Creamy Garlic Mashed Cauliflower Recipe

I’ve always loved breads, potatoes and pastries, but in recent years I cut back on carbs for health reasons. Swapping a few ingredients at meal times has made a big difference without sacrificing flavor. Mashed cauliflower is one of those swaps that delivers indulgent texture with fewer carbs.

This Garlic Mashed Cauliflower has become our go-to low carb side. At first I wondered if it could replace classic mashed potatoes, but the results are pleasantly surprising — creamy, rich, and satisfying without the heaviness.

Cauliflower has a mild, adaptable flavor once cooked, which makes it an excellent base for butter, cream and seasonings. When pureed, it takes on a silky texture that’s remarkably close to mashed potatoes, especially when finished with warm butter and a splash of cream.

This is a great winter recipe and pairs well with seasonal mains. The technique works for many variations, so feel free to adapt the richness or add herbs to suit your plate.

Why you’ll love this recipe:

• Silky, creamy texture with gentle garlic flavor and fresh chopped chives.
• A small amount of butter and cream adds luxurious richness without overwhelming the dish.
• Mild cauliflower flavor makes it a flexible base for additional herbs or spices.
• Gluten-free, low carb and keto friendly; easily made dairy-free by swapping butter and cream for olive oil, dairy-free butter or coconut milk.

Recipe ingredients

This version of mashed cauliflower uses just a few simple ingredients to deliver a smooth, comforting side. A bit of fat and a touch of dairy (or a substitute) will give the finished mash body and flavor.

• Cauliflower — A whole head is the most economical choice. Prep into uniform florets for even cooking.
• Butter and cream — Add richness and a smooth mouthfeel. For dairy-free, use olive oil, vegan butter or coconut milk.
• Garlic — A few cloves add warmth and depth; roast or boil with the cauliflower.
• Chives — Provide a fresh, mild onion note. Swap for other fresh herbs if preferred.
• Salt and pepper — Simple seasoning to taste.

How to cut cauliflower

You can buy pre-cut florets for convenience, but buying and trimming a whole head is generally more economical and reduces packaging. A 2.5–3 lb head yields about 7–8 cups of florets.

1. Wash and dry the cauliflower. Place it stem-side up on a cutting board and slice it in half through the core.
2. Cut out the core by slicing along each side, then break or cut the head into florets.
3. Trim larger florets so pieces are roughly the same size for even cooking.

How to make cauliflower mashed potatoes

Once the cauliflower is prepped, this recipe is quick. Let the butter and cream come to room temperature as the cauliflower cooks for a smoother texture when combined.

Pro tip: An immersion blender is the most convenient tool for puréeing directly in the pot. If you don’t have one, a food processor or high-speed blender works well, too.

Full instructions are in the recipe card below.

1. Place butter and cream on the counter to warm slightly. Put cauliflower florets and garlic in a large pot and add enough water to cover by about 1 inch. Cover, bring to a boil, then reduce heat and simmer 10–15 minutes until very tender.
2. Drain the cauliflower thoroughly in a colander to remove excess water.
3. Return cauliflower to the pot and purée with an immersion blender until smooth. Alternatively, purée in a food processor or blender in batches.
4. Stir in butter, heavy cream, salt, pepper and chopped chives until combined. Adjust seasoning and serve warm.
