This mashed cauliflower is whipped with heavy cream, parmesan, and loads of butter, for a indulgent flavor that doesn't taste low carb… even non-keto picky eaters grab for seconds. If you have kids who don't love vegetables, especially cauliflower, this recipe is a great way to get them going back for more.

Mashed Cauliflower Ingredients

First assemble the following ingredients:

• Head cauliflower (1 large, cut into florets) – Serves as the low-carb base that becomes creamy and potato-like once cooked and blended.
• Unsalted butter (4 tablespoons) – Adds rich creaminess and depth without overpowering the other flavors.
• Garlic powder (1 tsp) – Delivers a subtle garlic aroma and warmth without needing fresh cloves.
• Italian herbs (1 tsp) – Brings a savory, herb-forward note that brightens the mash
• Garlic (6 cloves) – Provides bold, punchy garlic flavor for noticeable depth.
• Heavy cream (3 tablespoons) – Adds silky richness to achieve a smooth, indulgent texture.
• Parmesan cheese (¼ cup) – Contributes sharp, savory cheesiness and a touch of tang.
• Salt and black pepper (to taste) – Seasoning to balance the creamy, savory components.
• Chopped chives (for garnish) – Finishes with a bright, oniony note and a pop of color.

Steps to Make Keto Mashed Cauliflower

Cook Cauliflower. Bring a large pot of water to boil on the stove, add cauliflower. Boil for 15 minutes until cauliflower is soft to the touch. Drain cauliflower and cover with a lid while butter is prepared.

Head Dairy. In the same pot, heat the butter over medium high heat. Sauté garlic until softened and fragrant (about 2 minutes).

Mix and finish. In a stand mixer, or with a large bowl with a hand mixer, add cauliflower, heavy cream, seasonings, melted butter and garlic. Mix on high until smooth. Top with diced chives and serve immediately!

Kitchen notes

Drain Cauliflower. Cauliflower gives off a LOT of moisture – we like to set it in a cheesecloth and squeeze out as much liquid as possible before mashing. This will help give a good thick consistency, instead of being overly watery.

Mix Until Smooth. Since cauliflower doesn't have the starched potatoes do, we're not running a risk of overworking the cauliflower – it won't turn gummy if you mix it more – so if you want no lumps, go for it!

Undercook Cauliflower Slightly. Cauliflower should bee tender to the touch when pressed with the tines of a fork – but not so soft it smushes. Leaving cauliflower in boiling water too long will make it mushy and watery.

Make it Ahead. Luckily, this cauliflower recipe actually tastes better from reheating – so make it a day early, then refrigerate in an airtight bowl and reheat by adding to a well-greased baking dish (or cover it in parchment paper), covered with foil.

Keto Mashed Cauliflower FAQs

Can we make this dairy-free or lower in fat?

Yes. Use olive oil or dairy-free butter instead of butter, and substitute heavy cream with unsweetened almond milk or coconut cream. Omit or replace Parmesan with a dairy-free cheese if desired.

Can we use fresh garlic instead of garlic powder?

Absolutely. You can use 2–3 minced garlic cloves (or more to taste) in place of the garlic powder, and you can still add the diced garlic for extra punch.

Is Parmesan essential, or can we skip it?

Parmesan adds a sharp, savory note, but you can skip it or substitute with a dairy-free cheese if needed. Nutritional yeast is another dairy-free option for a cheesy vibe.

Can we freeze leftovers?

Yes. Freeze in an airtight container. Reheat gently on the stovetop or in the microwave, adding a splash of cream or milk to restore creaminess.

How do we reheat the mash without losing texture?

Reheat on low heat, stirring in a bit of cream or butter as needed until creamy again. A quick stir with a fork or immersion blender can restore fluffiness.

How long will leftovers keep in the fridge?

About 3–4 days when stored in an airtight container.
