featured image for: 8 creamy low carb vegetable mash recipes

Mashed potatoes are great, but have you met their low-carb cousins? These creamy vegetable mashes are silky, cozy, and absolutely loaded with flavor—without the carb crash. We’re talking buttery, herby, garlicky bowls of joy that go with everything from roast chicken to plant-based mains. The best part? They’re fast, flexible, and weeknight-friendly. Let’s mash things up.

1. Luxurious Garlic-Parmesan Cauliflower Mash You’ll Swear Is Potato

An overhead shot of a luxurious garlic-Parmesan cauliflower mash swirled into soft peaks in a matte white bowl, finished with melted unsalted butter puddles, a drizzle of heavy cream, and a snowfall of freshly grated Parmesan; three peeled garlic cloves and raw cauliflower florets scattered on a cool marble surface, with a rasp grater and a warm, creamy white/beige palette emphasizing silky texture; natural window light, no people.

This is the gateway mash that converts skeptics. It’s lush, garlicky, and as spoonable as the classic potato version—just lighter, silkier, and totally low-carb. Serve it under juicy steak or with roasted salmon and watch it disappear.

Ingredients:

  • 1 large head cauliflower, cut into florets (about 6 cups)
  • 3 cloves garlic, peeled
  • 3 tablespoons unsalted butter
  • 1/4 cup heavy cream (or full-fat coconut milk)
  • 1/3 cup freshly grated Parmesan cheese
  • 1/2 teaspoon kosher salt, plus more to taste
  • 1/4 teaspoon black pepper
  • 2 tablespoons cream cheese (optional, for extra creaminess)
  • Chopped chives or parsley, for garnish

Instructions:

  1. Add cauliflower and garlic to a pot, cover with water, and season with a big pinch of salt. Boil until very tender, 10–12 minutes. Drain well.
  2. Return cauliflower to the warm pot and let steam-dry for 2 minutes (this prevents watery mash).
  3. Add butter, cream, Parmesan, salt, pepper, and cream cheese (if using). Blend with an immersion blender until silky. Alternatively, process in a food processor until smooth.
  4. Taste and adjust seasoning. Garnish with herbs and an extra dusting of Parmesan.

Serve with roasted meats or sautéed mushrooms. For a twist, fold in roasted garlic, a splash of truffle oil, or crispy bacon bits. Want it cheesier? Swap Parmesan for aged cheddar. Trust me, this one’s dangerous.

2. Buttered Broccoli Mash with Lemon Zest and Almond Crunch

A 45-degree plated presentation of buttered broccoli mash with grated Pecorino Romano, bright lemon zest ribbons, and a crunchy almond sprinkle on top; the mash is vibrant green with glossy butter and extra-virgin olive oil sheen, served in a shallow stoneware bowl; a halved lemon, whole almonds, and a small dish of olive oil styled to the side; crisp, fresh mood with bright highlights.

Broccoli gets a glow-up with butter, a whisper of lemon, and a crunchy almond topper. It’s savory, bright, and surprisingly elegant—perfect for grilled fish or a quick weeknight chicken.

Ingredients:

  • 5 cups broccoli florets (fresh or frozen)
  • 2 tablespoons unsalted butter
  • 2 tablespoons extra-virgin olive oil
  • 1/4 cup grated Pecorino Romano or Parmesan
  • Zest of 1 lemon
  • 1 to 2 tablespoons lemon juice (to taste)
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • Pinch of red pepper flakes (optional)
  • 2 tablespoons toasted sliced almonds, for garnish

Instructions:

  1. Steam broccoli until very tender, 7–9 minutes. Drain and pat dry if watery.
  2. Transfer to a bowl. Add butter, olive oil, Pecorino, lemon zest, lemon juice, salt, pepper, and red pepper flakes.
  3. Mash with a potato masher for a rustic texture, or blend with an immersion blender for creaminess.
  4. Top with toasted almonds just before serving.

Great with seared shrimp or roast chicken. Swap almonds for pistachios, or add a spoon of ricotta for extra velvet. If you love zing, finish with more lemon and a sprinkle of flaky salt.

3. Silky Celery Root Mash with Browned Butter and Thyme

A close-up of silky celery root mash infused with browned butter and thyme: visible golden-brown butter flecks and tiny thyme leaves marbled through the pale cream mash; served in a warm taupe bowl with a butter-browned spoon resting on the rim; raw celery root cubes and an optional turnip/parsnip wedge blurred in the background; cozy, autumnal lighting emphasizing velvety texture.

Celery root (celeriac) brings earthy, subtle sweetness that feels fancy without trying. Browned butter makes it nutty, thyme makes it cozy, and your dinner table gets very, very happy. This is steakhouse-level comfort.

Ingredients:

  • 2 medium celery roots, peeled and cubed (about 5 cups)
  • 1 small turnip or parsnip, peeled and cubed (optional, 1 cup)

Instructions:

  1. Boil celery root (and turnip/parsnip, if using) in salted water until very tender, 15–18 minutes. Drain well.
  2. In a small pan, melt butter over medium heat with the garlic clove. Cook until butter turns golden and smells nutty, 3–4 minutes. Discard garlic.
  3. Blend celery root with browned butter, cream, salt, pepper, and thyme until ultra-smooth.
  4. Warm briefly on low heat if needed and adjust seasoning.

Serve under pan-seared steak or with roasted mushrooms and a drizzle of good olive oil. For a dairy-free version, use ghee and full-fat coconut milk. Add horseradish for a feisty steak-night twist.

  4. Stir in parsley. Drizzle with more olive oil before serving.

Top with grated Pecorino or crumbled feta for a salty kick. Feeling bold? Add a spoonful of Dijon. This mash is also fantastic as a bed for lemony chicken thighs.

5. Cheesy Cauli-Broccoli Mash with Crispy Shallot Topping

A straight-on casserole shot of cheesy cauli-broccoli mash: bubbling sharp cheddar and Parmesan top with a golden, crispy shallot topping, flecks of Dijon visible at the edges; a serving spoon lifts a scoop to reveal the creamy green-and-white mash beneath; steam rising, set on a rustic baking sheet with a small dish of extra crispy shallots and shredded cheddar in the foreground.

When you can’t decide between cauliflower and broccoli, mix them and add cheese. The crispy shallots seal the deal with texture and sweet-savory crunch. It’s family-friendly and secretly veggie-packed.

Tips For Ultra-Creamy Low-Carb Mashes

Want them restaurant-smooth? Here’s how to nail it every time.

  • Drain, then steam-dry: After boiling or steaming, let veggies sit in the hot pot for 1–2 minutes to evaporate excess water.
  • Blend smart: Immersion blenders make everything silky. Food processors work too—just don’t overwork fibrous veg.
  • Boost fat: Butter, olive oil, cream, or cream cheese add that velvet finish.
  • Season last: After blending, taste and adjust salt, acid (lemon), and heat (pepper flakes).
  • Garnish for texture: Toasted nuts, crispy shallots, or herb oil make it feel fancy.

Make-Ahead, Reheat, and Storage

  • Make-ahead: Most mashes keep 3–4 days in the fridge. Reheat gently over low heat with a splash of cream or broth.
  • Freezer-friendly: Cauliflower, celery root, and parsnip blends freeze best. Thaw overnight and reblend with a bit of butter or cream.
  • Meal prep move: Portion into ramekins, top with cheese, and broil until bubbly when ready to serve.

There you go—eight creamy, low-carb vegetable mash recipes that bring the comfort without the carb coma. Pick one tonight, add a simple protein, and you’ve got dinner magic. Once you start mashing veggies like this, you won’t stop. Which one are you making first?
