Can a Cheesy Low Carb Cauliflower Mash be better and more delicious than mashed potatoes? It sure can! This creamy cheese cauliflower mash is made with gruyere cheese, roasted garlic, rosemary, heavy cream and butter. How can it not be better?

Jump To:
I loved mashed potatoes but as a diabetic I need to seek out an alternative that won't spike my blood sugars but still tasted just as good, like this keto mashed cauliflower.
After experimenting with several variations I settled with this version of keto cauliflower mashed potatoes because it's super simple to make and is just as good, if not better than the usual mashed potatoes. This healthy mashed cauliflower recipe goes great with thanksgiving turkey or my Ginger Braised Chicken Thighs.

🥘 Ingredients Used
I used a head of cauliflower for this mashed cauliflower recipe along with the following:
- Gruyere Cheese: gives it a reich, creamy, nutty and salty flavour and is one of my favourite cheeses next to Comte
- Roasted Garlic: roasting the garlic removes the pungent flavours and bring out the nuttiness.
- Rosemary: a little rosemary goes a long way giving this dish a peppery woodsy flavour
- Heavy Whipping Cream: adding more creaminess to this recipe making it extra rich
👨🏻🍳 Steps to make this recipe
How to make cauliflower mash?
STEP 1: Cut the tips off of 4 garlic cloves and wrap them in tinfoil with a teaspoon of olive oil and a dash of salt and pepper. Roast in the oven on a baking sheet at 300°F for around 40 minutes. Once removed from oven allow to slightly cool before squeezing the garlic out of the skin for the mashed cauliflower.

STEP 2: Bring a large pot filled with water to a boil and place bite sized cauliflower florets in the water. Allow to boil for 20 minutes or until fork tender. Strain cauliflower and then place back in the pot with 2 tablespoons of butter.

STEP 3: Add the heavy cream, rosemary, salt, gruyere cheese and roasted garlic. Mash until creamy and smooth.

STEP 4: If any remaining moisture allow to evaporate by cooking on medium heat for a few minutes. Add more cheese for the desired consistency. Place in serving dish and top with a drizzle of olive oil, chopped parsley and chili pepper flakes.

👨🏻🍳 Substitutions and Variations
There are many variations of mashed cauliflower:
- Vegan and Dairy Free - vegan butter and coconut cream can replace the dairy in this recipe
- Fried - allow the mash to cool and roll into 2 inch balls, dredge through some pork rind crumbs and air fry for 10 minutes
- Pesto - add a tablespoon of pesto to the mash to give it a more unique flavour
- Cheese - use your favourite cheese in this dish, cheddar and chives also go well in a cauli mash.
- Roasted Cauliflower - roasting the cauliflower in the oven and then mashing with the ingredients give it more of a nutty flavour profile and is a great alternative to boiling.
- Whipped - for a more cauliflower puree type mash you can whip the cauliflower using an electric mixer
- Cauliflower Rice - If you only have cauliflower rice on hand you can steam the cauliflower rice and then mash with the same ingredients.
This recipe is also Gluten Free.

💭 Frequently asked questions
If you did not strain the water enough or added too much liquid the mash may turn out watery. To compensate allow to cook on medium to allow to evaporate. You can also add more cheese and spice to help dry it out a little more. Some grated parmesan or cream cheese will help thicken it up as well.
