This cauliflower mash tastes so good, our family prefers it over mashed potatoes! Cheesy mashed cauliflower is the perfect side dish for your low carb meals.

We love mashed potatoes, but we also love mashed cauliflower. We took this favorite recipe and turned it low carb. A much lighter result, while tasting oh so delicious and leaving you feeling good!

About this Recipe

Years ago, we published a cheesy mashed potatoes recipe. It's a family favorite served over the holidays. A couple of months ago, we had friends over for dinner who's son is diabetic. Keeping low-carb in mind for his specific diet, I altered the mashed potato recipe to create this cauliflower mash as a side dish with our Italian Meatloaf.

The cauliflower mash turned out SO GOOD that most people wanted seconds of it more than the actual potatoes! So I retested the recipe several times with cauliflower and every time it turned out fantastic.

Ingredients

(full printable recipe at end of this post)

Below are the ingredients you need to make this mashed cauliflower recipe.

ingredients for mashed cauliflower recipeGrocery List:

  • Cauliflower - You need a large cauliflower that is about 3 lbs. If there is just a 2 lb medium head, it will work.
  • Garlic - I boil the cauliflower with minced garlic for extra flavor. For this, I like the convenience of jarred minced garlic, but you can use fresh cloves.
  • Half and half - We use half and half for our cream in this recipe to keep it low carb. You can use any standard milk or cream you prefer. (I do not recommend almond, oat or coconut milk.) Or even sour cream!
  • Unsalted butter - You control the amount of salt in this recipe, so use unsalted butter. If you only have salted, just omit or reduce the amount of salt.
  • Cream cheese - This is a big factor is making the cauliflower taste good, especially to those who may not necessarily like cauliflower. Try to remember to set this out ahead of time to come to room temperature.
  • Egg - This only takes one large egg, just to get that souffle texture.
  • Mozzarella - Half will be shredded, half will be diced into small cubes. So, grab a block, you'll use 4 ounces total.

Top Tips and Tricks

Cheese: Keep the cheese cold in the fridge until its time to dice it or shred it. It is much easier to slice and shred cold cheese.

Double: You can easily double this recipe and bake in a 9x13-inch pan. Or, double it and bake in two 8x8-inch pans so you have one to share!

Make-ahead: This cauliflower mash can be assembled and baked the day before, then reheated in the oven the next day.

Variations

  • Try adding cooked chopped bacon for extra loaded flavor.
  • Don't like mozzarella? Switch it up with cheddar cheese or another of your favorites.
  • Short on time? Stir in the cheese, let it melt in the hot cauliflower and serve without baking.

Is mashed cauliflower bad for you?
Cauliflower is a great substitute for mashed potatoes and offers a lower calorie option. This mashed cauliflower recipe is loaded with cheese, so like any recipe I post, everything in moderation.

How do you keep mashed cauliflower from being watery?
This mashed cauliflower is not watery as long as you drain the cooked cauliflower before adding to the blender.

Does cauliflower really taste like potatoes?
Cauliflower alone does not taste like potatoes, but it has such a mild flavor and the consistency of it blended into the cheese creates the mashed potatoes texture and taste.

Storage and Leftovers

Store: Any leftovers of this cheesy mashed cauliflower dish should be stored in an airtight container in the fridge for up to 5 days.

Reheat: This reheats very easily in the microwave. I wouldn't even bother turning on the oven, although you can.

Freeze: I do not recommend freezing this dish. Too much water content.
