About this Recipe
Years ago, we published this cheesy mashed potatoes recipe from my sister-in-law. It's a family favorite served over the holidays. A couple of months ago, I had friends over for dinner who's son is diabetic. Keeping low-carb in mind for their son's diet, I served our Italian Meatloaf recipe and wanted to have mashed potatoes alongside. So I made the cheesy mashed potatoes dish, but made half with potatoes and half with cauliflower.
The cauliflower mash turned out SO GOOD that most people wanted seconds of it rather than the actual potatoes! So I retested the recipe several times with cauliflower and every time it turned out fantastic.
Ingredients for Cauliflower Mashed Potatoes
(full printable recipe at end of this post)
Below are the ingredients you need to make this mashed cauliflower recipe.
- Cauliflower - Grab a large fresh cauliflower that you'll cut into florets. A large cauliflower will be 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 3 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.)
- 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.

Your Questions Answered
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 covered 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.
For this recipe, we use a high powered blender. You can also use a food processor or just a hand mixer if that's what you have.
