Sarah, I have been vegan for over 50 years now but also have the added difficulty of now being pre-diabetic ! Trying to combine both dietary requirements is not easy as most 'Keto' foods contain egg. Bread is particularly difficult.
I use Kohlrabi in place of potatoes in most dishes, roast, boiled or chipped, and they are delicious, if expensive, but they are not good as a mash. I tried this recipe yesterday and Oh Boy, what a treat!! I am going to try it next as a topping for a vegan Cottage / Shepherd's pie !
Thank you so much for your wonderful ideas, I have tried many of your recipes and am so grateful for the helpful insight.

Earth Balance has palm oil. Miyoko's would be better.
Oldmanken says
Easy and healthy.
Melanie says
Will this keep in the fridge for a few days?
Sarah says
It will but it will be at it's best when it's freshly made. So I wouldn't recommend making it in advance for an event.
