This low carb 4-ingredient garlic cauliflower mash is my family’s new holiday obsession. My grandma used to swear she’d never give up her buttery mashed potatoes, but once she tried this rich, velvety cauliflower version, she asked for seconds and the recipe. You get all the cozy, creamy comfort of classic mash with a lighter, low-carb twist, and it still feels special enough for the holiday table or Sunday dinner.
Serve this mash just like you would mashed potatoes: piled high in a warm white serving bowl with a few extra pools of melted butter on top. It’s perfect alongside roast turkey, chicken, meatloaf, or a simple skillet steak. Spoon gravy over it if you like, or keep it simple with extra roasted garlic on top. Add a crisp green salad or roasted green beans to round out the plate, and you’ve got a comforting, balanced meal that feels holiday-worthy any night of the week.
4-Ingredient Garlic Cauliflower MashServings: 4
Ingredients
1 large head cauliflower (about 2 to 2 1/2 pounds), cut into florets
4 tablespoons unsalted butter, plus more for serving if desired
3 to 4 cloves garlic, peeled
1/3 cup heavy cream
1 teaspoon kosher salt, plus more to taste
Directions
Prep the cauliflower: Rinse the cauliflower, remove the leaves and core, and cut into medium florets so they cook evenly.
Cook the cauliflower and garlic: Place the cauliflower florets and whole garlic cloves in a large pot. Add enough water to cover and sprinkle in 1 teaspoon kosher salt. Bring to a boil over high heat, then reduce to a gentle boil and cook until the cauliflower is very tender and easily pierced with a fork, about 12 to 15 minutes.
Drain very well: Drain the cauliflower and garlic in a colander, then let them sit for 3 to 5 minutes so excess steam can escape. This step keeps the mash thick and not watery.
Mash with butter and cream: Transfer the drained cauliflower and garlic to a large bowl or back into the empty hot pot. Add the butter and heavy cream. Using a potato masher, hand mixer, or immersion blender, mash or blend until the mixture is very smooth and velvety. For the cloud-like texture, an immersion blender or hand mixer works best.
Adjust seasoning and texture: Taste and add more salt if needed. If you want it richer, blend in an extra tablespoon of butter or a splash more cream until it’s as creamy as you like.
Serve with buttery swirls: Spoon the mash into a serving bowl, then use the back of a spoon to create soft swirls on top. Melt a little extra butter and drizzle it into the swirls so it pools in the ridges. If you like, lightly mash one of the cooked garlic cloves on top for visible garlicky specks. Serve hot.
Variations & Tips
For extra garlic flavor, roast the garlic instead of boiling it: wrap a whole head of garlic in foil with a drizzle of oil and bake at 400°F until soft and golden, then squeeze a few cloves into the mash. For a lighter version, swap half of the heavy cream with warm chicken or vegetable broth. If you have picky eaters, start with just 1 or 2 cloves of garlic and blend very smooth so there are no visible bits—kids tend to like it more when it looks like classic mashed potatoes. You can also stir in a small handful of shredded Parmesan or cheddar for a cheesy twist, or a spoonful of sour cream for extra tang and richness (this will add to the ingredient count, but is great for non-holiday nights). To make it ahead, prepare the mash, cool, and refrigerate; reheat gently on the stove over low heat with a splash of cream, then refresh with a pat of butter right before serving so it looks and tastes freshly made.
