What You’ll Need
Ingredients:
- 1 large head of cauliflower (about 5–6 cups florets)
- 1 whole garlic bulb
- 2 tablespoons olive oil (for roasting)
- 2 tablespoons butter (or ghee for paleo/Whole30)
- ¼ cup heavy cream or coconut cream
- Salt and freshly ground black pepper to taste
- Optional: grated Parmesan or cream cheese for extra creaminess
- Optional garnish: chopped parsley or chives
Tools:
- Baking sheet for roasting garlic
- Large pot or steamer basket
- Blender or food processor
- Fine mesh strainer or clean kitchen towel (optional, to remove moisture)
Step 1: Roast the Garlic for Maximum Flavor
Roasted garlic is what transforms this simple vegetable mash into a gourmet experience.
- Preheat your oven to 400°F (200°C).
- Slice the top off a whole garlic bulb to expose the cloves.
- Drizzle with olive oil, wrap in foil, and roast for 35–40 minutes until soft, golden, and aromatic.
- Let it cool slightly before squeezing out the roasted cloves.
Pro Tip: You can roast several garlic bulbs at once and refrigerate or freeze them for later. They add magic to sauces, soups, and dressings!
Step 2: Cook the Cauliflower Until Tender
- Prepare the florets: Cut your cauliflower into even-sized florets for even cooking.
- Steam or boil until fork-tender (about 10–12 minutes). Avoid overcooking—it can make your mash watery.
- Drain well: Let the florets sit in a strainer or pat them dry with a towel to remove excess moisture.
Step 3: Blend to Creamy Perfection
- Add the cooked cauliflower to a food processor or blender.
- Add roasted garlic, butter, and cream.
- Blend until silky smooth, scraping down sides as needed.
- Season with salt and pepper to taste.
If it’s too thick, add a tablespoon of cream at a time until you reach your desired texture.
Step 4: Customize Your Flavor
Here’s where you can make your Roasted Garlic Mashed Cauliflower truly yours:
- Cheesy Option: Add ¼ cup grated Parmesan, cheddar, or cream cheese for richness.
- Herb Upgrade: Stir in chives, parsley, or thyme for a burst of freshness.
- Dairy-Free: Swap butter for olive oil and cream for coconut cream or almond milk.
- Spicy Kick: Add roasted jalapeños, cayenne, or smoked paprika.
Step 5: Serve and Savor
Spoon your mashed cauliflower into a serving dish and drizzle with melted butter or olive oil. Garnish with fresh herbs, roasted garlic bits, or a sprinkle of cheese.
Perfect Pairings:
- Grilled chicken or steak
- Roasted salmon or cod
- Thanksgiving turkey
- Braised short ribs or meatloaf

Tips for the Creamiest Mashed Cauliflower
- Steam Instead of Boil: This reduces moisture, giving you a fluffier mash.
- Drain Well: Excess water can make the texture runny.
- Use a High-Powered Blender: Smooth texture comes from good blending.
- Add Fats Slowly: Cream, butter, or oil should be added gradually to avoid separation.
Common Mistakes to Avoid
- Not draining the cauliflower enough – leads to watery mash.
- Skipping the roasted garlic – raw garlic tastes harsh.
- Over-blending – can make the texture gummy.
- Using cold butter or cream – warm ingredients blend more smoothly.
