With Fall in full swing here, it’s time for all things cozy, comforting, creamy, and secretly healthy?!… Yup, this cauliflower mashed potatoes recipe fits the bill.

This roasted garlic mashed cauliflower is the perfect example of how eating healthy can also make you feel all warm and cozy inside.

Not only is this side super creamy and delicious (I swear, it tastes just as good as boiling potatoes for classic mashed potatoes or making these Instant Pot Mashed Potatoes!) but it’s also secretly low-carb, vegan, dairy-free, and Paleo!! 

This easy mashed cauliflower recipe is the CREAMIEST mash you’ll taste. Your taste buds won’t know what hit them.

Cauliflower, garlic, oil, milk, and herbs as the ingredients for the best mashed cauliflower potatoes recipe.

Ingredients

The simple ingredients you need to make this creamy mashed cauliflower recipe include:

  • Cauliflower. Make sure you get a LARGE head of cauliflower to have enough florets for the recipe. You want to end up with about 5 cups of cauliflower florets. (Learn How to Cut Cauliflower if you don’t already know!)
  • Roasted Garlic. This gives the dish SO much flavor! Start with a head of garlic, and learn How to Roast Garlic and prepare it up to 3 days in advance before making this recipe.
  • Herbs. Fresh rosemary and thyme are used in this recipe, but you can also try adding sage or tarragon. Dried herbs may also be used, just make sure to use  to ½ the amount.
  • Oil. A good quality olive oil or avocado oil will contribute to the taste of this side dish.
  • Milk. In order to get the right consistency, a touch of milk is needed. Regular milk, or a dairy-free option like oat, almond, soy, cashew, or coconut milk works great!

How to Make Garlic Mashed Cauliflower

Below are the steps to make this garlic cauliflower mash recipe at home:

Roast Garlic in Oven

Preheat the oven to 400°F.

Carefully slice the ends of the fresh garlic head off. Drizzle some olive oil over the entire head, then sprinkle some salt over it.

Wrap the garlic in foil and bake in preheated oven at 400°F for 40-50 minutes. 

You can roast garlic in the oven up to 3 days in advance.

Boil the Cauliflower

While the garlic is roasting, you can boil the cauliflower.

Cut the cauliflower into florets and boil the until tender, about 10-12 minutes. Drain the water and dry thoroughly. 

Be sure to dry completely! Any extra water will make the mashed cauliflower soggy instead of fluffy.

Purée in Processor

Add the cauliflower to a large food processor along with the olive oil, roasted garlic, herbs, salt, and pepper. Be sure to remove any skin from the garlic after roasting it. 

A food processor is the best appliance to use, but a high-speed blender, such as a Vitamix, also works greatA potato masher or immersion blender aren’t the best options for this dish.

Purée until JUST smooth. Be careful not to over-purée or it will get too liquidy.

After you finish processing the cauliflower you will want to check the temperature of it. If it is not warm enough, add the creamy cauliflower purée back to the pot over medium-low heat and warm it up to your desired temperature.

Meal Prep and Storage

  • To Prep-Ahead: Roast the garlic, and wash and cut the cauliflower up to 3 days in advance. Keep refrigerated until ready to use. 
  • To Store: Place leftovers in an airtight container in the refrigerator for up to 3-5 days. 
  • To Freeze: Seal tightly in a freezer-safe airtight container and freeze for up to 4-6 months. 
  • To Reheat: Warm on the stovetop or in the microwave until heated through. Note that the cauliflower will begin to separate from the liquid and will need to be stirred before serving.

How long to boil cauliflower for mash?

When making a mash, boil cauliflower for no more than 10 to 12 minutes. Too long and it will get quite mushy and you’ll lose your fluffy, thick texture.

How to thicken cauliflower mash?

To thicken your cauliflower mash, try mixing in milk, cheese, butter, or a vegan butter substitute. If your mashed cauliflower is a little runny, there are a few things you can do for next time. Make sure to drain all the excess liquid from the cauliflower before puréeing, or use a steamer basket instead of boiling. You can also try roasting the cauliflower instead of boiling it for a firmer mash.

Is mashed cauliflower healthy?

Mashed cauliflower, by itself, is a healthy, low-carb side dish. Mashed cauliflower packs more nutrients than mashed potatoes and has fewer calories, less starch, and lower carbs. Be careful how much you add to it, however. Butter, cheese, and cream all contribute calories.

Expert Tips and Tricks

  • Boil until tender. You definitely want the cauliflower to be soft so it blends well. 
  • Dry thoroughly. Extra moisture will make the consistency too runny. 
  • Roast it real good. The garlic should have a nice golden to dark brown hue for the most flavor. You can use fresh, but it will have a more pungent taste.
  • Dress it up. Garnish with a drizzle of olive oil, a sprinkle of fresh herbs, and additional roasted garlic cloves.
  • Change the flavor. Try a mix of different herbs and spices each time you make it.

Notes

  • Do NOT use a Vitamix or high-speed blender.  You will end up with overly-blended and runny cauliflower mashed potatoes.
  • Roast a head of garlic in the oven: Trim the ends, drizzle on 1 tablespoon of oil, sprinkle with salt, wrap in foil and then bake at 400 degrees for 40-50 minutes. You can do this up to 3 days in advance and store in the refrigerator until ready to use.
  • Prep-ahead: The mashed cauliflower can be fully made ahead and stored in the fridge. Just reheat it on the stovetop or in the microwave, stirring occasionally for even heating.
  • Storage (refrigerator): Store leftovers in an airtight container for up to 4 days. Reheat on the stovetop over low heat or in the microwave, adding a splash of milk or broth if needed to loosen the consistency.
  • Storage (freezer): Let the mashed cauliflower cool completely before transferring to a freezer-safe container. Store for up to 1 month. For best texture, thaw in the fridge overnight, then reheat on the stovetop, adding dairy or seasoning as needed.
