Keto Cauliflower Mash with Butter
Mashed potatoes are the ultimate comfort food on a plate, creamy, mild and buttery. On keto you can get remarkably close to that feeling with cauliflower. Three things matter: cauliflower cooked until truly soft, plenty of butter, and patience while blending. Each serving of this mash delivers 4 g net carbs, 24 g fat and 6 g protein, compared to the roughly 35 g of carbs in a portion of classic mashed potatoes.

Preparation
Trim the cauliflower, break it into florets and peel the stems. Put everything in a pot, cover with just enough water and add 1 tsp of salt. Simmer for 12 to 15 minutes until soft. The cauliflower really must be tender, otherwise the mash turns out grainy. The most important step: drain it well. Tip the cauliflower into a sieve and let it rest for at least 5 minutes, pressing gently with the back of a spoon so the water escapes. For best results, transfer the drained florets onto a clean kitchen towel and squeeze them gently dry. Place the cauliflower in a tall blending jug, add 60 g of room-temperature butter, 100 ml of cream and a pinch of freshly grated nutmeg. Blend with an immersion blender for 1 to 2 minutes until you have a velvety, pale-beige mash. Season with salt and white pepper. If you prefer a coarser texture, press the cauliflower through a potato ricer instead of blending.
Why does cauliflower mash come so close to the real thing?
Cooked cauliflower has a texture similar to soft potato, slightly floury with a gentle bite. Its own flavour is mild enough that butter and cream dominate. That combination, starch (or in this case cauliflower flesh), dairy fat, salt and nutmeg, is exactly what defines the classic mashed-potato taste. The starch is missing, but the cream aroma covers the gap well.

How can I vary the mash?
Cheese version: stir 50 g of grated Parmesan or aged Cheddar into the hot mash for extra savouriness and an even creamier texture. Garlic mash: cook two garlic cloves together with the cauliflower and blend them in. It tastes almost like French pommes purée. Horseradish version: stir 1 tsp of jarred horseradish in at the end. It pairs sensationally with roast beef or salmon. For an even richer result, swap the cream for 80 g of cream cheese. It makes the mash firmer and more cheese-like, perfect alongside braised dishes.
Tips for creamy cauliflower mash
- Cook the cauliflower truly soft, otherwise the mash turns grainy.
- Let it drain for at least 5 minutes before blending.
- Use an immersion blender for the silkiest texture.
- Add the butter at room temperature so it doesn't clump.
- Nutmeg and white pepper are the classic mashed-potato spices.

FAQ
Does the mash taste like cauliflower?
If the cauliflower is well drained and blended with plenty of butter and cream, the cabbage flavour fades into the background. Nutmeg helps even further. Most tasters don't immediately recognise the main ingredient.
Can I reheat the mash?
Yes, it reheats well. Warm it gently in a pot over low heat while stirring, adding a splash of cream if it has firmed up too much. In the microwave, use 600 watts in two short intervals with a stir in between.
Can the mash be frozen?
It's possible, but the texture suffers a little. After thawing, stir it vigorously and beat in a knob of fresh butter. The mash keeps for around 3 months in the freezer.
