Roasted Garlic Cauliflower Mash Comfort Creamy Perfection

Jump to Recipe

This Roasted Garlic Cauliflower Mash is silky-smooth, deeply comforting, and a healthier alternative to traditional mashed potatoes that tastes just as indulgent. Sweet, caramelized garlic meets creamy cauliflower in a velvety side dish that’s elegant enough for holiday tables yet simple enough for weeknight dinners.

I stumbled on this recipe when I needed a lighter side for a Sunday roast and haven’t looked back since. The roasted garlic trick turns what could be bland into something genuinely crave-worthy, and I love that it holds its own next to rich mains without weighing you down.

Why This Works

  • Texture heaven: Draining the cauliflower thoroughly and blending with warm cream creates a velvety, cloud-like consistency that rivals any potato mash.
  • Sweet, mellow depth: Roasting the garlic transforms harsh bite into caramelized, almost buttery sweetness that defines the entire dish.
  • Make-ahead magic: Prep up to two days in advance and reheat gently, making holiday hosting or meal prep a breeze without sacrificing quality.

Let’s Make Roasted Garlic Cauliflower Mash

Getting that garlic golden: Start by preheating your oven to 200°C (400°F) and slicing the top off your garlic bulb to expose all those cloves. Drizzle with olive oil, sprinkle with salt, wrap it up tight in foil, and let it roast for 40 to 45 minutes until it’s golden and completely soft (your kitchen will smell AMAZING).

While the garlic does its thing: Bring your stock to a boil in a large pot and add the cauliflower florets. Simmer covered for 12 to 15 minutes until they’re fork-tender and almost falling apart, then drain thoroughly in a colander and shake off every last drop of moisture (this is the secret to creamy, never-watery mash).

Now for the magic: Return that drained cauliflower to your warm pot and add the butter, letting it melt while you stir. Squeeze out those soft, sweet roasted garlic cloves (they’ll slip right out), mash them into a paste, and add them along with the warm cream, salt, and white pepper.

Blend it smooth: Grab your immersion blender (or transfer to a food processor) and blend for 2 to 3 minutes until the mixture is completely smooth and velvety. Pro tip: Don’t rush this step; the longer you blend, the silkier it gets. Taste, adjust seasoning, and serve immediately with a sprinkle of fresh chives on top.

Should you lick the spoon? Absolutely. Will anyone judge you for going back for seconds? Not if they’ve tasted it.

  • 120 ml (½ cup) heavy cream, warmed
  • 1 teaspoon fine sea salt
  • ½ teaspoon white pepper
  • 2 tablespoons fresh chives, finely chopped (optional, for garnish)

Instructions

  1. Roast the Garlic:
  2. Preheat oven to 200°C (400°F).

Notes

Cheesy upgrade: Fold in 60 g (½ cup) grated Parmesan or sharp white cheddar after blending for extra richness and a subtle tang that plays beautifully with the sweet garlic. Truffle luxury: Add 1 to 2 teaspoons of truffle oil just before serving for luxurious, earthy notes that make this feel like a special-occasion dish. Vegan adaptation: Swap the butter for vegan butter and use full-fat coconut cream or cashew cream instead of heavy cream. The result is just as silky and indulgent.

FAQs

Can I make this ahead?

Yes! Prepare up to 2 days ahead and store in an airtight container in the fridge. Reheat gently on the stovetop with a splash of extra cream to restore that silky texture.

Why is my mash watery?

The culprit is always excess moisture. Make sure you drain the cauliflower extremely well and shake off all the water before blending. A few extra shakes in the colander makes all the difference.

Can I skip roasting the garlic?

Fresh garlic will work in a pinch, but roasted garlic provides that sweet, mellow, caramelized depth that truly defines this dish. It’s worth the extra time!

What if I don’t have an immersion blender?

A food processor or high-speed blender works perfectly. Just blend in batches if needed and scrape down the sides for the smoothest, creamiest results.
